Selection of Nutrient Used in Biogenic Healing Agent for Cementitious Materials

Biogenic self-healing cementitious materials target on the closure of micro-cracks with precipitated inorganic minerals originating from bacterial metabolic activity. Dormant bacterial spores and organic mineral compounds often constitute a biogenic healing agent. The current paper focuses on the investigation of the most appropriate organic...

Preparation and optimization of bio-based and light weight aggregate-based healing agent for application in concrete

The innovative technology of self-healing concrete allows the material to repair the open micro-cracks that can endanger the structure’s durability, due to ingress of aggressive liquids. Various concepts of self-healing concrete use encapsulation techniques, in order to immobilize and protect the healing agent during mixing and setting. In this...
