Optimising the mechanical properties of concrete for non-structural applications through partial replacement of fine aggregates with wastewater sludge

Abstract This study investigated the potential of wastewater sludge (WWS) as a partial replacement for fine aggregates in non-structural concrete to optimise its mechanical properties while mitigating environmental impacts. WWS from three wastewater treatment plants (WWTPs), Mankweng, Polokwane, and...
