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.

In this study, we have used grit and crushed sand for the design mix and found the characteristic . For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the . Sp. Gravity of Crush sand Aggregate.

The water-cement ratio is the ratio of the weight of water to the weight of cement used in a concrete mix. A lower ratio leads to higher strength and durability, but may make the mix difficult to work with and form. Workability can be resolved with the use of plasticizers or super-plasticizers.
