This paper examined the mechanical property of rubber mortars with different amount of rubber granules addition and the influence of fly ash, slag and silica fume. The increase of rubber granules results in the decrease in compressive and flexural strength of rubber mortar, but increases the ratio of flexural to compressive strength. The fly ash, slag and silica fume are useful for improving the mechanical property of mortar. The examined contact angle of water against rubber is 99.5°, which suggests the rubber surface is hydrophobic, and the hydrophobic surface interprets the weak interface between rubber and cement matrix.
