Grades of Concrete Based on Australian Standard 4000 PSI concrete is used for heavy traffic pavement, heavy use floor slabs like shops and warehouses, and concrete footings designed to support heavy loads. One of the most important factors before ordering ready-mix concrete is knowing the required compressive strength.Typically, reinforced concrete ranging between 3,500 to 4,000 psi is used on footing and slabs on grade; between 3,500 to 5,000 psi on suspended slabs, beams and girders; and walls and columns normally require between 3,000 to 5,000 psi. It, however, does not necessarily mean that every C30 grade concrete will carry stresses exactly equal to 30 MPa. Relationship between concrete strength according to time is not linear, it means increasing strength is not increases according to applied load as time increases,it will increase in nonlinear. Modulus of Elasticity of Concrete can be defined as the slope of the line drawn from stress of zero to a compressive stress of 0.45f’ c. As concrete is a heterogeneous material. & 30 cm height cylinder in a direct compression test. M25 1 : 1 : 2 25 MPa 3625 psi. The strength of concrete greater than 70 MPa is classified into high strength concrete. 1.6. I have found over in Asia on project specific batch plants that one might have a 3000 psi mix design but when the concrete is tested at 28 days, it'll be 4000 or more from time to time and usually always more than 3500.
