Passage
Modern infrastructure relies heavily on concrete, a material prone to developing microscopic cracks over time due to weathering and tension. Although these tiny fissures may seem harmless at first, they allow moisture and harmful chemicals to seep into the structure, which eventually corrodes the internal steel reinforcement. [1] Nevertheless, materials scientists have developed a self-healing concrete that utilizes bacteria to repair these cracks from the inside. The concrete is mixed with dormant bacterial spores and nutrients that remain inactive until a crack forms and water enters. Upon contact with moisture, the bacteria wake up and produce limestone, effectively sealing the gap before structural damage can occur.
