Grouting mortar CBGM

non-shrinkfor rebarcement

CBGM high-strength non shrinkage grouting material for wind power is mainly used for ultra-high strength cement-based grouting of onshore wind turbine. It is a non shrinkage cement-based grouting. After mixing with water, it produces uniform, flowable and pumpable grouting material with high early strength and final strength. The product has high fatigue resistance. The best cementitious material accumulation model and the grouting material produced under the guidance of cement nanotechnology have excellent technical properties, excellent rheological properties and unique ability to prolong the construction time. I. Product features 1. Ultra high compressive strength: exceeding the highest grade of EN206, such as C100/115. 2. Ultra high modulus for special hardening properties. 3. Excellent fatigue resistance. 4. The early strength develops rapidly and can be put into use quickly and the temporary support can be removed. 5. At 20 ℃ for 24 hours, ≥ 50MPa. 6. High flow state, no bleeding, anti-rust, ensure consistent final physical performance and prevent blocking of grouting pump. 7. It can be pumped for a long distance and height. 8. It can be pumped or injected into complex areas or areas difficult to access by conventional grouting methods. II. Scope of application 1. Grouting of wind turbine installations, i.e. installations installed using prestressing technology, such as foundation installation grouting of onshore wind turbines. 2. Equipment requiring excellent fatigue resistance. 3. Grouting is carried out under very harsh conditions, such as temperature as low as - 10 ℃. 4. Anchor the wind turbine tower bolts.
