The influence of sorption hysteresis on diffusion coefficients represented with different moisture potentials
Författare
Summary, in English
This paper continues the discussion in a previous paper [Saeidpour and Wadsö doi:10.1016/j.cemconres.2016.02.003] where a clear effect of sorption hysteresis was seen in moisture diffusion coefficients for cement-based materials. Coefficients with vapor content as potential (Dv) had different values depending on whether the sample was in absorption or in desorption. In this paper we recalculate these Dv coefficients into coefficients with other potentials and draw them as a function of different potentials. The aim is to see if the effect of hysteresis disappears with an optimal choice of representation. The best choice was to draw Dv is as a function of the degree of saturation (concentration, moisture content).
