I! Pretending to Be Reborn, Director of Doomsday Hoax

No one knows if this is possible,

And, how much will it cost, and how many months of experimentation will be required!

most of the time,

The frontier of science is constant trial and error.

Let alone one of a hundred projects succeed,

Among the [-] projects, there is a very optimistic probability that one of them can successfully come out and enter a new field that humans have never reached.

"Professor Campbell, Professor Ain and Commander-in-Chief please!"

An assistant's voice came from outside.

Campbell pushed aside the documents on the table and stood up.

The Secret Service and the leader are looking for him, probably because of the giant wall of wind and snow.

The main material of the Berry Country Fortress and the Wind and Snow Wall is concrete.

And Campbell, as the country of Berry, is also the top person in the world in the development of structural concrete, so he naturally took over this task.In Berry Country, he still has a nickname.

"'II Father of the Snowstorm Wall"

—Hours later, Berry Country Capitol.

"Berry Country Fortress, Wind and Snow Giant Wall Construction Problems"

Very simple and clear parliament theme.

This is a big country project related to the survival of the country and the survival of the people of the country.

No matter how beautiful the plan is and how comprehensive the considerations are, once it is implemented, there will still be a lot of thorny problems!

And this time the topic is to solve some key dilemmas related to the foundation of the giant wall of wind and snow!

Ain is the director of the Secret Service, and also the commander in chief of Berry Country's response to this doomsday.

He made a simple opening statement, saying:

"Currently, besides ordinary concrete, the main material of Berry Country's Snowstorm Wall is several new and special types of concrete.

"First, it is electromagnetic barrier concrete. This is a concrete that can prevent the influence of high-frequency electromagnetic fields, thereby effectively controlling the radiation propagation of electromagnetic waves from one area to another.

"This kind of concrete is mainly used in some special military areas, and it is also used to reduce electromagnetic radiation pollution!"

This is actually quite necessary.

After Berry Country was closed by the giant wall of wind and snow, the interior was completely isolated from the atmosphere of Blue Star.

A large amount of electromagnetic radiation, if not shielded and absorbed, may have a negative impact on the people inside.

Unstable telecommunications video and communication quality is still a trivial matter, but physical health is a big problem!

"Also, there is air-purifying concrete!"

Having said that, Ain cast his eyes on Campbell.

The latter nodded slightly in response.

Air-purifying concrete was developed by Campbell.

He added photocatalysts such as nano-titanium dioxide to mortar and concrete to make photocatalytic concrete, which can decompose and remove carbon dioxide, nitrogen oxides and other harmful pollutant gases in the air.In addition, it can also perform air evolution capabilities such as physical adsorption, chemical adsorption, ion exchange, and rare earth activation.

This is also the biggest reason why Berry Country dared to build a giant wall of wind and snow to surround the whole Berry Country and isolate it from the outside world!

Without cutting-edge materials and high-tech technology, a complete physical blockade is courting death!

Ain went on to say: "Of course, there is also temperature self-monitoring concrete. It can measure the temperature changes inside the wind and snow giant wall and on the surface in real time.

"Moreover, temperature self-regulating concrete also has a huge prospect. It may be possible to use the outdoor temperature difference to provide electricity to buildings through the thermoelectric effect of cement-based composite materials!"

Hearing this, Campbell, who had been silent, frowned.

He stood up, this stubborn old man did not allow anyone to misunderstand the concrete he developed, and said, "Professor Ain, this is wrong."

"Huh?" Ain looked over, with a sullen expression on his face.

Right-degree self-monitoring concrete: It is indeed beneficial to avoid the temperature difference between indoor and outdoor, and the possibility of providing electric energy. However, the basis of all this is solar energy! "

"Is there another saying?"

"Yes, solar energy and the temperature difference between indoors and outdoors exist at the same time to provide electricity to buildings!"

Ain thought for a while, then asked: "That is to say, solar energy and indoor and outdoor temperature are all conditions that must exist?"

"It's a white spoon."

"Is it possible, to convert solar energy into wind energy?"

At this moment, Campbell was silent, and asked: "You mean to use wind energy and the temperature difference between indoor and outdoor to generate electricity? It's unlikely. Wind energy and solar energy are two forms of energy, and there is no similarity at all."

"But it's all energy, isn't it?"

Ain smiled, and said, "It doesn't have to be wind energy. After using the 'Berry Country Kite' to utilize wind energy, and then transfer it to this temperature self-regulating concrete, can energy be transformed?"

When this idea came out, Campbell, who had been showing doubts, was suddenly shaken!

The power generation efficiency of the Berry Country Kites is actually not high.

But if the Berry Country kite is used as an auxiliary temperature self-regulating concrete, the giant wall of wind and snow covering the entire Berry Country becomes a tool for power generation...

The electricity generated will be extremely terrifying!

"I can't guarantee it! But...Professor Ain, your proposal is very novel!"

Campbell sat down, pondering the feasibility of such a plan in his mind.

Ain, on the other hand, continued to introduce various new types of concrete made by Berry Country.

After more than ten minutes, Ain raised the four problems facing the giant wall of wind and snow.

He looked at Campbell, the top concrete science master in Berry Country, the father of the Great Wall of Wind and Snow, and said:

"Professor Campbell, in the process of building the fortress in the Great Berry Country, four problems have become increasingly serious.

"First, we don't have concrete that can be produced and mixed normally at low temperatures, and the problem that this brings is that during the next Little Ice Age and winter, the construction will be greatly affected, and the construction progress will even be stagnated!

This will make the already scarce time even more scarce!

"Second, instead, you chose self-diagnosing, self-healing (of Li's) smart concrete, and as far as I know, the current research progress has been suspended, and it seems to have encountered an insurmountable problem.

The interruption of the progress of smart concrete will affect the construction progress of the giant wall of wind and snow.

"Third, the giant wall of wind and snow is too high and too thick, and the gravity and load force it brings are extremely terrifying. How can we ensure that the concrete below is not cracked?"

"The fourth problem is also the most urgent problem currently restricting the construction of the wind and snow giant wall... How to pour concrete at high altitude without losing quality?"

The first question refers directly to the construction period.

The second question is about the most important special concrete today.

The third and fourth questions are aimed at the specific construction of the giant wall of wind and snow.

This is still a very prominent and huge dilemma that has to be solved. In the actual construction process, there are still many small problems that need to be overcome.

At this moment, everyone also felt that the difficulty of building this giant wall of wind and snow, which seemed to have the least technical content, was extraordinarily great!Ain, Yoder and the others were horrified.

Even the huge wind and snow wall with a simple structure and basically no complicated construction has huge technical problems. How did the super dungeon in the Dragon Kingdom be built! Xu Qiu...one person can solve all the engineering problems. Solve it?

After a long silence, Campbell stood up worriedly.

In his hand, he holds the data and parameters of the construction of the giant wind and snow wall in the whole country, and in his head is the world's most cutting-edge concrete science and technology. Only he can answer these questions.

"First, the first question."

Campbell's voice was a little hoarse, and he maintained a contemplative posture, and said:

"I'm afraid there is no good solution to the problem of construction period.

As long as the essence of concrete does not change, it will be difficult to mix, mix and use it under severe cold. This is a worldwide unsolvable problem!

I believe that even the Dragon Kingdom may have to shorten the construction period due to the Little Ice Age and the cold winter.

In this regard, countries in the equatorial region have a natural advantage. As long as there is no accident, their winter is still above zero degrees Celsius, and they have a longer construction time than ours! " Ain was a little surprised, and said: "The Dragon Kingdom can't produce concrete that can be used in severe cold? "

"I think so. It's impossible!" Campbell said firmly.

"So, what about the second question?"

Campbell replied: "The development of self-diagnosing, self-healing smart concrete has indeed stalled.

"Our idea is to embed shape memory alloy SMA wires and liquid core optical fibers in concrete to form a densely distributed self-diagnosing and self-repairing network in concrete.

"Theoretically, the light emitted by the laser tube enters the liquid core fiber through the coupler, and the outgoing light of the fiber is received by the photosensitive tube.

Through the data acquisition and processing system, the position, type and degree of the internal damage of the concrete are displayed,

And drive the control circuit to work, excite the local SMA wire, generate local compressive stress, break the liquid core optical fiber at the damage, and the glue will flow out.

The damage can be repaired by itself.

"And, if cracking, delamination, degumming and other damages occur in the concrete structure, the SMA wire at the damage site will generate compressive stress,

You can restore the structure to its original shape!

"However, in the actual manufacturing process, self-sensing and self-regulation have basically been achieved, and self-repairing has always been unsatisfactory and has encountered barriers."

Ain didn't like to hear this nonsense, so he asked directly: "How much budget is needed, and how long is the development cycle?"

A hint of self-mockery appeared at the corner of Campbell's mouth, and he said, "Professor Ain, you are also engaged in scientific research, and you understand what barriers mean!

"If you are lucky, the direction is right, zero budget, it can be solved in an instant!

"However, if you are unlucky, even if it takes hundreds of years to evacuate the treasury of the Berry Country, it will be a waste of work!

"I can't guarantee the budget, but we have encountered difficulties in the development of our multifunctional smart concrete. We may have to stop the research and use concrete that only has self-sensing and self-regulating capabilities!" Ain felt cold, but But there was nothing he could do. He sighed and said, "It's okay to be able to self-regulate. At least, there is a possibility of using wind energy and outdoor temperature difference to generate electricity in the later stage."

He went on to ask:

"Next, how to prevent the concrete at the bottom of the giant wall from being cracked, and how to ensure the quality of concrete pouring at the height of the giant wall in the wind and snow?".
