PVA纤维对再生粗集料透水混凝土性能的影响研究
Study on Affection of the PVA Fiber on Recycled Coarse Aggregate to Porous Concrete Performance
透水混凝土是具有拱架结构的多孔混凝土。本试验采用高质化处理过的再生粗集料质量替换普通粗集料30%，再添加（水泥质量的0.0%、0.5%、0.1%、1.5%）PVA纤维，进行了PVA纤维对多孔混凝土强度、有效孔隙率、透水系数的影响分析，并讨论了多孔混凝土的干温缩特性，为再生粗集料多孔混凝土的设计与应用提供了依据。
Pervious concrete is one kind of porous concrete which has skeleton structure. In this test the recycled coarse aggregate replacement ratio is 30%, by using recycled coarse aggregate which through high quality processing replaces ordinary coarse aggregate and adding PVA fiber (the mass of PVA fiber is 0%, 0.5%, 1.0% and 1.5% of the cement, respectively), the influence of PVA fiber on the strength, effective porosity and permeable coefficient of porous concrete are studied. Besides, the dry shrinkage property and temperature contraction property of porous concrete are discussed. The results can provide the basis for the design and application of the recycled coarse aggregate porous concrete.
