A concrete batch calls for the following quantities per cubic yard of concrete, based on saturated surface-dry conditions of the aggregate. Determine the required weights of each solid ingredient and the number of gallons of water required for a 6.5-cy batch. Also determine the wet unit weight of the concrete in pounds per cubic foot ( cement, 3,666 lbs; fine aggregate, 9,230 lbs; coarse aggregate, 11,960 lbs; water, 1,841 lbs; and wet unit weight, 152 pct).
