摘　　要：介绍了资源化利用脱硫石膏生产高强高精度砌块的原料选择、工艺流程、产品质量、改进措施、工程应用、经济分析。高强高精度砌块通过合理掺入一定比例的新型矿化剂后强度高、耐水性好、不空鼓、不开裂、无返霜返碱现象。砌块的榫卯结构合理、几何尺寸精度高,提高了墙面平整度,实现了薄浆砌筑一次成墙,节省了墙面再粉刷层环节,大幅提高了施工效率,降低了工程造价,对促进工业脱硫石膏的大宗资源化综合利用具有创新示范和推广应用价值。This paper introduces the selection of raw materials,technological process,product quality,improvement measures,engineering application and economic analysis for the production of high-strength and high-precision block by using desulfurized gyp-sum as bulk resources utilization. The high-strength high-precision block has high strength,good water resistance,no cavitation,no cracking,no refrost and alkalization after reasonably adding a certain proportion of new mineralizer. The mortise and tenon joint structure is reasonable,geometric size of each block of high precision,improves the wall roughness,implements the grout masonry into a wall at a time,which avoid the metope paint layer,greatly improve the construction efficiency,reduce the project cost. It has innovation demonstration and popularization and application value in promoting industrial bulk resource comprehensive utilization of desulfurization gypsum.
