Abstract：Based on the principle of alkali activated cementitious materials,a new type of green grouting material was prepared by using steel slag and grounded furnace slag as the main raw material. In a fixed modulus of water glass,alkali equivalent(10％ or 12％),the ratio of water to solid and the amount of admixture,the effect of steel slag content on the fluidity, setting time,consolidation strength and drying shrinkage of the grouting material was studied. The test results showed that when the equivalent of alkali is 12％ and the amount of steel slag is 30％,the maximum of initial fluidity is 290 mm,and the minimum of 30 min fluidity retention value is 148 mm;when the equivalent of alkali is 12％ and the amount of steel slag is 40％,the shortest setting time is 91 min,when the equivalent of alkali is 10％ and the amount of steel slag is 40％,the maximum of consolidation strength value is 54.6 MPa,when the amount of steel slag is in 30％～70％,the increase of steel slag content can significantly improve the dry shrinkage performance of the grouting material.
