Curing time adjustable two-component grouting liquid
The invention relates to the related field of grouting liquid, in particular to curing time adjustable two-component grouting liquid which comprises, by mass, 40-50% of medium sand, 20-30% of cement;3-4% of a composite stabilizer; 3-4% of a modifier; 2-3% of a waterproof agent; 2-3% of a water reducing agent; 4-5% of an antifreezing agent; 4-8% of a curing agent; 10-20% of water; according to thepresent invention, the composite stabilizer is prepared from cellulose ether, butyl acrylate and polymethyltriethoxysilane according to the ratio of 1: 1: 1 so as to effectively ensure the overall strength of the molded mortar, and the anti-freezing agent prepared from calcium chloride and calcium nitrite according to the ratio of 2: 1 is added to the mortar, the anti-freezing performance of thegrouting liquid after solidification is effectively improved, and the curing agent prepared from calcium aluminate and calcium fluoroaluminate according to the ratio of 1: 1 is added into the groutingliquid so that the overall solidification efficiency of the grouting liquid is improved under the action of the calcium aluminate and the calcium fluoroaluminate, and the situation that the solidification efficiency of the grouting liquid is low, and then, the next procedure in the project is influenced can be avoided.
本发明涉及注浆液相关领域，具体为一种固化时间可调式双组份注浆液，包括（按质量百分比计）：中砂40‑50%；水泥20‑30%；复合稳定剂3‑4%；改性剂3‑4%；防水剂2‑3%；减水剂2‑3%；防冻剂4‑5%；固化剂4‑8%；水10‑20%；本发明的配方通过采用纤维素醚、丙烯酸丁酯和聚甲基三乙氧基硅烷三者以1：1：1进行配比制成的复合稳定剂，从而有效保证其成型后的整体强度，并通过在砂浆中添加用氯化钙、亚硝酸钙以2:1进行配比制成的防冻剂，从而有效提高其注浆液在凝固后的抗冻性能，并通过在注浆液中添加用铝酸钙、氟铝酸钙以1:1进行配比制成的固化剂，从而通过铝酸钙、氟铝酸钙的作用来提高注浆液的整体凝固效率，从而避免注浆液的凝固效率较慢，从而影响到工程中下一步工序的进行。
