Grouting material special for offshore wind power suction type foundation and preparation method of grouting material
The invention relates to the technical field of grouting materials, in particular to a grouting material special for an offshore wind power suction type foundation and a preparation method of the grouting material. The low-strength grouting material is prepared by taking cement, fly ash and mineral powder as main materials, adding additives with high fluidity, bleeding prevention, dispersion resistance, micro-expansion, segregation prevention and the like, and mixing and proportioning the above; the use amount of dry powder is reduced, the low-strength grouting material does not need aggregate, has the characteristics of high fluidity, no bleeding, no shrinkage, low strength, low density, no pollution, capability of being stirred by seawater and the like, can be used after a certain amount of seawater is added in a construction site and is uniformly stirred, and has the advantages of reliable quality, cost reduction, construction period shortening, convenience in use and the like in the aspect of construction.
本发明涉及灌浆材料技术领域，具体为一种海上风电吸力式基础专用灌浆材料及其制备方法，本发明提供的低强度灌浆料，以水泥、粉煤灰、矿粉为主材，添加高流动性、防泌水、抗分散、微膨胀、防离析等添加剂混合配比而成，减少干粉使用量，使本低强度灌浆料无需骨料且具有流动性高，无泌水、无收缩、低强度、低密度、无污染、可用海水搅拌等特点，同时在施工现场加入一定量的海水，搅拌均匀后即可使用，在施工方面具有质量可靠，降低成本，缩短工期和使用方便等优点。
