This article investigates the punching shear behavior of recycled aggregate concrete (RAC) two-way slabs. Ten 1500 mm × 100 slabs were tested monotonically. Eight cast with RAC, whereas two control natural (NAC). The RAC incorporated coarse (RCA) at replacement levels 25%, 50%, 75% and 100%. Two flexural reinforcement ratios (0.8% 1.5%) examined. results show that normalized strength 100% decre...

Abstract One of the ways for construction sector to contribute sustainability is reuse and recycle huge amount demolition waste (CDW) it generates. Recycled concrete aggregate (RCA) recognized by EN 206 standard as a legitimate ingredient, but their full potential far be used, because several reasons: availability natural resources, heterogeneity CDW, technology costs issues mistrust in perform...
