Leslie Struble Shen, Lin 2015-09-25T21:04:24Z 2015-09-25T21:04:24Z 10000-01-01 2007 2007 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 gradation, lower aggregate density, and higher paste viscosity and yield stress reduce dynamic segregation. Among these factors, aggregate size, gradation, density, and paste rheology have bigger effects than aggregate volume and initial concrete flow velocity. A simple method is introduced to set the maximum flowing distance for SCC mixes based on the flow trough result and mix proportions. Made available in DSpace on 2015-09-25T21:04:24Z (GMT).
