ASTM C109 is used to determine the compressive strength of concrete by testing a 2 inch hydraulic cement mortar cube to failure. This standard also outlines the various equipment and procedures required to create, mold and prepare the specimens prior to testing. It is very important that the steps and verification are followed to ensure satisfactory test results. ASTM C109 is primarily used by departments of transportation, academic institutions, and manufacturers of consumer and industrial products.
