Prof. Susan A Bernal

Profile

Susan holds the Chair in Structural Materials in the School of Civil Engineering at University of Leeds, and a prestigious EPSRC Early Career Fellowship in Multi-scale Engineering of Sustainable Concretes. Previously she was University Academic Fellow in Cementitious Materials at Leeds (2018-2019), and Research Fellow in Cements in the world leading NucleUS Immobilisation Science Laboratory in Department of Materials Science and Engineering at The University of Sheffield (2012-2018). During that period she also held a one year appointment (2015-2016) as Lecturer in Concrete Technology in the Civil and Structural Engineering Department of this University. Prior to this, she was a Postdoctoral fellow (2009-2010) with Professor Jørgen Skibsted in the iNANO Instrument Center for Solid-State NMR Spectroscopy, Chemistry Department at Aarhus University, Denmark, and she then undertook a Research Fellow position (2010-2012) focusing on durability assessment of alkali-activated concretes, with Professor Jannie van Deventer and Professor John Provis in the Chemical and Biomolecular Engineering Department at the University of Melbourne, Australia.

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) 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
