What is it about?
Extruded cementitious hollow tubes were used for the first time to manufacture a self-healing concrete. The influence of the addition of the tubes on concrete workability, as well as on concrete mechanical properties was investigated. Finally, the repaired area, i.e. the area covered by the healing agent after samples damaging, was estimated.

Why is it important?
Our findings show that this solution is potentially able to repair damaged concretes and that the influence of the extruded cementitious hollow tubes addition on the mechanical properties of a concrete is limited.
Perspectives
Modelling of the behavior of the healing agent when it is released by the extruded tube will help us to improve the efficiency of this solution. We are working on this side now.
