Abstract
Alkalno – aktivirani materijali predstavljaju novu generaciju bezcementnih veziva koji se baziraju na reakciji izvora alkalnog metala (aktivatora) s čvrstom praškastom sirovinom (prekursor). Čvrste faze mogu biti bazirane na kalcijevom silikatu ili aluminosilikatu kao što su metalurška zgura, prirodni pucolani, leteći pepeo. Aktivatori su topive tvari koje opskrbljuju katione alkalijskih metala, podižu pH otopine i ubrzavaju otapanje krutog prekursora. U radu je obrađeno stanje znanja područja utjecaja različitih prekursora i aktivatora na svojstva alkalno – aktiviranih materijala koja definiraju korozijsko ponašanje čelika u betonu. U eksperimentalnom dijelu rada pripremljene su različite vrste alkalno – aktiviranih veziva te su provedena ispitivanja tlačne čvrstoće, pH vrijednosti, migracije klorida, električne otpornosti i korozijskog ponašanja čelika u mortu.
Abstract (english)
Alkali – activated materials present a new generation of cementless binders which are based on the reaction of an alkali metal source (activator) with a solid powder material (precursor). The solid material may be based on calcium silicate or aluminosilicate such as metallurgical slag, natural pozzolan and fly ash. Activators are soluble substances that supply alkali metal cations, raise the pH of the solution and accelerate the dissolution of the solid precursor. The paper deals with the state of knowledge in the field of influence of different precursors and activators on the properties of alkali-activated materials that define the corrosion behavior of steel in concrete. In the experimental part, different types of alkali-activated binders were prepared and the following properties were tested: compressive strength, pH value, chloride migration, electrical resistance and corrosion behavior of steel in mortar.
