N2 - More and more countries are looking at ways to recycle waste reclaimed from demolition. In this paper, the properties of the aggregate (virgin and reclaimed from waste), the dried concrete as well as the structural behaviour of beam element have been investigated. Specimens with six different percentages (0, 20, 40, 60, 80 and 100%) of recycled concrete aggregate (RCA) were cast in an industrial plant. Water cement ratio was kept constant and the loss of slump was compensated by the use of super plasticizers. This study shows that the mechanical properties of RCA are acceptable also they are slightly lower than virgin aggregate. Similar results have been obtained for the concrete compressive strength. The beam specimens had similar failure loads also the number of cracks typically increases as well as the deflection of the specimens with increasing percentage of RCA used in the mixture.
