Mixing water with the cement, sand, and stone will form a paste that will bind the materials together until the mix hardens. The strength of the concrete, after it cures, will be inversely proportional to the water/cement ratio. Basically this means the more water you use to mix the concrete (very fluid) the weaker the concrete mix.
