Aggregate demand is expressed as the total amount of money spent,
For workable concrete, a higher water cementitious ratio is typically required when aggregate becomes more angular and rough textured. The presence of air, certain pozzolans, and aggregate proportioning will work to lower the water cementitious ratio; however the most significant reduction in water demand comes through the use of a high range waterHigh-Performance Concrete, Chapter 17 - Memphis,Optimally graded aggregate Improve workability and reduce paste demand Table 17-2.
