A multi-scale approach for modeling suspensions composed of particles with a wide size distribution, like cement based materials, is described. This multi-scale approach divides the suspension into fluid components that are identified by a characteristic solid inclusion size in each fluid. Measured or modeled rheological properties, from a characteristic fluid associated with one length scale, may be used as input to model the flow at the next larger scale. Results are presented that indicate how this approach can be useful for developing critical insights into mechanisms that control the rheological properties of cement based materials and improve interpretation of physical measurements.
