N2 - Changing from damage prevention to damage management, thereby allowing some cracks in a structure as long as the cracks self-repair over time, is the basic concept behind self-healing materials. Following nature, where wood fibers allow for both transport and bonding possibilities, this paper describes various options to apply wood fibers. Preliminary results on how to obtain single wood fibers and initial experiments on concrete crack width are presented. It is shown that the boundary conditions for a successful application of wood fibers as self-healing carriers can be met. However, it is also shown that many very practical obstacles in the manufacturing of self healing concrete still need to be cleared.
