What Is An M20 Concrete Mix Design? An M20 concrete mix is a type of concrete mix that has a compressive strength of 20 MPa. Typically, the ratio of cement to sand to stone aggregate is 1:1.5:3 ( one part is cement, 1.5 part is sand and 3 part is aggregate or stone). M20 concrete is a minimal nominal mix of concrete used in RCC …
