With In this paper, four grouting materials, namely new type grouting material, pure cement, cement-sodium silicate and glue sand, were tested by single factor for their water corrosion resistance, permeability resistance and volume stability. The durability of the four grouting materials under the environment of three factors was evaluated by the multi-factor fuzzy comprehensive evaluation method. The results show that the three kinds of new type grouting materials are better than the other three kinds of grouting materials in terms of anti-water corrosion and volume stability. In terms of impermeability, the performance of cement reached the best impermeability pressure of 0.8Mpa, but the impermeability pressure of new type grouting material with a water-cement ratio of 1.0 has also reached 0.6MPa, which can meet the impermeability requirement with a small gap with cement. As a scientific and effective evaluation method, the method will be helpful to the further study of the durability of grouting materials.
