Measuring Compressive Strength Precast concrete
A concrete compressive strength test machine works by progressively applying force on a specimen. Because strength is defined as the maximum load carried divided by the average crosssection area, the most logical way to determine the strength of a specimen is to load it until it fails.

Verifying Compressive Strength of Masonry
One is the unit strength method and the other is testing masonry prisms for compressive strength. The unit strength method verifies the compressive strength of the individual materials and then uses tables to determine compressive strength of the assembly from that information.

How to Calculate a Concrete Pad Load | Sciencing
Not all concrete is the same strength. Before trying to determine how strong a pad is, you must first know how strong the concrete is. This is normally measured as compression strength, measured by pounds per square inch, or psi.
