High-calcium fly ash/cement composite cementing material cured clay and preparation method thereof
The invention provides high-calcium fly ash/cement composite cementing material cured clay and a preparation method thereof.The cured clay is prepared from, by mass, 0.09-0.18 part of solid waste, 0.02-0.06 part of cement and 1 part of clay, and the solid waste comprises high-calcium fly ash and slag; the alkali activator is a mixture of sodium hydroxide and water glass, and the modulus of the water glass is 1.4-2.0. During preparation, the solid waste, the cement and the clay are mixed to obtain a mixture; and adding the alkali activator, the water reducer and the water into the mixture, and uniformly mixing to obtain the clay cured by the high-calcium fly ash/cement composite cementing material. The clay is subjected to soil body reinforcement by using the solid waste and the cement, so that the unconfined compressive strength and the shear strength of the clay are remarkably improved.
本发明提供高钙粉煤灰/水泥复合胶凝材料固化的黏土及制备方法，所述固化的黏土按质量份数计，包括0.09～0.18份固废料、0.02～0.06份水泥和1份黏土，固废料包括高钙粉煤灰和矿渣；还包括碱激发剂、减水剂和水，碱激发剂为氢氧化钠和水玻璃的混合物，水玻璃的模数为1.4～2.0。在制备时，将固废料、水泥和黏土混合，得到混合料；再将碱激发剂、减水剂和水加入到混合料中，混合均匀，可得到高钙粉煤灰/水泥复合胶凝材料固化的黏土。本发明利用固废料和水泥对黏土进行土体加固，显著提高了黏土的无侧限抗压强度和抗剪强度。
