in the manufacture of a new type of concrete produces less carbon dioxide than when other types of materials

For many centuries the builders by mixing sand with different substances to make it as strong as possible. Unfortunately, scientists still have not managed to develop a composition that gives popular in the construction of houses material for maximum durability. Existing types of concrete, sooner or later collapse, however, scientists from the us state of Colorado have managed to solve the issue. In the composition they have developed concrete contains the so-called cyanobacteria, which are able to proliferate under the influence of the sun and oxygen. Yes, by using this technology is not stronger than concrete, but its easy to restore when damaged.

The properties Of "living" of concrete was described in the publication . According to foreign journalists, the new material is a mixture of sand, regularly fueling the composition of the liquid hydrogel and a bacteria of the genus Synechococcus. A gel-like mass provides the microbes necessary for growth substances and those with the development, produce calcium carbonate. This substance gives the material strength.

synechococcus (Synechococcus) mostly live in the aquatic environment

the Most durable concrete in the world

American scientists claim that they created the composition with bacteria under certain conditions are able to fully recover. For example, if the break created by new technology brick, it is possible to re-grow, dousing him with a mixture of hydrogel and sand. Under the influence of the sun and nutrients from the hydrogel, bacteria literally come to life and help the brick to regain the original shape. Importantly, around the damaged material was whole bricks, which will not allow the mixture to spread around the edges will help preserve shape.

The resulting material as hard as concrete. However, in too dry conditions, the bacteria can die and the bricks can lose the self-healing properties. At the moment, the researchers want to maximize the survivability of the microorganisms in the usual conditions. It is known that when the relative humidity is about 30% of the bacteria live for about a month, but the scientists intend to improve this figure.

But even now the achieved results are very interesting. The author of the scientific work of Chelsea Heveran and his colleagues broke the brick in half and by adding a hydrogel and sand were able to grow from one fragment eight absolutely the same bricks. They assured that the building material does not break, even if it is to advance. Although scientists are confident in the strength of the bricks, it seems that one of them is still very early to construct the building.

However, in the future, these bricks are very much in demand. One can build houses, and even dwellings . Moreover, the construction of such material will be easy to repair, besides it contains the bacteria can warn about increased concentration of harmful substances in the air. And all because they actively interact with the environment.

Generally, it is not only suitable for building houses of Martian material. Recently we wrote about the fact that for these purposes perfectly fit the so-called "mushroom" materials. Read more about them you can read in our .
