Implementation of concrete aggregate optimization ...

2015-1-15  To account for aggregates with different specific gravities, the procedure optimizes the aggregate blend based on volume, rather than weight. To do this, the total volume of aggregate V agg is converted to an equivalent mass (weight) for use in the optimization process by multiplying V agg by the unit weight of water and a “standard” specific gravity (taken as 2.60).
