Abstract - In recent years, handling and management of demolished concrete waste have emerged as a prominent challenge faced by countries worldwide. Addressing this issue presents a significant challenge that necessitates indigenous solutions. Repurposing demolished concrete waste is increasingly recognized as essential for preserving natural resources and reducing environmental pollution. A research project has been initiated to investigate the viability and recycling prospects of repurposing demolished concrete waste for future construction endeavors. Focus of the current investigation is Exploring the reuse of demolished waste materials to diminish construction impact costs and address housing shortages encountered by underprivileged communities worldwide. The crushed demolished concrete waste undergoes segregation via sieving to obtain the Specified dimensions of aggregate. Subsequently, various test are conducted to know the aggregate properties prior to its upcycling into new concrete. Following procedures were carried out: 1. Concrete mix design was executed, replacing 75% of sand with reclaimed concrete aggregate. 2. Concrete mix design was executed, replacing 100% of sand with reclaimed concrete aggregate. 3. Aggregate crushing, impact, and abrasion tests were performed. 4. Nine cube were cast and tested for 3,7&28 day. This thesis demonstrates the capability of reclaimed aggregates obtained on-site in producing high-quality concrete
