Product Description
The CGM-100 wind turbine foundation grouting material is a shrinkage-free, high-strength grouting material specifically designed for the bases of megawatt-class wind turbines. It features a composite formulation combining ultrafine cement with high-performance polymers, enabling it to withstand the long-term dynamic loads generated during wind turbine operation and ensuring a rigid connection between the tower and the foundation.
3. Application Scenarios and Features
Application scenarios Features: 1. Installation of onshore wind farm tower foundation 1. Ultra-high strength 2. Anchor bolting for offshore wind turbine foundations 2. Micro-expanding self-leveling 3. Reinforcement of the foundation structure of aging airfields 3. High elastic modulus 4. Seismic and Impact Resistance Protection Against Extreme Weather Conditions 4. Low-temperature resistance 5. Hybrid-based corrosion-resistant and durable protection 5. Chloride-free 
4. Technical Specifications: Performance Assurance in Extreme Environments Key parameters: Compressive strength (1 day > 30 MPa, 3 days ≥ 50 MPa, 28 days > 100 MPa), vertical expansion rate (≥ 0.02%), flowability (initial > 340 mm, 30 min > 320 mm), freeze-thaw resistance grade (F300), and modulus of elasticity (28 days > 3.0 × 10⁴ MPa).
Structural safety throughout the entire lifecycle
Onshore wind power: Secondary grouting of turbine foundations for wind farms in mountainous and plain areas;
Offshore wind power: Connection between the jacket foundation and the support structure of offshore wind turbines in the intertidal zone and nearshore areas;
Old wind turbine retrofit: Reinforcement of existing foundations and upgrade of load capacity, compatible with 2.5 MW to 6 MW models.
5. Functional Features: Three Major Technological Breakthroughs
1. Micro-expansion compensation: The non-shrinking property ensures 100% contact between the grouting layer and the base, preventing voids.
2. Dynamic Load Adaptation: The elastic modulus is matched to the wind turbine’s steel structure to absorb operational vibrations.
3. Compatible with low-temperature construction: Can be applied in environments as low as -10℃; the addition of antifreeze components does not affect the later strength.
6. Instructions for Use: Standardized Construction Process
1. Base preparation: Roughen the concrete surface, install formwork and apply release agent, and use compressed air to remove dust.
2. Material Preparation: Mix the materials with a water-to-material ratio of 1:8.5 and mechanically stir for 3–5 minutes to ensure there are no granular particles remaining.
3. Continuous grouting: Allow the grout to flow freely from one side to the other, with a height exceeding the anchor bolts by 50 mm, and vibrate thoroughly to ensure compaction.
4. Maintenance: Cover with moisture-retaining cotton. In summer, water regularly for 7 days; in winter, use an electric heating blanket for insulation and maintenance.
7. Construction Scenarios
Next, we’ll play a video of the construction site, showcasing the entire process—from foundation preparation to grouting completion. The video highlights key procedures such as mechanical mixing, continuous pouring, and vibration compaction, emphasizing the product’s ease of construction and on-site adaptability.
