  • Compressive Or Crushing Strength - ChestofBooks.com

    The compressive strength of concrete is very important, as it is used more often in compression than in any other way. It is rather difficult to give average values of the compressive strength of concrete, as it is dependent on so many factors.The available aggregates are so varied, and the methods of mixing and manipulation so different, that tests must be studied before any conclusions can ...

    Compressive (Crushing) Strength. Amount of compressive stress at the onset of failure. The definition of failure tends to vary with material type. As with tensile tests, the terms ultimate and yield can be used. However, ductile materials do not break during compressive testing, and therefore have no ultimate compressive strength.
