Concrete is required for an exterior column located above ground where moderate freezing and thawing can occur. The 28-day compressive strength should be 4,000 lb/in2. The column dimensions are 12” by 12” with rebar spaced with 3” clear spacing and 2½ ” cover (rebar to form). The properties of the materials are as follows: Cement : Type I, specific gravity = 3.15 Coarse Aggregate: Bulk specific gravity (SSD) = 2.65; absorption capacity = 2%; dry-rodded unit weight = 98 lb/ft3; moisture content = 5% Maximum aggregate size availability: 1/2in, 3/4in, 1in or 1.5in Fine Aggregate: Bulk specific gravity (SSD) = 2.7; absorption capacity = 4%; fineness modulus = 2.50; moisture content = 6% Use Slump 3 to 4 inches, and moderate air-entraining Calculate the weights of cement, moist gravel, moist sand, and water to be added to the batch per yd3 of concrete. Find: Initial Values (by Weight / Volume for Air)
