Prediction of Moisture Diffusivity of Ceramic Bricks From Pore Size Distribution
Original language description
The Boltzmann-Matano method is a standard approach to determine the moisture diffusivity as a function of the moisture content. It is based on using the moisture profile whose measurement is a time consuming process. Alternatively, moisture transport parameters, including the moisture diffusivity, can be predicted from models that use pore distribution curves that are much easier to measure. In this paper we calculate the moisture diffusivity for two samples of a ceramic brick by both methods, using the Burdine model to determine the diffusivity from the pore curves. We then assess whether the approach using pore curves has the potential to become a reliable alternative for the prediction of varying moisture diffusivities of porous materials. We show that this might be a promising technique, although there are some problems that need to be resolved. Namely, the prediction of the diffusivity fails at low and large moisture contents. In addition, an independent determination of the diffusivity at a single value of the moisture content is required.
