the effect of mixing stones in sand

How Does the Ratio of Sand to Cement Affect the …

A pretty standard recipe for mixing concrete calls for one part of cement to every two parts of sand. The result of this recipe, assuming that four parts of gravel are also included in the mix, is a C20-rated concrete. Concrete is rated on a number system that indicates how strong the mix is after it has cured for approximately a month.
