cube crushing test compression rate

  • Compression Tests on Hardened Concrete Protocol JoVE

    In Europe, cubes (6" by 6" or smaller) are used. Although the ratio of cube strength to cylinder strength decreases as the concrete strength increases, it is often assumed that the strength of a cube specimen will be about 1.25 greater than that of a cylinder. In cylinder tests, the length over diameter ratio (1/d) also influences
