High-efficiency solid waste-based cementing activity excitant
The invention relates to an efficient solid waste-based cementing activity activator, and relates to the field of material science and solid waste resource utilization. The problem that solid waste such as red mud, coal gangue and tailings is difficult to utilize is mainly solved, and the high-performance red mud-based cementing material is prepared. The efficient red mud-based cementing activityactivator comprises 40 to 60 parts of alkali metal silicate, 10 to 20 parts of alkali metal hydroxide, 0 to 15 parts of a high-calcium solid waste material, 4 to 8 parts of carbonate, 0 to 5 parts ofhydrotalcite and 0 to 8 parts of an imidazole porous crystal material. The prepared red mud-based cementing material has the advantages of high mechanical strength, short setting time and the like.
本发明涉及一种高效固废基胶凝活性激发剂，涉及材料科学及固废资源化利用领域。主要解决赤泥、煤矸石、尾矿等固体废弃物难以利用的难题，制备高性能赤泥基胶凝材料。一种高效赤泥胶凝活性激发剂其中，碱金属硅酸盐40‑60份，碱金属氢氧化物10‑20份，高钙固废材料0‑15份，碳酸盐4‑8份，水滑石0‑5份，咪唑类多孔晶体材料0‑8份。采用此制备的赤泥基胶凝材料具有力学强度高、凝结时间短等优点。
