| 摘 要： | 采用改进的钢纤维混凝土劈拉试验方法,研究了钢纤维混凝土、聚丙烯腈纤维混凝土及混杂纤维混凝土的劈拉强度及劈拉韧性,结果表明:钢纤维、聚丙烯腈纤维均能够提高混凝土的极限劈拉强度,其中钢纤维明显提高混凝土的劈拉韧性;钢一聚丙烯腈纤维组合使用对混凝土的劈拉强度及韧性具有正混杂效应.通过对试验结果的分析,推荐了钢-聚丙烯腈纤维混杂掺入混凝土时的一种较优混杂比例.

| Abstract: | Based on the idea of improved test method of splitting of steel fiber reinforced concrete,the effect of steel fiber ,polyacrylonitrile fiber and hybrid fibers on splitting strength and splitting toughness of concrete is studied in the paper.The results show that both steel fiber and polyacrylonitrile fiber have positive effet on the splitting strength of concrete,while steel fiber also helps to improve the splitting toughness of concrete. The steel- polyacrylonitrile fiber has synergy on the splitting strength and toughness of concrete.According to the analysis of the test results,an optimal hybrid ratio of steel- polyacrylonitrile fiber was proposed. |
