Abstract

Rad obuhvaća izradu uzoraka cementnog morta s različitim vrstama pepela drvne biomase s ciljem određivanja njihovog utjecaja na korozijsku otpornost čelične armature. Izrada uzoraka i određivanje utjecaja osjetljivosti čelične armature provedeni su prema normi HRN EN 480- 14. Ispitivanje je obavljeno potenciostatskim elektrokemijskim ispitivanjem te je prikazan utjecaj pepela drvne biomase na osjetljivost čelične armature na koroziju. Za procjenu ovog utjecaja, dio uzoraka bio je izložen uvjetima iz vlažne komore, dok se drugi dio uzoraka nalazio u NaCl otopini. Uzorci su u prethodno navedenim uvjetima bili izloženi 28 dana. Nakon provedenog ispitivanja napravljena je analiza dobivenih rezultata.

Abstract (english)

The work includes the preparation of cement mortar specimens with different types of wood biomass ash with the aim of determining their influence on the corrosion resistance of steel reinforcement. The preparation of the specimens and the determination of their t influence on the sensitivity of steel reinforcement were carried out in accordance with the HRN EN 480-14 standard. The test was carried out using a potentiostatic electrochemical test and the influence of wood biomass ash on the corrosion sensitivity of steel reinforcement was shown. To evaluate this effect, part of the specimens were stored in a humid chamber while the other part of the specimens were in NaCl solution. The specimens were exposed to the above conditions for 28 days. After the test, an analysis of the obtained results was carried out.
