High-strength ground repairing mortar
The invention provides a novel high-strength repair mortar. After a formula is optimized, the high-strength repair mortar with high initial setting speed, high initial strength and high self-sealing performance is obtained. The mortar is prepared from, by mass, 300-350 parts of ordinary portland cement, 200-250 parts of sulphoaluminate cement, 50-100 parts of coarse whiting (calcium carbonate), 350 parts of river sand, 1-5 parts of a retarder, 0.5-1 part of fibers, 1-2 parts of hydroxypropyl methyl cellulose, 20-25 parts of rubber powder, 0.5-0.8 part of an organic silicon defoamer, 0.5-0.8 part of an early strength agent, 60-80 parts of gypsum and 220-280 parts of water. The raw materials are weighed, and are stirred for 5 min in a forced physical stirring mode to obtain the slurry-shapedrepairing mortar.
本发明提供了一种新型的高强度修补砂浆，通过优化配方后得出初凝速度快且初始强度高，自密封性强的高强度修补砂浆，本申请砂浆包括了如下质量份的原料，普硅水泥300‑350份，硫铝水泥200‑250份，重钙(碳酸钙)50‑100份，河沙350份，缓凝剂1‑5份，纤维0.5‑1份，羟丙基甲基纤维素1‑2份，胶粉20‑25份，有机硅消泡剂0.5‑0.8份，早强剂0.5‑0.8份，石膏60‑80份，水220‑280份；上述原料在称取完成后，通过强制物理搅拌方式搅拌5min后，得到桨体状的修补砂浆。
