Segregation of Concrete: Types, Causes, Preventions

The segregation of concrete is the separation of cement paste and concrete aggregates from each other during handling and application. Segregation is also occurred by over-vibration or compaction of concrete, in which cement paste comes to the top and aggregates settle at the bottom.. Good concrete is one in which all materials are correctly distributed to form a homogeneous mixture.
