Concrete has long served us in many useful ways. It is a fantastic and lasting material, but everyone knows how quickly it can deteriorate after developing a crack. These cracks generally form with age and when it dries out more, eventually becoming a crumbling mess. Sadly this can even happen with high quality sprayed concrete.
Today, experts and creative minds are looking for ways to prevent, and possibly stop completely, the reoccurring problem of cracks. Researchers have found one of the solutions is to embed fungus in it so it can heal itself.
This innovative approach to how we make the material could solve many issues. They plan to embed Trichoderma reesei fungus into concrete during manufacturing. This particular fungus can stay inactive or dormant for years. When cracks start to form, this will allow air to reach the spores, consequently activating them.
As the spores start activating, the fungus will begin to spread. When this occurs they produce calcium carbonate as a by-product. Calcium carbonate is commonly known as limestone. It fills the cracks and halts any further degradation of the material. Although the material isn’t exactly concrete, it does the job that is required; hugely extending the lifespan.
However, the research into this is still in its early stages. Therefore, it shall be some time before we begin to see the introduction of fungus filled concrete on our streets. The long length of time prior to its introduction is due to extra research required for making sure the fungus is able to survive within it for prolonged periods.
One day, the possibility of concrete being able to repair itself may become a reality. Until then, companies like us will continuously aim to provide the current industry standard repair services, including on sprayed concrete. One of our main goals is to restore the country’s buildings and structures, so if you require our expertise, please contact us today.
