Ultrahigh-performance iron tailing sand concrete and preparation method thereof
The invention provides ultrahigh-performance iron tailing sand concrete and a preparation method thereof, and relates to the technical field of concrete production and application. The ultrahigh-performance iron tailing sand concrete provided by the invention is prepared from the following preparation raw materials in parts by mass: 600 to 660 parts of cement, 140 to 165 parts of silica fume, 90 to 110 parts of fly ash, 140 to 165 parts of slag powder, 1000 to 1100 parts of iron tailing sand, 8 to 11 parts of a water reducing agent, 165 to 181.5 parts of water and 104 to 180 parts of fibers, the fibers comprise steel fibers and polyformaldehyde fibers. The iron tailing sand is used as the aggregate of the ultra-high performance concrete, so that the production cost of natural sand and ground quartz sand can be remarkably reduced, the exploitation of the natural sand and the quartz sand is reduced, the damage to the natural environment is reduced, and the utilization rate of the solid waste iron tailing sand is increased; meanwhile, the polyformaldehyde fiber is used for replacing part of steel fiber, so that the production cost is lower.
本发明提供了一种超高性能铁尾矿砂混凝土及其制备方法，涉及混凝土生产应用技术领域。本发明提供的超高性能铁尾矿砂混凝土，按质量份数计，包括以下制备原料：水泥600～660份、硅灰140～165份、粉煤灰90～110份、矿渣粉140～165份、铁尾矿砂1000～1100份、减水剂8～11份、水165～181.5份和纤维104～180份；所述纤维包括钢纤维和聚甲醛纤维。本发明中铁尾矿砂作为超高性能混凝土的骨料，可显著降低使用天然砂和磨细石英砂的生产成本，减少对天然砂和石英砂的开采，以及减少对自然环境的破坏，提高固体废弃物铁尾矿砂的利用率；同时本发明中使用聚甲醛纤维替代部分钢纤维，生产成本更低。
