Superfluid grouting material is composed of high-strength materials as aggregates, cement as a binder, and supplemented with high fluidity, slight expansion, anti-segregation, and other substances. Upon adding a certain amount of water at the construction site and thorough mixing, it is ready for use. The grouting material features excellent self-leveling, rapid hardening, early strength, high strength, no shrinkage, slight expansion; it is non-toxic, harmless, non-aging, and does not contaminate water quality or the surrounding environment. It also has good self-sealing properties and anti-rust characteristics. During construction, it offers reliable quality, cost reduction, time-saving, and ease of use. It fundamentally alters the load-bearing conditions of equipment bases, ensuring uniform distribution of the equipment's full load, thereby meeting the installation requirements of various mechanical and electrical equipment (heavy-duty high-precision grinding machines). It is the ideal grouting material for the era of no-padding installation.
Grouting materials are primarily used for: anchor bolt anchoring, emergency repairs of runways, equipment fixation, reinforcement of road and bridge projects, machine bases, steel structures and foundation sockets, secondary grouting of equipment foundations, embedded steel reinforcement, reinforcement and renovation of concrete structures, crack treatment of old concrete structures, installation of mechanical and electrical equipment, track and steel structure installation, static pile engineering pile sealing, thickening and repair of wall structures for leakage and seepage, grouting for various foundation collapses, and various emergency repair projects.

Other performance specifications
1. Reinforcement Bond Strength
The bond strength of round rebars within a day exceeds 6.0 MPa, and for ribbed rebars, it surpasses 13.0 MPa. Therefore, CGM grouting material can partially replace epoxy resin as the anchor material for anchor bolts.
2. Impermeability
The CGM grouting material exhibits superior impermeability compared to general waterproof concrete. Multiple tests, including oil penetration rate, oil penetration depth, and strength growth rate, indicate that the material maintains its strength after being soaked in oil, demonstrating excellent resistance to oil penetration.
3. Low temperature and freeze-thaw properties
CGM boasts excellent low-temperature properties. Its 7-day compressive strength remains above 30MPa when used at -5℃ for refrigerators and -10℃ for the environment. After being cured at standard temperature, its compressive strength rapidly increases, meeting the engineering design and construction requirements at lower temperatures. The low-temperature CGM maintains almost no strength loss after freeze-thaw cycles, making it suitable for installation projects in freeze-thaw environments.
4. Does not cause reinforcement corrosion
CGM grouting materials often come into long-term contact with steel reinforcement and iron equipment foundations. Tests indicate that its series products are in a passivated state (0-300mV) under natural potential; after the test blocks are split, there is no corrosion on the embedded steel reinforcement. Therefore, it can be said that CGM grouting materials will not cause steel reinforcement corrosion.
CGM grouting material boasts excellent fatigue resistance. After 2 million fatigue tests, the static compressive strength remains high, whereas the same grade of common concrete would have failed at 150,000 cycles under the same conditions. Domestic and international data indicate that the elastic modulus of grouting material is generally lower than that of regular concrete, which is beneficial in reducing the impact pressure on the foundation from the vibration loads of equipment. During the expansion observation of CGM grouting material, there are certain fluctuations in the expansion rate. After several tests and analyses, and excluding the influence of experimental errors, it may be due to the varying hydration of minerals in the cement clinker, a mechanism that awaits confirmation. In summary, CGM grouting material exhibits excellent engineering properties and a wide range of applications, making it a superior grouting material.
1. CGM grouting material boasts excellent fluidity, suitable for secondary grouting of equipment, anchoring of foot bolts, and engineering maintenance.
2. The initial setting time, final setting time, and expansion rate of CGM grouting material all meet the requirements of engineering design and construction.
3. CGM Grouting Material boasts high compressive strength, fully meeting the strength requirements of both domestic and imported equipment for grouting bodies.
4. CGM grouting material boasts high bonding strength with steel bars, can substitute epoxy resin as anchor material for anchor bolts, and has no corrosion effect on steel bars under natural potential.
5. CGM grouting material features excellent water resistance and strong oil penetration and erosion resistance. It maintains high strength under low temperatures and also has good frost-heaving resistance.
