High-performance cement concrete and preparation method thereof
The invention belongs to the technical field of building materials, and relates to high-performance cement concrete and a preparation method thereof. The raw materials comprise cement, a superfine admixture, quartz sand, aggregate, a fiber composition, a water reducing agent, a silane emulsion and water. The density of the cement concrete is improved through gradient compounding of the quartz sand and the aggregate, the mechanical property of the cement concrete is improved by combining the coal ash and the silica fume in the superfine admixture and the steel fibers and the polyvinyl alcohol fibers in the fiber composition, and the problem that the mechanical property is remarkably reduced after the silane emulsion is added is solved.
本发明属于建筑材料技术领域，涉及一种高性能的水泥混凝土及其制备方法。原料包括：水泥、超细掺合料、石英砂、骨料、纤维组合物、减水剂、硅烷乳液和水。本发明通过石英砂和骨料的梯度复配提升了水泥混凝土的密度，结合超细掺合料中的粉煤灰和硅灰以及纤维组合物中的钢纤维和聚乙烯醇纤维提升了水泥混凝土的力学性能，解决了加入硅烷乳液后导致的力学性能显著下降的问题。
