CRC ductility - The potentials of our concrete

May 10, 2017  With the development of CRC, closely spaced reinforcement was combined with a high-strength matrix with stiff, strong fibres making it possible to achieve a behaviour like steel, but using a concrete – with the advantages that provided with regard to durability, fire resistance etc. The fibres provided “local” ductility
