Introduction: We can find characteristics of concrete with the single compressive strength of the concrete cube test. With this single test, one can find whether concreting is done properly or not. For general construction work, concrete compressive strength varies from 15 Mpa (2200Psi) to 30 Mpa (4400psi) and even higher in commercial and industrial structures.

Compressive strength testing of concrete:- The test is carried out using 150mm concrete cubes on a Universal testing machine or compressive testing machine. Apparatus As per IS: 516-1959 Compressive testing machine (2000Kn),15cm×15cm×15cm steel cu...
