CIP 35 - Testing Compressive Strength of Concrete WHAT is the Compressive Strength of Concrete? WHY is Compressive Strength Determined?Concrete mixtures can be designed to provide a wide rangeof mechanical and durability properties to meet the designrequirements of a structure. Most deviations from standard procedures for making,curing and testing concrete test specimens will result in alower measured strength. â¢ The range between companion cylinders from the sameset and tested at the same age should be, on average,about 2 to 3% of the average strength.
