Sažetak

In order to examine the differences in chemical composition and the possibility of using mine tailings in mortar and concrete production, samples were taken from the landfill and directly from the production. Tailings test results showed no pozzolanic activity and that its application in concrete can be only a partial replacement of aggregate. This paper presents the possibility of using tailings in self-compacting concrete made with Portland cement and sulphate resistant cement. Concrete specimens in which the aggregate fraction 0/4 mm was replaced with 10 and 20 % of tailings were examined. The resistance to freezing and thawing with and without de-icing salts is used as an indicator of concrete durability.
