摘　　要：对不同掺量的聚丙烯腈纤维砂浆的抗裂性能进行了研究,并分析了抗裂作用机理。结果表明,砂浆中纤维掺量为0.5 kg/m^3、0.8 kg/m^3和1.0 kg/m^3时,裂缝可分别减少32.7%、60.5%和94.8%。The crack redistance of different content of Polyacrylonitrile Fiber Reinforced Mortar has been studied and the mechanism of anti-cracking has been analyzed.The results indicate that when content percentage of fiber is 0.5 kg/m^3,0.8 kg/m^3,and 1.0 kg/m^3,crack of mortar can reduce 32.7%,60.5%and 94.8%.
