Behaviour of Concrete Under High Velocity Impact

Abstract

Steel Fibre reinforced concrete (SFRC) has shown improved engineering properties such as Flexural strength and shattering resistance etc. in comparison to Plain or Reinforced Cement Concrete. This technique has been recommended for the construction of explosive/ammunition storage buildings and processing areas. Experimentation have been undertaken to investigate its behavior against high velocity impact of projectiles. Specially designed model projectiles , of caliber 30 mm were made to interact with different types of concrete such as PCC, SFRC and SFRC reinforced with steel rods, with varying velocities ranging from 50 to 450 m/s. Transient behavior of the interaction has been recorded with high speed photography. In the process of high velocity impact concretes are damaged differently, showing cracking, spalling or scabbing or their combinations. Behavior of various types of concretes against high velocity impact and their comparative performance have been discussed in this paper.
