Natural aggregate replacement by recycled materials in concrete production

Junak J., Stevulova N.

In this contribution is presented overview of aggregate from recycled concrete and steel making slag treatment in civil engineering industry. The goal of experiments is utilization of these wastes as the partial or complete replacement of natural aggregates fraction 4-8 and 8-16 mm in concrete. Partial replacement was carried out from 20 to 80 %.
