玄武岩纤维混凝土早期裂缝试验研究
Experimental Study on Early Crack of Basalt Fiber Reinforced Concrete
摘要
Abstract
In order to study the early cracking performance of basalt fiber reinforced concrete,basalt fiber concrete with different fiber length and basaltic concrete with different volume content were tested. The results show that the basalt fiber concrete has a significant decrease compared with ordinary concrete,and the early shrinkage crack of basalt fiber concrete decreases first and then increases slowly with the increase of fiber length,the best cracked fiber length is 18 mm. The early shrinkage crack decreases with the increase of fiber volume,and when the volume fraction reaches 0. 2%,the crack disappeares. With the increase of concrete strength,the anti-cracking index of fiber concrete is decreasing and the crack is shorter关键词
