ASTM C39 has remained the industry standard for testing the compressive strength of cylindrical concrete specimens for more than 80 years. ASTM C39 covers the determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores.
The results of this test method are used as a basis for quality control of concrete proportioning and mixing, and are used by departments of transportation to ensure that concrete structures such as roadways and bridges are safe for travel and will adhere to their predicted lifespan.
