High-impermeability maritime work cement, preparation method thereof, concrete and application

The invention provides high-impermeability maritime work cement and a preparation method thereof, concrete and application, and relates to the technical field of ocean engineering. The high-impermeability maritime work cement is prepared from cement clinker, gypsum, fly ash, first ceramic polishing waste and superfine slag micro powder; wherein the superfine slag micro-powder comprises superfine powder obtained by mixing and grinding second ceramic polishing waste, wet-discharged coal slag and slag. The technical problems that maritime work cement is low in early strength, high in later shrinkage rate and poor in impermeability and abrasion resistance are solved, and the technical effect that the impermeability and the corrosion resistance are greatly improved on the premise that the high cement strength is guaranteed is achieved. 本发明提供了一种高抗渗海工水泥及其制备方法、混凝土、应用，涉及海洋工程的技术领域，本发明的高抗渗海工水泥包括水泥熟料、石膏、粉煤灰、第一陶瓷抛光废料以及超细矿渣微粉；其中的超细矿渣微粉包括第二陶瓷抛光废料、湿排煤渣以及矿渣混合研磨得到的超细粉体。本发明解决了海工水泥早期强度不高，后期收缩率较高，而且抗渗性和耐磨性较差的技术问题，达到了在保证较高水泥强度的前提下
