Experimental Research on Crazing-resistance of Inclined Section of Basalt Fiber Reinforced Concrete Beams Wei Chena, Xiangpeng Lib, Tingting Chenc, Xiaoyang Wangd, Chaochao Mae College of Civil Engineering, Sichuan Agricultural University, Dujiangyan, Sichuan, 611830, China achenweijiegou@163.com, bsharelee33@Gmail.com, c513723233@qq.com, d513723233@qq.com Keywords: Basalt fiber; Reinforced concrete beam; Cracking load; Diagonal crack width Abstract.
Fiber concrete is one of the most important research field of concrete character modified, which are many different kinds of fiber concrete used engineering, as the development of four high technology which the country encourages, which have listed in the national 863 program, Torch program its excellent mechanics performance, durability, and green pollution-free production process.
With basalt fiber, matrix played the crack resistance of concrete and strengthening effect, the damage form of improved the brittleness of concrete is easy to crack, which can be widely used in buildings, high strength, flame retardant, tunnel and underground engineering.
