Abstract
The paper attempts to assess the influence of raw concrete material quality on selected properties of RCAs. Volumetric density, bulk density, voids, crushing strength, water absorption, mineral dust content for RCA, obtained from crushed primary concrete having different compressive strength, were examined. RCA was obtained by crushing laboratory concrete having a wide range of water/cement (w/c) ratio (from 0.35 to 0.7); it allowed to obtain the concrete having compressive strength from 30 to 60Â MPa. The research also included recycled concrete with the secondary aggregate having optimal granulation (selected empirically and with the assumption of the lowest voids of the aggregate composition).
