Researches on Concrete Carbonation

The cause and prevention of concrete carbonation are core issues in the engineering community. With the improvement of the global CO2 concentration, more and more reinforced concrete buildings are faced with the problems of carbonation acceleration and following threats of steel corrosion which will heavily undermine the safety and durability of R.C. structures. The article from three major aspects, Concrete carbonation mechanism, causes of carbonation and carbonation influences, reviews and summarizes the current researches on carbonation and proposes valuable suggestions.
