Characterization of the mechanical damage of a chemically degraded cement paste
Abstract Cement-based materials as concrete interact with their environment. In the presence of aqueous mediums, dissolutions and precipitations of solid species composing the cement paste induce a chemical damage, which may affect the structure integrity. This paper presents a mechanical characterization of the Young modulus evolution of chemically damaged cement paste, based on a microstructural approach coupled to a reactive-transport model. The method has been successfully applied to cement pastes leached by pure water. It is concluded that the capillary porosity and its spatial distribution within the material are the parameters, which mainly rule the stiffness evolution.
