Cementitious Grout for offshore TECHNICAL DATA wind power Used for grouting of ducts in offshore wind power stations DISCRIPTION 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 CONSTRUCTION PROCESS technical properties, excellent rheological properties and unique ability to prolong the construction time. PRODUCT HIGHLIGHT 1. Install the embedded parts of anchor plate according to the requirements of anchor bolt foundation drawing. 2. Weld the supporting bolts of the lower anchor plate firmly with the corresponding embedded parts, and 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. the height of the welding leg is ≤ 6mm. Adjust the supporting bolts so that the lower anchor plate reaches the design elevation of the drawing, the levelness of the lower anchor plate is ≤ 3mm, and the concentricity between the lower anchor plate and the Foundation Center is ≤ 5.0mm. 3. After the completion of concrete pouring, the top surface of the upper anchor plate shall be in a horizontal plane with an error of no more than 2mm. If the manufacturer has special requirements, it shall be implemented according to the manufacturer's requirements, and the installation error shall be 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. lower anchor plate, and the lower nuts shall be tightened to 300N.m . Do not omit. Before pouring the local 8. It can be pumped or injected into complex areas or areas difficult to access by conventional grouting cushion under the lower anchor plate, the concealed works shall be accepted. After the supervisor's acceptance, the external exposed wire buckle shall not be less than 2 buckles and shall be signed. Pouring After the anchor bolt penetrates into the lower anchor plate, all gaskets shall be padded under the can be carried out only after it is confirmed to be qualified (the nuts are not missing and tightened). 5. The concentricity of upper and lower anchor plates shall be ≤ 3mm. APPLICATION SCOPE 6. During concrete pouring, the anchor bolt assembly shall be mainly protected, and the upper anchor plate and the upper part of the anchor bolt shall be wrapped with plastic cloth or rain cloth to avoid 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. contamination or damage to the upper anchor plate and anchor bolt during concrete pouring. 7. Grouting construction can be carried out 3 days after the completion of main concrete pouring. The secondary grouting shall be free of shrinkage, bleeding, self leveling, non toxicity and anti-corrosion (rust) corrosion. The allowable deviation of grouting material thickness is ± 5mm, and the construction shall be continuous. The construction and maintenance of grouting materials shall be carried out in accordance with technical code for application of cement-based grouting materials GB/T50448-2015. 5. 25 mm to 30 mm void filling with high requirements for strength, modulus and ductility.
