2. Prestressed Concrete Girders. The nominal 28-day concrete compressive strength (ƒ' c) is 7.0 ksi. Where higher strengths would eliminate a line of girders, a maximum of 10.0 ksi can be specified. Slab girders should be limited to 8.0 ksi. The nominal concrete compressive strength at release (ƒ' ci) is 6.0 ksi. Where
