Non-shrinkage cement-based grouting material having durability
The invention relates to a non-shrinkage cement-based grouting material having durability. The non-shrinkage cement-based grouting material is prepared by adopting the following raw materials in part by weight: 0.2 to 0.4 parts of defoaming agent, 15 to 25 parts of river sand, 14 to 20 parts of liquid material, 10 to 20 parts of polymer emulsion of cement-based formula, 30 to 45 parts of cement, 5 to 7 parts of Zhangwu clay, 3 to 5 parts of dolomite, 4 to 6 parts of Luan-County feldspar, 3 to 6 parts of Shanxi knag, 8 to 16 parts of ground mineral slag, 1 to 1.5 parts of retarder, 0.2 to 0.3 parts of plastic swelling agent, 6 to 12 parts of sodium formate, 10 to 14 parts of coal ash, 2 to 8 parts of mineral slag activity excitant and 0.1 to 0.2 parts of lithium carbonate. The non-shrinkage cement-based grouting material has the beneficial effects that the fracture can be prevented, the surface is prone to level, a micro film is formed, the water evaporation is reduced, dry shrinkage is reduced, the durability is good, and the application performance is improved.
