PROPERTIES OF AGGREGATES FOR CONCRETE Civil Engineering

These materials can be supplied in either coarse or fine-aggregate sizes. Fine aggregates have 100% of their material passing the 10 mm sieve. Coarse aggregates have the bulk of the material retained on 4.75 mm sieve. Aggregates comprise the greatest volume percentage in portland-cement concrete, mortar, or asphaltic concrete.
