Abstract:

Study on the effect of liquefaction mechanism on the performance of ECC, adding rubber powder mesh size effect on the performance of ECC, respectively, to 40 mesh, 60 mesh, 80 mesh and 100 orders at the same content of rubber powder and 40 mesh in different dosage on ECC compressive strength, flexural toughness was analyzed, results show that: the use of the mechanism of liquefaction of mixing rubber powder in cement based materials, with the increase of ECC number increased ductility, at the same time reduce the compressive strength is larger, rubber powder content in 12%, the comprehensive effect is ideal. The needle for fiber reinforced cement based materials and meticulous research component, has broad prospects in the repair of future building early warning and lane.
