Due to the high amount of construction and demolition waste (CDW) generated, the recycling and reuse of these materials is an important factor for the sustainability of the whole building sector. The use of CDW as recycled aggregate is a high-quality recovery; however, contaminations that may emerge during the service life of a building, have to be considered. Part 1 of this publication deals with inorganic contaminants. Within a large research project numerous CDW samples from a commercial recycling plant were investigated in granular form. Selected samples were used as aggregates and the leaching of the resulting concretes was tested. In addition a doped concrete was tested to simulate a higher degree of contamination. The results show, that inorganic compounds are well bound in the concrete. The German limit values for the leaching of unbound CDW guaranty a save use, however there is no direct correlation between the leaching of unbound CDW and concrete with CDW aggregate, because the leaching of concrete is dominated by the binder.
