- Course: Civil engineering materials PhD
- PhD title: The use of alum water treatment sludge waste as a supplementary cementitious material
Mubarak Shamaki is pursuing a PhD at Leeds as part of the materials and structures division of the Cities, Infrastructure and Energy research group. A grant from Nigeria funds his research, which seeks to find a sustainable alternative to current cement materials to mitigate its effects on the environment.
Extracting sludge waste to make a sustainable cement
Mubarak’s research involves evaluating the physical, chemical and mineralogical properties of alum sludge waste, and assessing its impact on the hydration and performance of blended cement systems.
“My research was motivated by my vision for a sustainable cement industry through the use of alternative materials,” Mubarak said.
“The impact on the environment as a result of current practices in producing materials such as cement is vast, so I am passionate about making a contribution towards saving the world by investigating new alternative materials.
He added: “The aim of my research is to provide an alternative to the current practice of Portland cement production and its related greenhouse effects.”
My research was motivated by my vision for a sustainable cement industry through the use of alternative materials.
Funding to develop resilient infrastructure in Nigeria
Mubarak works with a research institute in Nigeria to carry out his work. He said:
“My research is part of their aim towards achieving sustainable infrastructure in Nigeria. My PhD is funded by the Petroleum Technology Development Fund (PTDF) of Nigeria.”
Civil engineering materials research team
Mubarak explained that his research topic was chosen after discussions with his supervisors, who provided invaluable support. He said:
“I am part of the civil engineering materials research unit. This research group offers an avenue for group discussions to address any needs we may have as postgraduate researchers, including laboratory needs and technical support.
My supervisors are very supportive and our research interests are aligned with the common aim of developing resilient materials.
“The Doctoral College brings together all the support services and opportunities to enhance my research,” he added.
Leeds – a bustling intellectual community
“I chose to pursue a PhD at Leeds University because it is a reputable university offering impressive technical and intellectual resources,” Mubarak said.
He added: “The city of Leeds is very comforting with so much to experience including culture, history and all kinds of entertainment.”
Leeds is... a reputable university offering impressive technical and intellectual resources.
Mubarak outlined his future plans both in the short and long term. He said:
“I intend to work in the civil engineering industry while working as a part-time lecturer.
“I will continue to provide insight on the underlying science that will inform the potential use of waste from the water industry as a cementing material.”
