Test samples of cylindrical shape (Ø=15 mm, h=15 mm) produced using dry pressing and consisting of different clay, sand and glass granulate mixtures were activated using the electric field of a corona discharge and subsequently fired at different temperatures (700-900°C). Depending on the strength of the activating electric field, the duration of the activation process and the firing temperature a substantial increase in the mechanical strength with respect to the non-activated reference samples was observed.
