Abstract: The effects of NS particle size and content on the fresh mixing properties of silicate sulphoaluminate composite grouting materials are analyzed. The experimental results show that with the increase of NS content, the air content increases and the apparent density decreases, but the effect of NS particle size on air content and apparent density is the least. With the increase of NS content, the setting time of mortar decreases significantly; However, NS particle size has little effect on solidification time. The effect of fluidity on the mortar mixed with 30 particle size ns
