To calculate the amount of sand and metal (aggregate) in M10 and M20 grades of concrete, you first need to determine the mix ratio. M10 is typically a 1:3:6 ratio (cement:sand:aggregate) and M20 is a 1:1.5:3 ratio. For a given volume of concrete, calculate the total parts in the mix, then divide the total volume by the sum of the parts to find the volume of each component. Finally, multiply the volume of sand and aggregate by their respective mix ratios to find the quantities needed.
Concrete mix is made from (sharp)sand, cement, aggregate and water. The ratios depent on the usage

In this M refer to Maximum compressive strength and 20 refer that concrete that with stand upto 20KN compressive strength.
For nominal Mix Cement consumption for M25 will be 570 kg per cum. and for Design Mix it can be optimised to 510 kg per cum.

it is concrete mix which gain strength 20kn/mm2 in 28 day of curing....

M20 refers to the grade of the concrete generally used in construction purpose. Here, M refers to mix & number 20 refers to the characteristic strength of concrete. the proportions of this grade is (1:1 1/2: 3). Along with this there are some more grades used in constructions i.e., M5, M7.5, M10, M15, M25, M30................. M80
M20 Mrefers to mix and 20 refers to 20 n/mm2 strengh and M200 mix 200n/mm2
M20 grade - 1:1.5:3Cement required - 360 kgs per m3Cement required - 7.2 bags.
does not exceed 30N/mm2
