The experiment explores using demolished brick aggregate, specifically Jhama brick, as a substitute for traditional coarse aggregate in concrete production. Different proportions of Jhama brick (15%, 25%, and 35%) were tested in M25 grade concrete. Testing included fresh and hardened concrete characteristics like workability and compressive strength at 7 and 28 days. Results showed that a 25% replacement of Jhama brick was cost-effective and had suitable strength for moderate load structures, although overall strength was lower than standard concrete.
