Types of Aggregates

Jun 22, 2020· Aggregate interlock is created within an activated contraction joint. The broken edge below the joint is irregular enough that the aggregate that projects locks into the other side. If the joints are spaced close together (or the concrete doesn't shrink much), so that they don't open too much, aggregate interlock can be effective.

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.
