Understanding Minimum Specified Compressive Strength

Understanding Minimum Specified Compressive Strength ( f ’ c) Jereme Montgomery I have always said concrete strength is overrated. Compressive strength is only one characteristic of concrete that does not seem well understood by all. Project specifications are always specified with some minimum compressive strength requirement with the notation, f ’ c. If you have read my “Durability,Concrete Compressive Strength - an overview,,Conventionally, structural concrete strength is specified as the compressive strength of standard 300 mm by 150 mm cylinders according to the American Concrete Institute code or 150 mm cubes based on the British Standard, tested at 28 days, and such specimens are routinely cast and tested to monitor the quality of the concrete coating. However, due to the method of application and the dryness,Compressive Strength of Concrete | Definition,,29/01/2017· Data Acquirement from Compression Strength: Design engineers use the specified strength to design structural elements.
