Abstract: The ballistic performance of plain concrete and reinforced concrete targets of unconfined compressive strength 40 MPa was studied against projectile impact. The squarer plates of (450 mm x 450 mm) and thickness 60 mm with and without (8 mm@100 mmc/c) reinforcement were subjected to normal impact of hardened steel ogive nosed projectiles with diameter 19 mm and mass 0.5 kg. The incident velocities of the projectiles were varied between 28 to 102 m/s. The amount and area of damage, volume of spalling and scabbing as well as the ballistic limit of plain and reinforced concrete have been obtained and their results have been compared and discussed. The influence of reinforcement is clearly visible in minimizing the scabbing and spalling of material. The magnitude of scabbing decreased with increase in the projectile incidence velocity while the spalling of material remained unaffected. The ballistic limit of reinforced concrete target was 20% higher than plain concrete target for 60 mm thickness. ¬© 2017 The Authors.
