More vibration more chances of segregation Poorly proportioned mix has more chances of bleeding or segregation Longer the distance, more chances that concrete mix will be segregated The various parameter along with effects are tabulated below: In the case of segregation, the heavy aggregate particles settle down leaving a sand cement mix on top affecting the quality adversely. Segregation: Segregation of concrete is the separation of ingredients of concrete from each other. It seriously affects the durability and strength of concrete. Bleeding: Bleeding is one form of segregation, where water comes out to the surface of the concrete, being the lowest specific gravity among all the ingredients of concrete.
