Concrete in most structures is designed to crack in order to let embedded steel reinforcement take over
tensile stresses. Crack formation is also a typical phenomenon related to durability. Percolation of cracks may lead to
leakage problems or ingress of deleterious materials, causing deterioration of the concrete matrix or corrosion of
embedded steel reinforcement. Durability can be enhanced by preventing further ingress of water and other substances.
In recent years a bacteria-based self-healing concrete is being developed in order to extend the service life. A two
component healing agent is added to the concrete mixture. The agent consists of bacteria and an organic mineral
precursor compound. Self healing agents such as epoxy resins, bacteria, fiber are used to heal cracks in concrete.
Among these, bacteria used in concrete are effective. When the bacteria is mixed with concrete the calcium carbonate
precipitates forms and these precipitates filling the cracks and makes the crack free concrete. The state of art results in
all projects show that material designed as self healing agents.

We have kept IJCERT is a free peer-reviewed scientific journal to endorse conservation. We have not put up a paywall to readers, and we do not charge for publishing. But running a monthly journal costs is a lot. While we do have some associates, we still need support to keep the journal flourishing. If our readers help fund it, our future will be more secure.
