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.   |
