Steel fiber reinforced concrete (SFRC) has the same mixing, operation construction performance as ordinary concrete. The fiber will form a ball in the concrete is evenly distributed. It can be produced in commercial concrete mixing plant can be used for pumping construction. The early slump loss of milling steel fiber reinforced concrete is large, 32% in 30 minutes 42% in 2 hours. The workability of SFRC is better than that of ordinary concrete with the same slump. Steel fiber reinforced concrete has good material properties. Compared with ordinary concrete, its compressive strength is increased by 2-20%; its flexural strength is increased by 20-50%; its splitting tensile strength is increased by 20-40%; its wear resistance is increased by about 40%. Its physical mechanical properties can fully meet the technical requirements of urban road engineering, manhole cover other supporting components. The rough clean surface of steel fiber can be firmly combined with cement paste in concrete, which is the fundamental reason for milling steel fiber to improve various properties of concrete.
