Question
Concrete is required for a foundation located below ground where no substantial freezing and thawing occur. The 28-day compressive strength should be 4,000 lb./in2. The slump should be 2in. and the maximum aggregate size should not exceed 4 in. The properties of the materials are as follows: Cement : Type I, specific gravity = 3.15 Coarse Aggregate: Bulk specific gravity (SSD) = 2.82; absorption capacity = 3%; dry-rodded unit weight = 125 Ib./ft.3; surface moisture = 1%, Moisture content = 4% Fine Aggregate: Bulk specific gravity (SSD) = 2.60; absorption capacity = 1.3%; fineness modulus = 2.70; surface %3D %3D moisture = 2% Moisture content = 3.3% Compute for the estimated batch weights per cubic yard and the total in Ib/ft3
