High-strength cement-based non-shrinkage grouting material

The invention discloses a high-strength cement-based non-shrinkage grouting material which is prepared from the following raw materials in parts by weight: 100 parts of cement, 150-180 parts of river sand, 1-2 parts of water reducing agent, 0.1-0.3 part of defoaming agent, 0.8-1.2 parts of retarder, 0.7-0.85 part of reinforcing agent and 0.2-0.35 part of hollow polymer microspheres through dry mixing. The microspheres adopted in the high-strength cement-based non-shrinkage grouting material can both make the cement base material be denser and improve the strength of the material, the components are reasonably matched, and the interface acting force is strong; the obtained grouting material has excellent liquidity and strength performance, thereby being capable of being applied in large equipment installation, bolt anchoring and structure reinforcement.
