### COMPRESSIVE STRENGTH OF NORMAL STRENGTH

compressive strength is usually measured based on 150 mm cubes according to BS approach. But in future the design compressive strength is usually based on the standard 150 x 300 mm cylinders as recommendation by Eurocode. Compression Test Rebound Hammer Test and Ultrasonic Pulse Velocity Test method are used to determine the compressive strength.
