摘要
针对高性能混凝土的收缩开裂问题,试验研究了聚丙烯纤维品种及掺量对混凝土抗裂性的影响。结果表明:选用适宜品种的聚丙烯纤维,掺量在0.6～1.0kg/m3之间,在不影响混凝土的和易性、抗压强度和耐久性的基础之上,可有效改善混凝土的抗裂性。
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.
