[Solved] Separation of water, sand, cement from freshly mixed …
Bleeding is sometimes referred to as water gain. It is a particular form of segregation, in which some of the water from the concrete comes out to be the surface of the concrete, being of the lowest specific gravity among all the ingredients of concrete. Bleeding is predominantly observed in Highly wet mix Badly proportion

The correct option is B Bleeding Bleeding : Bleeding is water in concrete which comes out to the surface of concrete because of low specific gravity. It is seen in highly wet concrete or badly proportional mixes. Segregation : Separation of the constituent material of concrete i.e. cement, sand and aggregate because they have different specific gravity.
