Quick-hardening early-strength muck geopolymer mortar as well as preparation method and application thereof
The invention provides quick-hardening early-strength muck geopolymer mortar as well as a preparation method and application thereof, and relates to the technical field of resource utilization of building materials. The muck geopolymer mortar provided by the invention is prepared from the following raw materials: engineering muck, slag, sand and an alkali activator. The quick-hardening early-strength muck geopolymer mortar is obtained by taking all-component engineering muck as a main raw material, introducing the slag and the sand, reasonably controlling the mixing ratio of all the components and utilizing an alkali activator technology. According to the method, all-component utilization of sand, stone and soil in the engineering residue soil can be achieved, and the engineering muck is recycled by 100%; and the obtained muck geopolymer mortar has mechanical strength similar to that of cement mortar and excellent rapid hardening and early strength performance, and can replace the cement mortar, so that the production of cement is reduced, a large amount of energy consumption generated by the high temperature of 1400 DEG C in the production process of the cement mortar is avoided. Meanwhile, compared with cement mortar, the emission of carbon dioxide can be reduced by 40-60%.
本发明提供了一种快硬早强渣土地聚物胶砂及其制备方法和应用，涉及建筑材料资源化利用技术领域。本发明提供的渣土地聚物胶砂包括以下制备原料：工程渣土、矿渣、砂和碱激发剂。本发明以全组分工程渣土为主原料，通过引入矿渣和砂，并合理控制各组分的配合比，利用碱激发剂技术获得一种快硬早强渣土地聚物胶砂。本发明能够实现工程渣土中砂、石、土的全组分利用，100％回收利用工程渣土；且得到的渣土地聚物胶砂具有和水泥胶砂相似的力学强度以及优越的快硬早强性能，可以替代水泥胶砂的使用，从而减少水泥的生产，避免水泥胶砂生产过程中1400℃的高温所产生的大量能耗，同时二氧化碳的排放量相比于水泥胶砂能够降低40～60％。
