Analysis and Comparison of Calculation Method of Concrete Carbonation of Reinforced Concrete Bridges

Forecasting of concrete carbonation depth is an important part of the structural durability assessment.This article discusses the mechanism and factors of concrete carbonation of the reinforced concrete structures,and sums up a few models of concrete carbonation depth.Taking an actual bridge as an example,we can find out the reasonable models,then calculate how long the forefront of concrete carbonation will get to the surface of the steel bar in use of the reasonable models we find out.
