Abstract This paper presents the experimental results of self-healing efficiency of two different bacteria namely Bacillus sphaericus and Bacillus subtilis incorporated in with polypropylene fibre reinforced concrete. Concrete was prepared with an optimum amount of polypropylene fibre and cultured bacteria. The artificial cracks were formed in the concrete to perform this investigation. The cracked concrete was observed at constant intervals. The effectiveness of self-healing was evaluated by the mechanical test over the bacterial concrete with fibre (BCF). The results obtained from the mechanical study show that the BCF produced commendable results. The precipitation characteristic analysis was carried out by SEM and XRD diffractogram analysis was performed to confirm the precipitation in BCF. The analysis shows that there is a presence of sufficient self-healing compound in cracked concrete. The effectiveness of the developed BCF concrete in regaining strength shows a substantial increase in strength after self-healing therefore, the effectiveness of self-healing of BCF is admirable.
