Test the specimens promptly after . 5.2 Method C, uniaxial compressive strength of rock is used in many design formulas and is sometimes used as an index property to select the appropriate excavation technique. Deformation and strength of rock are known to be functions of confining pressure. Method A, triaxial compression test, is commonly used to simulate the stress conditions under which .The ASTM C39 test standard for compressive strength of concrete cylinders requires numerous checks for dimensions of the concrete cylinders and alignment during testing. The manual instructs and illustrates acceptable practices to properly perform these measurements. C39 gives basic requirements for concrete compression testing machines, but the manual provides .cast from a concrete sample taken from the discharge of a truck or a batch of concrete. They are molded and cured following the standard procedures of ASTM C31/C31M and tested as required by ASTM C39/C39M. If the concrete is so prepared, cured, and tested, the results are the compressive strength of the concrete cured under controlled conditions,
