Role of Time Relaxation in a One-Dimensional Diffusion-Advection Model of Water and Salt Transport
Original language description
The transport of salt, necessarily coupled with the transport of water, through porous building materials may heavily limit their durability due to possible deterioration and structural damage. Usually, the binding of salt to the pore walls is assumed tooccur instantly, as soon as the salt is transported by water to a given position.We consider the advection-diffusionmodel of the transport and generalize it to include possible delays in the binding. Applying the Boltzmann-Matano method, we calculate the diffusion coefficient of the salt in dependence on the salt concentration and show that it increases with the rate of binding. We apply our results to an example of the chloride transport in a lime plaster.
