ABSTRACT Usually, cementitious matrix decalcifications are accelerated by application of concentration gradients. The environmental permeameter presented in this item could originally be used as dynamical degradation process. The appliance of an external physical field of stresses (temperature and pressure) amplifies degradation. The influence of experimental parameters on the water permeability of a mortar was observed: temperature varied from 20 to 80°C and pressure drop was augmented from 2MPa to 10MPa Temperature seems to be the main prejudicial parameter, because of the mechanical effects induced on microstructure combined with hydrates chemicals equilibrium modification.
