the segregation of concrete is that the cohesion between the components of the concrete mixture is insufficient to resist the sinking of the coarse aggregate, and the components of the concrete mixture separate from each other, resulting in the phenomenon of uneven internal composition and structure. it usually manifests as the separation of coarse aggregate and mortar from each other, for example, dense particles are deposited at the bottom of the mixture, or the coarse aggregate is separated from the mixture as a whole.
