Scope 1.1 This test method covers determination of 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).

Concrete cylinder and cube specimens for compression testing were compared through a survey of past research, including testing procedures, factors affecting the cylinder/cube strength ratio, and conversion factors and equations.

For this reason, standard concrete cube (height/diameter ratio =1) specimen gives higher compressive strength then the cylindrical specimen (height/diameter ratio=2) Cube strength of concrete is nearly 1.25 times the cylindrical strength.

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.

1.1 This test method covers determination of compressive strength of cylindrical concrete specimens such as molded cylinders and drilled cores. It is limited to concrete having a density in excess of 800 kg/m 3 [50 lb/ft 3 ].

The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design. Here, the compressive strength of concrete cylinders is determined by breaking the cylinders in a compression-testing machine.

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.

Strength of hardened concrete measured by the compression test. The compression strength of concrete is a measure of the concrete's ability to resist loads which tend to compress it. The compressive strength is measured by crushing cylindrical concrete specimens in compression testing machine.
