Compressive Strength of ConcreteConcrete Cubes What

Compressive strength as per American Codes. In case of American codes, compression strength is defined in terms of cylinder strength fc’. Here compressive strength of concrete at 28 days curing is obtained from a standard cylindrical specimen 150mm diameter and 300mm high loaded longitudinally to failure under uniaxial compression loading.

Tensile testing Wikipedia

Tensile testing, also known as tension testing, is a fundamental materials science and engineering test in which a sample is subjected to a controlled tension until failure. Properties that are directly measured via a tensile test are ultimate tensile strength, breaking strength, maximum elongation and reduction in area. From these measurements the following properties can also be determined
