Abstract
In order to improve the mechanical properties of self-compacting concrete,self-compacting concrete was modified with steel fiber and polypropylene fiber,and the effects of steel fiber and polypropylene fiber on the working performance,compressive strength,tensile strength and flexural strength of SCC were analyzed.The test results show that doped fiber can reduce the fluidity of concrete,improve the anti-segregation of concrete,and doped steel fiber has a great effect on the performance of SCC.The doped fiber has little effect on the compres-sive strength of concrete,but can significantly improve the tensile and flexural strength of concrete.The specimens with 0.6%steel fiber con-tent have the best performance,and the compressive strength,tensile strength and strength are increased by 4.22%,32.79%and 33.81%,respectively,compared with the specimens in the reference group.关键词
