Abstract

S ciljem očuvanja okoliša, u tehnologiji betona, nastoje se pronaći nova veziva koja bi se koristiti kao zamjena za cement, s obzirom da se prilikom proizvodnje klasičnog cementa troše velike količine energije i prirodni resursi te se emitiraju značajne količine u atmosferu. Jedno rješenje ovog problema predstavljaju upravo alkalno aktivirana veziva tako tema ovog rada alkalna aktivacija metakaolina s udjelom crvenog mulja. Naime, proizvodnju metakaolina se troši manje energije nego za proizvodnju cementa, dok je crveni mulj industrijski otpad proizvodnje aluminija, što ih čini ekološki prihvatljivijim rješenjem cementa.

Abstract (english)

In regards to the agenda of preserving the environment, concrete technology seeks to find new binders that could be used as a replacement for cement, given that the production classic Portland cement consumes large amounts of energy and natural resources and emits significant amounts of CO2 into the atmosphere. One solution to this problem is alkaline- activated binders, so the topic of this paper is the alkaline activation of metakaolin proportions of red mud. Namely, less energy is used for the production of metakaolin than the production of cement, while red mud is an industrial waste of aluminium production, which makes them a more environmentally friendly solution than cement.
