The object of the research is ceramic material taken from the fortress wall of the city of Girona. The chemical composition of the test material showed an increased carbon content (13.1 & # 37;), which indicates the introduction of fuel into the raw material. The increased content of fuel in the raw material contributes to the formation of porosity and uniform sintering inside the ceramic specimen. Integral and differential porograms of the samples under study, obtained by the method of mercury porosimetry, showed that the total volume of micropores ranging in size from 10-4 to 10-8 m is 0.155 cm 3 / g. The differential distribution of micropores, depending on their size, is as follows: 10-4? 10-5 - 27 & # 37; (backup - non-hazardous); 10 ? 5 ? 10 ? 6 m - 19 & # 37; (dangerous); 10? 6? 10? 7 m? 29 & # 37 ;; 10? 7? 10? 8 m? 25 & # 37; (non-hazardous)
