摘　　要：探讨了秸秆纤维对低碱水泥基材料阻裂性能的影响,结果表明,基准低碱水泥砂浆的塑性收缩裂缝的开裂权重值为37.5cm,随着秸秆纤维的掺入其裂缝明显减少,当掺入0.2%时塑性收缩的裂缝减少了96%,当超过0.5%时,砂浆基本不产生裂缝,说明秸秆纤维的掺入对低碱水泥砂浆具有很好的阻裂效果。This paper discusses the effect of straw fibers on low alkali cement based materials properties of crack resistance. The results show that the benchmark mortar for cracks in the plastic shrink 37.5 cm, but with the introduction of straw fiber, significantly reducing its cracks .When the introduction of 0.2 percent, plastic shrinkage cracks on the reduction of 96 percent, when more than 0.5%, mortar basically do not have cracks, a description of the incorporation of straw fiber cement mortar has good resistance Cracked effect.

关 键 词：秸秆纤维 水泥基复合材料 塑性开裂 阻裂
