[shreyansh jain]

Well shaped aggregates have following advantages:-
1) Better shape reduces the water demand for a given mix, hence decides the
cement consumption for a given workability.
2) It improves the compactability and cohesion characteristics of green concrete.
3) It also reduces the mortar content of concrete for making concrete mixes
pumpable.
4) It reduces segregation and bleeding characteristics of green concrete.
5) It improves physical characteristics of hardened concrete including compressive
strength, flexural strength, abrasion and impact resistance of concrete.
6) It also reduces the permeability and improves the durability of concrete.
