  This paper presents a study on the compressive strength behavour of copper slag admixed fibre reinforced concrete. Attempts have been made to find relationship between Compressive Strength, Ultrasonic Pulse Velocity and Rebound Hammer values considering the effect of fibre content (0%, 0.5%, 1%, and 1.5%). In the present experimental investigation, concretes of grade M20 & M30 were used with crimped steel fibres having an Aspect Ratio of 60.
