size of concrete aggregates

EFFECTS OF AGGREGATE GRADATION ON THE
Aggregate shape, size and grading can influence concrete workability. The volumes of water and cementations materials are commonly increased to accommodate poorly shaped or poorly graded aggregates. In this work the properties of concrete in fresh and hardened stage using different aggregate sizes and mix design was investigated.

Effects of Aggregate Properties on Concrete AboutCivil.Org
Effect of Size. Variation in the size of Aggregates changes the water demand, cement content, micro-cracking (strength) in concrete. It also effects pumpability, and durability of concrete. Effect of Grading. Grading of aggregates depends on the proportions of coarse and fine aggregate.
