Abstract

The development of bacteria-based systems for the protection of concrete structures has gained lot of attention over the past few years as it could contribute to lower the maintenance cost and increase the durability of concrete structures. These systems are based on Microbial Induced Precipitation (MIP), a method by which calcium carbonate precipitation is induced by bacteria.

This paper gives an overview of field applications with the bacteria-based systems developed at the Delft University of Technology (the Netherlands): self-healing concrete and repair systems.

Field applications in collaboration with stakeholder parties involve casting of self-healing concrete as linings for irrigation canals in Ecuador (July 2014), patch repair for the waterproofing of leaking cracks with self-healing mortar (2013-2014) and improving the freeze-thaw resistance and sealing of cracks in parking decks with the application of a liquidbased repair system (2013-2016).

These large scale applications proofed the functionality and market potential of these bacteria-based protective systems.
