device for determination of compressive strength of concrete

Testing the Compressive Strength of Concrete — What,

The compressive strength of concrete is the most common performance measure used by the engineer in designing buildings and other structures. 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
