Resolving reaction mechanisms, kinetics and mass transport in radionuclide-loaded geopolymer cement wasteforms

This project aims to provides greater understanding of geopolymer reaction, setting and hardening, by investigating fundamental particle interactions, so that robust specifications can be developed, and geopolymer wasteform properties and performance can be predicted. The project also aims to assess mobility of fission products, and establish chemical durability and radioactive waste retention.


Understanding Reaction Mechanisms, Kinetics and Structural Evolution in Low-Carbon Cements

This project aims to reveal the composition-structure-property relationships, reaction mechanisms and kinetics in these low-carbon cements produced from industrial wastes and low-carbon activators, using an array of state-of-the-art characterisation approaches.


Life Cycle Assessment of Sustainable Cement

This cross-disciplinary PhD project aims to develop a new material chemistry circularity comparative framework for sustainable cement for construction and energy sectors. It will perform a hybrid life cycle analysis (LCA) of AAC/AEAC produced from both traditional and non-traditional raw materials, in a system defined in space and time, and compare the environmental and economic performance of these low-carbon cements against traditional Portland cement.
