Cracking the code: Deciphering how concrete can heal itself

Dr. Congrui Grace Jin has developed a groundbreaking self-healing concrete system inspired by lichen. This innovative approach uses a synthetic combination of cyanobacteria and fungi to autonomously repair cracks in concrete structures. The microbes work together, requiring only air, light, and water to produce crack-filling minerals. This technology could significantly reduce maintenance costs, extend infrastructure longevity, and improve safety in construction. The research has potential applications in sustainable building practices and even space infrastructure development.
