Self Healing Concrete an overview ScienceDirect Topics

The self-healing flakey additives developed by Jonkers and Mors (2012) were also tested in outdoor conditions, by adding them to a commercially available repair mortar. A 8 m 2 degraded concrete wall was pretreated by removing the degraded layer up to or until behind the reinforcement. The healing agent containing mortar was applied by spraying. Observations were made regarding practicality

Self-healing Concrete : GCCA

Self-healing Concrete. Concrete’s ability to heal reduces the need to detect and repair cracks that may otherwise lead to corrosion of reinforcement and deterioration of the concrete. This reduces costs, while boosting durability. Many concrete elements crack without there being any concern; some are even designed to crack.

Self Healing in Concrete Materials SpringerLink

The phenomenon of self healing in concrete has been known for many years. It has been observed that some cracks in old concrete structures are lined with white crystalline material suggesting the ability of concrete to self-seal the cracks with chemical products by itself, perhaps with the aid of rainwater and carbon dioxide in air.
