Abstract - Concrete is the main material used in construction, composed of water, fine aggregate, coarse aggregate, and cement. The aggregates, sourced from nature, are depleting rapidly due to excessive use for development, creating a future shortage. To address this, it's essential to find alternatives. Demolition waste, a byproduct of construction and renovation Demolish concrete is huge problem we are facing now a days waste accumulates in large quantities, hampers the environment of disposal sites. The aggregate resource is limited it create imbalance between the high demand and supply. We collected demolished concrete from the construction site at Yashoda Technical Campus, Satara and we did several procedures on it such as separation, crushing, sieving, washing and quality control. We have Replaced natural aggregate with RCA of 10% to 40% were taken into account. Both the 7 and the 28 days strength were used for the examinations. We got maximum compressive strength for M25 grade of concrete at 10 % replacement but we can also use 40% RCA
Key Words: Recycled Coarse Aggregate, Compressive Strength, Crushing Strength, M25 grade concrete
