Help Shape the Future of Sustainable Construction Materials

Are you passionate about scientific research and eager to contribute to the decarbonization of the construction industry?

As a PhD Researcher (f/m/d) – Microstructure and Performance of Low-Carbon Composite Cements , you will join Heidelberg Materials' international Research & Development team while pursuing your doctoral degree in collaboration with the Karlsruhe Institute of Technology (KIT; German: Karlsruher Institut für Technologie) . Your research will focus on next-generation low-carbon cements and explore how their microstructure influences strength, durability, and overall performance.

This is a unique opportunity to combine academic excellence with real-world industrial impact and contribute to the development of more sustainable construction materials.

Your place of work will be Leimen, nearby Heidelberg, Germany.

YOUR NEXT CHALLENGE

Modern low-clinker cements are essential for reducing CO₂ emissions, but their behavior is significantly more complex than that of conventional cements.

In this PhD project, you will investigate how hydration products shape the microstructure of cementitious materials and how this microstructure influences properties such as strength, stiffness, and porosity. Your work will help establish a scientific basis for designing stronger and more sustainable low-carbon binders.

Your Responsibilities

Conduct original doctoral research in collaboration with KIT

Design and perform experimental studies on modern composite cement systems

Analyze and interpret scientific data to understand structure-performance relationships

Investigate the influence of hydration products, pore structure, and microstructural development on mechanical performance

Evaluate the effects of supplementary cementitious materials (SCMs), fillers, and key chemical parameters on cement properties

Develop scientific methodologies and contribute to innovative research concepts

Publish research findings in peer-reviewed journals and present at scientific conferences

Collaborate with internal R&D experts and external academic partners

Prepare and submit your doctoral dissertation

Contribute to knowledge transfer between academia and industry
