Jan Lindgård

Jan Lindgård is a Researcher at the Department of Structural Engineering, Norwegian University of Science and Technology (NTNU). His work focuses on alkali-aggregate reactions (AAR) and concrete durability, with particular emphasis on alkali-silica reactions (ASR) and pyrrhotite-induced degradation in concrete structures.

• Key Research Areas: Concrete durability, AAR/ASR mechanisms, accelerated testing methods, alkali leaching, microstructural analysis.
• Collaborations: Active in RILEM Technical Committee 258-AAA, SINTEF, international institutions.

His recent publications analyze pyrrhotite quantification in aggregates, ASR damage assessment in dams, and validation of CEN/RILEM testing standards. He investigates alkali release mechanisms and their impact on concrete performance through both field surveys and laboratory experiments.

Scientific activities include:

• Co-authoring multiple Academic Articles and Technical Reports
• Contributing to RILEM STAR Reports and Guidelines
• Participating in Norwegian Infrastructure Projects like COIN and PARTNER

Projects address ASR mitigation via low-alkali cements, silica fume additives, and field-lab correlation studies. His work informs Norwegian concrete standards and international AAR prevention strategies.
