Before Li Wenjun himself was reborn, he could only learn English and electronic technology in a factory dormitory, and he still learned it.
Li Wenyong thought for a while: "Okay. Thank you for your hard work, please help me take care of him more."
People participating in the aviation show come from all walks of life.
Learning to deal with all kinds of people is a great thing.
Li Wenyong added: "As for the high-strength cement, we achieved the 475 mark a while ago, which is cement with a tensile and compressive strength of 475 kilograms per square centimeter."
Li Wenjun said: "It's not enough yet, it's best to make the number more than 700."
Li Wenyong frowned: "What on earth do you want such high-grade cement for? To build a space shuttle?! Ordinary construction bridges only need C40 concrete. Isn't C40 concrete the same as 425-grade cement?"
Li Wenjun said: "The concrete I want can not only block bullets, but also block ground-penetrating missiles."
Li Wenyong: "How many tons of bombs were dropped from the plane?"
Li Wenjun said: "Yes."
Li Wenyong shook his head: "Impossible. Don't even think about it. If you throw it down from such a height, its weight will break through the floor. Not to mention it will explode."
Li Wenjun said: "Yes. Moreover, the tip in front of the bomb will have enhanced cone protection, so the bomb can still drill and fall when it hits an obstacle at high speed. It will drill down dozens of meters before exploding, which is better than ordinary bombs when it hits an obstacle." The power of the bomb is even more terrifying, and it is specially designed to attack multi-story buildings and basements."
Li Wenyong felt chills all over his body: "Is there such a missile?"
Li Wenjun said: "Yes, the United States made the Goblet missile in 1940. The United States' joint-guided missile can penetrate a twenty-story building and penetrate into a basement with a thickness of up to 60 meters. In fact, Yang Shouzhuo and the others are also developing it. But this kind of thing is a 'spear' and a 'shield'. If you know that others have such bombs, you must find a way to make concrete that can withstand such bombs."
Weapon research and development is relatively sensitive, so he did not ask Yang Shouzhuo about this.
The reason why he knew this was because the weapons research and development trends of various countries had always been similar, so he could guess it.
Li Wenyong pursed his lips and remained silent.
He wanted to say that Li Wenjun was whimsical.
But nothing seems impossible in this world.
In the past, they also thought that trains could not be that fast, that it was impossible to make phone calls without a wired connection, and that a plane that could fly without a human driver was a fantasy.
Now these are all implemented here in the same way.
Li Wenjun said: "In fact, several universities and research institutes in China are already doing research. In addition to using high-grade cement, there are many ways to improve the strength of concrete, such as rational use of high-efficiency water-reducing agents, use of high-quality aggregates, high-quality For cement, use high-quality admixtures and add corresponding admixtures to change the composition of concrete.”
Li Wenyong glanced at him: Why am I, a small private enterprise, considering these things?
Li Wenjun added: "Even if the role of national defense is not taken into consideration and only economic benefits are considered, C60 concrete can create more architectural benefits than C40 concrete."
Li Wenyong said: "Tell me how to create it."
Li Wenjun said: "The higher the strength of the concrete, the thinner the columns and beams, the more the building area will be. This effect is most obvious on the ground floors of high-rise buildings. In the future, buildings will be built higher and higher, and viaducts and long-span bridges will become more and more The more concrete, the higher the strength and performance requirements for concrete. There are also some special buildings, such as large dams, which also have anti-missile requirements to prevent enemy damage. If you can provide a variety of high-performance concrete, will the market be huge? The wider it is, the better the benefits will be.”
Li Wenyong nodded: "Yes. I will try again and communicate with other research institutes."

Li Wenjun told Tao Guangming that he would take Li Shenxing and Li Jinyan to the air show to do odd jobs.
Tao Guangming looked shocked: "Do you have any humanity? How old are they? Are you so eager to use them? These are your sons and nephews. Let them finish college. You don't lack that little money. .”
Li Wenjun laughed angrily: "What nonsense are you talking about? I am doing it to let them make money for me. I am doing it to let them learn a lot. How can they earn as much as I spend on them by running around in one place? "
Tao Guangming muttered: "It's up to you. Anyway, I'm reluctant to let our family do this in September."
I went there to work as a waiter and guide. Being called upon by others and serving them.
I don’t know what Li Wenjun is thinking.
Li Jinyan is obviously the heir to "Wenjun Industrial".
The key is that Li Shenxing can't help when he's here like this, so he needs to have someone watch over him to prevent him from getting into trouble.

The reason why the aviation exhibition was finally chosen in early winter is because the southern seaside was the most comfortable at that time.
There is no drizzle, the temperature is between 18-22 degrees, and you won’t feel too hot even if you stand in the sun.
The sky at the seaside is also particularly clear in this season, like a huge piece of blue glass.
White flocculent and filamentous clouds float above it.
There are waves on the sea, and white seagulls fly between the sky and the sea.
The beautiful scenery alone makes people want to fly in a plane between the sky and the sea, chasing the wind and waves.
This time many foreign manufacturers and the military came to participate in the exhibition and visit.
On the one hand, it is because of Yang Shouzhuo's great energy. On the other hand, everyone is curious about the technological level of China's aerospace industry. At the same time, they are also interested in China, a large market with a population of more than one billion.
The big plane has already transported it.
Other small items were shipped with Li Wenjun and others.
This time they not only brought aviation equipment, but also some products from beverage factories, new products from daily necessities factories - tens of thousands of disposable paper cups and folding chairs from furniture factories, as well as airplane models and deformed toys.
The paper cups and drinks took up half of the truck.
Tao Guangming muttered: "We are going to the air show, what are we going to bring with us?"
Li Wenjun said: "These can make you smile from ear to ear."
Now through Wenjun Logistics Network, it only takes more than ten hours to go from "Wenjun New City" to Zhu City.
Including the layout and so on, it can be done in two or three days.
The indoor and outdoor booths occupied by Li Wenjun's products are not large, but they attract a lot of people.
The last time he participated in the US Air Show, he almost died from being busy indoors alone.
This time the domestic audience will be more enthusiastic and curious, so he had to prepare a few more drones and service personnel.
So he brought twenty staff members, twelve indoors and eight outdoors. They are all carefully selected beauties and handsome men. Half of them participated in last year's Frankfurt Motor Show and have rich experience.
Even this, he felt, might not be enough.
