High-strength non-shrinkage grouting material is made of high-strength material as aggregate, cement as binder and other substances with high fluidity, micro-expansion and anti-segregation.

High strength non-shrinkage grouting material has good fluidity, micro-expansibility, early strength, high strength and oil permeability resistance. It has a wide application range and can meet the construction needs of various grouting projects. It is machinery and equipment in metallurgical, electric power, petrochemical, chemical and light industries. In the construction, it has the advantages of reliable quality, low cost, short construction period and convenient use.

The invention does not contain iron ions and chloride salts, and has the advantages of early strength, high strength, slight expansion, good fluidity, no corrosion, impact resistance and vibration resistance. The slurry can flow by itself, and the grouting material can automatically fill the narrow gap without vibration, which is suitable for grouting with complex structure, dense steel bars and narrow space.

Extended data

Characteristics of high strength non-shrinkage grouting material;

1, early strength, high strength: 1-3 days compressive strength can reach more than 30-50Mpa.

2. High gravity flow: it can fill all gaps and meet the requirements of secondary grouting of equipment.

3. Micro-expansibility: ensure that the equipment is in close contact with the foundation, and there is no shrinkage after secondary grouting. The bonding strength is high and the clamping force with round steel is not less than 6Mpa.

4. Winter construction: outdoor construction is allowed at-10℃.

5. Strong durability: this product is an inorganic cementing material, and its service life is longer than that of foundation concrete. After millions of fatigue tests, the strength of 50 freeze-thaw cycles has no obvious change. After soaking in engine oil for 30 days, the strength is obviously improved.
