This study investigated high-strength pervious concrete (HSPC) containing recycled concrete aggregate (RCA) of two sizes including large (9.5–12.5 mm) and small (4.75–9.5 mm). Ultra-high-performance mortar (UHPM) was employed to enhance the inter

Abstract Graphene oxide (GO) has achieved significant progress in the material behaviour of cement-based materials. However, research on its structural behaviour in high-strength lightweight concrete (HSLWC) structures is limited, which restricts its

Abstract To achieve dual optimization of the mechanical properties and environmental impacts of geopolymer concrete (GPC), this study proposes a high-strength geopolymer concrete (HSGPC) without coarse aggregate. The mix proportion of HSGPC was optim
