Abstract
The waste generated by construction industries in many countries around the world is increasing significantly with the continued expansion of urbanization and industrialization, leading to numerous environmental and financial problems. Waste from brick production can be used as a stabilizing material for silty soil, which has caused damage to various roads and buildings. Utilizing waste bricks helps reduce environmental impact, minimize material waste, and conserve valuable resources. This study investigates the effect of waste brick grains on the stabilization of OUED RASS sand, which has low shear strength, thereby mitigating the environmental impact of waste bricks. The research involves processing a sand-silt mixture reinforced with 10% and 20% waste bricks of 1mm diameter. This mixture enhances shear strength up to 170 kPa in sand reinforced with 20% brick waste under a normal stress of 100 kPa, at a relative density of 90%, with fines contents of 10% and 20%, in a dry state with a water content of 0%. This reinforcement using brick waste increases soil cohesion but reduces the friction angle.
