Aggregate in Concrete The Concrete Network

If there is a deficiency in a locally available fine aggregate, concrete may benefit from the addition of air entrainment, additional cement, or a supplemental cementitious material (SCM) to address these shortcomings. Broad coarseaggregate gradation ranges are listed in Table 2 of ASTM C 33.

Effect of Aggregate Size and Gradation on Compressive

Aggregate gradation plays an important role in concrete mixing. Unsatisfactory gradation of aggregates leads to segregation of mortar from the coarse aggregates, internal bleeding, need for chemical admixtures to restore workability, excessive water use and increased cement use [3]. Coarse aggregates constitute about 50 to 60% of the concrete
