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 lb; fine aggregate 9,230 lb; coarse aggregate 11,960 lb; water 1,841 lb; wet unit weight 152 pcf).
