The effects of xenon lamp and wear on the waterproofing effect of silicone emulsion were investigated. The results show that the surface impregnated treatment with silicone resin on concrete can improve the hydrophobicity of concrete, and reduce the capillary water absorption of concrete, and the effect becomes dominant with the increase of coating amount. After 90-d xenon lamp test, the contact angle of the surface impregnated concrete and the water absorption curve of the surface impregnated concrete do not change much. The surface impregnated concrete after aging still shows a good hydrophobicity. The existence of the main chain of Si-O-Si leads to a good aging resistance of silicone resin. The hydrophobicity of surface impregnated concrete with silicone resin decreases gradually with the increase of worn depth.
