Low-clinker cementing material as well as preparation method and application thereof
The invention provides a low-clinker cementing material as well as a preparation method and application thereof, the cementing material is formed by mixing various raw materials, and the various raw materials comprise the following components in percentage by mass on a dry basis: 30%-50% of calcined high laterite tailings, 10%-20% of dolomite, 35%-45% of Portland cement clinker and 4%-6% of gypsum. The prepared low-clinker cementing material can be used for preparing concrete according to the mixing proportion of conventional C30-grade concrete, the mechanical property of the prepared concrete can reach the C30 grade, but the content of Portland cement clinker is lower, and industrial carbon emission reduction of cement is facilitated; the raw materials are green and low-carbon, have extremely high pozzolanic activity in a cementing material system, and can improve the mechanical properties and durability of the cementing material; according to the method, efficient utilization of solid waste and bulk natural easily-obtained minerals is achieved, CO2 is not directly discharged in the processing process, and the method is green, low-carbon, environmentally friendly and remarkable in economic effect.
本发明提供了一种低熟料胶凝材料及其制备方法与应用，所述胶凝材料由多种原料混合而成，所述多种原料按物料干基质量百分比计，包括30％～50％的煅烧高铁矾土尾矿、10％～20％的白云石、35％～45％的硅酸盐水泥熟料以及4％～6％的石膏。本发明制得的低熟料胶凝材料可按照常规C30等级混凝土配合比制备混凝土，所制备混凝土力学性能均可达到C30等级，但硅酸盐水泥熟料的含量更低，有助于水泥工业碳减排；本发明原料绿色低碳，在胶凝材料体系中具有极高的火山灰活性，能够提高胶凝材料力学性能和耐久性；本发明实现了固废和大宗天然易得矿物的高效利用，加工过程不直接排放CO2，绿色低碳、环保，经济效果显著。
