## The Effect of Aggregate Properties on Concrete

Aggregate is classified as two different types, coarse and fine Coarse aggregate is usually greater than 475 mm (retained on a No 4 sieve), while fine aggregate is less than 475 mm (passing the No 4 sieve) The compressive aggregate strength is an important factor in the selection of aggregateRecycled concrete aggregate (RCA) is the designation used in BS 85002 for recycled aggregate principally comprising crushed concrete Designations of recycled aggregate other than RCA are of lower quality and may contain significant quantities of masonry which would preclude or limit their use in structural concreteRecycled Concrete Aggregate an overview | ScienceDirect
