Experimental Study on Mechanical Properties of Steel Fiber Reinforced Lightweight Aggregate Concrete
In order to explore the optimization effect of mechanical properties of light aggregate concrete modified with different volume steel fi-ber content,the paper analyzed the change of properties of light aggregate concrete with steel fiber content ranging from 0 to 2.5%from the as-pects of impact resistance,bending toughness and compressive strength.The results show that adding steel fiber to lightweight aggregate con-crete can improve the compressive strength and optimize the structural failure pattern.The addition of steel fiber can improve the flexural strength of light aggregate concrete,solve the brittle problem of light aggregate concrete,and the improvement effect is enhanced with the in-crease of fiber content.The bending toughness and impact resistance of lightweight aggregate concrete are significantly enhanced after the addi-tion of steel fiber.
