Kilogram-force/Square Centimeter : A kilogram-force per square centimeter (kgf/cm2), often just kilogram per square centimeter (kg/cm2), or kilopond per square centimeter is a pressure unit that has been largely displaced the SI unit system of pascal units. For finished concrete - 3,500 p.s.i. However, a good contractor who wants to avoid call-backs will use at least a 4000 psi mix for a driveway. We recommend a 6-1/2 bag mix or 4,000 PSI concrete with a 6-8% air entrainment and low slump in the 3-4“range to avoid Spalling of the surface from the winter. There are different approximate PSI's for different applications. For instance, the PSI value for car cleaning should be less than the PSI or pressure needed for cleaning those stubborn floor stains. Aggregate Mixes: The production of exposed aggregate mixes involve pumping air into the mixture to create small air bubbles in the final material. Here's what I get charged for 3500 psi concrete. I use 3000 psi concrete for: Foundation footings; Foundation walls; Residential (house & garage) Interior concrete floors; Small commercial buildings interior concrete floors It is used to reduce the dead load of concrete members, such as floor slabs in high-rise buildings.
