# Different Grades of concrete

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/mm2

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