Abstract：Through the experimental analysis of the influence of cement sand ratio,metakaolin,water reducing agent and ex-pansion agent on the sleeve grouting material fluidity,strength and expansion rate,determine the optimal cement sand ratio of sleeve grouting material was 5:5,adding 3.0％ metakaolin can significantly improve the later-stage strength of the sleeve grouting material,the content of water reducing agent and expansion agent were 0.30％ and 10.0％ of cementitious materials,respectively,to improve the sleeve grouting material fluidity and expansion rate,forming the best fit sleeve grouting material ratio,and according to the standard JGJ 355—2015 to test the mechanical properties of steel half sleeve grouting joint,and the application effect of the sleeve grouting material was evaluated.
