A concrete mix design requires each cubic yard of concrete to have 1800 lbs dry coarse aggregate (density 4400lb/yd3), 615 lbs cement (density 5300lb/yd3), 320 lbs water (density 1680 lb/yd3), and 6% air. The available aggregates are: coarse aggregate with moisture content of 3.0%, absorption = 1.7%, fine aggregate with moisture content of 3.3%, absorption = 1.9%. Calculate a. Required weight of coarse aggregate b. Required weight of fine aggregate (density 4250 lb/yd3) c. Required weight of water

Concrete is required for an interior concrete column in a commercial building in Corvallis, Oregon. A specified compressive strength, f’c , of 4000 psi is required at 28 days using an ASTM C 150 Type I. The design calls for a minimum of 3 in. of concrete cover over the reinforcing steel. The minimum distance between reinforcing bars is 2.5 in. A slump of 4 inches should be the target. No statistical data on previous mixes are available. Follow mixture...
