| Abstract: | Carbonation reaction can accelerate the corrosion of steel bar and reduce the service life of reinforce concrete.The problem of carbonation reaction has been thus an interesting aspect in fields of civil engineering materials.The existing models were classified and the latest theoretical models were reviewed.Also,the latest model parameters(i.e.,transport coefficient of CO2,porosity,satura-tion,chemical reaction rate,pH value and carbonation depth,etc.) were analyzed in details.In addition,the solving methods of theo-retical models and the corresponding further studies were proposed. |
