“Architectural concrete gains importance“ 
The BFT International, leading magazine of the precast concrete industry, has picked up on the trend to architectural concrete, by highlighting 3 projects, where the precast concrete producer and long-time HEBAU-customer Hemmerlein Ingenieurbau GmbH (www.hemmerlein.com) has produced special architectural precast concrete for those projects with various kinds of different surfaces.
A: Citygate, CH-Basel: Concrete wall panels with black aggregates and polished surface. After the polishing process those panels were protected by applying HEBAU’s COLORFRESH intensive protective coating, which helped to intensify the black colour, prevents efflorescence and will avoid weathering long-term (completed 2010).
B: Secondary School, D-Gaimersheim: The concrete mix design was based on white cement and a local crushed aggregate, which was micro-exposed with HEBAU’s CSE Deactivator in order to achieve a warm limestone-like surface (completed 2011).
C: CECAD D-Cologne: A project which is currently being produced for world famous Max-Planck-Institute and for which white precast concrete wall panels are being acid-etched with HEBAU’s MICROGEL and protected with HEBAU’s COLORTEC Max protective coating, too. The article illustrates that the building material architectural concrete has great aesthetical and creative potential among architects and specifiers, if presented and produced with enthusiasm and expertise, as Hemmerlein Ingenierurbau GmbH and HEBAU GmbH are doing.

The BetonTage congress in D-Ulm, from 7th to 9th of Febuary 2012. The complete congress program and further information is available under www.betontage.de. As the congress is becoming more and more international, some of the speeches will be held in English language and, if not, there will be a simultaneous interpretation into English. This year a special feature and lectures about Finland’s precast concrete industry will round-up the congress. Correspondingly our HEBAU-catalogue has now also been published in Finish language and is available as download on www.hebau.de.
Mr. Dipl.-Ing. Stefan Heeß from the company Dyckerhoff AG, Germany’s leading producer of white cement in D-Wiesbaden, has contributed an article on the subject “Colour differences in concrete surfaces“ in OpusC magazine’s December 2011 issue, page 60-62, including many pictures and explanations. In 4 main categories Mr. Heeß mentions many aspects that need to be considered, if architectural concrete is produced and explains why it makes a difference. Those categories are:
Dyckerhoff Zement AG, like OpusC magazine, is cooperating with HEBAU in various associations and special projects. OpusC magazine is mainly read by architects and publishes those technical articles from time to time in order to improve the awareness of the special challenges during the production of architectural concrete. OpusC magazine can be ordered at www.opusc.com.
Loud speakers made of concrete, produced with several different HEBAU-products, including WETCAST-FormFluid HP, HYDROMIX-Fluid 50 and ARCON-Fluid+Plus. More information is available under www.klangkorper.net. 
Als HEBAU 1985 begann Anti-Graffiti-Schutzprodukte anzubieten, waren wir unserer Zeit vielleicht etwas voraus. Heute jedoch profitieren wir von unserer Erfahrung und der Tatsache, daß der Begriff der Nachhaltigkeit mittlerweile nicht nur im Zuge von Öko-Bilanzen, sondern von Bauherren und Investoren auch auf die Werthaltigkeit der Fassade und damit auch auf die langfristige Sauberkeit der Fassade/Wandflächen angewendet wird. Bestes Beispiel hierfür ist immer noch das ALEXA Einkaufcenter in Berlin, Alexanderplatz. Über die Farbe der Beton-Fertigteile kann man streiten, aber fest steht, daß das Gebäude frei von Graffitis ist, und das bei über 20.000 qm Fassadenfläche in Berlin, der „Stadt der Sprayer“. Daß das Objekt seinerzeit (2006) mit PROWALL gegen Graffitis prophylaktisch geschützt wurde, wurde vom Bauherrn publik gemacht und hält auch heute noch viele Schmierfinken ab. Und wenn‘s doch einer versucht ist das „Tag“ wenig später schon wieder weg.
