This paper analyses the generation and re-use of different types of industrial wastes. From examined wastes, blast-furnace slag and washed recycled concrete were prepared our tested concrete samples with dimension 150×150×150 mm. In these samples were fraction 0- 4 mm replacement by blast-furnace slag with a range of variation from 0 to 100%. Fraction 4–8 mm and 8-16 mm were replacement by aggregate prepared from washed recycled concrete parts with a range of variation from 0 to 100% in both fractions. Concrete samples contained aggregate prepared form recycled concrete and blast-furnace slag, are tested after 14 and 28 days of hardening. From the obtained results follows that washed recycled concrete and blast-furnace slag can be successfully used as a natural aggregate replacement in concrete production and has not negative effects on the properties of hardened concrete. Before mass using of these selected wastes, some important properties (durability and corrosion) of recycled concrete and blast-furnace slag concrete are necessary to investigate.

Keywords: blast-furnace slag, aggregate from recycled concrete, compressive strengths, concrete.
