The definition of concrete segregation and the manifestations of concrete segregation

Concrete segregation refers to a situation where the amount of pumping agent exceeds the saturation point of its cementitious material, resulting in a reduction in the resistance between cementitious material particles and accelerated displacement. The phenomenon of concrete segregation is: when the concrete mixture is piled into a pile, the fluidity of the mixture is very good. Within one minute or a little longer, the slurry will secrete from the surface of the mixture and flow out to the edge, and the surface will be exposed. Pebbles, and there is no mortar on the surface of the pebbles. The sand and gravel sink close to the bottom plate and are difficult to shovel with a shovel.
