Experimental research on performance of steel fiber reinforced self-compacting concrete

In order to fully exert the high strength and high toughness of steel fiber concrete and the good construction performance of self-compacting concrete, a high performance steel fiber reinforced self-compacting concrete is produced based on the optimal selection of raw materials and the reasonable design for mix proportion. In this paper, experimental study on mechanical property and research results on workability of the steel fiber reinforced self-compacting concrete are mainly introduced. The results show that steel fiber reinforced self-compacting concrete has excellent mechanical properties, good dispersible uniformity of steel fiber, which is suitable for the section of densely-packed reinforcement, small workspace and other complex shapes.
