Grouting material (cement-based) is a cement-based grouting material that is made up of high-strength materials as aggregates, cement as binders, and supplemented with substances such as high flowability, micro expansion, and anti segregation. Add a certain amount of water to the construction site, mix it evenly, and it can be used. Has good self flow, fast hardening, early strength, high strength, no shrinkage, and slight expansion; Non toxic, harmless, non aging, non polluting to water quality and surrounding environment, good self sealing, rust proof and other characteristics. In terms of construction, it has the advantages of reliable quality, cost reduction, shortened construction period, and convenient use. Fundamentally changing the force situation of the equipment base to evenly bear all the loads of the equipment, thus meeting the installation requirements of various mechanical and electrical equipment (high-precision grinding machines for heavy equipment), is an ideal grouting material for the era of pad free installation.
Application scenarios:
Mainly used for anchoring anchor bolts, repairing airplane runways, fixing nuclear power equipment, reinforcing road and bridge engineering, machine bases, steel structures and foundation cups, secondary grouting of equipment foundations, embedding of steel bars, reinforcement and renovation of concrete structures, crack treatment of old concrete structures, installation of mechanical and electrical equipment, installation of tracks and steel structures, sealing of static pile engineering, thickening of wall structures and repair of leakage water, collapse grouting of various foundation engineering, and various emergency repair projects.

Main product features:
1. Early strength and high strength: Grouting materials have the characteristics of early strength and high strength, with a maximum strength of over 60MPa per day. The equipment can be put into operation and production after one day of installation. The compressive strength can reach over 30-50Mpa within 1-3 days.
2. Self flowing state: The grouting material only needs to be mixed with water on site and directly injected into the equipment foundation without vibration to fill all the gaps in the equipment foundation.
3. Micro expansion: The grouting material has micro expansion properties to ensure close contact between the equipment and the foundation, and there is no shrinkage after secondary grouting.
4. No corrosion effect: The grouting material has no corrosion hazard to steel bars, steel plates, etc.
5. Oil resistance: After soaking in engine oil for 30 days, its strength increases by more than 10% compared to before immersion.
6. Good weather resistance: The grouting material can be safely used for a long time within the temperature range of -40 ℃ to 600 ℃.
7. Strong durability: Grouting material is an inorganic bonding material with a service life greater than that of foundation concrete. After millions of fatigue tests, there is no significant change in strength after 50 freeze-thaw cycles.
8. Construction in winter: Outdoor construction is allowed at a temperature of -10 ℃.
9. Good fire resistance and high temperature resistance: Grouting material can be used as a protective material, and in many cases, no additional protective layer is required.
10. Environmental friendliness: The grouting material has excellent water solubility, low viscosity, and excellent injectability. It can also flow smoothly and efficiently fill small pores. Low toxicity, environmentally friendly, and widely used in some projects with high environmental requirements.
Used for anchoring anchor bolts, embedding steel bars, anchoring bolts, planting steel bars, and reinforcing concrete in building structures.
Used for concrete structure reinforcement and repair, beam column section enlargement reinforcement engineering, etc.
Suitable for equipment foundation secondary grouting, track foundation, bridge support seat and other high-pressure areas grouting, etc.
