M20
Required slump height of M20 for different concrete structures, are normally calculated by the required slump value, which would come out to be 100 lits.
The ratios of cement to sand to aggregate for the different grades of concrete are as follows. M10 has a ratio of 1:3:6. M15 has a ratio of 1:2:4. M20 has a ratio of 1:1.5:3. M25 has a ratio of 1:1:2, but M30 has no set ratio. It is a designed mixture to achieve the stress tolerance desired.
M20 Mrefers to mix and 20 refers to 20 n/mm2 strengh and M200 mix 200n/mm2

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.
