CIP 35 - Testing Compressive Strength of Concrete

Compressive Strength of Cylindrical Concrete Specimens. A test result is the average of at least two standard-cured strength specimens made from the same concrete sample and tested at the same age. In most cases strength requirements for concrete are at an age of 28 days. Design engineers us the specified strength ƒ´ c to design structural elements.
