In this paper, the same consistency of eolian sand mortar was prepared by blending polypropylene fibers of 0, 0.3Kg/m3, 0.7Kg/m3, l.0Kg/m3, 1.3Kg/m3 and 1.8Kg/m3 respectively. Effects of fiber content on physical properties such as shrinkage, strength and crack resistance of aeolian sand dry mortar. The results show that polypropylene fiber can significantly improve the physical and mechanical properties of aeolian sand dry mortar. Polypropylene fiber content is within 1,3Kg/m3, and with the increase of fiber content, the effect of aeolian sand mortar is obvious; when the content exceeds 1.3Kg/m , the shrinkage and mechanical properties are shrunk; the wind and sand accumulation mortar is aggregated. The suitable amount of propylene fiber is 1.3Kg/m . Under this dosage, polypropylene fiber can not only improve the construction performance of aeolian sand mortar, but also improve its basic mechanical properties.
