The analysis of factors affecting the carbonation velocity of concrete protection layer by this paper, according to documents and engineering test data, the prediction of random model and carbonization of carbonization depth of life criterion proposed the general atmospheric environment protective layer of concrete railway bridges, and through the actual bridge test to validate the model.
The atmospheric pressure in the environment under the action of protective layer of concrete has accelerated carbonation trend. 2.2  Effects of concrete properties The compressive strength of concrete is a comprehensive index reflecting the performance of concrete, in general, the carbonation resistance of high strength concrete strength. [4] collected the data of literature at home and abroad investigation carbonization long-term exposure test and practical engineering of the 64 groups, through regression analysis, expression of the relationship between the compressive strength of concrete carbonation velocity coefficient and the atmospheric environment is proposed, i.e
The analysis of engineering example show that the model could reflect the basic law of the protective layer of concrete carbonation model required data acquisition, easy, simple and practical.
