How to Mix Cement Without Sand | Hunker

The basic equation for making concrete is: 60 to 75 percent aggregate material (sand or the other aggregates mentioned) mixed with 10 to 15 percent cement. The amount of water you mix in will depend on the aggregate material, but you'll want somewhere between 15 to 20 percent of water.
