Gypsum system excited composite cementing material and preparation method thereof
The invention discloses a gypsum system excited composite cementing material. The invention relates to the technical field of composite cementing material preparation. The gypsum-based composite material comprises gypsum-based composite powder and excitant powder, wherein the gypsum system composite powder comprises 25%-65% of industrial by-product gypsum, 30%-70% of slag powder and 3%-20% of Portland cement clinker; the excitant powder comprises 35%-50% of aluminum sulfate, 28%-60% of sodium aluminate and 5%-25% of calcium oxide. The preparation method of the gypsum system excited composite cementing material comprises the following steps: mixing industrial byproduct gypsum, slag powder and Portland cement clinker to obtain gypsum system composite powder; uniformly mixing aluminum sulfate, sodium aluminate and calcium oxide to obtain an excitant powder material; and uniformly mixing the gypsum system composite powder and the excitant powder material to obtain the gypsum system composite cementing material. According to the invention, resource comprehensive utilization of the common industrial solid wastes (slag powder and industrial by-product gypsum) is achieved, so that the cementing material is beneficial to environmental protection.
本发明公开了一种石膏体系激发复合胶凝材料，涉及复合胶凝材料制备技术领域，包括石膏体系复合粉体和激发剂粉体，其中，石膏体系复合粉体包括25％‑65％的工业副产石膏、30％‑70％的矿渣粉和3％‑20％的硅酸盐水泥熟料，激发剂粉体包括35％‑50％的硫酸铝、28％‑60％的铝酸钠、5％一25％的氧化钙。石膏体系激发复合胶凝材料的制备方法包括混合工业副产石膏、矿渣粉、硅酸盐水泥熟料得到石膏体系复合粉体；混合均匀硫酸铝、铝酸钠、氧化钙得到激发剂粉体材料；混合均匀石膏体系复合粉体与激发剂粉体材料，得到石膏体系复合胶凝材料。本发明将矿渣粉、工业副产石膏这种普遍工业固体废弃物的资源化综合利用有利于环境保护。
