Mixing of granular materials, slurries, suspensions, and cement Melany Hunt Department of Mechanical and Civil Engineering, Caltech Flows particulate materials are ubiquitous in nature and industry. Predictions of flow rates and mixing times rely on an understanding of the rheological properties of the materials, which can differ considerably from that associated with a single-phase material. This presentation highlights some unique features of granular materials and inertial suspensions and describe recent work at Caltech. The presentation overviews new work related to the mixing and gaseous diffusion in cement. Cement production releases significant amount of carbon dioxide, which can be reabsorbed into cement; however, the process is limited by the diffusion through the multiphase material, which can be accelerated by the mixing CO2 with the cement paste.
