Nov 01, 2018 The strength of concrete is divided into twelve grades such as C7.5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55 and C60. Concrete mix ratios are expressed in two ways: one is expressed in materials used per cubic meter of concrete (Water: Cement: Sand: Gravel), and the other is expressed as a ratio of various materials. for example, C:S:G
