According to the principle that fiber resist crack and cement-based capillary crystalline impermeability, the paper chose the mortar added with polypropylene fiber and SJ capillary crystalline material as the research object. Experiments on mechanical properties, crack resistance and impermeability of mortar were conducted with one material being added to the mortar as well as both materials being added to. The test results indicate that the ratio of compressive strength to flexural strength of mortar could be reduced, the time of cracks occurrence in mortar matrix would be delayed, and the minimum cracking coefficient can amount to 5% on the condition that the two materials are both added to the mortar, moreover, the mortar’s first and second impermeability is significant. Furthermore, the paper also discusses the mechanism of mortar’s crack resistance and impermeability which is mixed with polypropylene fiber and capillary crystalline material.
