Based on the structural design requires the concrete has classified in different mix ratio. Technically the mix ratio of concrete will be mentioned as **Grades of Concrete.**

So in this post, we shall discuss the different grades of concrete and how it could differ from one grade to another grade.

## Grades of concrete?

Usually, the concrete grade was mentioned as M10, M15 etc.,

In concrete mix ratio, M represents the mix proportion of material like Cement, Sand and coarse aggregates and the number denotes its compressive strength.

#### Example

The compressive strength of concrete will take from the result of after 28 days cube test. The value of compressive strength will be measured in Mpa or N/mm^{2}

As per IS 456:2000 the different grades of concrete listed along with its compression strength.
