### Concrete Mixing Ratios - How To Make Concrete (Cement, Sand ...

What is the ratio for mixing concrete? One of the best concrete mix ratios is 1 part cement, 3 parts sand, and 3 parts aggregate, this will produce approximately a 3000 psi concrete mix. The strength of this mix ratio is good for most concrete slabs, footings, steps, and foundation walls.

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. On mixing water with the three ingredients, a paste is formed that binds them together till the concrete mix gets hardened. The strength concrete is inversely proportional to the water/cement ratio.
