Other performance specifications
1. Reinforcement Bond Strength
The bond strength of round rebars has exceeded within a day.6.0 MPa, the one-day bond strength of the threaded steel bars has exceeded 13.0 MPa. Therefore, CGM grouting material can partially replace epoxy resin as the anchoring material for anchor bolts.
2. Impermeability
CGM grouting material has significantly better water 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 good resistance to oil penetration.
3. Low-temperature and freeze-thaw properties
CGM boasts excellent low-temperature performance, with a 7-day compressive strength of no less than 30MPa when used at -5℃ for the refrigerator and -10℃ for the environment. After standard temperature curing, its compressive strength increases immediately, meeting the engineering design and construction requirements at lower temperatures. The low-temperature version of CGM retains almost no strength loss after freezing and thawing, making it suitable for equipment installation projects in freeze-thaw environments.
4. Does not cause reinforcement corrosion
CGM grouting materials often have long-term contact with reinforcing steel and iron equipment foundations. Tests indicate that its product series is in a passivated state (0 to 300mV) under natural potential; after splitting the test blocks, no corrosion is found on the embedded reinforcing steel. Therefore, it can be said that CGM grouting materials do not cause reinforcing steel corrosion.
CGM grouting material exhibits excellent fatigue resistance, maintaining high static compressive strength after 2 million fatigue tests, whereas ordinary concrete of the same grade would have failed after 150,000 cycles under the same conditions. According to domestic and international data, the elastic modulus of grouting material is generally lower than that of ordinary concrete, which is beneficial in reducing the impact pressure on the foundation due to equipment vibration loads. During the expansion observation of CGM grouting material, there are certain fluctuations in the expansion rate. After several tests and analyses, excluding the impact of experimental errors, it is likely influenced by the different hydration of minerals in the cement clinker, a mechanism yet to be confirmed. In summary, CGM grouting material boasts excellent engineering properties, wide applicability, and is 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 materials 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 rebar, making it a suitable alternative to epoxy resin as anchor material for foundation bolts, and it does not cause rust on rebar under natural potential.
5. CGM grouting material boasts excellent water resistance, strong oil penetration and erosion resistance, higher strength at low temperatures, and good freeze-thaw resistance.
