Abstract

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.

Description

technical field

[0001] The invention belongs to the technical field of cement-based materials, and in particular relates to a high-strength cement-based non-shrinkage grouting material. Background technique

[0002] Cement-based non-shrinkage grouting material has the characteristics of good self-flow, rapid hardening, high strength, micro-expansion, non-toxic and harmless, no aging, no pollution, anti-rust, convenient construction, etc. It is widely used for anchoring anchor bolts, fixing nuclear power equipment, Secondary grouting of equipment foundation, reinforcement and transformation of embedded reinforced concrete structures, crack treatment of old concrete structures, etc. It has been mainly used for equipment foundation grouting at the beginning, and has developed into a series of products that can be used for various purposes such as building foundation reinforcement, building reinforcement, building beams, slabs, and columns.

[0003] In order to obtain ideal rei...
