Abstract
The article studies the impact of steel fiber on the performance of lightweight aggregate concrete,including compressive strength, flexural strength, modulus of elasticity and impact toughness. The experimental studies show that steel fiber has little effect on the compressive strength of lightweight aggregate concrete, however, it can improve the pattern obviously. With the increasing of steel fiber content, the flexural strength and impact toughness of concrete increases. With the increasing of steel fiber content ,the elastic modulus of concrete also increases. The studies of this paper provide a certain technical references with the future research of steel fiber reinforced lightweight aggregate concrete.
