Understanding Concrete Grades . Based on strength, concrete is classified into different grades like M5, M7.5, M10, M15, M20 etc. In concrete grades, the letter "M" stands for "Mix" and the following number stands for characteristic compressive strength of concrete in 28 days in the Direct Compression test.

Learn MoreThe grade of concrete is the minimum strength that the quality controlled concrete posses after 28 days of the construction. There are different grades of concrete like M15, M20, M25, M60, etc. For small scale constructions; normal grade concretes like M15, M20 & M25 are used.

Learn MoreEach grade of concrete represents some mix ratio. In general there are two types of concrete mixes such as nominal mix and design mix. The nominal mixes are those whose mix ratio is defined which includes grades of concrete up to M25. Below table shows the different grades of concrete falling under nominal mix.
