Shrinkage-free cement-based grouting material
A shrinkage-free cement-based grouting material is composed of the following raw materials in parts by weight: 0.5 to 1.5 parts of retarder, 0.15 to 0.25 part of hollow polymer microsphere, 40 to 80 parts of cement, 8 to 24 parts of coarse-grain quartz sand, 0.1 to 0.2 part of bactericide, 16 to 28 parts of powder, 0.02 to 0.06 part of dispersant, 7 to 10 parts of calcined kaolin, 3 to 6 parts of Guangdong black mud, 6.5 to 8.2 parts of Zhanjiang B china clay, 2 to 3.5 parts of paddock clay, 8 to 20 parts of fly ash, 25 to 36 parts of metal oxide, 15 to 35 parts of rigid expanding agent, and 4 to 7 parts of performance conditioning agent. The provided shrinkage-free cement-based grouting material has the advantages of good thermal stability, high compressive strength, strong adhesive force, and prolonged service life, and reduces the construction difficulty.
