However, the highly alkaline environment inside the concrete, the continuous hydration of cement-based materials, and the mechanical extrusion and friction during mixing can cause the death of a large number of microorganisms, resulting in the repair effect failing to achieve the expected effect. Many scholars have selected microbial immobilization materials suitable for hydraulic concrete and immobilized coated bacterial liquid to improve the survival rate and long-term activity of mineralizing microorganisms in hydraulic concrete, ensure its mineralization and deposition performance, and thus better achieve self-repair of concrete cracks.
