M stands for mix.Mix represents concrete with designated proportions of cement, sand and aggregate.And the number following m represents compressive strength of that concrete mix in nmm 2 after 28 days.For example, for m20 grade of concrete mix,.
The final mix proportions of m-20 grade of concrete become- note 1 the above recommended mix design must be verified, by actual cube tests.2 the mix design is based on the quality and grading of the materials actually supplied, by.
Concrete mix design is the process of detrmining right proportions of cement, sand and aggregates for concrete to achieve target strength of concrete.The advantages of concrete mix design is that it gives the right proportions of materials, thus making the concrete use economical in achieving required strength of structural members.
