Question

For the aggregate data provided please perform the Trial Mix Design by absolute volumes.Follow the work sheets we used in the class lecture to determine mix proportions meeting thefollowing criteria.

A preliminary concrete mix is required for a bridge deck in Lake Tahoe, CA. A Type 1 cement will be used. The deck will be exposed to the exterior hence the recommended air entrainment will be for the severe climate of Lake Tahoe. The mix design strength is 4500 psi. The minimum deck dimension is 12 inches and the minimum space between reinforcing bars is 2.5 inches. For the Coarse aggregate the Bulk Specific gravity is 2.7, the absorption capacity is 2.5%, the moisture content is 5.3%, and the dry rodded weight is 110 pcf. For the Fine aggregate the Bulk specific gravity is 2.9, the absorption capacity is 4.6%, the moisture capacity is 3.8%, and the Fineness Modulus is 2.7. Also provide a statement for this project on how the mix would differ based on location and minimum spacing requirements.
