A platform for research: civil engineering, architecture and urbanism
The invention provides a preparation method of a desulfurized building gypsum-based composite cementing material which comprises the following components in parts by weight: 65-75 parts of desulfurized building gypsum, 15-20 parts of cement, 10-15 parts of fly ash, slaked lime accounting for 10-15% of the weight of the fly ash, 0.2-0.5 parts of a water reducing agent and 55-60 parts of water. Themethod actively responds to the national policy of energy conservation and waste utilization, can digest a large amount of original desulfurized gypsum, effectively solves the problem of recycling ofdesulfurized building gypsum, saves energy, utilizes waste, and is beneficial to environmental protection. According to the preparation method, the mechanical property and the water resistance of gypsum products are effectively improved, a high-quality green cementing material is provided for developing novel building materials, industrial by-product desulfurized building gypsum is used as a basematerial, and compared with a cement base material, the production cost can be greatly reduced, and the economic value potential is relatively great.
本发明提供了一种脱硫建筑石膏基复合胶凝材料的制备方法,按照重量组分,包括脱硫建筑石膏65‑75份、水泥15‑20份、粉煤灰10‑15份、熟石灰为粉煤灰重量的10%‑15%、减水剂0.2‑0.5份、水55‑60份。本发明积极响应国家节能利废政策,可以消化大量的原状脱硫石膏,有效解决了脱硫建筑石膏的资源化应用问题,节能利废,有益环保;有效提高石膏制品的力学性能和耐水性能,为开发新型建筑材料提供了一种优质的绿色胶凝材料,本发明利用工业副产物脱硫建筑石膏作为基材,与水泥基材相比可以大幅度降低生产成本,经济价值潜力较大。
