Concrete will prolong to be the important material for building construction, but this concrete structure are subjected to cracking .These cracks on the surface of the concrete make whole structure obnoxious because of the water that ooze into the concrete. These cracks can be rehabilitated by self-healing concrete which will biologically produce limestone. There are two self-healing agent parts they are the bacterial spores and the calcium lactate. These agents are introduced to the concrete during the cement-mixing process. Therefore the bacteria that satisfy the above norms are Bacillus pasteurii and its optimum temperature is 35º- 45º. It is an environmentally, friendly, biotic process and it is also a self-remediating process. These self-healing concrete is potential of lengthening in service life of public buildings. The aim of our project is to develop a new type of concrete in which bacteria promote self-healing of cracks. Various tests such as compressive strength test, split tensile strength test and flexural strength test will be carried out. The grade of concrete used in our project is M20.
