Abstract
The world is experiencing rapid infrastructural development. This requires a higher quantity of aggregate resulting in a higher amount of natural resources depletion. Also, waste generated from demolition or collapse of the building ends in landfills unlawfully. The strains and high values on existing lands caused by rapid urbanization are making securing dump sites increasingly difficult. These situations have resulted in an environmental threat that needs urgent attention. This research investigated the potential usage of demolished concrete aggregate (DCA) as a partial replacement of granite to produce structural concrete. Laboratory testing of granite, DCA, and the produced concrete was carried out according to British and ASTM standards. The physical properties of DCA present the material to be a potential construction material for sustainable construction and a greener environment. The strength result of DCA concrete keeps reducing as the percentage replacement increases but yet produced satisfactory structural concrete.
