Abstract

Construction waste is a significant contributor to global solid waste, underscoring the need for effective sustainable management strategies. This study aims to assess the quality and environmental impact of paving blocks manufactured from two different sizes of recycled aggregates. Two categories, CA1 (12.5–4.75 mm) and CA2 (37.5–4.75 mm), were used as constituent materials. The paving blocks were assessed based on compressive strength, water absorption, and wear resistance. Experimental results indicate that paving blocks incorporating CA2 recycled aggregates performed better than those with CA1. The tested paving blocks meet grade D standards for garden paving (CA1) and grade C standards for pedestrian pathways (CA2). Additionally, utilizing recycled aggregates from concrete waste enables 48.1% rubble recycling and reduces carbon dioxide emissions by 64.7%, thereby contributing to sustainable waste management.
