The University of Manchester invites applications for a 3.5-year PhD project focused on integrating machine learning and carbonation treatments to develop sustainable, waste-derived cementitious materials. This research addresses the urgent need for low-carbon construction materials as the industry transitions to net zero, targeting both waste reduction and CO₂ emissions mitigation. Conventional Portland cement production is a major contributor to global CO₂ output, while vast quantities of alkaline industrial wastes—such as steel slags, incinerator bottom ash, and construction and demolition waste—are underutilised. These wastes, rich in calcium and magnesium, can undergo mineral carbonation, enabling permanent CO₂ sequestration and transformation into supplementary cementitious materials (SCMs) that partially replace Portland cement.

The project will tackle the challenge of waste variability by combining experimental carbonation treatments with advanced machine learning (ML) techniques. Experimental data will be used to train ML models that correlate waste properties, process parameters (e.g., CO₂ flow rate, solution chemistry, temperature), and cementitious performance metrics (CO₂ uptake, reactivity, strength, durability). These models will guide targeted experiments, predict material performance, and establish efficient, transferable workflows for waste treatment and utilisation. The research will generate structured datasets, validated ML models for CO₂ sequestration and reactivity prediction, and design guidelines for matching waste types to specific applications.

As part of the Manchester CREATES team (Concrete Materials, Resource Efficiency and Advanced TEchnology for Sustainability), the successful candidate will engage in interdisciplinary research at the intersection of materials science, civil engineering, and data science. The project offers opportunities to develop expertise in materials characterisation, process optimisation, and digital modelling, contributing to the advancement of circular, low-carbon concrete solutions for the UK construction sector.

Eligibility and Requirements: Applicants should hold or expect to achieve at least a 2.1 honours degree or a master’s (or international equivalent) in a relevant science or engineering discipline. A strong understanding of alternative cement binder systems, concrete sample preparation and testing, and analyses involving reaction mechanisms, mechanical performance, and microstructural development is essential. English language proficiency is required for non-native speakers.

Funding: This PhD is primarily for self-funded students. However, exceptional candidates may be considered for Faculty funding, which covers an annual tax-free stipend of £20,780 (with expected annual increases) and full tuition fees. Additional scholarships and awards may be available at university, faculty, and department levels for both UK and international students.

Application Process: Applications are accepted year-round, but early application is recommended as the advert may be removed once filled. Prospective applicants are strongly encouraged to contact the supervisor, Prof C Unluer, before applying, providing details of their academic background, experience, and motivation for the project. Applications must be submitted online, specifying the project title, supervisor, funding status, previous study details, and two referees. Required supporting documents include transcripts, CV, a supporting statement, and referee contact details. Incomplete applications will not be considered.
