Abstract. Bricks are fundamental construction units, valued for their durability, thermal properties, and versatility in load-bearing and non-load-bearing structures. With the growing concerns over the environmental footprint of conventional building materials, a promising approach is the utilisation of agricultural and industrial by-products in lieu of conventional materials to reduce environmental impact while meeting structural and durability needs. This study investigates the impacts of incorporating sawdust (SWD) and eggshell powder (ESP) in the production of cement-stabilised laterite bricks. The index properties of laterite sample were determined, different composite mixes of SWD, ESP, cement and laterite in different proportions were evaluated for the compressive strength at 7, 14 and 28 days, water absorption, and thermal conductivity tests were also conducted. The results show that an increase in SWD contents resulted in lower structural strength and higher water absorption, and the inclusion of ESP enhances both the strength and thermal insulation. ESP also enhances the durability of bricks by reducing the water absorption ability. By examining these alternative raw materials for brick production, the research contributes to the development of eco-friendly construction practices which aligned with global sustainability and resource efficiency goals.
