PVA fiber reinforced cement-based composite material
The invention discloses a PVA fiber reinforced cement-based composite material, and relates to the technical field of fiber reinforced cement-based composite materials, wherein the PVA fiber reinforced cement-based composite material comprises the used main materials in percentage by mass: 18-23% of cement, 60-67% of fly ash, 10-15% of tailing sand, 1.7-2.1% of PVA fibers, 6-7.5% of a waterproof agent, 0.8-1.0% of sand glue, 13-15% of water, 0.35-0.6% of a water reducer, 0.03-0.05% of a thickening agent, and 0.03-0.05% of a defoaming agent. The fly ash replaces 2/3 of cement, so that the mixture has better cohesive force, the surface of the PVA fiber is coated with an oil agent, the tensile strain resistance of the PVA fiber can be improved, the connection characteristic of the matrix strength and the PVA fiber is improved, and a structural member is certainly endowed with higher durability.
本发明公开了一种PVA纤维增强水泥基复合材料，涉及纤维增强水泥基复合材料技术领域，其中所使用主料按照质量百分比包括水泥18‑23%、粉煤灰60‑67%、尾矿砂10‑15%、PVA纤维1.7‑2.1%、防水剂6‑7.5%、砂胶0.8‑1.0%、水13‑15%、减水剂0.35‑0.6%、增稠剂0.03‑0.05%、消泡剂0.03‑0.05%，本发明中的粉煤灰代替了水泥2/3的使用量，能够使拌合物具有更好的粘聚力，而PVA纤维表面涂覆有一种油剂，能够为其提高抗拉伸应变能力，使得基体强度与PVA纤维的连接特性得以提升，势必赋予结构构件更高的耐久性。
