Abstract: Concept of sustainable development, which beside sociological and economic aspects, includes saving of energy, environment protection and preservation of restorable natural resources, presents strategic determination of various economic sectors. During the ore flotation in the mine large amounts of flotation tailings are generated and as waste material disposed in the specially determined areas. With the increase in metal production, the amount of tailings also increases, which is a major environmental problem because it takes up large areas. Great production of fly ash, which is the main residue from combustion of coal,also "managed" by landfilling, is a huge risk and danger for environment.Unlike vibrated concrete, self-compacting concrete contains significant amounts of fine particles, i.e. a mineral additive that greatly affects its performance, where potential use of fly ash is very important ecological aim. Tailing test results showed no pozzolanic activity and so its application in concrete can be only a partial replacement of aggregate.This paper presents the possibility of using tailings and fly ash, which are waste products, in Self – Compacting Concrete. The obtained results indicate that these materials can successfully be used.
