Study on mechanical properties of basalt fiber reinforced coral concrete under loading

Abstract

Basalt fiber and cement are easy to disperse concrete and mortar, so basalt fiber reinforced concrete plays the role of reinforcement, crack prevention and crack resistance. The basalt fiber has good ductility and corrosion resistance, which can replace the traditional concrete and is widely used in construction engineering. In order to improve the strength of coral concrete in marine engineering, the compressive strength and creep properties of coral concrete mixed with basalt fiber were tested, and the creep prediction model suitable for coral concrete was established. The experimental results show that the effect of basalt fiber on the compressive strength of reinforced concrete is not significant; The creep behavior of basalt fiber reinforced coral concrete is higher than that of ordinary concrete; By modifying the existing creep model, a creep prediction model suitable for coral concrete is established. These experimental results can provide a reference for the design of coral concrete structures in ocean engineering.
