An important and growing use for lime is in the production of precipitated calcium carbonate (PCC), which is used in the production of paper, paint, ink, plastic, and rubber. The paper industry uses lime as a causticizing agent and for bleaching and, increasingly, for producing PCC for use in the paper manufacturing process. Crushed Rock 9-2

Batching is the process of measuring concrete mix ingre-dients by either mass or volume and introducing them into the mixer. To produce concrete of uniform quality, the ingredients must be measured accurately for each batch. Most specifications require that batching be done by mass rather than by volume (ASTM C 94 or AASHTO M 157).

Aggregate production functions are reduced-form relationships that emerge en-dogenously from input-output interactions between heterogeneous producers and factors in general equilibrium. We provide a general methodology for analyzing such aggregate production functions by deriving their first- and second-order properties.

The job of production planning is to match forecasted demand with available capacity. If capacity is inadequate, it can usually be expanded, but at a cost. The company needs to determine if the extra cost is worth the increased revenue from the sale, and if the sale is consistent with the strategy of the firm. Thus, the aggregate production plan
