Abstract

The concept of self-healing concrete has gained significant attention as a sustainable solution to the common problem of microcracks that compromise the durability and longevity of concrete structures. Among various self-healing techniques, the use of bio-inspired methods, particularly algae-based healing agents, offers a promising alternative due to their eco-friendly nature and efficiency in crack repair. Algae, especially microalgae, produce biopolymers that promote calcium carbonate precipitation, filling cracks and enhancing concrete durability. This approach leverages the natural process of biomineralization, where algae facilitate carbonate formation, effectively sealing cracks and reducing water permeability. Recent studies have demonstrated that algae-based healing agents not only expedite the crack healing process but also improve the mechanical properties of concrete, including compressive strength and resistance to aggressive environments. Additionally, algae are abundant, renewable, and can thrive in harsh conditions, making them a cost-effective and sustainable choice for concrete repair. This paper explores the mechanisms by which algae-based systems induce self-healing, reviews experimental findings, and compares the performance of algae-based self-healing concrete with conventional methods. The study highlights key factors such as optimal conditions for algae growth, nutrient availability, and integration of algae within concrete mixtures. By addressing both the challenges and potential of this technology, the study aims to pave the way for wider adoption of algae-based self-healing concrete as a resilient and environmentally friendly construction material.
