The main goal of this paper is to describe the mechanical behavior of the CDW recycled concrete in\ncompression, using an isotropic damage model adapted to the variation of the replacement rate of\nnatural aggregates by recycled ones. The isotropic model by Mazars was used as a constitutive\nequation for the CDW concrete and its adjustment parameters, A and B, were written as quadratic\npolynomials according to the aggregates replacement rate. The model was evaluated for conventional\nand recycled concretes. For the latter ones, the aggregates replacement ratios evaluated\nwere 50% and 100%. The results show good approximation between the analytical and numerical\nvalues obtained with the adapted isotropic damage model and experimental concrete results for\nboth compressive and flexural strength.
