Dry-mixed adhesive mortar prepared from coal gangue and fly ash and preparation method of dry-mixed adhesive mortar
The invention relates to the technical field of building materials, in particular to dry-mixed adhesive mortar prepared from coal gangue and fly ash and a preparation method of the dry-mixed adhesive mortar. The dry-mixed adhesive mortar prepared from coal gangue and fly ash is prepared by mixing coal gangue aggregate, stone powder, ordinary Portland cement, slaked lime, fly ash, redispersible latex powder, cellulose and starch ether. The physical characteristics of coal-based solid wastes such as coal gangue and fly ash are fully utilized, resource utilization of the coal-based solid wastes is realized, and the prepared dry-mixed adhesive mortar meets the national standard, has the characteristics of high compressive strength, high bonding strength and the like, and has important economic benefits and environmental benefits.
本发明涉及建筑材料技术领域，尤其涉及一种用煤矸石和粉煤灰制备的干混粘结砂浆及其制备方法。所述一种用煤矸石和粉煤灰制备的干混粘结砂浆，由煤矸石骨料、石粉、普通硅酸盐水泥、消石灰、粉煤灰、可再分散乳胶粉、纤维素、淀粉醚混合而成。本发明不但充分利用了煤矸石、粉煤灰等煤基固废的物理特性，实现了煤基固废的资源化利用，而且制备的干混粘结砂浆符合国家标准，并具有抗压强度高、粘接强度大等特性，具有重要的经济效益及环境效益。
