testing of concrete for compressive strength and quality

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 watercement ratio) and time and quality of the curing, compressive strength of concrete can be obtained up to 14,000 psi or more.

The ratio of the water to cement is the chief factor for determining concrete strength. The lower the watercement ratio, the higher is the compressive strength. 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.

Compression test. A compression test is one of the mechanical (strength) tests performed on materials. The compression test determines material behaviour under compressive or crushing load. The test specimen or test item is compressed and deformation at various loads is recorded on conventional graph paper or charts or computerised data acquisition.

According to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days. Why do we test at 7, 14 28 days? Concrete is a macro content with Sand, Cement, Coarse aggregate as its microingredient (Mix Ratio) and gains its 100% strength over time at the hardened state.
