Created "living" concrete, able to "heal" itself

Scientists from the University of Colorado have createda unique invention that can help buildings of the future self-repair after any mechanical or natural damage. In addition, “living concrete”, teeming with photosynthetic bacteria, can largely behave like a living organism, according to the news portal sciencealert.com. Can a new development appear in mass marketing? Let's try to reason about this in this article.

A new type of material can turn our ideas about the technology of building buildings of the future

Self-healing material in case of damage

Creating material capable ofself-healing in the event of any damage, for a long time remained a dream for builders and architects who want to at the same time simplify and reduce the cost of the process of building buildings. The mixture obtained as a result of experiments by scientists from the USA can radically change the process of erecting complex structures due to the presence of sand, gelatin and cyanobacteria capable of photosynthesis.

By the way, you can find even more useful news from various fields of modern science in our channels in Telegram and Yandex.Zen.

During a verification experiment withthe resulting structure, scientists cut the unique substance into pieces, suggesting its further growth and regeneration. When the experiment was successful, the researchers came to the conclusion that the self-assembly of the same damaged material worked on average three times, after which the cyanobacteria necessary for the restoration of the substance died, while changing the color of the material. So, initially the green shade of concrete was gradually painted in plain gray, however, under the right conditions, it gradually returned to its original characteristics.

For the first time about the unique properties of “living concrete”was mentioned in 2019 when The New York Times published a new building technology based on a specially designed hydrogel. The unique development provides comfortable living conditions for microorganisms inside the substance, which, in turn, produce calcium carbonate necessary for the strength of the future material.

The unique properties of the new type of concrete allow it to regenerate without human intervention.

Researchers Conducting Experiments oncreating the concrete of the future, we are sure that their development can contribute to the development of technologies necessary for the construction of buildings on the moon and Mars during the beginning of human colonization. The relatively low cost of technology and significantly lower weight of a useful substance can drastically reduce the amount of materials needed to build future colonies of mankind on other planets of the solar system and their satellites.
