Portland cement clinker and preparation method thereof
The invention discloses Portland cement clinker and a preparation method thereof, and belongs to the field of building material preparation. The Portland cement clinker comprises the following components by weight percentage: 52%-58% of limestone, 23%-26% of coal gangue, 8%-12% of iron tailings, 5%-10% of fly ash, 1.2%-1.8% of fluorgypsum and 0.8%-1.2% of calcium fluoride. Limestone is used as a calcareous raw material, coal gangue is used as a silicon-aluminum raw material, iron tailings and fly ash are used as correction materials, fluorgypsum and calcium chloride are used as a mineralizer,a large amount of solid waste can be consumed to produce the Portland cement clinker, and the mineralizer is introduced at the same time to improve the burnability of raw materials and improve the quality and yield of the clinker. According to the method, waste can be turned into wealth, accumulation of a large amount of solid waste is effectively reduced, the raw material supply problem is relieved, and meanwhile the cost is saved.
本发明公开了一种硅酸盐水泥熟料及其制备方法，属于建筑材料制备领域。包括如下重量百分比的下列组分：52%‑58%石灰石、23%‑26%煤矸石、8%‑12%铁尾矿、5%‑10%粉煤灰、1.2%‑1.8%氟石膏、0.8%‑1.2%氟化钙。以石灰石为钙质原料、煤矸石为硅铝质原料、铁尾矿和粉煤灰作为矫正料，氟石膏和氯化钙作为矿化剂，能够大量消耗固废生产硅酸盐水泥熟料，同时引入矿化剂，改善生料易烧性，提高熟料质量和产量。本发明不仅可以变废为宝，而且有效减少大量固废堆积，缓解原料的供给问题，同时节约成本。
