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 of concrete. the compressive strength of concrete is defined as the maximum crushing stress can withstand by the concrete. you may aware of concrete cube test but you may have some question like why this test conducting or any other question.
the above test result represents the "splitting tensile strength" of concrete that varies between 1/8 to 1/12 of the cube compressive strength. ok. so at its lowest the tensile strength of un u.s. dollar's strength makes travel to europe a bargain

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.

overall strength of a structure such as flexural resistance and abrasion directly depends upon the compressive strength of concrete. according to wikipedia compressive strength of concrete is defined as the characteristic strength of 150mm size concrete cubes tested at 28 days.
