Additional Information
Jiangxi Grouting Material, Nanchang Grouting Material Brand
CGM-1-Reinforced Grouting Material Grouting Material Production
I. Grouting Material Product Features
1. Early Strength, High Strength
1-day Compressive Strength ≥20 MPa; 3-day Compressive Strength ≥30 MPa; 28-day Compressive Strength ≥55 MPa
2. Micro-expansion
Ensures tight contact between equipment and foundation, with no shrinkage after secondary grouting.
3. High Fluidity
Fills all voids, meeting the requirements for secondary grouting of equipment.
4. Anti-segregation
Overcomes segregation phenomena caused by excessive water addition during on-site use.
5. Anti-cracking
Prevents cracking due to uncertain water addition, environmental temperature, and limited curing conditions during on-site use.
6. Strong Durability
After millions of fatigue tests and 50 freeze-thaw cycles, the strength shows no significant change. Strength significantly increases after 30 days of immersion in engine oil.
7. Suitable for Winter Construction
Allows outdoor construction at temperatures as low as -10°C.
II. Grouting Material Product Applications
1. For secondary grouting of equipment foundations.
2. For anchor bolts and embedded reinforcement.
3. For reinforcement and repair of concrete structures.
III. Test Characteristics
IV. Product Selection
1. When grouting layer thickness δ ≥150mm, choose CGM-1 or CGM-2;
2. When grouting layer thickness 30mm < δ <150mm, choose CGM-1 or CGM-2;
3. When grouting layer thickness δ ≤30mm, choose CGM-1 or CGM-3;
4. For rapid road repair, choose CGM-4.
V. Preparation Before Construction
1. Machine mixing: concrete mixer or mortar mixer;
2. Manual mixing: mixing trough and several shovels;
3. Several buckets;
4. Several platform scales;
5. Chute;
6. High-level funnel, grouting pipe, and pipe joints;
7. Grouting pusher;
8. Formwork (steel or wood formwork);
9. Straw mats, rock wool blankets, etc.;
10. Cotton yarn, adhesive tape;
VI. Grouting Construction Grouting Material
Step 1: Foundation Treatment
The foundation surface should be roughened. Clean the foundation surface, ensuring no debris such as gravel, floating slurry, dust, oil, or release agents. Moisten the foundation surface thoroughly 24 hours before grouting, and remove any accumulated water 1 hour before grouting.
Step 2: Formwork Setup
1. Set up formwork according to the grouting construction drawing. Seal joints between formwork and foundation, and between formwork pieces, with cement paste or adhesive tape to ensure the entire formwork is watertight.
2. Maintain a horizontal distance of about 100mm between the formwork and the equipment base to facilitate grouting construction.
3. The top of the formwork should be 50mm higher than the equipment base surface.
4. If grout leakage occurs during grouting, address it promptly.
Step 3: Grouting Material Preparation
1. For reinforced pea gravel type, mix with 13% standard water content.
2. Mechanical mixing is recommended, with a mixing time of 1-2 minutes (hand drill mixers are prohibited). For manual mixing, first add 2/3 of the water and mix for 2 minutes, then add the remaining water and mix until uniform.
3. The mixing quantity should be based on usage to ensure the material is used within 40 minutes.
4. Do not add any admixtures or additives to CGM-1 grouting material during on-site use.
Step 4: Grouting Construction Methods
1. For long equipment or track foundations, use segmented construction.
2. Diagrams of several common grouting methods
3. For secondary grouting, the following requirements should be met.
①. For secondary grouting, proceed from one side or multiple adjacent points until grout overflows from the opposite side to facilitate air expulsion during grouting. Do not grout from all four sides simultaneously.
②. Once grouting begins, it must be continuous without interruption, and the grouting time should be minimized.
③. Do not vibrate during grouting. If necessary, use a grouting pusher to move the CGM grout along the bottom of the grouting layer. Do not push from the middle or top of the grouting layer to ensure uniformity.
④. After grouting the equipment foundation, cut a 45-degree bevel outward from the equipment edge within 3-6 hours (see diagram below) to prevent cracking at the free end. If beveling is not possible, trowel the grouting layer surface smooth within 3-6 hours after grouting.
⑤. When the grouting layer thickness exceeds 150mm, use pea gravel reinforced high-strength non-shrink grout.
⑥. For large-volume equipment foundation grouting, use mechanical mixing for pea gravel reinforced grout to ensure construction quality.
Step 5: Grouting Material Curing
1. Within 30 minutes after grouting, cover with wet straw mats or rock wool blankets and keep moist.
2. For winter construction, curing measures should also comply with the current <>
