Self-Healing Concrete

Self-healing concrete is an innovative construction material that can repair its own cracks automatically without manual maintenance. It is developed by adding special healing agents such as bacteria or chemical capsules into the concrete mix. When cracks form and water or air enters, these agents get activated. In bacteria-based systems, the bacteria produce limestone (calcium carbonate) that fills and seals the cracks. In capsule-based systems, tiny capsules break open and release chemicals that bond the crack surfaces.
