More### ultimate compressive strength Mecmesin

Ultimate Compressive Strength is defined as the force at which a specimen with a certain cross-section, and consisting of a particular fracturing material, fails when it is subjected to compression. The ultimate compressive strength is normally measured in N/mm2 (force per area) and is thus a stress.

More### 95. Compressive Strength of Concrete

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
