The mean grade of M20 concrete is defined by its compressive strength of 20 MPa (megapascals) at 28 days. This grade typically consists of a mix ratio of 1 part cement, 1.5 parts sand, and 3 parts coarse aggregate by volume. M20 concrete is commonly used for structural applications where moderate strength is required, such as in beams, slabs, and columns.
