These ingredients are commonly combined in a 1:2:3 proportion to achieve maximum strength (1 part cement, 2 parts sand, 3 parts gravel). The amount of water used to mix the ingredients is by far the most important factor in determining the final strength of the concrete: Use the least amount of water that will still give you a workable mix .

Concrete mix ratio: The strength of concrete mixture depends on the ratio in which these four ingredients are mixed. Concrete mix ratio of 1:3:3 - On mixing 1 part cement, 3 parts sand with 3 parts aggregate produces concrete with a compressive strength of 3000 psi.
