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

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. Mixing water with the cement, sand, and stone will form a paste that will bind the materials together until the mix hardens.
