Abstract

Cracks in reinforced concrete structures exposed to chlorides can impair significantly the durability. Local depassivation of the reinforcement in the crack is more likely due to the missing alkaline environment and/or due to the penetration of aggressive agents such as chlorides. Therefore, relevant standards require additional measures to prevent fast chloride ingress with regard to endangered, cracked structures. One innovate option to treat cracked concrete is the application of a crack filler material with self-healing properties. Such a material is a liquid repair system to be applied on cracked concrete surfaces and in which active bacteria produce limestone that reduces the permeability of cracks. The objective of the presented paper is on the one hand to develop a reproducible, practical corrosion test method to assess the self-healing filler material and on the other hand to show first results on the corrosion behaviour of the reinforcement through application of selfhealing filler material in cracked concrete.
