High-strength polyvinyl alcohol fiber reinforced cement-based composite material as well as preparation method and application thereof
The invention relates to the technical field of building materials, in particular to a high-strength polyvinyl alcohol fiber reinforced cement-based composite material and a preparation method and application thereof. The high-strength polyvinyl alcohol fiber reinforced cement-based composite material is prepared from the following raw materials in parts by weight: 100-130 parts of superfine Portland cement, 325-350 parts of an active mineral admixture, 215-230 parts of an inorganic admixture, 1-2 parts of a defoaming agent, 2-2.3 parts of a water reducing agent, 45-60 parts of water and 3-5 parts of polyvinyl alcohol fiber. According to the invention, a PVA-ECC material is applied to the ultra-high performance concrete to prepare the composite material, and the composite material is applied to preparation of an anti-seismic structure, a large-deformation structure and a composite structure.
本发明涉及建筑材料技术领域，具体来说是高强度聚乙烯醇纤维增强水泥基复合材料及其制备方法和应用，由如下重量份数的原料制成：超细硅酸盐水泥100‑130份；活性矿物掺合料325‑350份；无机掺合料215‑230份；消泡剂1‑2份；减水剂2‑2.3份；水45‑60份；聚乙烯醇纤维3‑5份。本发明将PVA‑ECC材料应用于超高性能混凝土中制得复合材料，并将此复合材料应用于制备抗震结构、大变型结构和复合结构中。
