Abstract
In order to study the effect of basalt fiber on the early performance of hydraulic concrete,this paper studied the effect of basalt fiber on the early performance of hydraulic concrete,and analyzed the mechanism of basalt fiber by SEM test.The results show that doping basalt fi-ber can significantly improve the performance of concrete.When the curing age is 28 days,the compressive strength,flexural strength and shear strength of basalt fiber reinforced concrete are increased by 8.09%,17.21%and 12.10%respectively compared with ordinary con-crete.Combined with the SEM observation results,it is shown that basalt fiber has good bonding property with cement,and forms a disorderly and uniform three-dimensional network structure in the internal pores of concrete,improving the microstructure of concrete,enhancing the con-crete compactness,and thus improving the bonding property of concrete mechanical properties.关键词
