BACTAHEAL- PR
(Proven Enzyme, Bacterial formulation for Self healing concrete)
INTRODUCTION:
Prions Biotech offers enzyme blend BACTAHEAL-PR. The BACTAHEAL-PR is a new concept in the
cement industry. Cracks in concrete are a common phenomenon due to the relatively low tensile strength.
Durability of concrete is impaired by these cracks since they provide an easy path for the transportation of
liquids and gasses that potentially contain harmful substances. If micro-cracks grow and reach the
reinforcement, not only the concrete itself may be attacked, but also the reinforcement will be corroded.
Therefore, it is important to control the crack width and to heal the cracks as soon as possible. Since the
costs involved for maintenance and repair of concrete structures are usually high, this research focuses on
the development of self-healing concrete. Self-healing of cracks in concrete would contribute to a longer
service life of concrete structures and would make the material not only more durable but also more
sustainable.
Crack occurrence in reinforced concrete should be minimized for both durability and economical reasons
as crack repair is costly. Autogenous repair, or self-healing, of concrete would save a substantial amount
of money, as manual inspection and crack repair could be minimized. Thus, a reliable self-healing
mechanism for concrete would not only result in more durable structures, but would also be beneficial for
the global economy. This study exploited the potential to apply calcite-precipitating bacteria as a crackhealing agent in concrete.
The potential of different species to precipitate calcite, produce endospores, survive concrete-production,
and heal cracks by sealing them with calcite was investigated. Furthermore, the mechanical properties of
‘bacterial concrete’ were tested. ESEM studies showed that alkali-resistant spore-forming bacteria
