CIP 35 Testing Compressive Strength of ConcreteStandard Test Method for Compressive Strength of

The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structur The compressive strength is measured by breaking cylin drical concrete specimens in a compression testing machine The compressive strength is calculated from the failure load51 Care must be exercised in the interpretation of the significance of compressive strength determinations by this test method since strength is not a fundamental or intrinsic property of concrete made from given materials Values obtained will depend on the size and shape of the specimen batching mixing procedures the methods of sampling molding and fabrication and the age
