Cement is the most ubiquitous product after drinking water, with 4.1B tons produced in 2017 alone, enough for half a ton per person per year worldwide. Its production also accounts for 5% of man-made CO2 emissions, thus any improvement to the production efficiency will have a meaningful change to our environmental impact. Critical to the production process are the calcination and the high-temperature (~1450℃) “clinkering” reaction. The former releases CO2 contained within the limestone used as raw ingredients for the cement, whereas the clinkering reaction requires significant amounts of fuel to reach the required temperature to form the “cementicious” phases.
Nanocem, a European consortium of cement manufacturers, recently funded Core Project 17 which commissioned the University of Aberdeen along with collaborators in Grenoble, Weimar, and Sheffield to investigate the thermodynamics of high-temperature clinkering reactions. By better understanding how the formation temperature of cementicious phases are influenced by the presence of minor components, new optimisations and variations to the production process might be found.
This PhD will continue our world-leading research in this field (see cited works). The approach will be a mixture of theoretical/computational modelling of the thermodynamics of the system, along with experimental validation and data gathering. The experimental work will be supported by a PhD studentship at the Laboratoire SIMaP in Grenoble, under the supervision of Dr Alexander Pisch. Both students will spend ~6 months in each institute working collaboratively to develop the tools and information to solve this global challenge, learning high-temperature synthesis techniques and thermodynamic modelling. In addition, both students will spend ~6 months at the University of Weimar to utilise the experience and facilities of Dr Christiane Rößler and Dr Frank Bellmann, applying cutting edge electron microscopy and NMR techniques to their synthesised clinker samples. Finally, the student from Aberdeen will also spend ~3-6 months at the University of Sheffield with Dr Theodore Hanein working on volatile phase characterization.
This project requires a highly motivated student with a background in chemical engineering, chemistry, physics, or a related field. Experimental and computational techniques will be taught as part of this project but a background in process engineering, solid state chemistry, thermodynamics and/or lab experience is desirable.
