Abstract
Bacterial concrete is an innovative material designed to enhance the durability and longevity of concrete structures. By incorporating calcite-precipitating bacteria, this self-healing concrete can autonomously repair cracks, preventing structural deterioration. This paper explores the concept, mechanism, benefits, and challenges of bacterial concrete, highlighting its potential as a sustainable construction material. The significance of this research lies in its potential to revolutionize concrete durability and sustainability. Bacterial concrete offers a self-healing mechanism that reduces maintenance costs, enhances structural longevity, and minimizes environmental impact. By exploring bio-mineralization techniques, this study contributes to advancing eco-friendly, cost-effective, and innovative solutions for sustainable construction practices. Alternative: Natural Self-Healing, Mineral Admixtures, ChemicalBased Self-Healing, Bacteria, Based Self-Healing. Evaluation Preference: Ease of Availability, Performance, Cost, Performance Time. The results show that Natural Self-Healing has the highest ranking and Mineral Admixtures has the lowest ranking. Natural Self-Healing has the highest value for Bacterial Concrete according to the ARAS approach.
