Muck-based magnesium phosphate salt geopolymer as well as firing-free preparation method and application thereof
The invention provides a muck-based magnesium phosphate salt geopolymer as well as a firing-free preparation method and application thereof, and relates to the technical field of building materials. Geopolymer slurry containing 10-50 parts of shield muck powder, 20-40 parts of dihydric phosphate, 40-90 parts of dead burned magnesium oxide, 10-30 parts of water, 0-15 parts of borax and 0-5 parts of an acid additive is poured and then vibrated and formed, curing is conducted after hardening is conducted at the temperature of 20-25 DEG C, and the muck-based magnesium phosphate salt geopolymer is obtained. The magnesium phosphate cement has huge early heat release and phosphate radical protonation effect, the problems of low shield muck utilization rate, low treatment efficiency, low strength and the like are solved, the energy-saving and low-carbon requirements are met, and the prepared geopolymer has high early strength; meanwhile, the shield muck is used for replacing a certain mass of magnesium phosphate cement, so that the problems that the magnesium phosphate cement is high in production cost, high in setting speed, limited in construction operation time, large and concentrated in heat release and the like are solved.
本发明提供了一种渣土基磷酸镁盐地聚合物及其免烧制备方法和应用，涉及建筑材料技术领域。本发明将含盾构渣土粉末10～50份，磷酸二氢盐20～40份，重烧氧化镁40～90份，水10～30份，硼砂0～15份，酸类外加剂0～5份的地聚合物浆体进行浇筑后振捣成型，在20～25℃下硬化后养护，得到渣土基磷酸镁盐地聚合物。本发明利用磷酸镁水泥早期放热量巨大，发生磷酸根质子化效应，解决了盾构渣土利用率低、处理效率低、强度低等问题并满足节能和低碳的要求，制备的地聚合物早期强度高；同时用盾构渣土取代一定质量的磷酸镁水泥，解决了磷酸镁水泥生产成本高、凝结速度快、施工操作时间有一定限制以及放热量大且集中等问题。
