Low-shrinkage environment-friendly economical high-ductility cement-based composite material and preparation method thereof
The invention relates to the technical field of building materials, and discloses a low-shrinkage environment-friendly economical high-ductility cement-based composite material and a preparation method thereof. The low-shrinkage environment-friendly economical high-ductility cement-based composite material is prepared from the following raw materials in parts by mass: 307 to 367 parts of cement, 756 to 816 parts of fly ash, 319 to 359 parts of water, 375 to 435 parts of recycled fine aggregate, 24.8 to 26.8 parts of polyvinyl alcohol fiber and 3 to 3.8 parts of a water reducing agent, according to the invention, the industrial waste fly ash is used as a mineral admixture to partially replace the cement, and the recycled fine aggregate obtained by crushing and screening the building solid waste is used to completely replace the quartz sand, so that the prepared high-ductility cement-based composite material not only has the performance advantages of high strength, high toughness, low shrinkage and the like, but also reduces the material cost, realizes recycling of waste materials, and is beneficial to environmental protection. And energy consumption and carbon emission are reduced.
本发明涉及建筑材料技术领域，公开了一种低收缩环保经济型高延性水泥基复合材料及其制备方法。这种低收缩环保经济型高延性水泥基复合材料由以下质量份数的原料制备而成：水泥307～367份，粉煤灰756～816份，水319～359份，再生细骨料375～435份，聚乙烯醇纤维24.8～26.8份，减水剂3～3.8份；本发明使用工业废料粉煤灰作为矿物掺和料对水泥进行部分取代，采用建筑固废破碎筛分而得的再生细骨料全取代石英砂，制得的高延性水泥基复合材料不仅具有高强度、高韧性、低收缩等性能优势，还降低了材料造价，实现了废材再利用，减少了能源消耗与碳排放。
