We use different grades of concrete for different parts of the building. We could say the grade of concrete is the only thing we do care lot while concreting. In this post, we are going to explain that in detail. Actually, what do we mean by grade of concrete.? Concrete grades are denoted by M10, M20, M30 according to their compressive strength.
