A disclosed underwater non-dispersible grouting material comprises an external additive and concrete. The external additive comprises an adhesive, a water reducing agent, a thickening agent and a coagulant. The adhesive accounts for 1%-2.5% of the specific gravity of the grouting material, and the adhesive is redispersible latex powder. The water reducing agent accounts for 0.75%-2.5% of the grouting material, and the water reducing agent is a naphthalene-based high-efficiency water reducing agent. The thickening agent accounts for 1%-2% of the grouting material, the thickening agent is one or two of hydroxy propyl cellulose and carboxymethyl cellulose, and the viscosity of the thickening agent is 34 thousand viscosity. The coagulant accounts for 3.0%-10% of the grouting material, and the coagulant is polyaluminum chloride. According to the invention, the concrete can be prevented from being dispersed by flushing or being mixed with water to cause aggregate dispersion during underwater construction, so that the water resistance of the slurry is improved.
本发明公开了水下不分散注浆料，包括外添加剂和混凝土，所述外添加剂成分包括：粘合剂、减水剂、增稠剂和混凝剂；所述粘合剂，占注浆料比重为1％‑2.5％，所述粘合剂为可再分散乳胶粉；所述减水剂，占注浆料的比重为0.75％‑2.5％，所述减水剂为萘系高效减水剂；所述增稠剂，占注浆料的比重为1％‑2％，所述增稠剂为羟丙基纤维素和羧甲基纤维素中的一种或者两种，所述增稠剂的粘度为3.4万粘度；所述混凝剂，占注浆料的比重为3.0％‑10％，所述混凝剂为聚合氯化铝。本发明可抑制混凝土在水下施工时被冲数或水混和骨料分散，从而提高浆料水中抗分性能。
