Historical strength test records are used by the concrete producer to establish the target average strength of concrete mixtures for future work. HOW to Test the Strength of Concrete Cylindrical specimens for acceptance testing should be 6 x 12 inch (150 x 300 mm) size or 4 x 8 inch (100 x 200 mm) when specified.
