With the promotion of prefabricated building by the state, a large number of building parts are prefabricated in workshops, and all parts are connected by sleeve grouting. The quality of the grouting material determines the safety of the connection, therefore, it is of great significance to develop grouting materials with excellent properties. Using portland cement and adding other components such as ground sand, super plasticizer and expansion agent to improve the workability and mechanical properties of grout, the non-shrinkage sleeve grouting material with excellent properties of early strength and micro-expansion was prepared. The results show that: portland cement 77.7%, fine sand 20%, silica fume 2.3%, water reducing agent 0.43%, expansion agent 2.0%, plastic expansion agent 0.07%, mortar ratio 1:1, water to material ratio 0.11, initial fluidity 310 mm, 30 min fluidity 290 mm, the compressive strength of 1, 3, 28 d is 49.1, 63.3, 91.9 MPa respectively, the expansion rate of 3 h is 0.24%, the expansion rate of 24~3 h is 0.37%, which meets the requirements of "Sleeve grouting material for steel bar connection".
