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.
how much tensile strength of M20 grade concrete at 28 Days
Yes. OPC 43 grade cement can be used to make M20 grade concrete.It can be used to make concrete up to M30 Grade.See related link.

M20 refers to the grade of the concrete generally used in construction purpose. Here, M refers to mix & number 20 refers to the characteristic strength of concrete. the proportions of this grade is (1:1 1/2: 3). Along with this there are some more grades used in constructions i.e., M5, M7.5, M10, M15, M25, M30................. M80
