Low-carbon slag cement and preparation method thereof
The invention provides low-carbon slag cement and a preparation method thereof. The low-carbon slag cement is prepared from the following components in parts by weight: 70-90 parts of mineral powder, 5-25 parts of Portland cement clinker, 5-15 parts of iron tailings, 1-5 parts of desulfurized gypsum, 0.0005-0.002 part of a vertical mill grinding-aiding component, 0.0005-0.002 part of a grinding-aiding enhancing component and 0.0005-0.002 part of a dispersing component, compared with the prior art, the low-carbon cement with low clinker dosage and good performance is obtained by reasonably matching and designing the type, dosage and particle size of the cementing material and optimizing the initial slurry structure, so that the hydration processes of all the materials are matched with one another. According to the method, a small amount of clinker fine powder is used for exciting fine mineral powder particles, so that the problem of high water demand caused by rapid hydration of a large amount of clinker fine particles is avoided, hydration of the fine mineral powder particles can be fully excited, and the early strength of the low-carbon cement is ensured. In addition, a large amount of waste silicon powder, slag and iron tailings are reasonably utilized, and low carbon and environmental protection are achieved.
本发明提供了一种低碳矿渣水泥及其制备方法，矿粉70‑90份、硅酸盐水泥熟料5‑25份、铁尾矿5‑15份、脱硫石膏1‑5份、立磨助磨组份0.0005‑0.002份、助磨增强组份0.0005‑0.002份、分散组份0.0005‑0.002份；与现有技术相比，本发明对胶凝材料的种类、用量和颗粒粒度进行合理的搭配设计，优化初始浆体结构，使各材料水化进程相互匹配，得到熟料用量低，性能好的低碳水泥。本发明用少量的熟料细粉激发细矿粉颗粒，即避免大量熟料细颗粒快速水化带来的需水量高的问题，又能充分激发细矿渣粉颗粒的水化，保证低碳水泥的早期强度。且，本发明大量合理利用废硅粉、矿渣和铁尾矿，低碳环保。
