In Russia created concrete of incredible strength

August 23 2019 19

The new type of concrete was developed by specialists from the Far Eastern Federal University together with colleagues from Kazan State University of Architecture and Civil Engineering. The material is characterized by high strength, environmental friendliness and frost resistance, so it can be used for the construction of structures in the Far North.

The main difference between the new mixture and those used today in construction is increased early strength. According to the developers, this property will speed up the concreting process by 3-4 times. In addition, the new concrete does not require heat treatment during pouring, which makes it more environmentally friendly and can reduce the total energy consumption by 70%.

When creating a new type of concrete, scientists focused on natural stones, whose strength is many times greater than modern building mixtures. In the process of developing a promising material, the science of geonics was applied, the essence of which is the study of nature-like building materials.

Despite the fact that the mixture created by Russian specialists is several times stronger than ordinary concrete, work on improving its properties will continue. The goal of FEFU engineers is to achieve a material strength index comparable to that of mountain conglomerates or sandstones.

Well done, our Russian scientists! It is necessary that they necessarily manage to patent this invention.

When I see the highway without cracks, then I will believe, but for now it's a fairy tale.

  There is no destiny to see a highway without cracks anywhere ... in the climate of the Russian Federation ... Roads in Anchorage, Alaska are also in cracks, sometimes along the entire width of the strip ...

And not a word about the price. If the waste of the diamond industry is poured into concrete, then it will be the first time !!! (there were experiments)

    It's the same in Germany. Extreme weather conditions (it is cold in winter and very hot in summer) - and a truck for 60 tons is doing their vile business. The police are doing their job and pulling overloads from the roads. Control inspections of roads with timely fault detection are carried out automatically. Repair, both small and serious, is not postponed for a long time. Well, the technological standards are maintained, the materials are not watery. Such is the cycle of events.

What nonsense. What is diamond dust? Has a diamond file ever worked? How does this powder sprinkle from a bunch? Granite crumb of the corresponding fraction, and the CLASS Binder will work for hundreds of years. The main thing is the basis. If they throw it all in the snow in winter, and with a layer of 2 cm, then ... I watched how a track was built in backward India. A trench one and a half meters across the entire width and hundreds of kilometers in length. Down stone boulders. Next up is coarse gravel. Next is fine gravel. Roll away with heavy skating rinks. And on top is a bitumen - sand mixture. Typically, bitumen is boiled in barrels near the road. The mixture interferes with the hands, and in the basins, on the head they carry it where necessary. Rag turban on the head. So that the brains do not boil. Of clothes - a loincloth, a turban and Soviet soldiers' boots. Kearza. They walk on hot asphalt, a layer no less than a fashionable platform sticks to the soles. Spatula level, such as spatulas. And again the rink. Several layers of asphalt. All equipment - only this skating rink. And two meters above the terrain the road rises. That in the rainy period did not flood. The main thing is the foundation. There, if a swamp, then nothing will help.

Associated breed of kimberlite pipes.

A kimberlite pipe is an explosion propagation tube during a volcanic eruption. It has the form of a pipe-shaped channel with a diameter of 0,4-1 km, along which mainly on ancient platforms, there was a breakthrough of magmatic solutions and gases. Volcanic debris (breccias) cemented by solutions or a green-gray tuff-like rock of kimberlite, which consists of olivine, phlogopite, pyrope, carbonates and other minerals, and also has xenolith inclusions, are frozen in the explosion tube.

Basically, they are quite soft, with the exception of breccia, which is a mixture of pebbles and binding argelite-like (clay) rocks.
What durable material are we talking about?

  Excessive information, diamond dust will simply be included in the price, in certificates ... or in the eyes.
  
  Exploitation of roads involves not only timely repair. Limitations on the load must be respected, otherwise it makes no difference - asphalt, asphalt concrete or concrete - everything can be rolled to death.
  
  How much will a kilometer cover this road?
  Pilot project already rolled somewhere?
  ... or like Cheburashka -
  
  ... we built, built, and finally built.

- Another bullshit ...
- Today it is unclear from whose knowledge in Russia people were keen to build high-rise houses from ... from ... from ... crappy, trashy foam concrete ... - Several pillar bases are created around the perimeter of such a high-rise building (the whole house rests on them); and all the walls and, in fact, the whole house are blotted out of this foam concrete; then the house is covered with half-brick cladding from the outside and that’s all ... - this house is ready ... - Walls in apartments can be fingered with a fingernail ...; it’s impossible to hang anything on this wall, because all dowels with self-tapping screws simply fall out with pieces of this foam concrete ... - And the audibility is such that someone on the ground floor sneezes, then everything is audible on the twelfth ... - You can just talk to the neighbors through the wall (or quarrel) ...

  - With neighbors, you can just talk through the walls (or quarrel) - you can hear everything ... - You can hear how the TVs work, how strangers talk on their mobile phones and what they are talking about ... - you can also hear everything ... - I was recently with friends for a "housewarming" and was convinced of everything with my own eyes ... - it's just awful ...
  This is what bribes were given to those nonhuman people who approved and signed acts so that such houses, such a "horror" began to be built in Russia ...
  - Who invented this ??? The strength of the walls - no, "audibility" - even in a quiet, quiet whisper, so that no one can hear you (or better ... - leave the house to talk normally); the comfort of living is just disgusting ...
  - And then again everyone began to rant about that ... "oh, how strong this new concrete is !!!" And did anyone say at least a word about the sound permeability of walls made of this concrete ... - But people can live in buildings made of this concrete ... - and what it will be like for them to live there ... Or there will be "failed robots" , like the space "Fedor" ...

    Roads are concreted only in exceptional cases; build bridges from concrete (and even then - then asphalt); overlap etc ...
    And concrete roads are built only where special strength is required ... - runways at airports, at spaceports; carriageway for gigantic, huge payloads of tractor vehicles, dump trucks, etc ... - And to concrete millions of km of roads and ride on concrete is an expensive pleasure, and for cars it is quite costly and emergency ...
    - It is necessary to build houses from concrete, tunnels, various objects for various purposes, underwater structures, etc ... etc ...

I will draw an answer for you:

Try to draw all conclusions yourself.

The conclusions you have to do. The length of all roads in Germany does not exceed the length in the Moscow region. It follows that it is possible to make expensive roads over short distances to a very rich country. If you, in your Tmutarakansk, agree to wait a couple of hundred years until SUCH roads reach you, please wait. But, here 100 million Russians will disagree with you.

  No problem , lower salaries and raw material prices, as well as low-cost technology, makes roads cheaper and faster. Accordingly, they are being repaired faster, which in the conditions of climatically complex regions has certain advantages. There should be control on the part of both the customer and the state, but not at the familiar level. Well, everyone needs a conscience - from the manager to the worker.

      Judging by the length of the roads in proportion to the size of the country, I would say: build, build and build.
      And according to the rating, everything is not so bad at all, at least in the top ten.
      However, in some regions there are no roads, there are only directions.

That is ... In strength - worse than sandstone?
