Abstract
The work investigates replacing natural aggregate with recycled aggregates from construction & demolition waste (C&DW) to manufacture precast, non-structural concretes (paving blocks and hollow tiles). A laboratory program assessed mechanical performance and service properties; mixes with selected C&DW fractions achieved requirements suitable for these precast products, supporting material circularity and reduced consumption of virgin aggregates.
