    Testing The Compressive Strength Of Concrete What Why

    The compressive strength is measured by breaking cylindrical concrete specimens in a compressiontesting machine. The compressive strength is calculated from the failure load divided by the cross-sectional area resisting the load and reported in units of pound-force per square inch psi in US Customary units or megapascals MPa in SI units.

    Standard Test Method For Compressive Strength Of Concrete

    4.1 Cast-in-place cylinder strength relates to the strength of concrete in the structure due to the similarity of curing conditions because the cylinder is cured within the slab. However due to differences in moisture condition degree of consolidation specimen size and length-diameter ratio there is not a unique relationship between the strength of cast-in-place cylinders and cores of the same age.
