H60 High-Strength Non-Shrink Grouting Material is a high-performance cement-based composite material, specifically designed for high-strength load-bearing scenarios such as precision equipment installation and steel structure anchoring. It features self-leveling, non-shrinking, and early-strength/high-strength properties.
Technical Specifications
(Core parameters are presented in tabular form, including key data such as compressive strength, fluidity, vertical expansion rate, etc., meeting the ASTM C1107/CGM standard.)
Functions and Features
Ultra-high strength: Rapid early-strength development, capable of bearing loads within 24 hours.
Non-shrink property: Ensures tight bonding between the grout and the base material, preventing hollowing and cracking.
Self-leveling construction: No vibration required, capable of filling complex gaps.
Fatigue and impact resistance: Adaptable to dynamic load scenarios, such as machine tool equipment foundations.
Scenario Applications
Anchoring of foundation bolts for large-scale mechanical equipment (such as injection molding machines and rolling mills).
Grouting for steel structure column bases.
Grouting for bridge bearings.
Reinforcement and repair of concrete structures.
Special engineering projects such as nuclear power plants and wind farms.
Construction Steps
Base Layer Preparation:
Chisel and clean the surface.
Sprinkle water to moisten, ensuring no standing water remains.
Mixing Ratio and Stirring:
Mechanically stir for 3-5 minutes with a water-to-material ratio of 13-15%.
Grouting Application:
Continuously pour from one side, allowing it to flow naturally to the other side.
Curing:
Cover and keep moist for 7 days. If the ambient temperature is below 5°C, take insulation measures.Precautions
The construction temperature must be within the range of 5 - 35℃.
For outdoor construction on rainy days, a protective canopy should be erected.
The mixed material must be used up within 30 minutes. Once this time limit is exceeded, the slurry will start to set and become ineffective.
It is strictly prohibited to arbitrarily adjust the amount of water added, as this may affect the strength.
Once the package is opened, the contents should be used up at one time to prevent moisture absorption and caking.Scenarios

Preparation
Before grouting, the surface of the base in contact with the grouting material should be cleaned and cleaned. 24 hours before grouting, the surface of the base concrete should be fully moistened. One hour before grouting, remove the accumulated water.
Grouting material preparation
1. When mixing cement-based grouting materials, add water according to the water consumption specified in the product qualification certificate. Weigh the water first, then pour the grouting material into the water and stir.
2. Before grouting, select (but not limited to) the following equipment and instruments according to the characteristics of on-site grouting: mechanical stirring; forced concrete mixer; manual stirring; hand-held drill stirrer. The mixing time is 3-5 minutes, and the mixing location should be close to the grouting material location. If there are a lot of bubbles on the surface, let it stand for 3 minutes before pouring, or you can tap the formwork appropriately.
3. Grouting should be continuous, and the mixed grouting material should be used up within 30 minutes.
4. Vibration is strictly prohibited during grouting. Appropriate insertion can be used, and the formwork can be tapped appropriately at the formwork.
Curing of grouting material
1. After grouting, the exposed parts should be sprayed with curing agent or covered with plastic film in time, and covered with wet straw bags to keep them moist.
2. When using plastic film to cover, the exposed surface of the grouting material should be covered tightly to keep condensation water inside the plastic film.
3. When the surface of the grouting material is inconvenient to water, a curing agent can be sprayed.
4. The watering curing time should be no less than 7d, and the number of watering times should keep the grouting material moist.
Precautions
1. According to the weather forecast. Avoid outdoor construction on rainy days. If the working surface is rained in the middle, a rain cloth should be set up in time. If rainwater is poured in, rework should be carried out in time.
2. The standard water consumption of this product is 0.12-0.14. The water-cement ratio is an important part of cement grouting material, and arbitrary addition of water will affect the product performance of cement grouting material.
3. Use special mechanical forced rapid stirring for 3-4min to prevent uneven stirring and mixing of raw materials, which will affect the later strength of cement grouting material. Do not use manual ground shovel mixing.
4. Pay attention to temperature changes before construction. Temperature affects the initial and final setting time and fluidity of the cement grout. The recommended construction temperature is 5-35℃. For low-temperature construction below zero, please inform our company in advance. We have corresponding high-early-strength and freeze-thaw resistant products.
5. Mechanical vibration is strictly prohibited during construction; however, channeling is allowed. Prevent stratification and bleeding of the cement grout.
6. The dry density of the cement grout is 2400KG/m³. Calculate the required amount based on the cubic meter of the project. Mix only the amount needed! Strictly prohibit mixing a large amount that will not be used to avoid waste. Leftover material is strictly prohibited from being remixed with the grout for reuse.
7. Strictly prohibit the arbitrary addition of any chemical substances on-site to alter the product performance of the cement grout.
8. This product must be protected from moisture or rain. It can only be reused after passing the quality inspection after the expiration date.
