Cylindrical specimens are tested in accordance with ASTM C 39, Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens. A test result is the average of at least two standardcured. strength specimens made from the same concrete sample and tested at the same age.
Crush Cube Testing The concrete crush and cube test is an effective test to determine the compressive strength of concrete. Samples are taken from the concrete cured under standard conditions and crushed to determine the maximum compressive strength in our UKAS accredited laboratory.
Normally it is minimum requirement at site to provide evidence of cube test result to confirm the required concrete strength. The cubes are normally tested on 7 and 28 days, until any early specific test is required. 6 Cubes are casted at the time of concreting, 3 cubes for 7 .
Testing. Carefully align the specimen with the spherically seated plate. The load will be applied to the specimen axially. Now slowly apply the load at the rate of 140kg/cm2 per minute till the cube collapse. The maximum load at which the specimen breaks is taken as a compressive load.
Cube moulds are used for testing of hardened cement concrete works. The purpose of testing hardened concrete is to confirm that the concrete used at site has developed the required strength. Normally it is minimum requirement at site to provide evidence of cube test result to .

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 ...
