Concrete has played a vital role in the construction industry since 19th century with the development of industrially produced Portland cement. In today’s world we are surrounded by concrete due to its unique properties such as high compressive strength, fire resistance, easy to cast etc., making it highly beneficial for massive construction projects. But, regardless of the fact how well the concrete is mixed or reinforced, it still develops cracks over time due various factors such as low tensile strength, temperature change, freezing-thawing etc. From the=is study, it is quite evident that using bacterial concrete (having bacterium in cement matrix and using recycled aggregates immersed in bacterium culture) will not only increase the strength parameter and self-heal the structure but also reduce the construction waste produced.
