Space Age Concrete That May Sub For Steel

A new concrete with 20 times the compressive and tensile strength of the best now available may lead to better construction and design. Developed by French construction company Bouygues, Reinforced Powder Concrete (RPC) gets its strength from fine steel wires, or microfibers, a fraction of a millimeter thick. They make the use of conventional reinforcement bars unnecessary. RPC's brittleness is only 1 100 that of conventional concrete.
