Wind power grouting material, preparation method and application thereof
By leveraging the synergistic effect of a gradient cementing system and a composite expanding agent, combined with a stepwise fiber-reinforcing process and nano-microstructure early-strength crystal nuclei, the comprehensive performance problem of wind power grouting materials in complex environments has been solved. This has resulted in a wind power grouting material with high flowability, ultra-high strength, and fatigue resistance, suitable for grouting construction of wind power foundations and key offshore components.

AI Technical Summary
Existing cement-based non-shrink grouting materials for wind power suffer from problems such as insufficient flexural strength and fracture toughness, uneven fiber agglomeration and dispersion, decreased fluidity, early plastic shrinkage or late shrinkage under complex service environments, making it difficult to meet the comprehensive performance requirements of long-term service conditions for offshore wind power.
By employing a gradient cementing system, composite expansion agent, stepwise fiber addition process, and nano-microstructure early strength crystal nuclei, a wind power grouting material with high flowability, self-compacting properties, full-process micro-expansion, ultra-high strength, high toughness, and salt corrosion resistance is constructed. Through the synergistic combination of silica fume, fly ash, graded quartz sand, and copper-plated microfiber steel, uniform dispersion and full-process shrinkage compensation of the material are achieved.
It achieves synergistic optimization of high fluidity, ultra-high strength, fatigue resistance and salt corrosion resistance, and is suitable for wind power foundations, tower flanges, jacket nodes and offshore anchoring foundations, improving the long-term safety and service life of the structure.
