Geopolymer repair material capable of being rapidly formed in low-cold climate and preparation method of geopolymer repair material
The invention discloses a geopolymer repair material capable of being rapidly formed in low-cold climate and a preparation method of the geopolymer repair material. The geopolymer repair material capable of being rapidly formed in the low-cold climate is prepared from the following raw materials: fire coal slag and a compound exciting agent, wherein the compound exciting agent is prepared from the following components in percentage by weight: 30 to 60 percent of calcium oxide, 20 to 50 percent of calcium hydroxide and 5 to 30 percent of aluminum phosphate. According to the invention, chemical excitation is carried out on the fire coal slag, and under a multi-calcium system, calcium oxide and calcium hydroxide are taken as starting factors of a chemical reaction, so that a favorable environment can be provided for the proceeding of the chemical reaction; and aluminum phosphate and calcium hydroxide are used as regulating agents, so that the heat release rate of the slurry can be effectively controlled, and the phenomena of premature hardening, bulging, cracking and the like caused by instantaneous heat release are prevented. The prepared repairing material can adapt to engineering application in low-cold climate areas, and is high in early-stage compressive strength and good in freezing resistance.
本发明公开一种在低寒气候下快速成型的地聚合物修复材料及其制备方法。该在低寒气候下快速成型的地聚合物修复材料的原料包括：燃煤渣和复配激发剂；其中，按重量百分比计，复配激发剂由以下组分组成：氧化钙30％～60％、氢氧化钙20％～50％、磷酸铝5％～30％。本发明通过对燃煤渣进行化学激发，在多钙体系下，氧化钙与氢氧化钙作为化学反应的启动因子可以为化学反应的进行提供有利的环境；通过使用磷酸铝和氢氧化钙作为调控剂，能够有效控制浆体的放热速率，防止因瞬时放热出现过早硬化、鼓胀和开裂等现象。本发明制备的修复材料能够适应低寒气候地区的工程应用，早期抗压强度高，抗冻性良好。
