News, Updates and Events
We have 2 exciting PhD opportunities currently advertised which tackle problems with cement sustainability by investigating alternative raw materials for manufacture and their hydration:
Full details of the project can be found using the above links. Both projects will be based in the Department of Materials Science and Engineering and candidates will join the Cements@Sheffield research group. These projects are part of the FeRICH scheme and include potential for 3 month placements at other participating institutions (see project listing for details). This studentship will pay Home tuition fees and a stipend for living expenses for 3.5 years at the RCUK rate. EU and other nationals may be eligible for Home-student fees.
Should you have any questions please contact Dr. Theo Hanein.
PhD vacancy: Cement-superplasticiser interactions in nuclear wasteforms
Are you interested in taking part in cutting edge cement research to better understand how to safely dispose of nuclear waste? This PhD opportunity may be for you! The project aims to improve understanding of cement-superplasticiser interactions in blended Portland cement wasteforms. Full details can be found here.
This interdisciplinary project spans chemical and materials engineering, being part of the Sustainable Materials at Sheffield group (in the Department of Chemical and Biological Engineering) and the Cements@Sheffield group (in the Department of Materials Science & Engineering). Furthermore, this project will work in collaboration with the National Nuclear Laboratory and Sellafield Ltd, and the PhD studentship is fully funded by the Nuclear Decommissioning Authority. The studentship is available for a student from the United Kingdom or from the European Union with 3 years residency in the UK.
Please contact Dr. Brant Walkley should you have further questions.
New paper alert
New publication time! Have you wondered how high temperature decarbonisation of calcium carbonate, a key process in the production of cement, can be mitigated to help reduce CO2 emissions? Have a read of this recent paper published in Energy and Environmental Science: Decarbonisation of calcium carbonate at atmospheric temperatures and pressures, with simultaneous CO2 capture, through production of sodium carbonate.
Hot off the back of COP26 this is a really fab piece of work, featuring a stellar Cements@Sheffield line up. Congratulations Theo Hanein, Marco Simoni, Chun Long Woo, John Provis and Hajime Kinoshita.
