In order to improve the durability of bridge concrete,this paper proposes three anti-corrosion treatment schemes based on the introduction of anti-corrosion methods of bridge concrete,and evaluates their anti-corrosion effects.The results show that the anti-corrosion schemes of polymer mortar,silane impregnation and composite anti-corrosion can all achieve the anti-corrosion function.After 4 days of water immersion and 100 times of rapid freeze-thaw cycles,the water seepage depth and mass loss rate of the concrete specimens treated with polymer mortar and composite anti-corrosion scheme were significantly lower than those of the silane impregnation group,indicating that the anti-corrosion performance of the two schemes was better than that of silane impregnation.
