  • Concrete: The Basic Mix

    Concrete: The Basic Mix

    Another "old rule of thumb" for mixing concrete is 1 cement : 2 sand : 3 gravel by volume. Mix the dry ingredients and slowly add water until the concrete is workable. This mixture may need to be modified depending on the aggregate used to provide a concrete of the right workability. The mix should not be too stiff or too sloppy.

    Place the cone beside the pile of concrete. The pile should be about 1/2 to 3/4 the height of the cone for a concrete mixture with good workability. (SEE DIAGRAM) To strengthen samples and to promote hydration, soak concrete in water (after it is set). Wet sand may carry considerable water, so the amount of mix water should be reduced to compensate.
