| Abstract: | A method is presented for the determination of the diffusion coefficient of water in brick. A brick is sealed on five sides to ensure one-dimensional water transport. The wet brick is hung with the utmost ends each from a balance. This way, not only the mass of the water in the brick is measured, but some information is obtained about the mass distribution inside the brick. The brick used in this study appears to be quite inhomogeneous. This is incorporated in the model with an inhomogeneity constant. It needs further research if this parameter depends on the water concentration in the brick. |
