Geopolymer mortar and preparation method thereof
The invention discloses geopolymer mortar and a preparation method thereof, and belongs to the technical field of building materials. The geopolymer mortar comprises the following raw materials: oil shale ash, silica fume, fine aggregate, a composite activator, modified straw, zeolite powder, a water reducer, a retarder and a waterproof agent, and the oil shale ash and aluminum-containing wastewater are used as the raw materials of the geopolymer mortar, so that treatment and resource utilization of by-products and wastewater of oil shale production are realized; meanwhile, the oil shale ash, the silica fume, the zeolite powder and the fine aggregate with different particle sizes are selected, so that the structure of the geopolymer mortar is denser, the straw has certain tensile property after being treated by phenolic resin, and the composite exciting agent is added in batches, so that the mortar obtains higher fluidity and longer coagulation time; according to the preparation method, the raw material types, dosage and preparation parameters are reasonably designed, so that the performance of the prepared geopolymer mortar can meet the application requirements, and the geopolymer mortar has more excellent performance.
本发明公开了一种地质聚合物砂浆及其制备方法，属于建筑材料技术领域。该地质聚合物砂浆原料包括油页岩灰渣、硅灰、细骨料、复合激发剂、改性秸秆、沸石粉、减水剂、缓凝剂和防水剂，将油页岩灰渣、含铝废水作为地质聚合物砂浆的原料，从而实现油页岩生产的副产物和废水的处理及资源化利用，同时选用不同粒径的油页岩灰渣、硅灰、沸石粉和细骨料，使地质聚合物砂浆结构更密实，秸秆经酚醛树脂处理后具有一定的拉伸性能，复合激发剂分批次加入，使砂浆获得了更高的流动度和更长的凝结时间，对原料种类、用量及制备参数进行合理设计，使制备得到的地质聚合物砂浆的性能可以满足应用要求，具备更优异的性能。
