Role of Aggregate Packing in Segregation Resistance and Flow Behavior of Self -Consolidating Concrete
A numerical model based on rheology and mechanics analysis is developed to predict dynamic segregation. The calculated dynamic segregation agrees well with values obtained in the laboratory, using the flow trough, and in the field. It is found that smaller aggregate size, continuous aggregate …
