钢丝网混杂纤维增强水泥砂浆拉伸试验研究

摘要

The direct tensile behaviour of steel-polypropylene hybrid fiber reinforced ferrocement with different mix ratios were tested in this paper.Experimental results showed that the ultimate strength of steel-polypropylene hybrid fiber reinforced ferrocement with 0.5% volume fractions of steel fiber and 1.0% volume fractions of polypropylene fiber increased by 15%,and the toughness also improved;Compared with other mix ratios,this mix ratio had best effect on the tensile property of ferrocement.Furthermore,the mechanical property of steel-polypropylene hybrid fiber reinforced ferrocement was analyzed in the paper.%对不同配合比的钢丝网钢-聚丙烯混杂纤维增强水泥砂浆进行拉伸试验,研究表明：体积分数为0.5%钢纤维与1.0%聚丙烯纤维混杂的钢丝网钢-聚丙烯混杂纤维增强水泥砂浆极限强度提高了15%,韧性也有大幅度的提升;比较可知该组配合比拉伸性能效果最佳.同时对拉伸试验过程进行了受力分析.
