ABSTRACT

An inverse analysis of coupled water and salt transport in porous materials is presented in the paper. For the description of salt solution transport, the diffusion-advection model taking into account the influence of water movement on salt transport and the salt bonding on pore walls is used. The inverse analysis is performed for the samples of cement mortar. As a result, moisture diffusivity as function of moisture content and chloride diffusion coefficient as function of concentration are obtained.
