Erik Schlangen

Chair of Experimental Micromechanics
Delft University of Technology

Civil engineering structures are designed to have a long service life. During the life time of the structure some level of degradation of the used materials will always take place leading to damage in the structure. In this presentation self-healing concepts for civil engineering materials will be introduced. Various ways of implementing self-healing for concrete and asphalt will be explained. Furthermore the benefits for durability, sustainability and economics of our infrastructures will be discussed and illustrated with real examples.   Dr. Erik Schlangen is Professor in the chair of “Experimental Micromechanics” at the faculty of Civil Engineering and Geosciences at Delft University of Technology in the Netherlands. He is also the director of the Microlab for micromechanical and material research which is part of the same University. Prior to joining Delft University he was a senior materials engineer at the materials research institute Intron in the Netherlands. He has a MSc-degree in Structural Engineering from Eindhoven University of Technology and a PhD from Delft University, where he graduated in 1993. He is specialized in fracture mechanics of quasi-brittle materials like concrete, durability mechanics, finite element modelling, design of experimental techniques and self-healing of concrete and asphalt. He is the inventor of the Delft lattice model for simulation of fracture. He owns a patent on healable concrete. He initiated the self-healing bacterial concrete and is the inventor of the self-healing asphalt with steel-wool and induction heating that is applied in several applications. He is very active in RILEM committees and is chairman of the Technical Committee dealing with self-healing phenomena of cement-based materials.
