Mechanisms of Bacterial Self-Healing Concrete Bio-concrete refers to concrete incorporating specific bacteria that enable the material to autonomously heal cracks. The concept, first pioneered by microbiologist Henk Jonkers in 2006, uses alkaliphilic spore-forming bacteria (e.g. Bacillus species) embedded in the mix alongside a nutrient or “precursor” compound. When a crack forms in the concrete and … Continue reading Bio-Concrete: Bacterial-Based Self-Healing Concrete in Sustainable Construction
