Determine a mix design that meets the following criteria: a. Target strength: 4,000 psi b. Target slump: 2 inches c. Moisture content (FA) = 8 percent d. Absorption content (FA) = 3 percent e. Moisture content (CA) = 3 percent f. Absorption content (CA) = 1 percent g. Fineness modulus of CA = 2.6 h. Dry-rodded unit weight of coarse aggregate: Select a value based on the class data gathered in lab 1 or assume 97 lb/ft³ i. Specific gravity of cement, fine aggregate and coarse aggregate = 3.15, 2.65, and 2.68 respectively The concrete is to be used for an approach slab in Northern New York which has dimensions of 10 ft wide by 20 ft in length and thickness of 8 inches. Reinforcement is placed with a clear spacing of 8 inches in the longitudinal direction and 12 inches in the transverse. In determining the amount of concrete needed for the slab you may neglect the reinforcing bar and only use the 10ft x 20ft x 0.67ft slab dimensions. You should complete a mix design that includes the batch weights of cement, fine aggregate, coarse aggregate and water. Include the estimated water cement ratio, amount of entrained air and slump in this design. Use the guidelines put forth in Civil Engineering Materials, 2nd Edition by Somayaji on pages 165-175. Make sure you adjust the amount of water batched for the mix to account for the moisture condition of the aggregates.
