What is bio-concrete

What is bio-concrete

Bio-concrete, also known as biogenic concrete, is a new and innovative type of concrete that is designed to be self-healing and more environmentally friendly than traditional concrete. It incorporates the use of living organisms, such as bacteria or fungi, to repair cracks and damage that may occur over time.

The idea of bio-concrete originated in the Netherlands in 2015 by microbiologist Hendrik Jonkers. He and his team at Delft University of Technology developed a sustainable and biodegradable concrete that has the ability to produce its own healing agent.

The concept behind bio-concrete is that when a crack forms in the concrete, water and oxygen seeps through the crack and activates the bacteria within the concrete. These bacteria then produce calcium carbonate, which acts like a glue and fills the crack, sealing it and restoring the integrity of the concrete.

The living organisms used in bio-concrete can survive for up to 200 years, making it a long-lasting and durable solution for concrete structures. This makes it an ideal choice for infrastructure such as bridges, roads, and buildings, which are constantly exposed to wear and tear.
