摘要
对纤维水泥砂浆的力学性能分析表明,加入聚丙烯纤维后,(1)砂浆的体积密实,抗压强度有一定提高;(2)砂浆的韧性增加,脆性降低,提高了砂浆的抗拉强度;(3)对抵抗砂浆收缩有明显作用,尤其对早期砂浆的收缩有明显的改善效果;(4)经多次冻融循环,质量损失和强度损失都明显降低。
The analysis shows that after admixed with polypropylene fiber, the mortar has a high density and its compressive strength has been improved to certain extent; and toughness increases and brittleness decreases while tensile strength enhances; meanwhile, it can resist the shrinkage, in particular, that of the early age obviously; and after freezing-thawing circulations, quality loss and strength loss reduce apparently.
