Ultra-high performance concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses ultra-high performance concrete and a preparation method thereof. The ultra-high performance concrete comprises the following components in parts by weight: 18-27 parts of cement, 5-10 parts of fly ash, 2-8 parts of silica fume, 23-28 parts of river sand, 2-5 parts of composite industrial waste residues, 0.2-1.2 parts of a water reducing agent, 4-6 parts of water, 1-10 parts of steel fibers and 15-40 parts of stones, the composite industrial waste residue is composed of carbide slag, phosphorus slag and mineral slag according to the mass ratio of (0.1-0.5): 1: 1. The composite industrial waste residues are used as one of the raw materials to supplement the cementing material in the system, and the strength of the obtained ultra-high performance concrete is high. The recycling of industrial waste residue resources is realized, and the green and environment-friendly concept is met; the defect that the concrete strength is reduced due to addition of industrial waste residues is overcome, and the production cost is effectively reduced.
本申请涉及混凝土技术领域，具体公开了一种超高性能混凝土及其制备方法。一种超高性能混凝土，包括以下重量份的组分：水泥18‑27份、粉煤灰5‑10份、硅灰2‑8份、河砂23‑28份、复合工业废渣2‑5份、减水剂0.2‑1.2份、水4‑6份、钢纤维1‑10份、石子15‑40份；复合工业废渣由电石渣、磷渣和矿渣按照质量比（0.1‑0.5）：1:1组成。本申请以复合工业废渣作为原料之一补充体系内的胶凝材料，所得到的超高性能混凝土的强度较高。实现了工业废渣资源的再利用，契合绿色环保理念；并且克服了添加工业废渣导致混凝土强度下降的缺陷，有效降低了生产成本。
