| Abstract: | The investigation of deterioration of railway reinforced concrete beams in arid region was executed.It was the wetting and drying at cover to reinforcement of concrete beams which caused corrosion and cracking.The result of corrosion tests shows that wetting and drying at cover to reinforcement can accelerate the rate of corrosion of steel.The suggestion of improving standard design of drainage construction for and repairing method for existing beams is also put forward in this paper. |
