摘　　要：现代建筑业发展过程中 ,涌现出一系列的新型建筑材料。其中在传统混凝土中掺加纤维 ,能使混凝土综合性能尤其是防裂性能有大幅度的提高。本文通过改变加入纤维的品种、长度、含量 ,研究了各项因素对水泥混凝土防裂性能的影响。结果表明 ,适当控制纤维长度、含量 ,改性异形 PP。With the developing of modern architecture, a series of new construction materials come forth. General performance, especially anti crack performance of the cement can be improved obviously by adding polymer fiber to it. In this paper, anti crack performance of cement is studied when different fibers with different length and weight percent are added. Results show that if fiber length and weight percent is properly controlled, cement anti crack performance can be improved enormously by modified profiled PP of fiber.
