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
River sand is often used in concrete mixes and mortars. Some common uses of river sand include: Concrete production; Mortar mixes; Landscaping and gardening; Pit sand.
