Schlangen, E. Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2012-12-31 Abstract Many researchers proposed self healing mechanism using hollow fibres and or microcapsule containing a modifying agent dispersed in the concrete to prolong its service life and make it more durable. A novel self healing concrete concept is proposed in this paper by using porous network concrete components. They are placed at the surface or internally in the concrete structure. The porous network is considered as media to transport healing agent to a crack or cracks in the concrete structures. In order to test the concepts, we designed two concrete specimens. The proposed self healing mechanism was tested by applying a uniaxial direct tension load in a cylinder and a three points bending load for a beam. After the crack was formed, manual injection through the porous network was carried out until healing agent reached the fracture surface. Experimental results showed that the crack was healed and mechanical recovery took place.
