    Compressive strength in concrete test

     · TEST PROCEDURE Scope: • The test method covers determination of compressive strength of cubic concrete specimens. • It consists of applying a compressive axial load to molded cubes at a rate which is within a prescribed range until failure occurs. • The compressive strength is calculated by dividing the maximum load attained during the test by the cross sectional area of the specimen.
