grading of aggregates aggregategrading the

Grading of Aggregates.Grading of Aggregatesis one which is made up of stones of different sizes, ranging from large to small (inclusive of sand) so as to have minimum of air voids (and that will have maximum density) when mixed together.Ingrading of aggregates, the voids in the mixedaggregatewould be minimum when the sand is just sufficient to fill the voids in the coarseaggregate

Aggregateis 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. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarseaggregates. Those particles passing the 9.5 mm (3/8 inch)
