Abstract

Methods for determining the gas permeability of porous bodies are considered. The gas permeability of pressings from chamotte mixtures with different moisture contents and compositions is determined experimentally. The empirical dependence of the gas permeability of a pressed specimen on the pressing pressure is shown to have the form of a decreasing exponential. The parameters of the exponential are determined for various mixtures. Comparative curves of the gas permeability and the gas content are plotted in a wide range of pressing pressures.
