摘要：

This scope study examines the progress in bacterial self -healing of concrete. 54 studies were reviewed, noting an increase in publications since 2015, with India leading the research. Various materials have been tested as substitutes in concrete, including fibers and recycled construction waste. The most commonly used bacteria are Bacillus subtillis and Bacillus sphaericus, which improve the resistance of concrete through the production of calcite and crack repair. The presence of fibers, ashes, and construction waste can help protect bacteria in an alkaline environment. This study highlights the importance of bacterial self -healing in concrete and provides an overview of advances in this research field.
