Self-Healing Concrete Is An Ingenious Solution To Cracked Roads
Ingeniously simple and inspired by nature, this “self-healing” concrete could mean cracked roads and potholes will soon become a thing of the past. Researchers at Binghamton University in New York have been working on a concrete that’s able to fill in its cracks using Trichoderma reesei, a fungus first isolated from a piece of cotton canvas in the Solomon Islands during World War II. Best of all, the solution is low cost and pollution-free. Their breakthrough was recently published in the academic journal .
“When cracking occurs, water and oxygen will find their way in. With enough water and oxygen, the dormant fungal spores will germinate, grow and precipitate calcium carbonate to heal the cracks.”
“When the cracks are completely filled and ultimately no more water or oxygen can enter inside, the fungi will again form spores. As the environmental conditions become favorable in later stages, the spores could be wakened again.”
The project still has a long way to go before it hits the market, as the researchers are still working on the survivability of the fungus in the rather unfavorable environment of concrete. Nevertheless, based on these promising results, the team are now confident that further investigations with other fungi or yeasts will reveal the key missing ingredient.
