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%.
