The specific process of cement, dusk really does not know, only know that limestone, gypsum, iron and sand are probably used, there are two processes of crushing and heating, of which the heating temperature should be about 1,500 degrees.

Fifteen hundred degrees, at the current level of the Ming Dynasty, is a bit difficult, but it is not impossible to solve, it is necessary to manufacture a blower, and it can be achieved by using a blower and pulverized coal.

After telling Lin Zhendong and the other four masters what to make a thing out, what characteristics it has, what materials it needs, and what process it will probably go through, the four masters were dumbfounded.

Commander Huang, you turned your mouth twice, but we are all black-eyed about how to operate, and we don't even know the proportions.

How?

Dusk smiled and said that there is no hurry, there is time for you to explore, and it can be solved within three years.

But there is no way to build high-rise buildings, at most two or three floors, or learn from earth buildings and round buildings, which cannot reach the number of high-rise buildings built with cement, after all, private houses cannot be like yellow crane towers and the like.

Lin Zhendong and others are helpless, what's the matter, the owner's money is really high, let's do it.

In order to ensure the process, such as the crushing and heating process, because there is no limit to the industrial level at present, what electric motors are not thought of, all manpower.

In other words, it is necessary to develop a manpower blower and a manpower grinder.

Actually, it's not that hard.

As long as you make good use of bearings and gears, you can make sure that both of these things can be clucked out.

With the continuous layout of Dusk, the project of Huawei Real Estate Branch has advanced step by step, and the cement workshop has also entered the initial stage of manufacturing materials.

The blower is simple, mainly using cowhide to create an enclosed space, then making fan blades from wood chips, making transmission bearings and gears from iron castings, and adding a crank.

The manpower grinder is also similar to the principle, two samples were made, one is the use of the principle of stone grinding, the other is the use of the principle of pestle nest, after actual practice, it was found that the manpower grinder with stone grinding as the prototype has the best effect and the highest efficiency, so mass production.

It's a matter of a few paragraphs, but it's actually a lot of difficulty to operate.

For example, casting molds, this is a big problem, fortunately, the Ming Dynasty is not lacking is skilled craftsmen, there must be brave men under the heavy reward, the use of sand casting molds has been successful, of course, the sand is added to the gypsum this viscous agent.

As for whether there is a reaction during the casting process that leads to a gradual change in performance, Dusk does not care, this can be found and solved in practice.

That's how science progresses.

Without hard work, industry will never progress.

Therefore, the cement workshop is a huge gold hole, the investment is more than the original Zhongshan workshop, Zhongshan Workshop after all the glass production is experienced, just to improve the process, there is a way forward, and the research and development of cement is completely zero point start, step by step, Lin Zhendong just recorded the experimental data of the rice paper, piled up in a small room.

So every time Dusk saw the recorded data of the whole room, he was secretly smiling bitterly.

Harm.

I used to see it, the protagonist traveled to ancient times, invented modern mechanized equipment across the era in minutes, and all tanks came, and now it's funny to think about it, you must know that just a seamless steel pipe is an extremely difficult technical problem to overcome, not to mention those professional quenching and annealing heat treatment processes.

A small step for science and industry, it takes time and countless trials to get it right.

How difficult.

So until now, dusk only dares to tinker with what soap lotion or something, glass this is because the times have been, and the recent blowers and crushers are all rudimentary versions, after the development of industry, driven by demand, it depends on whether there are enough talents under the big tomorrow.

Talent?

A word wakes up the dreamer.

Leaving the cement workshop in a hurry at dusk, he went straight to King Yan's mansion, found Zhu Di, and was out of breath, "Your Majesty, there is a big event, a big event related to the Ming Dynasty!" ”

Zhu Di was splashing ink, and he couldn't close his chin with a smile when he heard the words, look, look, this kid is now a courtier.

Ming millennium?

Which dynasty has had millennia since ancient times?

As the Son of Heaven listened to this, and it was said in a hurried tone like dusk, Zhu Di took it for granted that he was coming from the heart rather than patting on the back, and said happily: "Don't worry, don't worry, just say it smoothly." ”

Motioning to the dog for tea.

During the tea at dusk, I glanced at the imperial desk and found that there was a tiger skin next to it, which was still very complete, "Surprised, Your Majesty went hunting?" ”

Zhu Di shook his head, "No, Yisha came back for a trip, and he sent the tiger skin." ”

It's also lost!

Dusk regretted greatly, "It's a pity that Weichen came late and didn't see this talent." ”

The cattle who completely included the Heilongjiang River Basin in the territory of the Ming Dynasty are really no less than Zheng He, and they are fully qualified to be a famous figure like Zheng He.

Hearing this, the dog on the side was a little gloomy.

Although he is very loyal to serve by Zhu Di's side, this inner eunuch, in fact, his dream is to become the pillar of the Ming Dynasty like Zheng He and Yizha.

Zhu Di saw it in his eyes, and his face was silent.

When the dusk was over, he asked, "Say, what do you want to say about the things related to my Ming Dynasty." ”

Dusk immediately said: "Your Majesty, have you ever heard a word?" ”

Zhu Di bowed, "You say." ”

Dusk said seriously: "Talent is king." ”

Throughout the ages, it is the productive forces that have promoted the development of history, and this is the truth in political textbooks, but the productive forces are also people-oriented, so talent is also an important factor in social progress.

Make the best use of things and make the best use of talents.

If the king can do this, even if it is a feudal dynasty, it can continue to progress, and even with the progress of society, some changes occur, and the Ming Dynasty may enter the constitutional monarchy.

Of course, the twilight of this thing is not counted now, and he doesn't know what the Ming Dynasty should do in the future, a constitutional monarchy? Republic? Capitalism? Socialism?

I don't know.

The most ideal is, of course, socialism, but at dusk it is uncertain whether the development of the Ming Dynasty has the conditions to enter socialism, and if you want to enter socialism, you must overthrow the imperial power, which is a very unrealistic thing.

It needs to be broken.

But these things are a hundred years after death anyway, so don't think about it for the time being.

Said: "Now the Ming Dynasty has been like the scenery of the Tang Dynasty, the weather of the coming dynasty of all countries, the current territory of my Ming Dynasty, the local skilled craftsmen Crouching Tiger, Hidden Dragon, overseas strange people are coming to the end, at this time, it is the world's talents together, greatly reused, to make the best use of their talents to promote the prosperous world, is to the minister, should be advocated by His Majesty, in Shuntian and Yingtian to establish two talent pools! ”
