Mineral admixture suitable for phosphorus-based cementing material as well as preparation method and application of mineral admixture
The invention provides a mineral admixture suitable for a phosphorus-based cementing material as well as a preparation method and application of the mineral admixture. The mineral admixture is prepared by taking carbide slag and Portland cement clinker as raw materials, spraying a small amount of additive on the surface of the raw materials, carrying out ball milling on the uniformly mixed materials in a ball mill for 25-30 minutes, and sieving with a 200-mesh sieve. The mineral admixture prepared by the invention can effectively solidify soluble phosphorus in the phosphorus-based cementing material, stimulate the activity of phosphorus slag and generate C-S-H gel and AFt in a hydration process, so that the mechanical property and water resistance of the phosphorus-based cementing material are remarkably improved. In addition, the mineral admixture takes the carbide slag as a main raw material, and the preparation method is simple, low in energy consumption and favorable for promoting the utilization of solid wastes in the phosphating industry in engineering.
本发明提供一种适用于磷基胶凝材料的矿物掺合料及其制备方法和应用。本发明的矿物掺合料以电石渣和硅酸盐水泥熟料为原材料，在其表面喷洒少量外加剂，将混合均匀的物料在球磨机中球磨25‑30min，过200目筛后制备而成。本发明制备的矿物掺合料可以有效固化磷基胶凝材料中的可溶性磷，激发磷矿渣的活性，在水化过程中生成C‑S‑H凝胶和AFt，使磷基胶凝材料的力学性能和耐水性能得到显著提升。此外，该矿物掺合料以电石渣为主要原材料，且其制备方法简单、能耗低，有助于推进磷化工业固体废弃物在工程中的利用。
