The cylinder specimen of concrete (150 diameter and 300 height) is a standard specimen to test the compressive strength in United States. While in Britain and Europe, the standard specimen for testing the compressive strength is a cube specimen of concrete by size 150 × 150 × 150 mm (Kim and Seong-Tae, 2002).
Compressive Strength The main measure of the structural quality of concrete is its compressive strength. This property of concrete is commonly considered in structural design. Depending on the mix (especially the water-cement ratio) and time and quality of the curing, compressive strength of concrete can be obtained up to 14,000 psi or more. Commercial production of concrete with ordinary ...

The Compressive strength test will result in a compressive load on the cube and the cylinder during the test procedure. This process will result in the Lateral Expansion of the sample which will result in the Poisson's ratio effect. The figure-1 below shows the compressive testing arrangement of a cube.

American Society for Testing Materials ASTM C39/C39M provides Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens.
May 18, 2018· Concrete being the major consumable material after water makes it quite inquisitive in its nature. The strength of concrete is majorly derived from aggregates, where-as cement and sand contribute binding and workability along with flowability to concrete.. This is an in-depth article on Compressive Strength of Concrete.
Compressive strength as per American Codes. In case of American codes, compression strength is defined in terms of cylinder strength fc'. Here compressive strength of concrete at 28 days curing is obtained from a standard cylindrical specimen 150mm diameter and 300mm high loaded longitudinally to failure under uniaxial compression loading.
ASTM C39 | Concrete Cylinders | Compression Testing. ASTM C39 determines the compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It is limited to concrete having a unit weight in excess of 50 lb/ft3 (800 kg/m3). A compressive axial load is applied to molded cylinders or cores until failure occurs.

Compressive strength of concrete cube test provides an idea about all the characteristics of concrete.By this single test one judge that whether Concreting has been done properly or not. Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structures.
May 30, 2016· In China, the compressive strength tested by the cube(150mm or 100mm), and the ratio between the strength test on cubic sample is 1.0/0.95。 According to some experiments, the strength of cube is about less 10MPa than that of cylindrical sample. S...
EFFECT OF SPECIMEN SIZE AND SHAPE ON COMPRESSIVE STRENGTH OF SELF-COMPACTING CONCRETE Diyala Journal of Engineering Sciences, Vol. 07, No. 02, June 2014 17 expected that the strengths of cubes and cylinders made from the same concrete differ from one another (2).
The compressive strength of concrete is the most common performance attribute which is used by the engineer when designing the structures. The compressive strength of concrete ensures that the delivered concrete mix will meet the requirements of the specific strength as designed by the engineer according to the work specifications and requirements.
