High-hardness cement mortar containing coal gangue and preparation process of high-hardness cement mortar
The invention relates to the technical field of cement mortar, and discloses high-hardness cement mortar containing coal gangue and a preparation process. The high-hardness cement mortar is prepared from cement, coal gangue, lime, gypsum, sand, ceramic particles, crushed crude pearlite, bentonite, latex powder, polystyrene fibers, steel fibers, clay, epoxy resin, modified calcium sulfate and a mixed additive. The cement mortar prepared from the coal gangue as a raw material has the characteristics of low pollution, low energy consumption and capability of enhancing the hardness of the cement mortar; the modified coal gangue has higher stability, so that the stability of the cement mortar can be enhanced, the phenomena of hollowing and dry cracking are avoided, the coal gangue is recycled as a solid waste material, the pollution to the environment is effectively reduced, the cement mortar is more energy-saving and environment-friendly, the preparation cost of the cement mortar can be effectively reduced, and the cement mortar has higher hardness and is suitable for popularization and application. The viscosity stability is higher, and the phenomena of separation and cracking after use can be avoided.
本发明涉及水泥砂浆技术领域，且公开了一种含有煤矸石的高硬度水泥砂浆以及制备工艺；所述高硬度水泥砂浆由水泥、煤矸石、石灰、石膏、砂、陶瓷粒、珍珠岩粉、膨润土、乳胶粉、聚丙乙烯纤维、钢纤维、粘土、环氧树脂、改性硫酸钙以及混合添加剂，本发明以煤矸石作为原料制备的水泥砂浆具有污染低、能耗少以及增强水泥砂浆硬度的特点，经过改性的煤矸石具有更高的稳定性，从而可增强水泥砂浆的稳定性，避免出现空鼓干裂的现象，且煤矸石作为固体废料得以重复利用，有效减少对环境的污染，更加节能环保，且可有效降低水泥砂浆的制备成本，且具有更强的硬度，更高的黏性稳定性，可避免使用后产生分离开裂的现象。
