Mineralizing agent for high-strength water-resistant gypsum product as well as preparation method and application of mineralizing agent
The invention belongs to the technical field of production of building material products from industrial solid waste desulfurized gypsum, and particularly relates to a mineralizer for a high-strength water-resistant gypsum product and a preparation method and application thereof, and the mineralizer for the high-strength water-resistant gypsum product comprises the following raw materials: 50-70 parts of lime, 15-30 parts of silica fume and/or silica powder, 10-20 parts of high-alumina cement, 1-4 parts of mineral powder and 1-6 parts of an auxiliary agent. The mineralizing agent is prepared from the lime, the silica fume and/or the silica powder, the high-alumina cement, the mineral powder and the auxiliaries as raw materials and is used for improving the water resistance and the strength of a gypsum product, and the initial setting time and the final setting time are relatively prolonged by doping the mineralizing agent; after the mineralizer is doped into the desulfurized gypsum, the formation of high-strength minerals and water-resistant minerals can be promoted, and the desulfurized gypsum can be better fused with trace elements of the mineralizer, so that the gypsum generates hydraulicity mutation, the strength and the water resistance of a gypsum product are remarkably improved, and meanwhile, the alkali and frost return phenomenon of the desulfurized gypsum product is also improved and eliminated.
本发明属于工业固废脱硫石膏生产建筑材料制品技术领域，具体为一种高强耐水石膏制品用矿化剂及其制备方法和应用，高强耐水石膏制品用矿化剂原料为石灰50‑70份、硅灰和/或硅粉15‑30份、高铝水泥10‑20份、矿粉1‑4份、助剂1‑6份。本发明以石灰、硅灰和/或硅粉、高铝水泥、矿粉和助剂为原料制备一种矿化剂，用于改进石膏制品的耐水性和强度，矿化剂的掺入使得初凝和终凝时间相对延长；将矿化剂掺入脱硫石膏后，可以促进高强矿物和耐水矿物的形成，使得脱硫石膏可以和矿化剂本身的微量元素更好地融合，从而使石膏产生水硬性突变，显著提高石膏制品的强度和耐水性，同时也改善和消除了脱硫石膏制品返碱返霜现象。
