The compressive strength of hardened concrete is one of the most important and useful properties of concrete. In most of the structural uses, the concrete is used mainly to resist the compressive stresses. In situations where the shear or tension strength is of importance, the compressive strength is usually used as a measure of these properties.

Test for Compressive Strength. The most common test preformed on concrete is for compressive strength. There several reasons for this: (1) it is assumed that the most important properties of concrete as directly related to compressive strength; (2) concrete has little tensile strength and is used primarily in compression; (3) structural design ...

Compression Tests on Hardened Concrete Protocol

For the compression test, the load capacity has to be very high (300,000 lbs or 300 kips or more) in order to test high strength concretes, as the 12 in. cylinders have an area of 28.2 in. 2, and concrete strengths can range up to 20 ksi in practical applications. This type of concrete will require a machine with a capacity of at least 600 kips.
