It is almost impossible to avoid the development of cracks on the surface of the concrete even after using the best quality material and workmanship. These cracks may result into the degradation of concrete in terms of its strength and durability. Therefore it becomes utmost important to seal these cracks so that the devastating effects of the degrading agencies that may enter into the concrete through these cracks can be reduced or eliminated. This paper presents a review on the effects of the concentration of various bacillus family bacteria on the strength and durability properties of concrete. The bacteria with a concentration of 10 0 CFU to 10 8 has been considered in this review. This paper also outlines the self-healing ability of different bacillus family bacteria. Self-healing refers to the cracks in concrete, through addition of the bacillus family bacteria to the concrete mix and checks the impacts of bacillus family bacteria on the strength and durability properties of the concrete.
