Sažetak
Concrete resistance to chloride ions is of crucial importance for reinforced concrete structures exposed to aggressive marine environment. This study shows one of the possibilities to increase concrete resistance to chloride penetration by use of ternary blended cement. Combination of three mineral additions in cement such as slag, fly ash and limestone, which were investigated in this study, is insuring less penetration of chloride ions into concrete. It was shown that diffusion of chloride ions into the concrete prepared with different types of ternary blended cements significantly decreased in comparison to the referent concrete. Concrete prepared by cement with 50% of mineral additions has shown to be more compact and less porous concrete and with almost the same other mechanical properties such as compressive and flexural strengths, comparing to the referent concrete.
