The suitability of crushed pebbles waste as a fine aggregate for concrete has been assessed by comparing its basic properties with that of conventional concrete. Basic mix was chosen for natural sand to achieve M25 grade concrete. The equivalent mixes were obtained by replacing natural sand by crushed pebbles partially and fully.
