Dr. Sreejith Krishnan

Profile

I am a Research Fellow in the School of Civil Engineering with a focus on the chemistry of cement materials. I am part of the MUSE (Multi-scale engineering of alkali-activated concretes for sustainable infrastructure) group led by Prof. Susan Bernal, working on developing novel low-carbon cements from activated clays. Before joining the University of Leeds, I was a post-doctoral researcher with Prof. Karen Scrivener in the Laboratory of Construction Materials, EPFL, with a Swiss Government Excellence Post-Doctoral Fellowship, where I tried to study the chemistry of belite in Portland cements. 

I received my PhD in Civil Engineering from the Indian Institute of Technology Delhi, India in 2019. My doctoral research was a part of the global  Low Carbon Cement Project funded by the Swiss Agency for Development and Co-operation. The objective of my research was to understand the hydration and microstructure development in limestone calcined clay cements (LC3) and to develop a framework for optimising the LC3 blend compositions. The thesis was supervised by Dr. Shashank Bishnoi. 

Research interests

My research interests include – 

• Development of novel characterization techniques for raw materials as well as hydrating cement systems using the latest developments in X-ray diffraction method such as PONKCS
• Utilisation of alternate raw materials in the production of portland cement
• Alternative cements and binders
• Microstructure of cement and concrete
• Durability issues in concrete
• Non – destructive testing of concrete structures
• Repair and Rehabilitation of existing structures
