2015-3-3  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.
