ABSTRACT
This paper reports on the experimental punching shear behaviour of simply supported structural slabs realized by reinforced Recycled aggregates Concrete (RC) made with coarse recycled aggregates by demolished concrete only (CRcA). This investigation was made with the aim to provide a best understanding of RC slabs structural behavior. The experimental campaign has been carried out on 12 reinforced RC slabs. Three reinforced Natural aggregate Concrete (NC) slabs have been casted and tested as control specimens. Four CRcA replacement percentages (30, 50, 80 and 100%) have been considered. The tests on the punching shear behavior of simply supported reinforced RC slabs have been analyzed. The results show that the punching shear strength of RC and NC slabs are very similar.
