The objective of compressive-strength testing of concrete cylinders is to determine the amount of force it takes to break a cylinder of concrete. A test cylinder is placed in a compression-testing machine, and a constant load is applied to the cylinder until it breaks. The compressive strength is calculated based on the applied load and the ...
