Abstract: Aim of this study is to get a deeper understanding about the correlation between the particle properties of the raw materials and the rheological properties of fresh concrete. The determination of yield stress for Self-Compacting Concrete is crucial in order to ensure form-filling abilities. The requested slump flow can be obtained by optimizing particle packing according to the Compressed Particle Model (CPM) or any other preferred model. Data from particle packing, water-cement ratio, micro mortar volume and yield stress of the micro mortar will result in a requested slump flow, which can be further adjusted by adding additional micro mortar to the mix, or by changing the rheological values of the micro mortar.
