Abstract

U radu je opisan postupak izrade uzoraka cementnog morta s različitim udjelima pepela iz biomase. U uzorke cementnog morta ugrađena je čelična armatura te je ispitivana osjetljivost čelične armature na koroziju. Opisana je metoda određivanja utjecaja osjetljivosti čelične armature potenciostatskim elektrokemijskim ispitivanjem prema HRN EN 480-14 te su prikazane posljedice utjecaja biopepela na osjetljivosti čelične armature na koroziju. Također, napravljena je usporedba ispitnih uzoraka, jednakog sastava i udjela biopepela, ali u različitim uvjetima izloženosti. Jedna grupa uzoraka bila je izložena djelovanju klorida, dok je druga grupa bila izložena uvjetima iz vlažne komore.

Abstract (english)

The master thesis describes the process of cement mortar samples preparation using ash from biomass. Main aim is to determine the corrosion behaviour of steel reinforcement when exposed to different cement – biomass content and aggressive environments. The method of determining the effect on corrosion susceptibility of reinforcing steel by potentiostatic electro-chemical test according to HRN EN 480-14 is described and the effects of biomass on the sensitivity of steel reinforcement to corrosion are presented. Also, a comparison of test specimens, of the same composition and content of biomass, but under differently exposed conditions, was made. One group of samples was exposed to 3,5% chloride solution, while the other group was exposed to extremely humid environment.
