Popis:	U radu su prikazani i analizirani rezultati ispitivanja karakteristika zračnih pora u svježem i očvrsnulom betonu. U svježem betonu ispitivanja su provedena tlačnom metodom pomoću porometra i analizom zračnih pora uređajem Air void analyzer. Na očvrsnulom betonu pore su analizirane mikroskopskom analizom, uređajem pod nazivom RapidAir 457. Mjerene karakteristike zračnih pora su: ukupna količina, faktor razmaka i specifična površina. Uspoređeni su rezultati iz dva laboratorija. Results obtained by testing properties of air voids in fresh and hardened concrete are presented and analysed. In fresh concrete, the testing was conducted by compression using porometer and by air void analysis using the air void analyser. The voids in hardened concrete were analyzed through microscopic analysis using the device called the RapidAir 457. The following properties of air voids were measured: total quantity, spacing factor and specific area. The results obtained by two laboratories were then compared.
