Abstract

Cement-based materials in aqueous environments are subjected to evolutions that concern both the solid skeleton and the pore solution of the cement paste. Moreover these two elements strongly interact themselves. A physico-chemical approach is developed to represent these interactions within a cement paste. A finite-element model supplements this approach and evaluates mechanical properties of a chemically degraded cement paste. This approach is successfully applied to a pure water leaching and represents its influence on the Young modulus of a cement paste.
