Ultrahigh-performance repairing grouting material for underwater construction as well as preparation method and application thereof
The invention relates to the technical field of cement-based building materials, in particular to an ultrahigh-performance repairing grouting material for underwater construction and a preparation method and application of the ultrahigh-performance repairing grouting material for underwater construction. Fast-setting and fast-hardening high-belite sulphoaluminate cement is adopted as a main cementing material, and a calcium aluminate amorphous phase is added to promote hydration; the ultra-fine fly ash, the ultra-fine mineral powder and the silica fume are added as auxiliary cementing materials to ensure the later strength of the repairing grouting material, and the repairing grouting material with ultra-high performance, which has the advantages of cracking resistance, high adhesion, ultra-high strength, underwater dispersion resistance and high durability, is prepared by matching with a compound additive.
本发明涉及水泥基建筑材料技术领域，尤其是涉及一种水下施工超高性能修补灌浆料及其制备方法与应用，采用快凝快硬高贝利特硫铝酸盐水泥作为主要胶凝材料，添加铝酸钙非晶相促进水化，添加超细粉煤灰、超细矿粉和硅灰作为辅助胶凝材料保证修补灌浆料后期强度，并配合复配外加剂，制备具有抗开裂、高粘接、超高强度、水下抗分散、高耐久性的超高性能修补灌浆料。
