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. Microexpansivity
Ensure tight contact between the equipment and foundation, with no shrinkage after secondary grouting.
3. High fluidity
Fills all voids, meeting the secondary grouting requirements for equipment.
4. Anti-segregation
Overcame the phenomenon of segregation caused by excessive water addition during on-site use.
5. Crack Resistance
Cracking phenomena during on-site use due to factors such as uncertain water addition, uncertain environmental temperature, and limited curing conditions.
6. Strong durability
After one million fatigue tests and 50 freeze-thaw cycles, there is no significant change in strength. After soaking in engine oil for 30 days, the strength improves significantly.
7. Suitable for winter construction
Outdoor construction is permitted at temperatures as low as -10℃.
Product Application:
1. Used for secondary grouting of equipment foundations.
2. For anchoring foot 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, ensuring there is no debris such as gravel, slurry, loose dust, oil stains, and release agents. Prior to grouting 24 hours, the base surface should be thoroughly moistened. One hour before grouting, remove any standing water.
Step 2: Inspection
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 base should be maintained at approximately 100mm to facilitate grouting work.
3. The template 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 Material Preparation
Generally, add water to mix according to a standard of 13-14% for general reinforced type, and 9-10% for aggregate reinforced type.
2. Mechanical stirring is used, typically for 1-2 minutes (no electric drill stirrers allowed). 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. It is strictly prohibited to add any admixtures or external additives to the 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 the secondary grouting, grouting should be performed from multiple points on one side or both 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 After the grouting begins, it must be carried out continuously without interruption. Also, strive to minimize the grouting time.
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 strictly forbidden to push from the middle or upper part of the grouting layer to ensure the homogeneity of the grouting layer.
After the equipment base grouting is completed, a 45-degree bevel should be cut outward along the equipment edge within 3-6 hours post-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 gravel-type 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 aggregate reinforced grouting material to ensure the grouting construction.
Step 5: Maintenance
Within 30 minutes after grouting is completed, immediately cover with a wet straw blanket or mineral wool blanket and keep it moist.
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 and Environmental Temperature Relationship Chart" for the specific time.
4. After the equipment foundation grouting is completed, if there is a need to remove any parts, gently scrape them off with a trowel 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. The machine should be shut down for 24-36 hours after secondary grouting to prevent damage to the unhardened grouting layer.
