Knowing the necessary compressive strength is one of the most important factors to consider when ordering ready-mix concrete. On footings and slabs on grade, reinforced concrete ranging from 3,500 to 4,000 psi is typically used; suspended slabs, pillars, and girders need between 3,500 and 5,000 psi; and walls and columns need between 3,000 and 5,000 psi.
Different strengths will be needed when non-reinforced concrete is used. For footings and walls, a concrete strength of 2,500 psi may be sufficient, whereas pavements need a concrete strength of 4,000 to 5,000 psi. Outdoor concrete for home improvements should have a strength of 3,500 to 4,500 pounds per square inch.
At Filmix Concrete Industries Incorporated, we offer a wide range of concrete strength from 1500 to 8000 PSI.
