For example, consider a concrete mix design that calls for 282-pounds of water i.e. free-water and contains 1100 pounds of fine aggregate and 2000 pounds of coarse aggregate. The mix design shows fine aggregate absorption to be 2 and coarse aggregate absorption to be 1. The batch plant operator measures the aggregate moisture and finds

Nov 01, 2015 Aggregate Planning is a marketing operational activity to the organisation to balance long term business strategic planning with short term production success so that the total cost of operations of an organisation is kept to the minimum over that period. The Aggregate Planning typically covers 3 to 18 months period of time that is used in a manufacturing environment, determines overall
