Abstract
ABSTRACT A rheological model with orthotropic short-time and long-time damage is developed in order to model leached concrete behaviour. Coupling with calcium leaching is obtained by affine attenuation of model parameters according to a microhardness profile measured on leached cement pastes. Calibration shows that most model parameters managing mechanical behaviour have the microhardness law as their attenuation law.
