Generally, when the stone ratio is more than the sand, this concrete cures a little stronger than a 1:3:3 ratio. The difference is in the workability of the concrete. The sand tends to make the concrete a little more easier to work with. The less sand the rockier the mix is going to be. Cool things you can make by mixing your own concrete
