  • Compressive Strength of Concrete and Concrete Testing

    Concrete cube testing or cylinder testing is done to check the development of the strength of the concrete. In other words, we test the concrete to check whether it has reached or developed beyond the characteristic strength of concrete assume in the design. Based on the test results, conformity can be checked as per the relevant standards.

    The range of strength for sandcrete blocks specified by N.I.S 74:1976 is between1.8N/mm2 to 2.5N/mm2 as the minimum strength. The blocks can cope with thermal and moisture conditions, and the problem of algae growth on the face of block work during construction is unlikely to affect the strength of the block (Edward, 1985).
