中文摘要：

通过对超高韧性纤维增强水泥基复合材料制作的立方体试件、棱柱体试件,进行了抗压、抗折和I型断裂试验,研究了不同配合比下各组试块的抗压强度等力学指标与纤维掺量及基体材料强度的关系,研究了荷载与变形的关系、及不同切口高度试件的抗裂性能等。试验结果表明：合理的配合比及最佳PVA掺量能提高纤维增强水泥基复合材料的抗压强度、抗折强度以及抗裂韧度;研究了国产PVA纤维与进口PVA纤维的合理掺量,在相同力学指标的前提下,利用国内PVA纤维造价低的优势,可实现部分代替超高性能水泥基复合材料中的进口PVA纤维,从而达到这种复合材料国产化、本地化的目的。

英文摘要：

Through the compression,bending and type I fracture test of cube and prism specimens made with ECC, studied on compressive strength of mechanics and relationship between fiber content and matrix material strength, and the relationship between load and deformation, and the crack resistance of different cut height of different mixture rate.Experimental results showed that reasonable mixture rate and best PVA mixture could improve the compressive strength bending strength and fracture toughness of ECC; studied on reasonable amount of domestic and imported PVA fiber,with the same premise of the mechanical index and the low cost advantage of domestic PVA fiber to replace some imported PVA fiber,to achieve the goal of localization of this composites.
