Aggregates Pdf Concrete Construction Aggregate Introduction • sand and gravels used for the making of mortar and concrete are called aggregates. • aggregates give body to concrete, reduce shrinkage and effect economy. • aggregates occupy about 70 80% of the volume of concrete. Classification of aggregates 1 size fine aggregate: aggregate smaller than (5 or 4.75 mm) in diameter is classified as fine aggregate or sand. coarse aggregate: aggregate larger than (5 or 4.75mm) in diameter is classified as coarse aggregate.
Aggregates Pdf Concrete Construction Aggregate Definition • aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic cement concrete, or iron blast furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar.
