T1 - Segregation of coarse aggregates in self-compacting concrete N2 - A major requirement on self-compacting concrete (SCC) is the resistance to any kind of separation. In the presented studies the segregation behavior of aggregates was analyzed systematically. The rheology of selfcompacting mortars was dealt with at first. Following, the segregation of particles of different size, shape and density in various mortars was examined. The aim was to find an analytical relation to estimate the risk of sedimentation, using the characteristics of the particles and those of the mortars. The classification of the aggregates according to their potential segregation is rather simple. But the description of the segregation resistance of the mortar is much more difficult. It is not possible to evaluate a mortar solely based on the rheological properties. The mixture composition must always be considered as well. Tests on concrete samples were conducted additionally to determine the influence of the overall system of SCC on the sedimentation of the aggregates.
