Jun 21, 2019· Each 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.
Let us be clearer with an example of M25 grade concrete mix ratio. The proportions of cement in M25 grade of concrete is as follows:- 1 part of cement, 1 part of sand or fine aggregates, 2 parts of coarse aggregates, and Required quantity of water. Mixing the cement, sand & aggregates in the following proportions will result in M25 grade concrete.
