| Abstract: |
Sustainable concrete with precipitated calcium carbonate (PCC) and upcycled concrete aggregate (UCA) offers a promising solution for reducing the environmental impact of concrete. While recent studies have primarily focused on the axial compressive strength of green concrete with PCC and UCA, the axial behavior of such concrete confined with steel spirals remains unexplored. Therefore, this study investigates the stress-strain behavior of green concrete made with 100% UCA and 15% PCC as cement replacement, confined using steel spirals with reinforcement ratios of 1.16, 1.94, and 3.11. The results demonstrate notable improvement in the stress-strain response of confined concrete. Up to 56.22% and 58.12% increase in the peak strength and corresponding strain was observed. |
