Concrete is a very resilient and versatile construction material. Although Concrete can be spoiled by many channels, such as the spreading of corrosion from reinforcement bars, freeze-thaw conditions of trapped water, sun rays, fire, sea water effect, leaching, erosion by fast-gushing water, physical damage and chemical damage (from chlorides, sulfates etc.). Construction impediments and mix design intricacies using natural waste materials is the reasonable evidence for a need for another type of concrete. Scientists enthused by nature have formulated self-healing concrete which is able to repair itself as a consequence of the metabolic activity of bacteria. One noteworthy area of curiosity is bacterial concrete. In the past decade, a lot of researchers have put their effort into this field. It has transpired as a promising advancement to extend the service life of infrastructure in the construction field. In this review, the basic concept of bio-concrete along with research works performed is mentioned. Evaluation of self-healing performance and application of bio-concrete in fieldwork is illustrated.
