Abstract

Concrete is one of the most commonly used building materials, from building foundations to bridge constructions. Because the tensile strength of the concrete utilised is one-tenth that of the compressive strength, it cracks easily when stress is applied. Self-healing concrete is a material that may manufacture limestone organically to mend fractures that occur on the surface of concrete structures as a result of environmental factors. Bacillus bacteria are introduced to the concrete components, coupled with calcium lactate, a calcium-based nutrition, as well as nitrogen and phosphorus. In concrete, these self-healing compounds can remain dormant for up to 200 years. The addition of oxygen during the bacterial conversion of calcium lactate to limestone for crack repair is a plus. Oxygen is a vital ingredient that aids in the corrosion of steel and enhances the durability of steel reinforced concrete structures when bacterial activity has depleted the oxygen supply. Bacteria enhances tensile strength, water permeability, durability, and compressive strength of concrete. All concrete structures develop cracks of varying sizes, which must be manually filled, reducing the construction's lifespan. Self-healing concrete (SHC), on the other hand, is a revolutionary building material that solves all of these problems and is undoubtedly the material of the future.
