Concrete countertops, sinks, fire features and furniture require vastly higher quality concrete than sidewalks or even foundations, in terms of both performance and aesthetics. One of the keys to the best concrete countertop mix design is to keep the water cement ratio very low. Typically concrete countertop artisans use w/c ratios of about 0.32%.

Although the words "concrete" and "cement" are used in place of the other very frequently, both are not same.Cement is an ingredient in concrete like other ingredients like aggregates, pebbles, air and water. The property of the concrete depends a lot on the proper mix ratio of concrete ingredients.

If the proportions are based on weight, use 4 pounds of coarse aggregate and 2 pounds of sand for every pound of cement. To make the concrete, though, you still need to know the required watercement ratio. If the proportions are based on volume, use four shovelfuls of coarse aggregate and two shovelfuls of sand for every shovelful of cement.
