The definition of segregation and the manifestations of concrete segregation

Concrete segregation means that the amount of pumping agent or water consumption exceeds the saturation point of the cementitious material, resulting in a reduction in the resistance between cementitious material particles and accelerated displacement. Phenomenon. The phenomenon of concrete segregation is: when the concrete uses too much water and the mixture is piled up, slurry will leak out from the surface of the mixture and flow out to the edge, with stones exposed on the surface, and the surface of the stones will not stick to the mortar; when the concrete admixtures are excessively mixed, The sand and gravel sink close to the bottom plate and are difficult to shovel with a shovel. This phenomenon is also called "scraping the bottom." </p
