For example, for a grade of concrete with a strength of 20 MPa, would be denoted by M20, where M stands for Mix and 20 is the overall strength of the concrete in Newton. Major ingredients of concrete are binding material (like cement, and lime), fine aggregate (sand), coarse aggregates (crushed stone, jelly), and water.

The compressive strength of hardened concrete is determined by using a compression testing machine after either seven days or 28 days of curing. The load is applied gradually at a rate of 140 kg/cm2 per minute until the specimens fail. The compressive strength of the concrete is determined by dividing the load at failure by the specimen's area.
