Special high strength grouting material for connecting reinforcement sleeve
The present invention discloses a special high strength grouting material for connecting a reinforcement sleeve. The special high strength grouting material for connecting the reinforcement sleeve comprises grouting material powder and water, wherein the grouting material powder is prepared from the following raw materials in percentage by weight: 45% to 50% of cement, 0.1% to 0.3% of a water reducing agent, 0.06% to 0.1% of a defoamer, 1% to 3% of a water retention tackifier, 0.025% to 0.05% of a composite retarder, 1% to 2% of a composite expansion agent; and and the balance of quartz sand, totalling 100, wherein the mass ratio of the grouting material powder to the water is 1 to (0.23-0.28). The special high strength grouting material for the connecting reinforcement sleeve provided by the present invention has the characteristics of high strength, high adhesion and slight expansion with no shrinkage; the high strength grouting material can be poured into the reinforcement sleeve to enable fixed connection formed between reinforcements and between the reinforcements and the sleeve, and has excellent durability.
