  • Standard Test Method for Compressive Strength of ...

    5.1 Care must be exercised in the interpretation of the significance of compressive strength determinations by this test method since strength is not a fundamental or intrinsic property of concrete made from given materials. Values obtained will depend on the size and shape of the specimen, batching, mixing procedures, the methods of sampling, molding, and fabrication and the age, temperature ...

  • Relation Between Compressive and Tensile Strength of Concrete

    The tensile strength of concrete is more sensitive to inadequate curing than the compressive strength, possibly because the effect of non-uniform shrinkage of flexure test beams are very serious. Thus air-cured concrete has a lower ft/fc´ ratio than concrete cured in water and tested wet.

  • Standards for 7-day and 28-day strength test results

    Standards for 7-day and 28-day strength test results. No strength test falls below the specified compressive strength by more than 500 psi (3.5 MPa) if the specified compressive strength is 5000 psi (35 MPa) or less; or by more than 10 percent of the specified compressive strength if the specified compressive strength exceeds 5000 psi (35 MPa).

  • Civil Engineering: Compressive strength of concrete cube TEST

    Test for compressive strength is carried out either on cube or cylinder. Various standard codes recommend concrete cylinder or concrete cube as the standard specimen for the test. American Society for Testing Materials ASTM C39/C39M provides Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens.

  • Testing the Compressive Strength of Concrete — What, why ...

    HOW to Test the Strength of Concrete Cylindrical specimens for acceptance testing should be 6 x 12 inch (150 x 300 mm)... Recording the mass of the specimen before capping provides useful information in case of disputes. To provide for a uniform load distribution when testing, cylinders are capped ...
