Fractures in concrete structures, if not promptly treated, tend to spread, leading to expensive repairs. Despite modern technology's ability to reduce cracking severity, repairing concrete cracks has long been a research focus. Cracks and fractures are common in buildings, paved surfaces, and historical monuments. We've developed an innovative method for crack sealing using a continuously self-improving and environmentally beneficial biological process. Our investigation induced CaCO3 using Bacillus Sphaericus, a common soil bacterium, emphasizing the importance of understanding microbial involvement in crack restoration. To extend service life, we've recently created microorganisms based self-relieve concrete, consisting of a two-component relieve agent with microorganisms and a mineral precursor chemical. When cracks and water are present, active microorganisms transform absorbed organic chemicals into calcium(Ca) precipitates, effectively sealing and blocking cracks for self-relieve.
