The invention relates to a grouting material. The grouting material is prepared from the following raw materials in parts by weight: 12-25 parts of sulphate aluminium cement, 4-8 parts of anti-sedimentation agent, 5-18 parts of steel slag, 12-17 parts of semi-rigid material, 10-20 parts of natural sodium bentonite, 14-19 parts of gravels, 20-25 parts of quartz sand, 2-4 parts of anhydrous gypsum powder, 0.5-1.5 parts of sodium chloride, 6-9 parts of aluminate cement, 4-7 parts of CSA expanding agent, 0.6-1.1 parts of calcium formate, 5-8 parts of gypsum and 0.1-0.2 part of water-retaining agent. The grouting material disclosed by the invention has the beneficial effects that the grouting material has good self-flowing property, rapid hardening property, early strength and high strength, and the engineering safety and the durability are improved.
