Microstructural characterization of crack-healing enabled by bacteria-embedded polylactic acid (PLA) capsules

The current study investigates short-term and long-term crack-healing behaviour of mortars embedded with bacteria-based poly-lactic acid (PLA) capsules under both ideal and realistic environmental conditions. Two sets of specimens were prepared and subjected to different healing regimes, with the first set kept in a mist room for varying...

Development of autonomous-healing mortar using Geobacillus stearothermophilus

Autonomous healing by the microbially induced calcite precipitation (MICP) mechanism has garnered significant interest in the sustainable approach to concrete repair and maintenance. Previous research works have reported that Bacillus pasteurii and Bacillus sphaericus are the most commonly used in concrete associated with bacteria. However,...
