摘要
对聚丙烯腈纤维增强水泥砂浆和混凝土的早期阻裂性能进行了试验研究。试验证明 ,聚丙烯腈纤维对改善混凝土和砂浆的早期抗裂性有良好的效果 。
Tests of restrained initial shrinkage properties with plain and polyacrylonitrile fiber reinforced concrete and mortar are introduced in this paper. The results of tests show that the polyacrylonitrile fiber reinforced concrete and mortar have good crack inhibitors of early period. The curing condition has significantly effects on the early crack inhibitors
