This study assesses the technical and economic feasibility of using construction and demolition waste (C&D waste) as a partial replacement for coarse aggregate in low-strength concrete (140 kg/cm²), specifically for applications in spread footings. Four mix designs were developed: one standard mix without C&D waste and three with 15%, 30%, and 45% C&D waste, respectively. The mixes were evaluated through slump tests and compressive strength tests at different ages (3, 7 and 21 days), as well as complementary tests for air content and temperature. The strength results showed that all mixes with C&D waste consistently exceeded the design strength, maintaining workability and confirming the technical feasibility of using C&D waste as a replacement. The economic analysis revealed a cost reduction with higher C&D waste percentages, with savings of up to 5% per cubic meter of concrete. These findings suggest that incorporating C&D waste into concrete is a sustainable and cost-effective alternative that contributes to the proper management of construction waste in Lima, Peru.
