Effect of Self-healing Concrete on Modular Structure

摘要: 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 …
