AbstractThe effects of total porosity, average pore size, pore-size distribution and the size and density of crystallites are discussd in terms of the relationship between structure and mechanical properties. Several equations and their applicability are discussed. Pore reduction by impregnation is compared and the mechanism is explained in terms of the modification of stress concentrations and the filling of the pores. It is possible to predict mechanical properties using the mechanical characteristics corresponding to zero porosity as a basic parameter.
