CGM High-Strength Non-Shrink Grouting Material
Product Features: 1. Early and high strength: Compressive strength ≥27 MPa within 1 day; ≥40 MPa within 3 days; ≥60 MPa within 28 days.
2. Microexpansive
Ensure tight contact between the equipment and foundation, with no shrinkage after secondary grouting.
3. High self-leveling
Fills all voids, meets the requirements for secondary grouting of equipment.
4. Anti-settling
Overcame the phenomenon of segregation caused by excessive water addition during on-site use.
5. Crack-resistant
Cracking phenomena during on-site use due to uncertain water content, fluctuating environmental temperatures, and limitations on maintenance conditions.
6. High durability
After 500,000 fatigue tests and 50 freeze-thaw cycles, there is no significant change in strength. After soaking in engine oil for 30 days, the strength significantly improves.
7. Suitable for winter construction
Outdoor construction is permitted at temperatures as low as -10°C.
Product Application:
1. Used for secondary grouting of equipment foundations.
2. For anchoring ground bolts and reinforcing bar embedding.
3. Used for reinforcement and repair of concrete structures.

Grouting construction
Step 1: Basic Processing
The base surface should be roughened. Clean the base surface, free from debris such as gravel, slurry, loose dust, oil stains, and release agents. Prior to grouting, the base surface should be thoroughly moistened 24 hours in advance, and standing water should be cleared 1 hour before grouting.
Step 2: Feel and inspect
1. Set up forms according to the grouting construction drawing. Seal the joints between the forms and the foundation, as well as between forms, using cement grout and tape to ensure the entire form set is watertight.
2. The horizontal distance around the template and equipment base should be maintained at about 100mm to facilitate grouting work.
3. The template top elevation should be 50mm higher than the surface of the equipment base.
4. If there is any leakage during the grouting process, it should be addressed promptly.
Step 3: Grout Material Preparation
Generally, water is mixed at a standard of 13-14% for general reinforced type, and 9-10% for pebble reinforced type.
2. Use mechanical stirring method; stirring time is generally 1-2 minutes (drills with electric drill-style stirrers are strictly prohibited). When stirring manually, first mix with 2/3 of the water for 2 minutes, then add the remaining water and stir until uniform.
3. The mixing quantity should be determined based on the usage amount to ensure the material is used up within 40 minutes.
4. Under no circumstances should any admixture or external additive be mixed with CGM grouting material during on-site use.
Step 4: Grouting Construction Method
1. For longer equipment or track foundations, segmented construction should be employed.
2. Illustrations of Common Grouting Methods
3. During the secondary grouting, the following requirements should be met.
1.1 During secondary grouting, the grout should be applied from multiple points on one side or adjacent sides until it overflows from the opposite side, to facilitate air release during the grouting process. Grouting from all four sides simultaneously is not allowed.
1.2 Once grouting begins, it must be conducted continuously without interruption, and efforts should be made to minimize the grouting time.
1.3 It is strictly forbidden to vibrate during the grouting process. If necessary, use a grouting booster to push the CGM grouting material along the bottom of the grouting layer, strictly prohibiting pushing from the middle or upper part of the grouting layer to ensure the homogeneity of the grouting layer.
After the equipment foundation grouting is completed, a 45-degree bevel should be cut along the edge of the equipment within 3-6 hours post-grouting (refer to the illustration below) to prevent cracks from forming at the ends. If edge trimming is not possible, the grouting layer surface should be smoothed with a trowel within 3-6 hours after grouting.
When the thickness of the grouting layer exceeds 150mm, it is recommended to use reinforced coarse aggregate high-strength shrinkage-free grouting material.
1.6 When the amount of equipment base grouting is large, mechanical mixing should be used for the stone reinforcement grouting material to ensure the grouting construction.
Step 5: Maintenance
1. Immediately cover with a wet straw mat or rock wool blanket within 30 minutes after grouting, and maintain its moisture.
2. During winter construction, the maintenance measures should also comply with the relevant provisions of the current (GB50204).
3. After the grouting material reaches the demolding time, the equipment installation can be carried out. Please refer to the "Demolding and Curing Time vs. Environmental Temperature Chart" for the specific time.
4. After the equipment foundation grouting is completed, if any parts need to be removed, they can be gently scraped off with a trowel or shovel tool 3-6 hours after grouting, before the grout hardens.
5. Do not transmit vibration from operating machinery to the equipment foundation. After secondary grouting, the machine should be shut down for 24-36 hours to prevent damage to the unhardened grout layer.
