摘　　要：绿色水泥基复合材料是一种可持续发展的新型建筑材料,通过对其抗压性能和抗折强度的试验研究,分析了纤维体积掺量和养护龄期对其力学性能的影响。结果表明:PVA纤维体积掺量在0%~1%时,纤维的桥联作用可提高绿色水泥基复合材料的抗压强度,改善其抗压韧性;养护龄期和纤维掺量对绿色水泥基复合材料的抗折强度的影响均较为显著。研究结论为绿色水泥基复合材料的制备和工程应用提供了参考。Green cementitious composites are a new building material of sustainable development.Through the experimental study on its compressive properties and flexural strength,the influence of fiber volume content and curing age on its mechanical properties is analyzed.The results show that when the volume of PVA fiber is in the range of 0%to 1%,the bridging effect of fiber can improve the compressive strength and compressive toughness of cement-based materials.Curing age and fiber content have significant effects on the flexural strength of green cementitious composites.The research conclusions can provide a reference for the preparation and engineering application of green cementitious composites.
