Concrete is a widely used construction material that consists of cement, sand, aggregate, and water. The proportions of these materials determine the strength and durability of the concrete mix. In this blog post, we will discuss how to calculate the quantity of cement, sand, aggregate, and water for 1m³ of M20 grade concrete.
In conclusion the grade of concrete refers to the quality of the concrete and strength of the concrete mixture used in construction projects, also the concrete grade is denoted by a numerical value such as M7.5, M10, M20, M30 and so on and the letter "M" is stand for mix and the number represent its compressive strength of concrete in unit ...
M20 concrete grade means, M refers to concrete mix, and numerical figure 20 represents its characteristics of compressive strength (fck) @28 Days curing that is 20MPa when tested with 15cm × 15cm × 15cm cube. It is prepared by taking mix ratio 1:1.5:3 (1 cement : 1 1/2 Sand : 3 …
M20 Concrete vs. Other Grades. M20 Concrete: Grade: M20 is a lower-grade concrete mix commonly used for relatively less demanding applications. Mix Proportions: It typically consists of 1 part cement, 1.5 parts sand, and 3 parts coarse aggregates by volume, with a water-cement ratio of around 0.5-0.55.

I would suggest the ratio of 1:2:3 or 1:1.5:3 for M20 grade concrete and 1:2:4 or 1:2.5:3.5 for M15 grade concrete. If you prepare concrete with your ration then the concrete will have too much sand. Too much sand causes shrinkage and this will not give high-density concrete.
For an M20 grade of concrete, the ratio is (1:1.5:3) ie, (1 part of cement: 1.5 part of sand: 3 part of Aggregate) Let us assume for 1 Cum. Of M20 concrete, So, Wet volume of concrete = 1 Cum. Dry volume of concrete = 1.54 times of the wet volume of concrete (Here 1.54 stands. as "Factor of safety" to counter the shrinkage) = 1.54 Cum
