Calculate Cement Sand & Aggregate from Concrete Mix …
The strength of the concrete greatly depends on the density of the concrete hence we should not play with the ratio of sand to aggregate. 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.
