Abstract

Over the past few decades, the construction of buildings and infrastructure has required higher durability and performance in materials such as concrete. Concrete structures have high compressive strength and, with the presence of steel, are also flexible. The main weakness of concrete is its susceptibility to cracks caused by tensile, thermal, and environmental stresses. Although cracks in concrete may initially appear minor, they allow water, corrosive ions, and other environmental factors to penetrate, ultimately leading to reduced durability, which increases the cost of maintaining structures. A modern solution to this problem is the development of self-healing concrete. Self-healing concrete is a type of smart concrete that is capable of repairing cracks on its own without any human intervention. This concrete uses approaches such as the incorporation of bacteria, capsules containing a healing agent, or special cements to detect and repair the cracks that have formed. The advantages of this technology are contributing to sustainable development, greater durability, and reduced maintenance costs. This technology leads to increased environmental sustainability because reducing the need for maintenance and replacement of materials helps reduce the consumption of raw materials and the production of construction waste. In this study, using the science direct database and the keyword self-healing concrete, 60 articles published in the field of self-healing concrete up to 2025 were extracted and reviewed. In this section, the principles and mechanisms of self-healing concrete will first be examined. Then, the advantages, limitations and applications of this technology will be discussed.
