Self-healing Conventional Concrete Using Bacteria
Concrete is most widely used as an epochal building material all over the world. However, the repercussions of its deterioration are inevitable ever since early stage of its service life. It is followed by the fixture and repair works, which is very labor intensive and also involve a lot of capital. This becomes uneconomic when the design period of the concrete is considered. Thus, many conventional surface treatments are applied, and also various alternative techniques are taken for the improvement of its mechanical properties. Self-healing of the affected concrete can not only be of great importance but also it uses the environment-friendly techniques. The present study pertains to the use of bacterial-induced self-fixing concrete which has a significant effect on its mechanical properties as well as crack healing capacity of conventional concrete. Two different species of genus Bacillus are incorporated to the concrete which repairs the crack by healing the microcracks occurred in the transition zone as well as enhance the mechanical properties of the concrete. Bacterial concentrations are varied and mixed with the concrete mix to observe the change in mechanical properties, and results show a remarkable increase in the strength of the bacterial concrete. Results indicated that bacteria showed an optimum result when mixed with the concrete in the concentration of 108 cfu/ml. The present work illustrated that the production of self-healing concrete by both the species has a capacity to improve the strength properties of conventional concrete.
