Workability: concrete can be place and consolidate without bleeding or segregation.
Setting of Concrete: The hardening before its hydration or it gains strength.
Hydration : During evaporation of water from concrete releases high heat of hydration. The heat may harm ful and may also produce shrinkage, resultant cracks. This can be avoid by water curing to sustain a suitable temperature and moisture in concrete.
Air entrainment : reduces the density of concrete and consequently reduces the strength.
Segregation : separation of materials. There are few types:
Separate settling of aggeregate from rest of concrete.
Separation of the paste from aggregate.
Separation of water from the materials
