Determination of the Optimal Parameters for Self-Healing Efficiency of Encapsulated Bacteria in Concrete in a Simulated Subtropical Climate
| 项目名称： | Determination of the Optimal Parameters for Self-Healing Efficiency of Encapsulated Bacteria in Concrete in a Simulated Subtropical Climate |
| 摘要： | The main objective of this research study is to optimize self-healing mechanisms of encapsulated bacteria in concrete, and to evaluate whether a higher bacteria cell concentration, better nutrient selection, or an alternative encapsulation method is needed. These parameters will be first tested in mortar beams with respect to self-healing efficiency, and depending on the results, further testing will be carried out in concrete specimens. The efficiency of the proposed bio-concrete will be tested to evaluate the bacteria’s effect on concrete’s intrinsic properties such as compressive strength and static modulus of elasticity, and monitor the self-healing efficiency through crack repair throughout 28 wet-dry cycles (consisting of 8-hours of water immersion and 16-hours of drying). If successful, this project will move to implementation through field-testing in Region 6, where it will help to preserve and enhance the performance of the concrete transportation infrastructure. |
