Desulfurized gypsum and fly ash cementing material formula
The invention provides a desulfurized gypsum and fly ash cementing material formula. The desulfurized gypsum and fly ash cementing material formula comprises, by mass, 16-20% of fly ash, 16-20% of desulfurized gypsum, 26-34% of cement, 18-23% of water, 11-13% of sands and 1% of quick ime. Adopted desulfurized gypsum mainly comes from a byproduct desulfurized gypsum produced by a limestone (lime)-gypsum wet desulphurization process in a large-unit coal-fired power plant, is simple and convenient to manufacture, and only needs to uniformly stir fly ash, desulfurized gypsum, cement, water, sand and quicklime in proportion in advance. Compared with common concrete, the cementing material of the invention has the characteristics of production cost reduction, light weight and heat preservation.The formula solves the problem of treatment of desulfurized gypsum and fly ash, solves the problem of environmental pollution caused by solid wastes, protects cultivated land resources, realizes resource utilization of the solid wastes, and meets the requirement of building energy conservation.
本发明的提供一种脱硫石膏粉煤灰胶结材配方，组分和质量百分含量为：粉煤灰16‑20％、脱硫石膏16‑20％、水泥26‑34％、水18‑23％、沙子11‑13％、生石灰1％。所采用的脱硫石膏主要来源于大机组燃煤电厂采用石灰石(石灰)‑石膏湿法脱硫工艺产生的副产物脱硫石膏，制作简便，仅需要事先按比例将粉煤灰、脱硫石膏、水泥、水、沙子、生石灰搅拌均匀即可。与普通混凝土相比，降低了生产成本，并具有轻质保温的特点。解决了脱硫石膏及粉煤灰的处理难题，解决固体废弃物所造成环境污染问题，保护了耕地资源，实现了固体废弃物的资源化利用，并满足了建筑节能的需要。
