TESTS FOR DETERMINATION OF COMPRESSIVE STRENGTH OF CONCRETE

11-06-2021  One of the important properties of concrete is its strength in compression. The strength in compression has a definite relationship with all other properties of concrete i.e. these properties improved with the improvement in compressive strength. Thus, with this single test one judge that whether Concreting has been done properly or not.
