The electrical and mechanical behaviours of marble and cement mortar samples and the differences between them were studied by subjecting them to uniaxial compression. The Pressure Stimulated Current (PSC) technique was applied to measure the charge released by uniaxially compressed samples under constant stress rate up to their failure. As far as the PSC emission is concerned in both marble and cement mortar samples, similar behaviours are observed. They only differ quantitatively, cement mortar giving higher pressure stimulated current density values.
