Thus 'Fifty Newton concrete,' means concrete which has achieved 50 Newtons per square millimetre, or 50 Mega Pascals. While measurements based on concrete cubes are widely used in the construction industry, the European standard for cement manufacture, EN 197, specifies a test procedure based on mortar prisms, not concrete cubes.
