The specific surface area of each clay type and Ottawa sand was determined by nitrogen-gas-adsorption Brunauer–Emmett–Teller method. We also calculated the porosity and saturation of each mixture based on weight loss of dried samples. Debye decomposition, a phenomenological model, was applied to ...
