Concrete is required for a bridge deck in Chicago. A specified compressive strength, f’c, of 4,500 psi is required at 28 days using Type I cement. The design calls for a minimum of 2.5 in. of concrete cover over the reinforcing steel. The minimum spacing between steel reinforcement is 5 in. The concrete should be designed to overcome all the environmental conditions encountered in Chicago. Refer to Textbook Chapter 12 of PCA – Design and Control of Concrete Mixes. Use the absolute volume method to design the concrete mix per 1 cubic yard. The materials
