ASTM C39/C39M-20,Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens.
A few days ago, I received an email from a netizen named Jack who said that he could not find ASTM C39 on my website. I took the time to search on my website, but I didn’t find it, so I finally got this standard document from a friend of mine. I hope it helped.
The keywords of this standard:concrete core; concrete cylinder; concrete specimen; concrete strength; compressive strength; core; cylinder; drilled core; strength
ASTM C39/C39M-20 covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It consists of applying a compressive axial load to molded cylinders or cores at a rate which is within a prescribed range until failure occurs.
