15101060180 | Song Manager – Grouting Material Manufacturer, Grouting Price, Grouting Standard, Direct Sales, Beijing Grouting Material Supplier. As the country's largest producer and supplier of grouting materials, our products are known for their high quality, performance, and reliability.
**Product Features**
1. **Early Strength & High Strength**: Achieve a compressive strength of ≥20MPa in 1 day, ≥30MPa in 3 days, and ≥55MPa in 28 days.
2. **Micro-Expansion**: Ensures tight contact between equipment and foundation, eliminating shrinkage after secondary grouting.
3. **High Self-Flow**: Easily fills all gaps, meeting the requirements of equipment secondary grouting.
4. **Anti-Segregation**: Prevents separation caused by excess water during on-site use.
5. **Anti-Cracking**: Resists cracking due to improper water addition or temperature fluctuations.
6. **Durable**: Maintains strength after 50 freeze-thaw cycles and shows significant improvement after 30 days of oil soaking.
7. **Winter Construction**: Can be used at temperatures as low as -10°C.
**Applications**
- Secondary grouting for equipment foundations
- Anchoring of anchor bolts and reinforcement steel
- Repair and reinforcement of concrete structures
**Beijing CGM High-Strength Non-Shrinkage Grouting Material**
This second-generation inorganic material is an upgraded version of CGM grouting materials, developed based on years of practical application.
**Key Features**
- **Early Strength & High Strength**: Compressive strength reaches 30–50MPa within 1–3 days.
- **High Self-Flow**: Fills all gaps effectively for proper secondary grouting.
- **Micro-Expansion**: Ensures strong bonding with no shrinkage, with bond strength ≥6MPa.
- **Winter Construction**: Suitable for outdoor use at -10°C.
- **Long-Lasting**: With a service life exceeding that of the base concrete, it maintains stability even after 50 freeze-thaw cycles and improves strength after 30 days of oil exposure.
**Usage Scenarios**
- Secondary grouting for machine bases, anchor bolts, and other equipment
- Reinforcement and repair of beams, slabs, columns, foundations, floors, and roads
- Anchoring and structural reinforcement of anchor bolts and steel bars

| Reinforced bond strength (MPa) | ≥6 | ≥6 | ≥6 | — |
| Maximum aggregate size | 6–8 mesh | Bean stone | 20–38 mesh | 6–8 mesh |
**Notes**
- Compressive strength tested according to GB177-85.
- Expansion rate tested according to GB119-88.
- For grouting layers ≥150mm, choose HGM-1 or HGM-2.
- For grouting layers <30mm, refer to the curing time chart below:
| Ambient Temperature (°C) | Demoulding Time (h) | Curing Time (h) |
|--------------------------|---------------------|------------------|
| -10～0 | 96 | 14 |
| 0～5 | 72 | 10 |
| 5～15 | 48 | 7 |
| ≥15 | 24 | 7 |
**Construction Steps**
1. Prepare mixing equipment, grouting tools, formwork, and maintenance materials. Clean and wet the surface before grouting.
2. Set up the formwork and seal the joints with cement mortar or plastic tape to prevent leakage.
3. Add 12–15% water by weight and mix thoroughly (mechanical stirring for 2–3 minutes, manual stirring for 5+ minutes).
4. Pour the mixed grout from one side. Use bamboo strips or steel bars if needed, and gently vibrate or tap the formwork.
5. After completion, apply a curing agent or cover with plastic film and straw mats for 3–7 days.
6. Work within a temperature range of -10°C to 40°C. Do not add any external admixtures.
**Packaging & Transportation**
- Packaged in 50kg bags. Store in dry, ventilated areas away from direct sunlight.
- Shelf life is 3 months; retest before use if stored longer.
