A grouting material having durability is prepared from, by weight parts, 12-26 parts of river sand, 8-17 parts of water-soluble silicon dioxide, 7-14 parts of sodium formate, 10-16 parts of blast furnace granulated slag, 9-14 parts of high-performance expanding agent, 6-8 parts of slag reactive activator, 3-6 parts of high calcium powder, 0.1-0.2 part of lithium carbonate, 0.5-1.2 parts of FDN water reducing agent, 32-45 parts of portland cement, 0.2-0.3 part of lithium carbonate, 6-8 parts of gypsum, 22-26 parts of aggregate, 0.15-0.23 part of water-retaining agent and 0.04-0.05 part of retarder. The grouting material having durability has the advantages of good durability and flowing property, no shrinkage, high adhesive force, no cracking and no influence on the environment.
