Investigating and Learning More about Self Healing Concrete

Concrete is a widely accessible and inexpensive building material. Therefore, improvement in concrete aims to increase its compressive strength and structural longevity by the use of microorganisms harbouring MICP. The goal of the current work is to use a microbiologically induced unique growth to improve the performance of concrete. One of these has resulted to the creation of a highly specific type of concrete known as self-healing concrete, which uses bacteria to repair flaws in the mortar and concrete. Researchers using various microbes suggested various concretes. Using the bacteria "Bacillus subtilius," an attempt was made in this instance. According to this investigation, the presence of bacteria significantly increased the compressive strength. In this research we add 10ml, 20ml, and 30ml bacteria in concrete and check its compressive strength at 7days, 14days & 28days. We observed that 30ml Bacteria added in concrete gives maximum compressive strength in concrete.
