Use of high durable underwater non-dispersible concrete flocculant

The invention discloses a use of a durable underwater non-dispersible concrete flocculant. A preparation method of the durable underwater non-dispersible concrete flocculant comprises mixing and grinding cement, a high performance water reducer, metakaolin, microsilica fume, silicon carbide sand activated carbon, finely ground ore powder and a flocculant according to a certain ratio and carrying out detection through the DLT 5117-2000 Underwater Dispersion Concrete Test Regulations. The durable underwater non-dispersible concrete flocculant has high curing efficiency, good hardening strength,a high water reduction rate of 20% and good concrete cohesiveness, is easy to stir, has good anti-freezing durability, is conducive to the construction of large-volume concrete, significantly reducesconcrete shrinkage, has good product stability, prevents layering in long-term storage and prevents precipitation phenomenon. 本发明公开种耐久性的水下不分散混凝土絮凝剂的应用，其通过水泥、高性能减水剂、偏高岭土和微硅粉硅灰、碳化硅砂活性炭和磨细矿粉、絮凝剂按照定比例混合磨碎制得。最后采用DLT 5117-2000《水下不分散
