## Grades of Concrete with Proportion (Mix Ratio) – Civilology

Concrete grades are denoted by M10, M20, M30 according to their- camelwaypressive strength. The “M” denotes Mix design of concrete followed by the- camelwaypressive strength number in N/mm2. “Mix” is the respective ingredient proportions which are Cement: Sand: Aggregate Or Cement: Fine Aggregate: Coarse Aggregate.

Concrete grades are determined by concrete's- camelwaypressive strength 28 days after it has been poured. The strength is measured in psi, or pounds per square Concrete grades are determined by concrete's- camelwaypressive strength 28 days after it has been poured.

The grades of concrete refers to the ratio by which the ingredients of concrete i.e. cement, fine aggregate (Sand) and coarse aggregate is mixed. The basic grades of concrete and its corresponding ratios of mix are given below. There are two type of mixes.

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- camelwaypression resistance after 28 days. It is done in Newtons per square millimetre. A concrete of Grade C30 means that the concrete will have a- camelwaypresion resistance (withstanding a- camelwaypression) of 30 N/mm2 per square millimetre in 28 days.
