Introducing CRH
CRH plc was formed through a merger in 1970 of two leading Irish public companies, Cement Limited (established in 1936) and Roadstone, Limited (1949). The newly-formed group was the sole producer of cement and
the principal producer of aggregates, concrete products and asphalt in Ireland. In 1970, the Group had sales of
c.€27m, c.95% in Ireland.
Since that time, CRH’s strategic vision has been to be a responsible international leader in building materials,
delivering superior and sustained shareholder returns, while reducing its dependence on individual markets and
achieving a balance in its geographic presence and portfolio of products.
1970‘s
Following its foundation in 1970 CRH broadened its horizons in 1973 with its first acquisition on Mainland Europe,
Van Neerbos, a Dutch-based builders merchant with some
concrete products operations.
In 1996 the purchase of Tilcon for $323 million was CRH’s
largest acquisition at that time, establishing a unique
regional position in materials in the Northeastern US. The
acquisition of Allied Building Products gave CRH a fifth core
business in the US and a first presence in distribution.
1978 saw the first move into the United States with the
acquisition of Amcor, a concrete products company based
in Utah. By the end of the 1970s CRH had sales of €328
million and profit before tax of €31 million having spent
€43m on 16 acquisitions.
In 1998, an initial 50.7% stake in the Ibstock clay brick
business was acquired in the UK. While in Ireland, one of
the largest automated block plants in the world, with an
automated capacity of 30 million units, was opened at
Roadstone Dublin’s Belgard Quarry complex.
1980‘s
In the 1980s, CRH invested in its Irish operations by completing major modernisations to its two cement works; the
largest capital project carried out by an Irish company up to
that time. Relative to its market capitalisation, this remains
the largest single development project carried out by CRH.
1999 saw investments in glass tempering in Chile, cement
in the Ukraine together with the acquisition of Finnsementti
and Lohja Rudus which gave CRH a leading market position in cement, aggregates and concrete products in Finland,
a first presence in the Baltic region and a strengthened
position in concrete and aggregates in Poland.
The foundation of what is now our Americas Materials Division commenced in 1985 with the acquisition of Callanan
Industries, an aggregates and asphalt company in Upstate
New York. CRH’s presence in mainland Europe grew in
1987 with the acquisition of the Beton Catalan Group,
a major producer of aggregates, concrete products and
readymixed concrete in Spain. By the end of the 1980s,
CRH had sales of €1.3 billion and operations in 7 countries
having spent €440 million on a further 49 acquisitions.
By the end of the 1990s after spending €3.8 billion on 189
acquisitions, CRH was a group with sales of €6.7 billion,
and profits before tax at a new record high level of €635
million.
1990‘s
In 1990 CRH invested in 13 glass fabrication plants which
formed the basis for the highly successful Oldcastle Building Envelope product group that exists today. 1995 saw
the first investment in cement manufacturing outside of Ireland through a shareholding in Cementownia Ozarów - one
of the leading Polish cement producers; a minority stake in
a major ceramictile manufacturer in Argentina; CRH’s first
position in Canada with the acquisition of Wescan glass fabrication business; and the establishment of a new growth
area for the Americas Materials Division with the acquisition
of Staker, a major quarry and blacktop business in Utah
and the mountain states.
4 | Introducing CRH
2000‘s
In 2000, our Europe Materials team acquired the Jura
Group in Switzerland, a further step in expanding CRH’s
cement and aggregates presence in Europe, also with a
distribution business with scope to add value with the support of CRH’s existing European distribution group.
In 2003, CRH completed its biggest deal to date with the
acquisition of Cementbouw, a leading Dutch building materials group with DIY, merchanting and building products
operations and a 45% joint venture stake in Cementbouw’s
cement trading and readymixed concrete operations.
The major acquisition of 2004 was the 49% joint venture
stake, with joint management control, of Secil, a major Portuguese manufacturer of cement and readymixed concrete.
2006 acquisitions included Ashland Paving And Construction (APAC) for US$1.1 billion (net of disposals), the largest
In 2014, CRH spent €190 million on 21 acquisitions across
the United States and Europe. We initiated an active divestment programme and generated disposal proceeds of
€350 million from 16 transactions. It was a year in which we
also reorganised our European business. The company has
now integrated the heavy materials business in Europe with
its concrete and clay products businesses into one Europe
Heavyside organisation and created a new Europe Lightside products segment. This reorganisation will enable the
Group to better leverage the benefits of its operating plant
network in European markets.
In August 2015, CRH acquired a global portfolio of assets
from Lafarge-Holcim for an Enterprise Value of €6.5bn.
This deal doubled CRH‘s cement volume, and expanded
the Group‘s cement, aggregates and readymix concrete
portfolio. As a result, CRH is now a top 3 building materials
player globally and the world No. 2. in aggregates. The new
businesses have an excellent strategic fit with CRH‘s existing portfolio. Together, they offer significant opportunities
for synergies, and provide four major global platforms from
which we can grow CRH in the years ahead.
single transaction completed by the Group. Significant
transactions in 2007 included 50% acquisition of Denizli
Cement (Turkey) and 100% acquisition of Harbin Sanling
Cement (China).
2008 saw major changes in the financial, economic and
business climate worldwide, which necessitated a significant shift in CRH‘s short-term focus and a curtailment of
development activity as the economic environment deteriorated. Acquisitions completed included a 50% stake in MyHome Industries Limited (MHIL), an Indian cement producer
with strong market positions and excellent reserves in the
Andhra Pradesh region of SE India. In 2009 CRH increased
its emerging market exposure by acquiring a 26% stake
of Yatai Cement, the leading cement manufacturer in NE
China with 14Mt of cement capacity at time of purchase.
By the end of the 2000s, CRH had sales of €17.4 billion
having spent €13.7 billion on a further 520 acquisitions.
2010‘s
In 2010, the Group completed the buyout of the Bauking
distribution business, which greatly strengthened CRH’s
existing position in Germany. 2011 saw the acquisition of
VVM Group, a major distributor of cement, readymixed
concrete and other building materials in the Netherlands,
yielding purchasing and logistics synergies in combination
with our existing Benelux-based Cementbouw business.
In 2013, major transactions included the acquisition of
Mykolaiv Cement, Ukraine and Sree Jayajothi Cements Ltd
in South India, and also Expocrete, a leading manufacturer and distributor of hardscape and masonry products in
western Canada.

5 | Introducing CRH
Ready for new challenges
It‘s not Josef Nowak‘s thing to remain in the comfort zone. So the Managing
Director of CRH Vienna & CRH White is ready for a new start.
Already at the first day of the brand change in early September there was no more trace of „Holcim“
at the company‘s headquarter in Franzosengraben 7, Vienna. The team around CRH Vienna‘s Managing Director Josef Nowak is fully present in the new parent company, CRH, and wants to start
right away, after a few months of uncertainty, back with full force. In an interview Josef Nowak talks
about changes and new goals.
Since 1 September, Holcim Vienna is now called CRH
Vienna. New name, new good fortune?
Josef Nowak: For our customers, nothing has changed,
really. Our team is the same, the products and services
as well, and also the C³ Atelier and our cluster has remained unchanged. What‘s new is that we now belong
to a group which is diversified in different segments of
building materials, and is well established in the market.
As a result, we receive additional input from other areas,
and will in the future be able to supply more customer-specific solutions and products.
Until now, CRH has not had its own brand. This strategy has changed in the Austria Slovakia Hungary cluster, and also in the area of white cement. Why?
The Group is generally very market-driven in its operation, and attaches great importance to adjusting to the
current circumstances of the market and industry. So
6 | Interview Josef Nowak
nothing was imposed on us in terms of finding a new
name. The desire to act in the market as „CRH“ was our
own. Of course, completely new names were considered as well, but „CRH“ is a strong brand that is currently
on everyone‘s lips. The logo is short and concise.
Shares in Lafarge and Holcim: CRH has shelled out EUR
6.5 billion - a sum which you must earn back. Does that
have implications for future investment, such as in the
Rohožník plant?
We have already invested a lot in modernisation, reduction of CO2 emissions and safety in recent years. As a
result, our production facility in Rohožník, Slovakia, is
one of Europe‘s most modern plants. We have a new
rotary kiln and a salt production plant adopting the hot
disc procedure, use renewable fuels and work with heat
recovery. Also, under CRH, investments to make our
production more environmentally friendly will be made.
That is, the best value principle has yet to reach the
construction industry?
At some clients such as ÖBB (Austrian Federal Railways) and Asfinag, there has been some rethinking
already. They also saw that the lowest price is not
always the best. Of course, price is important, but so
too is the quality of the products and services, and also
personal relationships with the customers.
Excellence in White
If it were up after the EU, could the CO2 savings be
further optimized?
We and all cement producers have now reached the
point where we can hardly optimize anything more. In
this regard, politicians unfortunately do not understand
our processes, and lobbying has hardly any effect. Therefore, the entire industry should more actively publicize the theme „heating and cooling,“ because through
this, significant CO2 economies are possible with concrete - although not in the manufacturing process but in
the operation of the building. Here especially, government policy would be needed to make this technology
more interesting, through subsidies or tax incentives.
Speaking of policy: The construction industry has
criticized the lack of investment in infrastructure and
the still unrealised housing package. How has the year
been going?
In Slovakia, the business is currently evolving very well,
because the construction industry is booming - thanks
to EU funding, and also to renewed private investment.
In Austria, no stimuli are provided by the government.
I don‘t know what they are waiting for. I‘m also afraid
that the housing initiative will be postponed even
longer.
The government currently has quite different concerns,
because of the refugee issue. The result, however, is a
very weak ordering situation, and we are lagging behind
our sales expectations in Austria. This situation, and the
restructuring in the industry, increase competition, of
course.
Personal relationships and networks are also focused
on in the C³ Atelier. How are you proceeding there?
The C³ Atelier and the ideas behind it were received
with great enthusiasm at CRH, and immediately integrated into the group. Within the C³ Atelier, the focus
will increasingly be on brainstorming and networking.
Since our founding five years ago, there has been
some successful collaboration among the members,
and transactions as well. Sharing is one of my favorite
words. We want to continue to promote and further
such exchange.
As well within the CRH group?
Of course we are also working on that, to accommodate our ideas and projects in other CRH countries, in
order to bring cement and concrete more sharply into
focus. This is an issue that the CRH Group has not
yet brought to the fore, because it has focused very
strongly on individual regions and markets . But I think
that through internal networking, we can raise up people with a great deal of potential in the group.
What expectations do you have for the coming years?
It is increasingly difficult to make a forecast. Of course
we want growth - who doesn‘t? But I‘m very careful
with my expectations in terms of grey cement. Unfortunately, a hard winter can affect a year very quickly.
In the area of white cement, we are happily more than
satisfied. Also, some companies that have a great
need for white cement belong to CRH.
Sounds like the challenges will not diminish in the near
future...
If there are no challenges, one moves in a comfort
zone, and one should never be too comfortable. I really
appreciate the reboot and the challenge. New experiences in the CRH group are awaiting us, and we will
make the best of them

Renovation of the Rudas Bath in Budapest
Oriental design with
White cement
The Rudas Bath in Budapest was built over 400 years ago and is still in use today. In order to
remain attractive for its visitors, it had to be renovated. Among other things, the facade benefited from that. It was upgraded with oriental-style concrete elements made out of CRH White
Cement.
T
he most famous sights of Budapest include its
world-renowned spas. They awarded the Hungarian capital with the nickname „spa town“ - and
rightly so, because the bathing has a 2000 year old
tradition here. Already the Roman founders took advantage of the resources of nature. The still-functioning
bathrooms are mainly from the decades of the Turkish
occupation. The Rudas Bath was first mentioned in
1597 and continues to offer its visitors a relaxing respite.
To enhance this, the management decided to renovate
the spa in end of 2014.
The renovation work lasted a year. In addition to that, the
bath got four new swimming pools, saunas, a restaurant
and a café. A special highlight of the renovation is the
new roof terrace. In addition to a pleasantly tempered
Jacuzzi, it offers an impressive view of the directly adjacent Danube and the city.
Front
But not only the visitors of the Rudas Bath benefit from
the renovation. The passers-by of the building can experience the improvement first hand, because the facade
of the south wing enjoys a sensational design. It consists
of snow-white concrete elements that are designed with
a girih decor.
These timeless, aesthetic ornamentation have already
been used by the inhabitants of the Ottoman Empire.
It is based on five basic designs that consist of simple
polygons. All edges have the same length. Each theme
has a simple pattern, whose lines bisect the edges. If
the elements are combined with one another, a net-like
design with or without periodic repetitions is created.
For the reconstruction of the Rudas Bath, this ornamentation was used for 21 grating elements and 40 surface-structured precast elements.
They are complemented by 67 plain white panels, that
were built primarily in the base area. Ivanka Factory &
9 | Rudas Bad Budapest
Design Services from Budapest took over the preparation of these extremely graceful concrete elements
Manufacture of precast elements
This leading Concrete Design brand is known for its
advanced design and outstanding technical solutions
round off the concrete topic. The company has set itself
the goal of using a material that is considered by many
as rough and industrial for producing special design
elements.
The company demonstrates a holistic approach and is
different from a normal precast concrete component
plant in many ways. For example, it also offers services
and products in the field of architecture, design and
engineering, as well as in research and development.
In the production of white concrete elements, concrete
specialists rely on the CRH White Cement for years.
White cement
It is available on the market under the name CRH White
and is distinguished by its bright white color. It is also
10 | Rudas Bath Budapest
the reason why many concrete producers opt for this
cement when it comes to producing high-quality white-faced concrete elements.
Besides, this cement doesn´t rank behind it´s grey
counterpart, even in technical respect. Also bulky components can be realized well with it. CRH White offers
another advantage when the concrete is dyed: Pigmented concrete elements, which were produced with the
CRH White Cement, appear much more brilliant than it is
possible with its gray counterpart.
Considering these advantages it becomes quickly
apparent that it has been a good decision to trust the
CRH White cement for the Rudas Bath. The person in
charge managed to combine two opposing design ideas
with the precast elements made of it. On one hand, the
facade appears clear, modern and restrained thanks to
the choice of materials. On the other hand, it looks playfully oriental because of girih decor. A paradox, through
which the building will certainly attract many glances in
the future and perhaps attract additional bath visitors.

On a good way: White cement
for a particular school
In Freiburg, the Robert Bosch United World College is opened. In the open space design CRH White Cement is used.
A
t the end of last year, the first United World College (UWC) in Germany was opened in Freiburg.
In this High school, students from all around the
world (71 nations) and from all social classes are taught
equally. It happens so that a street child, a refugee boy
and a professor’s daughter live and learn together for
two years. They are selected solely according to their
suitability and talent. A comprehensive scholarship
makes sure that all students can afford to attend school.
In the end, the visitors graduate from College with the
„International Baccalaureate“, a globally recognized university entrance qualification. The trails and supporting
slopes were made by Adolf Braun KG, Teningen, using
the white cement from CRH (Slovensko) a.s.
Learning in monumental spaces
The UWC Robert Bosch College is a joint project of
the Robert Bosch foundation and the German foundation UWC. The school is also supported by the state
of Baden-Württemberg. Overall, it offers 200 lesson
courts, where 100 new students per year can attend the
educational institution. These are taught in the monumental, lavishly renovated rooms of a former Carthusian
monastery. To meet the daily boarding justice, those
responsible authorities supplemented the baroque complex with a glass auditorium and a canteen with kitchen.
Besides, with four teacher and eight student houses, a
small housing estate was built, which clings to the steep
slope of the terrain. The single buildings are connected
by concrete paths and stairs of different width, which
give the settlement the tranquil appearance of a mountain village.
CRH White cement
Individual places and slope protections, which can also
be used as a seat, underline this charm. The special
feature of this infrastructure and the slope protection: It
wasn´t built with the usual gray cement, but with white
cement from CRH. If the concrete made of this cement
is dyed, much more brilliant color results in comparison
to the gray cement can be achieved. Also in terms
of strength and handling, CRH White Cement is very
good in comparison with its gray counterpart. With this
successful choice of materials, combined with demanding installation methods, the planners emphasize how
important the ways within the school community are.
Stamped concrete
The Adolf Braun KG from Teningen, a gravel and ready-mix concrete plant, took over the building process. It
was also responsible for setting up the slope protections
of stamped concrete. The production method of this
seemingly archaic walls is now used rarely. The stamped
concrete is a mixture of natural aggregates, water and
cement. Compared to conventional concrete, it is much
drier and not reinforced. The building material got its
13 | UWC College
name because the processors stomped it until it became plastic and showed a closed surface, where a
moisture film has been formed. Prior to the application of
the next layer, typically after one day, the previous one is
roughened, cleaned and moistened, in order to ensure
the adhesion to the next one. If a layer can’t be made in
a full length, the oblique recesses must be made, which
are carried out in opposite directions from layer to layer
in order to achieve a „toothing“. It gives the stamped
concrete elements their typical appearance.
Broom finish
In the construction of paths and steps, the authorities
also resorted to a very down-home installation method:
the broom finish. Here, the concrete is smoothed after
installation and patterned using a broom. This creates a
non-slip, rough surface, which offers increased slip resistance. At the same time, the ambient conditions and
the work performance tremendously influence the result.
To ensure a uniform appearance, the Adolf Braun staff
had to bring a steady hand and a lot of experience.
Whereby the work was additionally aggravated by the
topography, because the slope was quite steep and
some machines could not even be used. All built concretes were mixed in the Adolf Braun KG plant. Because
the elements are outdoors and unprotected, they are
exposed to rain and must fulfill the exposure class XC4,
among others. Due to the use of de-icing agents in winter, the requirements of the exposure classes XD3 and
XF4 had to be met.
When asked why the company chose the White cement
from CRH, the superintendent Hansjörg Lorenz answered: „We already had very good experience with the
CRH White Cement in another object. At that time we
had to color the concrete and had gotten excellent advice from the company‘s employees. If you make such a
good experience, you gladly get back to it again.

P
remac, spol. s r. o. has enjoyed success on the
Slovak construction market and abroad for nearly 25 years. It became a part of the CRH group
in 2003. The company has been an active participant in
many major construction projects in cooperation with its
business partners. It is among the leaders on the market,
thanks to its high quality and broad range of products
including exterior concrete pavers, landscaping elements
and construction materials. Three production plants in
Bratislava, Zvolen and Košice produce thousands of m2
of pavers and slabs every year on fully automated production lines.
Dipl. Ing. Miroslav Leško, Managing Director of Premac,
spol. s r. o.: „The company‘s long-term philosophy is to
meet the needs of customers. By using the global knowhow of our Group in development, environmental protection and design, we are striving to manufacture not
only products that meet the conditions for an upscale
housing, but also to offer services, which are the foundation for the excellent relationships we enjoy with our
partners. Our goal for our products is to deliver the best

DAKO Brno
The company, DAKO Brno, spol. s r.o. was established in March 1996.
The company originally focused on civil engineering
projects and the production of flat prefabricated components used to assemble public toilet modules. The
company‘s focus gradually transitioned to the delivery
and erection of reinforced concrete frame structures
and steel hall structures.
DAKO Brno, spol. s r.o. is currently active in three
basic areas:
The first area focuses on the production and installation of ventilated fronts made of glass fibre reinforced
concrete under the DAKOBET brand.
Another section of the company has cooperated with
the german company Hering Bau to produce maintenance-free and vandalism-resistant public toilet
modules since 1996. It is the exclusive supplier for
the Czech and Slovak markets.
The final category are accessories, which includes large-sized planters under the DAKOBET brand, street
furniture and other non-standard glass fibre reinforced
concrete products.
18 | DAKO Brno
GLASS FIBRE REINFORCED CONCRETE
Products made from glass fibre reinforced concrete
are characterised by excellent physical and mechanical properties and continue to attract attention and
a diverse range of applications in architecture and
construction.
This fact led our company to focus on their development, production and installation. Our experience
resulted in the DAKOBET line, which has established
itself among more traditional construction materials in
the construction industry.
DAKOBET products are characteristic for their high
strength and resistance while remaining relatively low
weight, which significantly decreases transport costs
while simplifying handling and installation.
These advantages are achieved by placing glass
fibres into a basic mixture of Portland cement, sand,
water and other ad-mixes. Fine grained particles in
the composite structure ensure low water absorption
and frost resistance. Our CEM I 52.5 N quick white
cement is supplied by CRH (Slovensko) a.s.

Main DAKOBET material applications
• Ventilated façades
• Architectural details used in facades
• Bridge tiles
• Interior accessories
• Large-volume planters
• Street furniture (benches and round benches)
• Chimney caps
• Balcony panels
• 3D elements

Almost 160 years of company experience and interesting projects in various fields
For the new Daimler Consolidation Center in Speyer W+S Monnerjahn
produced 3.400 precast elements with a total weight of 41.500 tons.
22 | W+S Monnerjahn
T
he W + S GmbH Monnerjahn from Halsenbach (D)
can look back on almost 160 years of company
experience and has been constantly developed
over time. The construction business was founded in
1858 by Phillip Monnerjahn and was originally a 1-man
company. In the meantime it is one of the largest employers in the Hunsrück.
The Construction is based on a powerful reinforced
concrete precast plant. The fields of activity include
structural beam and shell parts made of reinforced
and prestressed concrete, architectural concrete and a
private platform system. The employees of the precast
plant mastered the art of producing high-quality concrete, just as well as the ability to produce huge quantities
in a short time. An example is the Daimler Consolidation
Center in Speyer, for which the company produced 400
finished parts with a total weight of 41,500 tons.
To create the stairs in for
the federal garden show
at castle Koblenz, the
staff of W+S Monnerjahn
used CRH White cement.
Due to its bright white
color they prefer the
cement as well for other
aesthetic components.
1.100 tons of concrete
in 259 precast elements
were installed here.
This logistics center was opened in summer 2015 and
is characterized by an overall length of 1.2 km. In the
national garden show in Koblenz, the precast elements
factory presented it’s skills in the field of architectural
concrete another time and manufactured the elegant
castle steps leading up to the river Mosel. In this project
and in similar challenging fair-faced concrete surfaces
the employees of W + S Monnerjahn rely on the white
cement of CRH.
They prefer it because it is much brighter than comparable white cements and has a lower heat generation.
Thus it can be processed more easily. According to that
the company uses the CRH White cement also for the
latest product: the garden benches of W + S Monnerjahn. These were actually designed and built in 2014 for
a company party, but enjoyed such great demand that
the company decided to include them in their portfolio.
This is a sure sign that the company‘s management
and employees have a keen sense for trends, in broad
outlines and in great detail.

A concrete saling boat is this even possible?
A
few years ago I was packed by a sailing passion.
As I sat one day in a sailboat, I suddenly had an
idea: Are there really concrete sailboats? Could
that work anyway? This question I asked then also the
concrete specialist Dr. Roland Travnicek.
It should be noted here that Mr. Travnicek is an avid ice
sailor, scored top placements in his age group and is
known far beyond our borders in this sport. Dr. Travnicek
is in his professional activities, a highly respected concrete engineer and court-certified expert in the specialized sections Construction/Concrete - and reinforced

In February 2015, the idea was finally concretized:
„Take sails, a mast and accessories of a Laser dinghy
(Olympic boat class), a fuselage made of concrete and
the concrete sailing boat is finished.“ For this, we are
also getting support from Andreas Geritze, who won
a silver medal in the Laser class at Boots the Olympic
Games in Athens 2004.
The C³ Atelier powered by CRH has started the project
„concrete sailboat“ together with some members, to
which we now want to give you an overview to you.
We have been looking for a producer who we found in
Kruno Thaleck, a skilled professional in the art of forming
and concrete.
He is owner of the company B & T in Raubling, Germany, where he has developed the material CEton. He is
furthermore a tinkerer in his area, who is always anxious
in improving and setting higher goals. Success has proved him right here.
Kruno Thaleck gained in 2011 reputation for the project
„Roca Gallery“ in London in the architectural scene,
which he realized together with the star architect Zaha
Hadid. She is currently one of the best known architects
worldwide. At the moment there is no way around, when
it comes to architecture at its fullest. The campus of the
University of Economics, the Berg Isel ski jumping or the
Reinhold Messner Museum on Kromplatz in South Tyrol
may be mentioned here as successful examples of their
joint work.

Kruno Thaleck has already begun with the formwork to
manufacture a mold. This will then become the Ceton
concrete hull forms, which should also be suitable for
swimming course. The mold construction is designed to
enable later further production of more concrete sailing
boats.
With respect to the formwork construction and the
design, there are so far no references or calculation
options, which could be resorted to. This is making the
whole project far more challenging. Furthermore, the
sword and the rudder blade is to be produced from CEton. (On your request I can send you more information
regarding CEton)
The result of the test body is so far very good. By using
the white cement of CRH White, an optic has been
created which makes it difficult to imagine that this hull
was made out of white concrete. As a cement a CEM I
52,5N White from CRH was used.
The hull has a total weight of about 580kg, which still,
however, requires optimization. The wall thickness is
approximately 220mm. The areas for the installation of
daggerboard and mast are already prepared in the hull.
Mr. Thaleck is currently working on them, which will
take some time to complete. After that a water-testing
phase will show how the concrete hull behaves in water
and how items as mast, sail, rudder fittings, etc. can be
operated.

Our goal as C³Atelier powered by CRH is to present a fully functional
concrete sailboat in the summer of 2016 with which we want to carry
out a concrete sailboat regatta on Lake Neusiedl in next fall.
Personally, I am really looking forward to the maiden voyage, when I
will think back to my first thoughts:
„A concrete sailing boat - is this even possible?“
We will keep you updated and would be delighted to welcome you,
dear readers, in this planned regatta. After the completion of the
prototype and testing phases we will be delighted take orders for the
concrete sailing boat.
In case you have any questions about this project, I would be happy
to help!

Litracon Jewellery – the new dimension
of concrete jewellery design
L
itracon Jewellery - translucent concrete jewellery
is the novelty of this winter. The new collection was
born by a new application of an innovative building
material Litracon - Light-transmitting concrete. It merges
concrete with precisious metal, architecture with jewellery design. The creator of the new collection is a jewellery designer, Gabriella Faludi who has been inspired by
the world famous invention of Hungarian architect Aron
Losonczi. The creators have launched the first collections of Litracon Jewellery.
The first collection called „urban” shows the simple
geometrical forms of wooden building blocks. It consits
of 5 types of rings and a medal. Soon cufflinks will be
available for male buyers as well.
The ring and the socket is made of silver. Optionally, it
can be ordered out of white gold and for the lovers of
moderate luxury, rings are available with a small piece of
diamond.
The main speciality of Litracon Jewellery is that it is far
more than it shows at first glimpse. Beyond being a minimal fashion accessory the user will be greatly impressed when hold the pieces against light. The concrete
gemstone will spring to life due to the light permeating
through it.
Each piece of Litracon concrete is fully handmade and
such gemstone includes approximately 20-40 meters
of ultra thin high-quality optical fibre. Due to the various
light patterns, each piece is unique.
Litracon Jewellery® combines timeless simplicity with
modern and innovative way of thinking. In this manner
the hardness of the rough concrete and the hidden playfulness of the jewels become a perfect whole.
About Litracon:
The patent protected Litracon products present the phenomenon of light transmitting concrete in the form of widely applicable new building materials. They have been developed by Hungarian architect Aron LOSONCZI since 2001. In Litracon
Classic (patented in 2002) there are optical fibres used for light transmission while in Litracon pXL (pateted in 2007) specially formed transparent plastic units lead light through the concrete.
Litracon® received numerous international honours: it was listed among the most important inventions of year 2004 by
TIME magazine and received „red dot: best of the best award” in 2005.
