cool concrete


Lafarge, a big French cement company, invited journalists to Lyon to see its new concrete R&D center. These guys are demonstrating Extensia, a concrete that can be used to pour slabs of 400 square meters without joints, compared to only 25 square meters for ordinary concrete. That's supposed to make the job easier and faster, and reduce cracking in the concrete. The floor of the R&D center was made with Extensia concrete.
