Stefan Jacobsen

Stefan Jacobsen is a Professor at the Department of Structural Engineering, Norwegian University of Science and Technology (NTNU), specializing in concrete technology and durability. His research focuses on fresh concrete rheology, robotic production of sprayed concrete, porestructure-concrete property relations, and sustainability in construction. He holds a PhD (1995) and MSc (1986) from the Norwegian Institute of Technology. Previously, he worked in the concrete industry as a contractor and researcher, and spent a sabbatical at Princeton University (2012-2013). His work emphasizes competitiveness and environmental impact reduction through innovations in material composition and lifecycle analysis.

Education: MSc/PhD in Civil Engineering from Norwegian Institute of Technology (now NTNU), with thesis topics on abrasion resistance and freeze-thaw durability. Professional Experience includes roles at PEAB (Norway), Norwegian Building Research Institute, and Northern Research Institute. His recent research spans frost durability, alkali-silica reactivity, and phase change materials for urban infrastructure.

Key Research Interests: Concrete rheology, frost and salt scaling mechanisms, recycled concrete utilization, and environmental quantification. Techniques employed include X-ray tomography, digital image correlation, and advanced material testing. Collaborations include projects with Arctic and offshore engineering contexts.

Articles Trends: Recent work emphasizes durability under extreme conditions, material characterization via imaging, and sustainability through fly ash integration. Notable studies analyze air void systems, fiber-cement bonding, and robotic sprayed concrete anisotropy.

Awards and Grants: While no specific awards are listed, his extensive peer-reviewed output and industry collaborations reflect recognition in his field. Active in Nordic and international workshops on concrete durability.

Labs/Teams: Part of NTNU’s Concrete Group, contributing to projects like MiKS (Microproportioning with Crushed Sand). Research involves interdisciplinary teams focusing on material science and civil engineering challenges.
