The invention discloses a modified grouting material. The grouting material is prepared from raw materials in parts by weight as follows: 55-65 parts of portland cement, 10-15 parts of aluminate cement, 6-9 parts of a polymer emulsion, 25-35 parts of a mineral additive, 0.1-0.3 parts of a foam stabilizer, 4-8 parts of an activator, 0.1-0.3 parts of a water-retaining agent, 0.2-0.4 parts of a surfactant, 2-4 parts of bentonite, 0.2-0.6 parts of fine sand, 0.2-0.6 parts of sodium carbonate, 0.02-0.04 parts of ceramic fiber, 0.01-0.03 parts of emulsion powder, 0.02-0.04 parts of dolomite, 0.01-0.03 parts of pyrophyllite and 6-8 parts of methyl sodium silicate. Flexibility of polymer and rigidness of the mineral additive are jointly used for modification, the grouting material with excellent performance is obtained, and the application range is enlarged.
