A key requirement onto the concrete properties is that during the placement process the fresh concrete needs to completely fill the formwork while staying homogeneous. Whereas substantial research onto the flow and sedimentation behavior of fresh concrete has been presented regarding highly flowable self-compacting concretes, research regarding these properties on ordinary, vibrated concretes has been missing. In the presented research thus the sedimentation behavior of ordinary concrete as well as model systems was investigated. Here it could be shown, that even concretes which are seen as stable show significant changes in their homogeneity due to vibration compaction and that these local variations in aggregate content and particle size distribution have pronounced influence on the local rheological properties of the mix. The results could be closly linked to the nanoscopic particle inventory. Further, a novel measurement technique for the rheological properties of fresh concrete was developed which relies on the inverse analysis of the flow behavior of the concrete during the discharge process of a mixing truck. Using so-called Computer Vision Methods, video images of the concrete flow process can be used to derive rheological parameters such as the yield stress of the plastic viscosity.
