Properties of Aggregates aggregate affects on the strength and durability of the concrete. Aggregate is a broad encompassing boulder, cobbles, crushed stone, gravel, air-cooled, blast furnace slag, native and manufactured sands, and manufactured and natural lightweight aggregates.
Crushed concrete aggregates also called as recycled concrete aggregates are fragments and pieces of concrete buildings which are demolished or rebuild. These crushed concrete are cleaned from dirt and broken to smaller pieces to manufacture aggregate which is termed as recycled aggregate. Crushed concrete aggregate eliminates the need for disposal by using the readily available
Thus rougher the surface as that of a crushed stone, better the bond. Secondly bond is also affected by other physical and chemical properties of aggregate. The determination of bond strength of aggregate is difficult and no accepted test exists. It is judged by the surface of a crushed concrete.

On wet roads a sufficiently rough surface texture on the macroscale is necessary to ensure rapid removal of water from the contact zone between the tire and road surface, especially at high speeds. For this surface texture on the macroscale, beside the particle size of the aggregate also the resistance to crushing and abrasion is rather important. The macroroughness is likely to decrease ...

The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 30-40. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and
