Gradually stir in the mix and the remaining water. Use a trowel or paddle to turn the mortar mix by hand. This can take five to 10 minutes. To mix the mortar more quickly and easily, use a paddle mixer or a power drill with a paddle attachment. Run the drill at a low rate per minute until the mix is thoroughly blended.

Crushed stone often has an angular and jagged edge because of the crushing process. Gravel, on the other hand, typically has a very smooth texture and surface because of the natural weathering and wear of being exposed to running water. Unlike crushed stone, gravel is usually sold and used in its natural state.

Concrete is characterized by the type of aggregate or cement used, by the specific qualities it manifests, or by the methods used to produce it. In ordinary structural concrete, the character of the concrete is largely determined by a water-to-cement ratio. The lower the water content, all else being equal, the stronger the concrete.
