Abstract
In order to compare and analyze the flexural and tensile properties of inorganic polymer lightweight aggregate concrete before and after adding steel fiber,the effects of different steel fiber volumes on the flexural and tensile strength and flexural toughness index of inorganic polymer lightweight aggregate concrete were studied in this study.The results show that compared with inorganic polymer lightweight aggregate concrete,the flexural tensile strength of laminated steel fiber concrete increases by 35.7%,45.2%and 54.7%,respectively,when the volume content of steel fiber is from 0.5%,1.0%to 1.5%.The flexural toughness of laminated steel fiber reinforced concrete is increased by 15.9,20.5 and 27.8 times respectively.The inorganic polymer lightweight aggregate concrete shows brittle failure,and the layered steel fiber inorganic polymer lightweight aggregate concrete has certain toughness.关键词
