ASTM C39 Procedure. 1. Bring the cylinders out of the moisture room, keeping them covered with wet burlap to keep them moist. Check the cylinders over for defects (holes, cracks, crumbliness) as you set them on the table, use your straight edge and nail to check for planeness, and set the ones with ends that are not plane aside to be saw cut. Similarly, when using the maturity method on your jobsite to test compressive strength, it is recommended to perform cylinder break tests on day-28 of your concrete’s lifecycle for acceptance .Scope: The compressive strength of cylindrical concrete specimens is determined using the ASTM C39 test method.

Core testing is the most direct method to determine the compressive strength of concrete in a structure. Generally, cores may be obtained to assess whether concrete in a new structure complies with strength-based acceptance criteria or to evaluate structural capacity of an existing structure based on in-place concrete strength.
The compressive strength of M20 grade concrete varies between 17 and 23 N/mm2 (i.e. between 170 kg/cm^2 and 230 kg/cm^2) after 28 days curing. This means that the concrete can withstand a compressive load of 170 to 230 kg/cm² before it fails..
