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. Hence use 1:2:3 for good strength and 1:2.5:3.5 for moderate strength.
