Aggregate in Concrete - The Concrete Network

Fine aggregate should fall within gradation limits provided in ASTM C 33, Section 6. 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 coarse-aggregate gradation ranges are listed in Table 2 of ASTM C 33. These
