Abstract

The previously-published one-dimensional finite element model for the analysis of the carbonation mechanism is extended to two-dimensional problems. The governing equations for the propagation of aggressive agents through concrete are rewritten for two-dimensional domains. A comparison is made with the one-dimensional model and some examples are developed to test the method. Finally, the study of a reinforcing bar placed at the corner of a concrete structure is presented in detail to show that the proposed numerical model is able to demonstrate the effects of the multidimensional moisture, heat and carbon dioxide transport through concrete
