Study on Mechanical Properties and Mechanism of Sisal Fiber Cement Mortar

This paper comparatively study on fluidity, flexural strength, compressive strength and other mechanical properties of sisal fiber cement mortar and the base mortar. The results show that fluidity of sisal fiber makes sisal fiber cement mortar than that of the base group decreased about by 11.1%;When sisal fiber content is 4.5 kg/m3, water reducing agent is 2.78 kg/m3, the best mixing proportion of sisal fiber cement mortar for water: glue: sand = 0.45:1.:2.5, flexural strength improved by 52.4%, 54.3%, 20.1% respectively, compressive strength increased by-1.5%, 6.5% and-2.1%.And analyzed the mechanism of flexural and compressive from the chemistry of sisal fiber and cement.
