What does concrete segregation mean? Hubei concrete segregation agent manufacturer, which anti-segregation agent in Hunan is effective?

Concrete segregation refers to the phenomenon 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 uneven internal composition and structure. It usually manifests as The coarse aggregate and mortar are separated from each other. The reasons for segregation may be improper pouring and vibration, the maximum particle size of the aggregate is too large, the proportion of coarse aggregate is too high, the content of cementitious materials and fine aggregate is low, and the density of coarse aggregate is higher than that of fine aggregate. If it is too large, or the mixture is too dry or too thin, the use of mineral admixtures or air-entraining agents can reduce the tendency of segregation.
