This video shows the grades of concrete mix. Concrete is a composite material made up of cement, water, fine aggregate and coarse aggregate. Concrete strongly depends on w/c ratio, if increasing the w/c ratio strength going to decrease and if decreasing the w/c the strength going to increase. Concrete grades are represented by M following by a number like M20, Where M shows concrete mix and 20 shows the concrete compressive strength in MPa. For more details please watch full video.
