Innovative concrete with ‘sleeping’ bacteria can repair cracks on its own

The secret ingredient of innovative concrete is special polymer fibers biofiber It has a dual function of increasing strength and self-healing ability.

This could solve a major problem

Traditional concrete structures often require constant maintenance due to the adverse effects of weather conditions, which leads to the appearance of cracks and corrosion. Biofibrobeton aims to solve these problems by introducing biofibers containing “sleeping bacteria” that are activated when cracks appear.

Just add water

The BioFiber manufacturing process involves the integration of polymer fibers into concrete coated with a hydrogel layer containing immobile bacteria known as endospores. These fibers, covered with a protective polymer sheath, activates the presence of moisture.

The self-healing mechanism of biofibro concrete becomes evident when cracks appear. When water penetrates the concrete, the hydrogel expands and moves towards the surface. waking up dormant bacteria. These bacteria then consume carbon and calcium from the surrounding concrete, producing calcium carbonate, a cementing substance that effectively fills the crack.

Human skin helped

The design of BioFiber concrete was inspired by nature, specifically the regenerative abilities of human skin. By mimicking this natural process and using calcium carbonate-forming bacteria, developers aim to create damage-resistant, self-healing concrete.

The introduction of biofiber-based concrete is expected to contribute to reducing CO emissions as well as simplifying building maintenance requirements.₂ in concrete production. Developers believe that this environmentally friendly and efficient building material can revolutionize the industry by providing a sustainable solution to ensure the longevity of infrastructure.
