Investigate the usage of sawdust and peanut shells in producing stabilized earthen bricks for desert buildings: A case study, Adrar, South Algeria

Résumé

Abstract: This study aims to enhance the stabilization of earthen bricks for improved environmental sustainability, cost-effectiveness, and resilience in hot desert climates, while meeting architectural construction demands. Traditional earthen bricks, recycled from local earthen bricks used in Ksours, were stabilized with 10% cement and reinforced with peanut shell fines and sawdust (in fine and fiber forms). These reinforcements utilize waste materials to enhance the mechanical and thermal properties of the bricks. Various compositions (0%, 5%, and 10% additives) were tested for compressive strength, flexural strength, and thermal conductivity after 28 days. Results showed reduced density, improved strength, enhanced thermal performance, and mechanical properties, confirming the materials' effectiveness.
