The invention discloses durable grouting material. The grouting material is prepared from the following raw materials in parts by weight: 50 to 70 parts of portland cement, 15 to 25 parts of aluminate cement, 4 to 8 parts of polymer emulsion, 20 to 40 parts of mineral additives, 0.1 to 0.3 parts of defoaming stabilizer, 6 to 9 parts of stimulator, 0.1 to 0.3 parts of water retaining agent, 0.3 to 0.5 parts of surfactant, 1 to 5 parts of bentonite, 0.3 to 0.7 parts of fine sand, 0.2 to 0.6 parts of sodium carbonate, 0.03 to 0.07 parts of ceramic fiber, 0.01 to 0.03 parts of emulsion powder, 0.02 to 0.04 parts of dolomite, 0.01 to 0.03 parts of pyrophyllite and 2 to 6 parts of methyl sodium silicate. According to the durable grouting material, a polymer and the mineral additives are modified together by utilizing the flexibility of the polymer and the rigidity of the mineral additives, so that the grouting material with good performance is obtained, and an application range of the grouting material is enlarged.
