Mechanical properties of roller compacted concrete containing recycled concrete aggregate

Abstract The compressive strength, splitting tensile strength, pulse velocity and drop weight impact resistance of roller compacted concrete (RCC) mixtures containing recycled concrete aggregate (RCA) were investigated. The cement contents of the RCC mixtures were chosen as 150, 200 and 250 kg/m3. I...

The cement contents of the RCC mixtures were chosen as 150, 200 and 250 kg/m3. In addition to the control mixtures containing no RCA, 25, 50, 75 and 100 wt% of the crushed limestone aggregate was replaced with RCA. In this way, 15 RCC mixtures were prepared.

The results showed that increasing the amount of recycled aggregate decreased the mechanical properties of the concrete.
