What is the mix ratio for grade C30 concrete? .

The strength of a concrete mix is measured in grades. There are different concrete grades for example C15, C20, C25, C30. The grade of the concrete means the concrete compression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C30 means that the concrete will have a compresion resistance .
