CGM High-Strength Non-Shrink Grouting Material
Product Features1. Early strength, with compressive strength of ≥27 MPa after 1 day; ≥40 MPa after 3 days; and ≥60 MPa after 28 days.
2. Microexpansivity
Ensure tight contact between the equipment and foundation, with no shrinkage after secondary grouting.
3. High fluidity
Fills all voids, meets the requirements for secondary grouting of equipment.
4. Anti-segregation
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 addition, ambient temperature, and limitations on maintenance conditions.

Grouting construction
Step 1: Basic Processing
The base surface should be roughened. Clean the base surface, ensuring there are no debris, float, loose dust, oil stains, and release agents, etc. Prior to grouting.24 hours, the base surface should be fully moistened; before grouting, remove any standing water 1 hour prior.
Two Steps: Feel and Touch
1. Set up forms according to the grouting construction drawing. Seal the joints between the forms and the foundation, as well as between the forms themselves, using cement grout and tape to ensure the entire form system is waterproof.
2. The horizontal distance around the template and base should be maintained at approximately 100mm to facilitate grouting work.
3. The template's top elevation should be 50mm higher than the surface of the equipment base.
4. In case of leakage during grouting, it should be addressed promptly.
Step 3: Grout Mixture Preparation
Generally, water is mixed according to a standard of 13-14% for general reinforced type, and 9-10% for aggregate reinforced type.
2. Mechanical stirring is used, with a general mixing time of 1-2 minutes (using a drill mixer is strictly prohibited). When mixing manually, first add 2/3 of the water and mix for 2 minutes, then add the remaining water and mix until uniform.
3. The mixing amount should be determined based on the usage quantity to ensure the material is used up within 40 minutes.
4. It is strictly prohibited to add any admixtures or external additives to 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. Diagrams of several commonly used grouting methods
3. During the secondary grouting, the following requirements should be met.
1.1 During secondary grouting, it should be performed from multiple points on one side or adjacent sides until it overflows from the opposite side, to facilitate air venting during the grouting process. Grouting from all four sides simultaneously is not permitted.
1.2 Once the grouting begins, it must be conducted continuously without interruption and the grouting time should be minimized as much as possible.
1.3 It is strictly prohibited 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, but严禁 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 equipment edge within 3-6 hours after grouting (refer to the illustration below) to prevent cracks from forming at the ends. If edge cutting 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, use reinforced stone aggregate high-strength shrinkage-free grouting material.
1.6 When the base grouting volume of the equipment is large, mechanical mixing should be used for the gravel reinforcement grouting material to ensure the grouting construction.
Step 5: Maintenance
1. Immediately cover with a wet straw blanket 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 complete, if any part needs to be removed, gently scrape it off with a spatula or shovel tool within 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 grouting layer.
