Preparation method of low-temperature-resistant geopolymer repair mortar
The invention relates to the technical field of repair mortar preparation, and discloses a preparation method of low-temperature-resistant geopolymer repair mortar, which comprises the following preparation steps: S1, preparing raw materials: sand, cement, gel, fiber, a sodium hydroxide solution, a water reducing agent and a defoaming agent; s2, dry stirring: putting the sand, the cement, the gelling agent and the fiber into a stirring device, and mixing and stirring for a period of time to obtain a uniformly mixed solid material; s3, water type stirring: putting a sodium hydroxide solution, a water reducing agent and a defoaming agent into another stirring device, and mixing and stirring to obtain a mixed liquid; s4, preparing: stirring the solid material obtained in the step S2 and the mixed liquid obtained in the step S3 in a new stirring device, and standing for 60 seconds after stirring is finished, so as to finally obtain the repair mortar. The prepared repairing mortar is simple in mode, materials are easy to obtain and not expensive, and the repairing mortar has low-temperature resistance and can be used under the low-temperature condition.
本发明本发明涉及修补砂浆制备技术领域，且公开了一种耐低温地聚合物修补砂浆的制备方法，包括以下制备步骤：S1：准备原料：砂子、水泥、胶凝、纤维、氢氧化钠溶液、减水剂、消泡剂；S2：干式搅拌：将砂子、水泥、胶凝、纤维放入搅拌装置内进行混合搅拌一段时间，然后可以得到混合均匀的固体物料；S3：水式搅拌：将氢氧化钠溶液、减水剂、消泡剂放入另一个搅拌装置内混合搅拌，便可以得到混合液体；S4：制备：将由S2步骤得到的固体物料与由S3步骤得到的混合液体放置新的搅拌装置内进行搅拌，搅拌结束后进行静置60s，最后就可以得到修补砂浆。本发明所制备的修补砂浆方式简单，材料易得，不昂贵，具有耐低温的性能，可在低温情况下进行使用。
