| الوصف: | Da bi se ispitala razlika u kemijskom sastavu i mogućnost primjene jalovine iz rudnika u proizvodnji žbuke i betona uzeti su uzorci s deponija i direktno iz proizvodnje. Nijedan uzorak nije pokazao pucolansku aktivnost. Iz tog razloga, ovaj materijal je moguće koristiti samo kao dkelimičnu zamenu za agregat. U ovom radu je prikazana mogućnost uporabe jalovina u samougrađujućem betonu pripremljenim s portland cementom i sulfatno otpornim cementom. Ispitivani su betonski uzorci u kojima je frakcija agregata 0/4 mm zamijenjena s 10 i 20 % jalovine. Kao pokazatelj trajnosti betona uzete su otpornosti prema zamrzavanju i odmrzavanju sa i bez soli za odmrzavanje. 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. |
