Research assistant (m/f/d) - Hydration, Microstrukture und Dimensional stability of M-S-H-binders

Institut für Baustoffe, Massivbau und Brandschutz, FG Baustoffe

With around 15,000 students and 3,800 employees, the Technische Universität Braunschweig is one of Germany´s leading institutes of technology. It stands for strategic and performance-oriented thinking and acting, relevant research, committed teaching, and the successful transfer of knowledge and technologies to the economy and society. We consistently advocate for family friendliness and equal opportunities.

Our research focuses are mobility, engineering for health, metrology, and city of the future. Strong engineering and natural sciences are our core disciplines. These are closely interconnected with economics, social and educational sciences and humanities.

Our campus is located in the midst of one of the most research-intensive regions in Europe. We work successfully together with over 20 research institutions in our neighborhood as we do with our international partner universities.

Starting from 1st June 2026 the Institute of Building Materials, Concrete Construction and Fire Safety, Division of Building Materials, is looking for a

**Research assistant (m/f/d)

Hydration, Microstructure and Dimensional stability of M-S-H binders**

(EG 13 TV-L)

The position is initially limited to one year, with the aim of continuing employment for another two years. The position is an employee position. The fixed-term employment is within the scope of the fixed-term employment options provided for in the German Academic Fixed-Term Contract Act (Wissenschafts-zeitvertragsgesetz).

The researcher will be part of international, multi-disciplinary team of researchers at TU Braunschweig, RWTH Aachen University, and TU Dresden.

The team of the Division of Building Materials at TU Braunschweig, focuses on understanding and predicting the hydration behaviour of eco-efficient binders. Within the working group of Microstructure and Modelling, we are looking for a talented individual to work on a project revolving around the hydration, microstructure and dimensional stability of M-S-H binders. Within the scope of the project, different types of M-S-H binders on paste will be developed and characterized on a fundamental scale. The research activity would span multiple lengths and time scales, utilizing laboratory experimental techniques (i.e., XRD, TGA, microscopy), as well as advanced synchrotron facilities. Thermodynamic modelling will also be used to predict phase composition. Besides structural investigations, dimensional stability will be assessed through variations in drying shrinkage. Carbonation progress of mortars/pastes as well as changes in the pore structure of samples subjected to wet and dry carbonation will be assessed.

Your tasks

Production of M-S-H binders via a variability of raw materials, followed by detailed assessment of their mechanical, mineralogical, and microstructural properties.
Analysis of large sets of data obtained at synchrotron facilities.
Present research findings at national and international conferences.
Supervision of master student projects and potential contribution to teaching activities.

Your Qualifications

A completed graduate degree (master’s degree or equivalent) in civil engineering or a related field (e.g., materials science, mineralogy)
Prior knowledge of the microstructural evolution in hydrating eco-efficient cements is desirable but not essential.
Ideally, prior practical experience with microstructural characterization techniques such as XRD will be beneficial.
Excellent proficiency in English, both written and spoken.
Flexibility and willingness to collaborate in a dynamic and diverse team. An open approach to work across disciplines and the ability to communicate ideas constructively are essential.

We offer

Work on exciting future-oriented research topics in an inspiring and diverse work environment as part of the university community
A vibrant campus life in an international atmosphere with lots of intercultural offers and international cooperations
Fulltime-job, pay in accordance with the collective agreement TV-L (a special payment at the end of the year as well as a supplementary benefit in the form of a company pension, comparable to a company pension in the private sector) including 30 days' vacation per year
Employee benefits portal for TU Braunschweig staff featuring attractive offers from leading brands
Flexible working and part-time options and a family-friendly university culture, awarded the "Family-friendly university" audit since 2007
Special continuing education programs for young scientists, a postdoc program, as well as other offerings from the Central Personnel Development Department and sports activities.
