    The Effect of Aggregate Properties on Concrete

    Aggregate is classified as two different types coarse and fine. Coarse aggregate is usually greater than 4.75 mm (retained on a No. 4 sieve) while fine aggregate is less than 4.75 mm (passing the No. 4 sieve). The compressive aggregate strength is an important factor in the selection of aggregate.
