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 The utilization of processed rubber and construction waste in lieu soil as a substrate could improve significantly seismic performance, while addressing the pressing environmental issue how to reutilize dispose of, i.e., automotive tires demolition by-products. In this study, series laboratory tests explore influence recycled tire (RTW) concrete aggregate (RCA) fine particles on compre...
