Self-Healing of Concrete Using Bacterial Solution
Concrete being a versatile material is the most used material in construction, but its surface crack paves a path for the entry of moisture which leads to corrosion of the reinforcement leading to premature failure of structure. Innovative approach of using micro-organisms for the healing mechanism has shown adequate results in past. This research work is based on injecting a bacterial solution of bacillus megaterium into the cracked specimen which was cracked at 80% of the ultimate load and observing the repair capacity with the help of ultrasonic pulse velocity test. Some of the cracked specimens were dry-cured whereas others were wet cured after adding a bacterial solution. Also, in this study specimens with bacteria were cast, whose compressive and flexure strength was compared with conventional concrete, and self-healing was observed at intervals of 7, 14, 21, and 28 days. Results indicated that healing was faster in wet cured specimens than dry ones.
