Inorganic Materials Group

Welcome

The Inorganic Materials Group conducts research to develop a fundamental understanding of the relationship between chemistry,microstructure, performance, and service life of conventional and innovative concrete construction materials, and other inorganic building materials. This work, involving the synergetic combination of experimental and computational materials science research, will enable the acceptance of new materials and will help the U.S. construction industry be competitive in advanced concrete materials and construction. The research is being coordinated with industry, voluntary standards organizations, trade associations, and federal and state government agencies.

 

Exploratory Projects (2015)

Cement Hydration Research- A collaborative effort supported by the U.S. Federal Highway Administration and involving multiple university research groups, this project is building fundamental understanding and next-generation modeling of the basic chemical, physical, kinetic, and nanostructural phenomena that determine how concrete binders hydrate, set, and develop strength.

Modeling Flow Turbulence- There are many important processes that involve turbulent flow of suspensions in confining geometries including flow of oil-sand slurries in metal pipes and mixing flow in bio-reactors. For this exploratory research project, the feasibility of developing a multi-scale model of turbulent suspension transport in confined geometries will be investigated using a novel approach called Smoothed Particle Hydrodynamics
