Research interests

Susan and her team research centres on novel cements and concretes, particularly focusing on waste management and valorisation, multi-scale infrastructure materials characterisation, durability assessment, and improving sustainability of novel cement and concrete technologies. Specifically Susan focuses on:

(i) Development, characterisation and exploitation of advanced and non-traditional cement and cement and concrete technologies, including:

• Design of bespoke cements including geopolymers and alkali-activated materials for waste management and/or valorisation.
• Determining the factors controlling phase assemblage evolution and stability of non-Portland cements, including application of thermodynamic modelling.
• Mechanisms leading to structural modifications of Portland and non-Portland cements exposed to aggressive environments, emphasising chemical/physical binding of anions/cations and structural phase transformations.
• Validation of testing methods for physicochemical characterisation of supplementary cementitious materials
• Development and validation of standardised testing methods to determine performance of alkali-activated materials

(ii) Sustainability aspects of novel cement and concrete technologies

• Waste management and valorisation for production of low carbon construction materials
• Circularity of cement and concretes integrating durability concepts
• Infrastructure for well-being

(iii) Evaluation of fit-for-purpose cementitious wasteforms for immobilisation of nuclear wastes, including:

• Chemical/physical binding mechanisms of radionuclides in cements with different chemistries
• Phase assemblage evolution and stability of Portland and non-Portland based cementitious wasteforms
• Effect of radiation in cementitious systems
