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 Strength of Coarse Aggregates
Strength reduction of concrete produced from recycled coarse aggregate and natural fine aggregate ranges from 5 to 24%. This influenced by strength of crushed concrete, water to cement ratio of crushed and new concrete. For concrete produced from both recycled coarse and fine aggregate is between 15 to 40%. 2.

The Aggregates which will get retained on the 4.75 mm (No. 4) sieve and will pass through a 3-inch sieve are known as Coarse aggregate. The aggregates used in the production of concrete are inert granular materials such as gravel, crushed stone, sand, slag, and recycled concrete. The aggregates might be natural, manufactured, or recycled.

Coarse or fine aggregate samples are repeatedly immersed in a saturated sodium or magnesium sulfate solution and oven-dried between cycles. Salt crystals growing in micro-fissures of the aggregate simulate the expansive forces of ice crystals throughout the cycles, and loss in mass is determined for different sieve size fractions as the particles degrade.

Provides strength. The aggregates are used as an important ingredient in the preparation of concrete. The fine aggregates are used in concrete as a filler material, and the coarse aggregates give the compressive strength to the concrete. When we estimate the concrete quantity, the aggregates will occupy 70 to 75% of the volume.

The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part- 4. The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load. To achieve a high quality of pavement aggregate possessing low aggregate crushing value should be preferred.

COARSE AGGREGATE. Coarse aggregates refer to irregular and granular materials such as sand, gravel, or crushed stone, and are used for making concrete. In most cases, Coarse is naturally occurring and can be obtained by blasting quarries or crushing them by hand or crushers. It is imperative to wash them before using them for producing concrete.
