Unlocking the potential of bacterial self-healing in concrete: applications, and challenges for sustainable infrastructure

Bacterial Self-Healing Concrete: Mechanisms, Incorporation Methods, and Future Perspectives — A Comprehensive Review

Bio-concrete or self-healing concrete is an innovative concept concerning sustainable construction materials. Contrary to regular concrete prone to progressive deterioration due to the formation of cracks, specific types of alkali-tolerant bacteria, primarily Bacillus, make it possible for bio-concrete to produce CaCO₃...

Preparation of Magnetic Microbial Repair Material and Its Application in Concrete Crack Healing

Due to its high brittleness and low tensile strength, concrete is vulnerable to cracks, which will compromise the safety and service life of a structure. Although microbial repair materials have gained attention for their compatibility with concretes and their eco-friendly nature, they have limitations, such as a res...
