Influence of binder based on wood biomass on corrosion resistance of reinforcing steel

Pepeo koji preostaje nakon izgaranja drvne biomase razmatra se kao moguća zamjena za dio cementa u betonu. Utjecaj takve zamijene na fizikalna, mehanička i trajnosna svojstva betona je djelomično istražen. S obzirom na to da bilo kakva zamjena cementa s alternativnim materijalima utječe i na kemijska svojstva veziva i porne vode, nužno je provesti istraživanja utjecaja zamjene cementa pepelom iz drvne biomase na korozijsku otpornost armaturnog čelika. Cilj rada je ustanoviti korozijske parametre armature u mortovima pripremljenim sa zamjenom dijela cementa s pepelom iz drvne biomase. Potrebno je provesti ispitivanje metodama pripremljenim prema preporukama iz stanja područja.The ash remaining after combustion of biomass is considered as a possible replacement for part of the cement in concrete. The impact of such substitution on the physical, mechanical and durability properties of concrete has been partially researched. Since any substitution of cement with alternative materials also affects the chemical properties of binder and pore solution, it is necessary to conduct research into the impact of wood ash cement replacement on corrosion resistance of reinforced steel. The aim of this study is to establish the parameters of corrosion of reinforcement in mortar prepared with partial substitution of cement with wood biomass. It is necessary to conduct tests according to there commendations available in the literature
