Sulfate-resistant low-alkali Portland cement and preparation method thereof
The invention relates to the technical field of cement manufacturing, in particular to sulfate-resistant low-alkali Portland cement and a preparation method thereof, and the sulfate-resistant low-alkali Portland cement comprises the following raw materials by mass: 12-13% of ceramic soil residue; 3.5%-4% of copper slag; 3%-4% of silicon powder; and 80%-82% of carbide slag. The raw materials are dried, ground and calcined to obtain the sulfate-resistant low-alkali Portland cement. According to the sulfate-resistant low-alkali Portland cement and the preparation method thereof, effective utilization of the carbide slag is achieved, and a large number of resources are saved. The carbide slag is mainly composed of calcium hydroxide, does not produce CO2 during calcination, is easy to calcine, has low energy consumption and low production cost, avoids resource waste and environmental pollution, and is low-carbon and environment-friendly. The produced clinker and cement are high in strength and stable in quality, and the best effect is achieved.
本发明涉及水泥制造技术领域，具体涉及一种抗硫酸盐低碱硅酸盐水泥及其制备方法，包括下述质量分数的原材料：陶瓷土渣12%‑13%；铜渣3.5%‑4%；硅粉3%‑4%；电石渣80%‑82%；上述原材料经烘干、粉磨并煅烧制得，本发明的一种抗硫酸盐低碱硅酸盐水泥及其制备方法，实现了电石渣有效利用，节省了大量资源；电石渣主要成分为氢氧化钙，煅烧不产生CO2，且易于煅烧，能耗低，生产成本较低，避免了造成资源浪费和环境污染，低碳环保；所生产的熟料及水泥强度高，质量稳定，达到最佳效果。
