Abstract

Leaching of a cement paste by a demineralized solution results in the progressive dissolution of the zone in contact with the aggressive solution. In the long term, this dissolution will determine the kinetics of degradation of the material. These kinetics will depend principally on the solubility of calcium in the zone in contact with the aggressive solution.
