Micro-expansion high-strength offshore wind power grouting material and preparation method thereof
The invention discloses a micro-expansion high-strength offshore wind power grouting material and a preparation method thereof, the micro-expansion high-strength offshore wind power grouting material comprises superfine cement, fine aggregate, micro-nano powder, an expansion component, a microcapsule plastic expansion agent and a water reducing agent, and the microcapsule plastic expansion agent is composed of a calcium carbide core material and an organic silicon resin wall material; during preparation, the superfine cement, the fine aggregate, the micro-nano powder and the expansion component are mixed and stirred to prepare powder A, then the microcapsule plastic expanding agent and the water reducing agent are mixed and stirred to prepare powder B, and finally the powder A and the powder B are mixed and stirred to prepare the micro-expansion high-strength offshore wind power grouting material. The grouting material has the advantages of higher flowability, easiness in construction, ultrahigh strength, micro-expansion and no shrinkage in the later stage, and can be used for grouting of offshore wind power foundations.
本发明公开了一种微膨高强海上风电灌浆料及其制备方法，包括超细水泥、细集料、微纳粉体、膨胀组分、微胶囊塑性膨胀剂及减水剂，而微胶囊塑性膨胀剂由碳化钙芯材和有机硅树脂壁材构成；制备时先将超细水泥、细集料、微纳粉体和膨胀组分混合搅拌制得粉料A，再将微胶囊塑性膨胀剂和减水剂混合搅拌制得粉料B，最后将粉料A和粉料B混合搅拌，制得微膨高强海上风电灌浆料。该灌浆料具有较高的流动性，易于施工，超高强度及微膨胀，后期无收缩，可用于海上风电基础的灌浆。
