The innovation combines self-healing and CO₂-capturing concrete, addressing two critical issues in modern construction: the need for durable infrastructure and the urgent environmental challenge of reducing carbon emissions. By integrating bacteria that repair cracks in concrete with materials that capture CO₂ during the curing process, this technology not only enhances the concrete’s durability but also minimizes its environmental footprint. The bacterial strains
used are activated by moisture, which triggers their metabolic process, converting calcium lactate into calcium carbonate. This natural process effectively fills cracks in the concrete, significantly extending its lifespan and reducing the need for costly and resource-intensive repairs.
In addition to the self-healing properties, the concrete captures CO₂ from the atmosphere, particularly during its curing phase. This interaction is made possible by the specific formulation of the concrete, which includes unique materials designed to react with CO₂, forming solid carbonates and sequestering carbon within the structure. This dual-function concrete solves the problem of carbon emissions by acting as both a carbon sink and a highly durable building material. Unlike conventional concrete, which is a major contributor to global carbon emissions, this innovation offers a promising solution to reduce the carbon footprint of the construction industry.
