The first time he saw the hill-like limestone powder pile, Pei Ge'an was really shocked.

This storage pile built on the mountain is backed by a mountain on one side and hundreds of crooked ladders on the other.

All the crowd was like little ants, working around this pile of rubble.

Each of them was so dark that their faces could not be seen, and some of them even wore only a pair of calf trousers, and the ash on their bodies could be scraped off a thick layer.

This limestone powder pile alone is afraid that there are hundreds of thousands of tons, or even millions of tons.

It's really a lot of power, she originally thought that the demand for cement was great, and she was afraid that the supply would not be available, but when she saw the scene in front of her, she didn't know why, her eyes were a little astringent.

She took a deep breath, suppressed the boiling inside her, and turned her eyes to the other side.

Not far from the distance, above the river beach by the Han River, a large area of shacks was built, and the edge could not be seen in dense packs.

She was tempted and walked to the other side of the shack.

Gao Ban Feng Yiyong, the chamberlain in charge of the cement project, hurriedly persuaded: "Eldest sister, the environment over there is harsh, and there is a loss of view. ”

"It's okay, I'll take a look...... How are the preparations for quartz ore powder and dolomite? ”

Feng Yiyong hurriedly said: "At the beginning, the head of the palace confessed that it was necessary to prepare according to the ratio of ten to one, and it was already prepared, but it was blocked by this pile of powder, and I saw it when I went around." ”

Pei Ge'an walked in front like a big guy, followed by a large army of dozens of people, if she hadn't jumped up, she would really have the momentum of a big guy.

But he was short and short-legged, and he jumped up and down the hill like a naughty child.

Minfu's camp was on the hillside, some distance from the riverbank, and below it were pots and stoves.

The shacks are low, uniformly built with bamboo poles and wood, and covered with reed poles.

Pei Ge'an looked at it, and the camp was covered with hay on the ground, and everyone's bedding could not be seen in its original color.

The shack is less than two meters high, and everyone needs to bow their bodies to enter it, and they can't stand up straight at all.

She looked up and saw that the roof should be protected from rain, and the walls were double reed poles, which could keep out the rain, but not the wind.

"Can such a shack keep out the rain?"

Feng Yiyong said with a smile: "Of course you can, many farmers' roofs are also grass roofs, and it is no problem to use them for decades." ”

It stinks here, tens of thousands of people eat, drink and lazar are here, and all kinds of smells are mixed together, so that Pei Ge'an has no interest in going down to inspect.

"The people bring their own food?"

"Yes, there is a quota for the people in each place to serve, and when they come to serve, they bring their own food, and the court only needs to help them prepare a cauldron. Fifty people are in a team, divided into a cauldron, and two people are sent to cook food every day, and the others go to work. ”

There are too many places to complain, but Pei Ge'an has no more to complain about Yuwang.

The sanitary conditions here are so poor that in the afterlife, it would be a slave treaty.

But in her opinion, everyone was still happy, did not dislike such conditions at all, and worked very energetically.

It is really a hard-working nation, and no other nation in the world can compare with it.

"How many people are there at this site?"

"A total of 12,000 ......," Feng Yiyong pointed to the sand pile on the side of Yuliangping and said, "There are also 2,000 people responsible for fishing the sand in the canal, which is also under the control of here." ”

Pei Ge'an asked again: "How many people are there here in Hanjing now?" ”

"A full 100,000, and another 2,000 on standby."

Pei Ge'an was a little speechless, this nation fights and works, and it counts 100,000 people at every turn.

Her Basque people, at their most populous in history, were only 3 million, which is simply incomparable.

Standing on the hillside, she looked at the unfamiliar surroundings again.

In modern times, she has been here, there is a huge film and television city, amusement park, not far to the north, it should be Tang City.

But now, things are not people.

She stretched out her hand, and Xu Yongchang immediately handed a booklet into her hand and said softly: "Sister, it's too dirty here, we might as well go to the tooth shop to discuss it again." ”

The tooth shop is a place where the officials distribute work and put the tooth cards for the people, and they are also responsible for treating the injured and sick people, and there are several rows of brick houses, which are much cleaner than here.

Pei Ge'an nodded, and took the lead in the direction of the tooth shop, explaining as he went. "Now that the stock of raw materials is almost complete, several raw materials will be mixed together in the future, and they will continue to be fired and grinded."

Feng Yiyong was surprised: "Now this stone is almost as good as grain, not fine enough?" ”

Pei Ge'an sighed, now there is no vertical mill and ball mill, the delicacy of cement raw materials is not enough, even if the raw materials are complete, the marking is not enough.

She nodded and said, "It's just raw material, and then it's fired and milled." I'll have the blacksmith make a couple of pieces of equipment to grind the powder finer than the flour.

This is the next procedure, several of you in charge of the person to take a look, and a procedure cannot be less......"

Flipped the booklet to the two pages of the cement firing, handed it to Feng Yi to use them, and let them read it roughly first.

Pei Ge'an said again: "After a while, a few of you will go back to the Jiedu Embassy with me, I have arranged for the maid to transcribe the detailed process, and I will give you a copy when I go back, and each of you is responsible for a process, and in the next few days, I will hurry up and make a batch of samples." ”

Feng Yiyong couldn't help but ask, "Eldest sister, what is this cement for?" ”

Pei Ge'an smiled: "You can make the embankment indestructible, you can make the city wall indestructible, you can make the moat a smooth road, and you can build a strong bridge in the river." ”

The crowd was dumbfounded, and couldn't help but look back at the mountain of powder.

Is that really the case?

Lu Duosun had never paid attention to cement before, believing that this kind of thing was neither iron nor steel, similar to the brick kiln built in the south of the city.

Hearing Pei Ge'an say this, he reacted immediately, if it is really like what Sister Pei said, although this cement is not a weapon, I am afraid it is much more important than a weapon.

He immediately asked softly: "Eldest sister, in this way, isn't this cement worthy of being called the most important weapon of the country?" ”

Pei Gean nodded. "Building roads and bridges, building cities and canals, including building houses, this cement is very useful, and it is indeed an important weapon of the country."

Lu Duosun immediately instructed the entourage of the officials: "Immediately arrange for people to block this place, so that no one can master the whole process." ”

Although Lu Duoxun has not yet officially taken office, he is also the appointed soldier of the Hanjing Prefecture, in charge of weapons, vehicles, and the production and supply of grain.

In later generations, he belonged to one of the Standing Committee, and ordinary officials would of course listen to his arrangements.

Pei Ge'an smiled: "Don't worry so much, the craftsmen don't understand this, the whole set of processes, only Feng Yi can master them with these servants." ”

Lu Duosun asked again: "What about the Ministry of Industry?" ”

"It depends on the second brother's arrangement, we all listen to the second brother."

Lu Duosun said: "Such a country's important weapon, the process must also be known to the Ministry of Industry, only the Ministry of Industry, can this ...... Cement...... The factory was built to various places. ”

"I just have to produce it, let whoever produce, the second brother has the final say."

The group returned to the Jiedu Embassy, where Zhao Dezhao was busy receiving officials at all levels in the front yard, while Wang and Chen were also busy receiving officials' daughters.

Especially since they are pregnant, many of the ladies have brought valuable gifts.

The main hall was occupied, and Pei Ge'an didn't care, so he asked the chamberlain to open a vacant warehouse, moved more than a dozen Han couches and desks, and asked people to move the blackboard in his yard.

When he was in the East Palace, Pei Ge'an was still hiding, but when he arrived in Hanjing, he was much more public.

Whether it is the chamberlain or the guard, they have been instructed by Zhao Dezhao to protect her with the highest standards, so in the mansion, there are more people who befriend her than the two ladies.

Although it was an internal teaching, Lu Duosun also followed up with the middle court.

The others did not rush him, and specially prepared a set of tables and Han couches for him.

He originally wanted to take a pen, ink, paper, and inkstone, but when he saw that everyone else had a pencil, he asked for one and tried it.

Although I can't write the pen and charm, it is indeed much more convenient, and the writing is much faster.

A maid handed out a pamphlet to each of them to read first, and then surrounded Pei Ge'an into the backyard.

The booklet is not thick, only ten pages, and the cover reads "Ten Steps in Cement Production".

When I opened it, I saw that it was densely packed with small characters written in pencil, and the font was not very good, but it was concise and refreshing.

What he is not used to is that the font is actually horizontal, from left to right, but each sentence is separated by different symbols, and it is all in the vernacular, which makes people understand what it means at a glance.

But after reading the first few pages, from the process of crushing limestone to the necessity of various incineration and grinding, when it comes to the process principle, he does not understand.

If you ask other people, they only know a few processes to start preparing materials, and they can't understand the latter ones.

However, Pei Ge'an quickly changed her clothes, washed her face and came out, and in her hands, she also took a few white pens made of lime.

After a few words, she asked everyone if they didn't understand, and after asking clearly, she began to teach.

"The previous raw meal stocking process and process can be understood by illiterate people, and since you all understand it, I won't waste energy. Now, let's start with why these processes are needed and what they do.

Only by knowing the whole thing will you know why you are doing it, and you will not miss every step of the process. Know what it is, and why it is. ”

Lu Duosun also didn't expect that he would listen to a ten-year-old girl like a student after Zhou Jinshi.

But the girl in front of him was too demonic, and he didn't dare to question the other party at all.

In front of the blackboard, Pei Ge'an said in a crisp voice: "Why did I fire it in front of me, it was to make the stone brittle and easy to grind. However, from the beginning of raw meal to mature material, it is not for this purpose, but from physical action to chemical action.

As for what is physical action and what is chemical action, I will not talk about it for the time being, but only tell you about cement-related knowledge.

The first thing we need to understand is what the composition of the stone is and why limestone is used and not other stones......"
