1 part cement. In an ideal world, where everything is delivered dry, a water to cement ratio of approximately 0.55 should be used. As we have explained above, if requiring 25kg of cement in your mix, then to calulate the suggested volume of water it would be: 25 x 0.55 = 13.75kg (litres) of water.

The amount of concrete you need for a 10x10 slab depends on how thick it will be. So, for a 4-inch slab you'll need 1.24 cubic yards (56 80lb bags), but a 6-inch slab requires 1.85 yards (84 80lb bags). If your slab is a different size or thickness, use our calculator to determine the amount of concrete.

The Spruce. Cement (also called Portland cement) is a fine binding powder that is never used alone but is a component of both concrete and mortar, as well as stucco, tile grout, and thin-set adhesive. Mortar is composed of cement, fine sands, and lime; it is used as a binding material when building with brick, block, and stone.
