Biogenic self-healing mortar: Material development and experimental evaluation

In concrete structures, it is always a preferable idea to prevent the damage before it happens rather than to repair it afterwards, since it is usually less costly and in some cases the damage detection is impossible. Temperature and humidity fluctuations and/or external loading can trigger micro-cracking on a concrete structure, which in turn...

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...
