摘要
通过室内试验,研究了杜拉纤维水泥混凝土的工作性、抗压强度、抗劈拉强度、收缩性能,并与普通水泥混凝土进行了对比分析。研究发现,在混凝土中掺加杜拉纤维对混凝土的劈拉强度有很大的提高,提高了约14.6%,对混凝土的早期抗收缩性能也有显著的提高。研究结果表明,杜拉纤维增强水泥混凝土具有许多优于普通水泥混凝土的优良特性。
This paper carded out a large number of laboratory tests to study the workability,compressive strength, split tensile strength,perforo mance of shrinkage of Durafiber Reinforced Cement Concrete,and its performance was compared with normal cement concrete. It is pointed that Durafibers added in concrete improve-its split tensile strength more, approximately 14.6%, and its shrinkage-resistance increasing obviously. The results indicate that Durafiber Reinforced Cement Concrete has many excellent advantages over normal cement concrete.
