Product Description
Grouting material for bearings is a specialized material designed specifically for engineering structures such as bridges and buildings. It is primarily composed of cement, aggregates, admixtures, and other ingredients, and boasts excellent fluidity and self-compacting properties. During the grouting process, it effectively fills the gaps between the bearing and the structural components, providing robust support and enhancing the overall integrity and stability of the structure. Moreover, bearing grouting material exhibits outstanding durability and resistance to aging, enabling it to withstand chemical corrosion and the effects of natural environments. This grouting material is easy to handle and highly efficient in construction, making it widely used in various types of engineering projects. It is one of the crucial materials for ensuring the quality and safety of engineering works.

5. Functional Features
Ultra-high strength: Early strength develops rapidly, and the material can bear loads within 24 hours.
Non-shrinking performance: Ensures tight bonding between the grouting material and the substrate, preventing voids and cracks.
Self-leveling construction: No vibration required, capable of filling complex gaps.
Fatigue and Impact Resistance: Adaptable to dynamic loading scenarios, such as machine tool foundations.6. Application Scenarios
7. Construction Steps
Grassroots Preparation:
Chisel and clean the surface.
Spray some water to keep it moist, making sure no standing water remains.
Mixing Ratio and Stirring:
Mix mechanically for 3 to 5 minutes with a water-to-material ratio of 13% to 15%.
Grouting applications:
Pour continuously from one side, allowing it to flow naturally to the other side.
Solidification:
Cover with a lid and keep moist for 7 days. If the ambient temperature falls below 5℃, please take measures to keep it warm.8. Precautions for Use
Construction ambient temperature -5 to 35℃ The water-to-cement ratio is an important performance indicator for this product. Please add water according to the manufacturer’s specified water-to-cement ratio and use mechanical equipment to ensure thorough, uniform mixing before construction! If the water-to-cement ratio is improperly adjusted, it may affect the product’s performance. This product is a finished item—do not add any other substances arbitrarily, as this could compromise its functionality and quality system! If this product has expired, it should be properly disposed of rather than reused. After mixing, any leftover material that has not been used must never be combined with fresh material for further use! When carrying out outdoor construction on rainy days, a rain shelter should be set up. The mixed materials must be... 30 Once the minute is up, the slurry will begin to set and lose its effectiveness once it exceeds the initial setting time! Once the package is opened, the contents should be used up in one go to prevent moisture absorption and clumping.
