Innovation: CPC concrete slabs for the construction industry

CPC (carbon prestressed) concrete slabs are based on a new technology that evolved from a long-term research project conducted by ZHAW and the company Silidur AG, in Andelfingen, Switzerland. The advantages of CPC slabs enable their numerous applications; first l projects in Switzerland have already been executed.

CPC slabs are reinforced with thin prestressed carbon strands. The very high tensile strength of carbon and the fact that carbon does not corrode enable the manufacture of thin loadbearing slabs. The previously required concrete cover of 3 to 4 cm to the reinforcement, as required for...
