Types of Concrete Mix Ratio Design and their Strengths
Concrete mix is known as mixing cement with sand, stone/aggregates and water into a paste form that can be used to bind the building materials together.
The right proportion of cement, sand, stones or aggregates mixing determines the concrete max strength. There is some variety of concrete available in the market based on these ratios like M10, M20, M30, M35.But people does not know differences of M10 or M20.
“Mix” is known as “M”. Concrete with designated proportions of cement, sand and aggregate is represented as mix. And the number following represents the compressive strength of that concrete mix in N/mm2 after 28 days is determined by number designated after “M”.
The concrete mix of M20 grade will determine 20 N/mm2 of compressive strength after 28 days.

2whello, very interesting, what is the particle size of aggregates here (range in mm)?
