The primary emphasis of my research group is to develop fundamental kinetic and thermophysical data for materials synthesis. Materials in this case are primarily ceramics, but may include composites of ceramics, metals and polymers. While my specific focus changes from project to project, there are several themes: stoichiometry and hydration kinetics of portland cement and supplementary cementitious materials and characterization of the microstructure and transport processes in the same; synthesis kinetics and associated transport processes of ceramic materials; and kinetics of synthesis and degradation of organic materials, particularly at high temperatures, e.g. biomass pyrolysis.
Portland cement concrete is second only to water in use. This ubiquitous construction material is the very foundation of our global infrastructure. This common material has been traditionally composed of naturally occurring fine and course aggregate, Portland cement and water. Concerns over global warming and ever-increasing stockpiles of solid industrial wastes and by-products has energized efforts to develop modern concrete formulations that incorporate more waste and by-products and less portland cement. This has been beneficial from an environmental point of view, but also has the potential for improving the durability and strength of concrete. Yet, there are fundamental questions which remain unanswered and obstacles to widespread adaptation of blended-cement products. Uncertainty in the interaction between waste and by-product additives and portland cement, the stoichiometry of hydration, the chemical stability and transport properties of blended-cement concrete are of critical importance. My cements research group focuses on the kinetics of hydration, the fundamental interactions between waste and by-product materials and portland cement, the stoichiometry of such reactions and resulting microstructure and transport processes. We are applying modern analytical tools including synchrotron X-ray diffraction (XRD) and environmental scanning electron microscopy to study these complex chemical reactions in situ rather than post reaction. Existing models for cement, waste and by-product hydration are largely lumped parameter. Our ambition is to build distributed parameter kinetic models with improved predictability and reliability.
