| 摘 要： | PVA(聚乙烯醇)纤维增强水泥基复合材料(PVA-ECC)是一种采用水泥、矿物掺合料、水、粒径小于5mm的细骨料与PVA纤维拌和而成的水泥基复合材料。文中阐述了PVA纤维增强水泥基复合材料的基本性能,与普通混凝土相比,其抗压试验中达到峰值荷载后承载力下降缓慢,抗拉和弯曲试验中均显示出应变硬化特性,且具有更好的抗剪承载力和抗剪切变形的能力。纤维增强水泥基复合材料具有优异的延性和耐久性,已成功应用于实际工程。

| Abstract: | PVA engineered cementitious composites （PVA-ECC） is a cement-based composite materials made of cement, mineral admixture, water, fine aggregate particle size less than 5 mm mixing with PYA fiber. This paper summarizes the basic performance of PVA-ECC. Compared with general concrete, the capacity after the peak load test decreased slowly in the compression, and tensile and bending tests show strain hardening characteristics, and it has better shear strength shear deformation. ECC have excellent ductility and durability, and it has been successfully applied in practical engineering. |
