Preparation method of moisture-proof and waterproof mortar for repairing ancient buildings
The invention discloses a preparation method of moisture-proof waterproof mortar for repairing ancient buildings, and belongs to the technical field of modification research of building materials and cultural relic protection materials. Metakaolin is adopted to partially replace traditional air hardening lime to serve as a cementing material main body, and a certain amount of aluminate coupling agent emulsion is prepared and added to prepare mortar. According to the modified mortar prepared by the method, under the high-humidity (RH = 85%) curing condition, the volume shrinkage can be reduced to a certain extent, the breaking strength can be quickly improved in the early stage of curing, and the compressive strength and the waterproof performance can be greatly improved when the curing time reaches 90 days. The mortar prepared by the preparation method has excellent moisture resistance and water resistance, can be applied to a high-humidity environment, and has important significance in breaking through the limitation of traditional mortar construction and use conditions.
一种古建筑修复用耐湿防水灰浆制备方法，属于建筑材料与文物保护材料改性研究技术领域。采用偏高岭土部分替代传统气硬性石灰作为胶结材料主体，制备并添加一定量铝酸酯偶联剂乳液配制灰浆。依上述方法配制的改性灰浆，能在高湿度(RH＝85％)养护条件下，一定幅度减小体积收缩，养护前期较快提升抗折强度，养护达到90天时能大幅提高抗压强度及防水性能。该种制备方法制备的灰浆具有优异的耐湿防水性，能够应用于高湿度的环境，在打破传统灰浆施工及使用条件局限性方面具有重要意义。
