Multi-solid-waste compounded retarded expansive cement and preparation method thereof
The invention belongs to the technical field of cement binding materials, and particularly relates to multi-solid-waste compounded delayed-setting expansive cement and a preparation method thereof. The retarded expansive cement provided by the invention comprises a cement material compounded by multiple solid wastes and a compound activator, the multi-solid-waste compounded cement material comprises 40-50% of cement clinker powder, 40-45% of thermal power plant circulating fluidized bed ash powder, 3-7% of desulfurized gypsum, 2-8% of silica fume, 2-5% of S95 mineral powder and 3-5% of steel slag powder. The exciting agent comprises triethanolamine, sodium gluconate and sodium sulfate. Through cooperative use of the raw materials, the strength and durability of the cement are improved, and meanwhile, the expansibility of the cement becomes controllable; the cement provided by the invention is stable and controllable in expansion rate, prolongs the initial and final setting time of the cement, is convenient for engineering construction, has excellent strength performance, and has remarkable environmental benefits and social and economic benefits.
本发明属于水泥胶凝材料技术领域，具体涉及一种多固废复配的缓凝膨胀水泥和制备方法。本发明提供的缓凝膨胀水泥，包括多固废复配的水泥材料和复配激发剂；所述多固废复配的水泥材料包括：水泥熟料粉40～50％，火力发电厂循环流化床灰渣粉40～45％，脱硫石膏3～7％，硅灰2～8％，S95矿粉2～5％，钢渣粉3～5％；所述激发剂包括三乙醇胺、葡萄糖酸钠和硫酸钠。本发明通过上述原料的配合使用，改善了水泥强度和耐久性，同时令水泥的膨胀性变得可控；本发明提供的水泥膨胀率稳定可控，并且延长了水泥初终凝时间，便于工程施工，同时具有优良的强度性能，具有显著的环境效益和社会经济效益。
