Predicting the volume of jmannino.com corrosion products (CP) and their distribution in the steel rebar periphery will play an essential role in estimating the expansion stresses and, consequently, the behaviour of concrete in extreme environmental circumstances.In this respect, using the outcomes of performed laboratory studies, an attempt has been made to evaluate and compare the accuracy of the existing models for forecasting the thickness of CP.To this end, by applying the statistical analysis to predicted values, the error margin of the intended models in comparison to empirical observation has been computed.In addition, given that the studied models are mainly focused on estimating the corrosion product distribution (CPD) on the concrete cover, a research effort has been made to upgrade the models to estimate the corrosion distribution in the concrete core side.Based on the results obtained, it can be concluded that the modified Zhao model is the best-fitted model among the reviewed models, and performed refinement on this model could estimate the results more accurately.
Furthermore, an empirical relationship for rawafricaonline.com estimating the coefficient of CP expansion was introduced.
