Abstract
The study tests recycled mixed aggregates (RMA) from C&D waste as substitutes for natural aggregate in non-structural vibro-pressed precast elements—terrazzo (indoor), hollow tiles, kerbstones, and paving blocks—at 25/50/75/100% replacement. Mix cement/water dosages were kept as in industry, and pieces were produced in real plants and monitored up to 360 days for strength, absorption, abrasion, slip resistance, dimensional tolerances, etc. Kerbstones, paving blocks and hollow tiles met the relevant standards across the tested ranges; terrazzo with RMA showed poorer surface finish than with natural aggregate. Results support industrial feasibility of RMA for non-structural precast products, advancing circular use of C&D waste.
