Abstract In this paper, we successfully prepared a self-compacting, steel-fiber-reinforced lightweight aggregate concrete on the basis of self-compacting lightweight aggregate concrete and steel fibers reinforcements. A comparative study was carried out on the mechanical properties and durabilities (compressive strength, tensile strength, shrinkage, carbonization resistance, etc.) between the self-compacting steel-fiber-reinforced lightweight aggregate concrete and self-compacting concrete with ordinary aggregate. The function and mechanism of steel fiber in improving the damage of self-compacting lightweight aggregate concrete were discussed. The results showed that the addition of steel fibers lead to an increase of compressive strength and a significant rise of splitting tensile strength for lightweight aggregate concrete, as well as obvious improvements for both shrinkage and carbonation resistance. Compared with ordinary aggregate concrete, the emergence and propagation of primary cracks of the self-compacting steel-fiber-reinforced lightweight aggregate concrete can be effectively inhibited.

Key words： self-compacting steel-fiber-reinforced lightweight aggregate concrete mechanical property durability damage
