| Abstract: | In order to solve the problem of contraction-caused cracks in high-performance concrete,a study is made of the effects of different kinds of polypropylene fibers,and different amounts of them used on the anti-cracking performance of concrete in the paper,the result of which shows that the correct choice of the right kinds of polypropylene fibers,with the right amounts of 0.6-1.0 kg/m3 used,can not only ensure the workability,compressive strength and durability of the concrete but also effectively improve the anti-cracking property of high performance concrete. |
