Self-Healing Mechanism of a Concrete Using Chemical Agent

Abstract | The formation of fissures in cement-based materials and concrete, resulting from both self-induced processes and external forces, presents a major obstacle to the sustained durability and structural integrity of buildings. To address this issue, scientists have created a groundbreaking technique with built-in abilities for self-sufficient crack repair, referred to as self-healing concrete, which holds great potential for improving the lifespan of structures and minimizing environmental harm. This approach provides both a self-regenerating repair mechanism and the possibility for independent restoration, substantially lowering maintenance requirements and simultaneously increasing the lifespan of concrete constructions. This article thoroughly examines the operational principles, manufacturing methods, and self-healing properties particularly in terms of crack restoration and mechanical function—of concrete integrated with chemical-based self-repairing agents. These substances include various materials such as sodium silicate, calcium nitrate, dicyclopentadiene, calcium hydroxide, calcium sulfoaluminate, silica, and superabsorbent polymers. This review considers both self-induced and independent self-healing methods, with literature indicating that cracks can be effectively repaired and mechanical properties can be substantially recovered. The effectiveness of healing and the restoration of mechanical properties can vary considerably depending on the type and concentration of the healing agents. Numerous studies have reported over full restoration of mechanical strength and complete healing of crack depths. Superabsorbent polymers serve as highly efficient self-repair agents, especially when used in conjunction with self-healing agents such as calcium nitrate or CSA. Chemical-based self-repair agents offer an effective method for improving concrete durability, ensuring structural safety, and facilitating their real-world use. |
