The concrete structural code Eurocode 2 (BS EN 1992) is based on cylinder compressive strength.
A relationship between the strength of 150mm diameter cylinders of 300mm length and 150mm cubes is given and is adopted by EN 206. In the UK, BS 8500 states that the compressive strength of 150mm cubes and 100mm cubes are considered equivalent.
A correction factor is not used in the European standards. 100, 150 or 200mm cubes can be used without correction to the compressive strength obtained from the test when checking for strength class conformity.
