High-Strength Non Shrink Grout
Product Application
It is typically used in the following scenarios:
Equipment Installation: Used to secure heavy machinery such as generators, compressors, pumps, etc., ensuring smooth operation and reducing vibrations.
Structural Strengthening: In bridges, tunnels, high-rise buildings, etc., used for filling and reinforcement to enhance overall stability and load-bearing capacity.
Prestressed Engineering: Used for duct grouting in prestressed concrete structures, ensuring effective anchorage between prestressing tendons and concrete.
Precision Instrument Installation: In situations requiring precise alignment and stability, such as laboratory equipment and optical instruments, providing a high-precision installation base.
This material usually possesses early strength and high strength, self-leveling properties, micro-expansion, non-corrosive to metal, oil resistance, among other features. After hardening, it provides excellent durability and weather resistance, meeting high engineering standards.

Product advantages
The high-strength non-shrink grout has numerous advantages in the construction and engineering industries due to its unique properties, including:
1.High Strength: It has very high compressive strength, capable of withstanding significant loads, suitable for supporting and reinforcing various structures, effectively enhancing load-bearing capacity and stability.
2.No Shrinkage: During curing, it does not shrink, meaning it can fill gaps without leaving voids or cracks, avoiding structural damage caused by shrinkage.
3.High Bonding Strength: The high-strength non-shrink grout can firmly bond concrete and foundation equipment, similar to super glue, with a micro-expansive nature that enhances bonding effectiveness.
4.Excellent Durability: Compared to ordinary grout, high-strength non-shrink grout has better durability, is resistant to aging, and is non-corrosive to metal equipment, surviving 2 million fatigue tests and 50 freeze-thaw cycles without significant changes in strength.
5.Good Weather Resistance: High-strength non-shrink grout can be safely used over a long period from -40°C to 600°C.
6.Convenient Construction: It can be easily made through simple mixing and stirring, with a quick construction process that significantly shortens project duration and enhances efficiency.
7.Early Strength and High Strength: It can achieve high strength within a short time, suitable for scenarios requiring rapid installation of foundation equipment.
8.Good Flowability: It has self-leveling properties, allowing it to flow freely and fill complex structural voids without vibration.
9.Environmental Advantages: It has a minimal environmental impact, meeting modern construction requirements for environmental protection.
10.Micro-expansion: During hardening, it undergoes slight expansion, which helps fill gaps and enhances the bond between the grout and the structure.
These advantages make high-strength non-shrink grout an essential material in modern construction engineering.
