Preparation method of salt gypsum-based high-strength shrinkage-free grouting material
The invention discloses a preparation method of a salt gypsum-based high-strength shrinkage-free grouting material. The method comprises the following steps: uniformly mixing salt gypsum, fly ash, slag powder, cement clinker and a water reducing agent, adding water according to the water-cement ratio of 0.2: 1, and uniformly stirring to obtain a high-flowability grouting material. More than 80% ofthe used materials are industrial wastes, have excellent characteristics of high strength and no shrinkage, overcome the defect that a cement-based grouting material is liable to shrink, are good substitute products for the cement-based grouting material, and can generate good economic benefits, social benefits and environmental benefits.
本发明公开了一种盐石膏基高强无收缩灌浆材料制备方法，包括如下步骤：将盐石膏、粉煤灰、矿渣粉、水泥熟料和减水剂混合均匀即可，混合均匀后，按照水灰比0.2:1的比例加水搅拌均匀后，即可制得高流动性的灌浆材料。本发明所利用的材料80％以上为工业废物，具有高强无收缩的优良特性，克服了水泥基灌浆材料易收缩的缺点，是水泥基灌浆材料很好的替代产品，能够产生很好的经济效益、社会效益和环境效益。
