Almost no other material manages to carry such contradictory associations. Stigmatised on the one hand, celebrated on the other, it evokes highly diverse reactions. The word 'concrete' was used for the first time in 1750 by Bernard Forêst de Bélidor as a description for a mortar, in his book 'Architecture hydraulique'. The first ferroconcrete structures were built around 1900. Today, reinforced concrete is Germany's most important building material, with over 100 million cubic metres of it used every year. Its potential seems almost inexhaustible and continual innovations in how it's applied make it a valuable material for new architecture concepts. What follows is a look at concrete, related new technologies and a selection of interesting projects that have embraced these.
