According to. 1 psi = 6,894.76 pascals (Pa); 1 MPa = 1,000,000 pascals (Pa); psi value x 6,894.76 Pa = MPa value x 1,000,000 Pa That means 3500 psi concrete is called a 6 sack mix or 6 bag mix of concrete. For concrete with specified strength upto 35 MPa (5000 psi), no strength test results should fall below the specified compressive strength by more than 3.5 MPa or 500 psi. Convert PSI to MPA with Chapel Steel's conversion calculator. Concreteâs flexural strength ranges between 400-700 psi (3-5MPa) whereas Belzona 4154âs is significantly higher, allowing it to bear heavier loads than traditional concrete. Each concrete structure has a normally acceptable psi range. The American Concrete Institute recognizes 28 days or âthe test age designated for determination of the specified compressive strength.â5 Therefore, when a specifier calls for 5,000 psi concrete at 28 days, this tells the concrete producer to select a mix design that will attain a minimum of 5,000 psi 28 days after manufacture.
