Flexural Impact Behavior of Basalt Fiber Concrete

DENG Zong-cai,XUE Hui-qing (School of Architecture and Civil Engineering,Beijing University of Technology,Beijing 100022,China)  
In order to research the effect of basalt fiber on the flexural impact behavior of concrete,the flexural impact experiments on basalt fiber concrete and plain concretes were carried out systematically.The results of flexural impact experiment of beams indicate that the initial-crack impact number of basalt fiber concrete B3(the fiber quality content is 2.8 kg·m-3) improves 62% and 95% from B2(the fiber quality content is 2.1 kg·m-3) and B1(the fiber quality content is 1.7 kg·m-3) respectively,B2 improves 21% from B1;the failure impact number of basalt fiber concrete B3 improves 59% and 90% from B2 and B1 respectively,B2 improves 19% from B1;when fiber quality content improved from B2 to B3,the flexural impact behavior of fiber reinforced concrete is improved significantly.Basalt fibers can remarkably improve the flexural impact behavior of concrete.
