Uncle Lin fell from the sky [Red Mansion + Qing Chuan]

Cement is something that is not unfamiliar in previous lives, but most people don’t know how it is made. Of course, Lin Zizhen is not very clear, but fortunately he has a shopping system in his hand. , Standing on the shoulders of giants, Lin Zizhen copied down the cement making methods he collected according to the calabash.

Pick a certain amount of sand and stones, mix them together according to the proportion, and spread them on the ground. If the weather is good, it will be as hard as a stone after a few hours.

This sounds simple, but it is not so easy to do. Lin Zizhen chose Portland cement with a relatively simple production process.First, I collected some limestone and clay as the main raw materials. It took a lot of effort, and I beat and beat at home every day. Then I crushed these materials, ground them into fine powder, and made them into raw materials. I went to the outskirts of Beijing to dig them. Simple and reduced version of the small hole, the clinker was calcined with great difficulty, and finally a certain amount of gypsum was mixed into the clinker according to the proportion, and then ground again.

Only then did I get a small half bag of cement.Lin Zi really thought over and over again how to solve the problem of tempering limestone in making cement. After all, it will be difficult to produce cement in large quantities to meet the needs of production roads only by manpower.While carrying the cement, he hurriedly ran to the fourth master's mansion.

"Come, come, the time to witness a miracle has come. This is what I'm researching recently." Lin Zizhen said excitedly to the surrounding fourth master, Hong Hui, and Kang Le, Hong Yun.

Before when he was tinkering with cement at home, he knocked on the mansion and made a lot of noises, which aroused the curiosity of a few children. Faced with the curiosity of a few children, Lin Zizhen only knew it after a few days of mysteriously talking about it. Now, then he will do a trick for everyone.

Every time the children rest and take a bath, they often run around the capital. Boys, in the eyes of fathers, are rarely kept in captivity. After the fourth master assigns guards to the children, usually the children want to go out Let me tell you, they are rarely stopped.Juggling is often seen under the Hutong Bridge. Even though they already know the mystery behind the juggling, it doesn't prevent them from continuing to watch.

So I was looking forward to the tricks that Lin Zizhen said, and now they all surrounded Lin Zizhen curiously.Lin Zizhen asked people to fetch water, and said to the children and fourth master: "Although I can't touch stones to gold, but I can cast a spell now, and I can turn these powders into hard stones."

Hearing that these gray powders were turned into stones, Kangle and Hongyun's expectations that were visible to the naked eye were reduced by more than half in an instant, but the fourth master was very keen, and his eyes lit up all of a sudden. If what Lin Zizhen said could really come true, then this The usefulness of things is great.

Building roads, building bridges, and embankments...

Thinking about it this way, Fourth Master eagerly asked: "How do I get this thing?" As for whether it's real or not, I'll find out if I get it out and have a look.

"It's like living mud, just add water and mix it well, and spread it on the ground."

As soon as Lin Zizhen finished speaking, he saw that the fourth master had already picked up the tools, and started to work without asking his servants to help.The amount of cement that Lin Zi really made was not much, and it was adjusted in a while, and then several children joined in excitedly, just like playing with mud, holding wooden blocks to spread the cement on the ground, and there is still a small part. Used to pile up a small vertical pillar.

It happened to be July at this moment, and the capital was hot and dry. When the sun set, the cement on the ground had solidified, and I watched the cement turn into a hard ground bit by bit.

In fact, not only the fourth master and the children were surprised, but even Lin Zizheng was deeply moved. In the past life, they used sparse and common things, which were often overlooked by others. Few people think of its importance, because such an invention is in the world. It can be seen everywhere in life.

But in ancient times, he got the cement out from the beginning to the end according to the assistance of the materials. If it hadn't been opened and hung, the process would have been really not easy.

Seeing the cement forming bit by bit, Lin Zi was inexplicably moved and admired the original inventors more and more. It was hard to imagine how they observed carefully and devoted themselves to research to discover the truth of chemistry in nature. Substances, through ingenious methods, let these things become what human beings need.

There are more such inventions, and it is precisely because of these outstanding people who continue to work hard in their own fields that human beings can survive and continue to improve the quality of life and continue.

When Lin Zi was really wandering, the fourth master was knocking hard on the concrete floor, and the thin concrete pillar was as hard as a rock. This is a good thing. If it is used to build roads and dams, it can not only save Time, this performance is as hard as a rock, and the service life can be extended several times.

Not only can it save a lot of expenses for the court, but it can also strengthen the connection with the local area. Most importantly, it can contain or alleviate the flooding of the Yellow River to a certain extent.

I just don't know if this thing is difficult to get.

Thinking about it this way, the fourth master stared at Lin Zizhen with bright eyes and said, "Is the raw material for this thing hard to get? Can it be mass-produced?"

Hearing this, Lin Zizhen came back to his senses and said: "The raw materials are not difficult to find, they are very common, and they are quite cheap. I just think of mass production, and there are some troubles in forging. I need to figure out how to solve it."

"Well, since the cost is low, then let the Ministry of Industry think about these problems and try to solve them." The emergence of cement may help the Ministry of Industry solve the task of building official roads and commercial roads this year.

I was very happy to see fourth master showing his emotions rarely.Lin Zizhen bumped into the shoulder of the bumper, and said with a playful smile: "How about it, I am quite interested."

Although he dislikes Lin Zizhen's frequent appearances, it is because he takes the lead in the front, and the younger ones in the family also follow suit, especially Hongyun, who likes to imitate Lin Zizhen's behavior more than Kangle, and he has done it several times. Catch this boy, lie on the kang with his legs crossed, shaking his legs.

But at this moment, I really got benefits from others, as long as I endured it, I didn't reprimand others.After dinner, it was getting dark, so fourth master left him behind to rest at the mansion for the night.

But Lin Zizhen gave the method of making cement to the fourth master, only saying that he read it in a foreign book, and by the way emphasized the name of the discoverer who invented the cement, and put the matter aside.

Then he returned to the previous virtues, happily took a few children, squatted in the room and started tossing, doing some small experiments, and asked for some white vinegar from the kitchen. It turns red, which is the redness of acid in the simple acid-base indicator.

They made a fuss for a long time, until Su Peisheng, who was sent by the fourth master, urged them for a long time before going to rest.

Si Ye moved very quickly. According to the method provided by Lin Zizhen, the Ministry of Industry conducted another round of experiments. Once the performance of the cement was determined, the entire Ministry of Industry was overjoyed. They began to think about how to achieve mass production. It can be produced in small batches, but slowly, the production volume is getting larger and larger.

After satisfying the government's own use, it also began to be listed for sale, which not only saved a lot of money for the Qing Dynasty, but also made a lot of money in turn, but this is a later story.

At the same time, Emperor Kangxi, who was far away in Mongolia, also received a memorial from the fourth master, and inside it was Lin Zizhen's plan for building a technical school.

Emperor Kangxi looked at this detailed plan, and the idea was good, but building a school house was not so easy. Looking at the subjects that Lin Zizhen had planned, he knew that a huge investment was required in the early stage, not only money, but also follow-up needs The supplies are huge.

And the imperial court doesn't have that much money for him to try and make mistakes.Thinking of the eccentric memorial handed up by the old Shangshu of the Ministry of Finance a few days ago, he thought that he spent too much money, but the southern tour and the tour outside the Great Wall were all out of consideration for the Qing Dynasty.

He just for fun?This time, even the subsidy of the accompanying ministers was taken from his own private treasury, so the old minister was not satisfied, and threatened him with quitting at every turn. What could he say? The accounts were filled up slowly by relying on the old Shangshu's careful selection.

Even if he was wronged, he could only write a letter with good words to appease him. Who told him to pay a large amount of money from his private treasury at that time, so he was dizzy and paid back the debt, so he wrote a letter and went back to reprimand him.

Emperor Kangxi quickly restrained Feiyuan's thoughts and concentrated his energy on the plan. After all, he was a young man, too idealistic, and he didn't want to turn to the end. There were a few large characters written on it, and the funds were self-raised.

Emperor Kangxi, who didn't want to respond at first, quickly changed his mind, picked up the cinnabar pen, and wrote the flamboyant Yun.Young people want to do things, and they are dedicated to the Qing Dynasty and the people. How to directly suppress their enthusiasm must give them more opportunities to grow up.

After all, he is indeed the young man he is optimistic about. It would be great if the court could have more young people like this.

Of course, these forests are really unknown, and when the emperor allowed the news to come back, they immediately started to act.Fortunately, Emperor Kangxi did not stingy to the end, but allocated a territory for Lin Zizhen, which was a little far from the capital, but fortunately, the territory was large.

The fourth master also gave Lin Zizhen a gift. According to the plan written by Lin Zizhen, he himself drew an architectural design drawing, not to mention not only beautiful, but also functional.

The school was under construction for a short time.Before he started soliciting sponsorship, Daiyu knew what her uncle was preparing for recently, so she donated a sum of money with a wave of her hand.

Afterwards, Sifujin, Honghui, and Da Gege also knew about it. They not only donated a sum of money themselves, but also went to mobilize their own network to help Lin Zizhen promote Lin Zizhen among their sisters-in-law and cousins.

In this way, no matter what the reason was, these princes of the Qing Dynasty and their Fujin all donated a sum of money one after another. With the joint efforts of the huge royal family, Lin Zizhen got a large sum of money here. Funds, and he doesn't even need extra alms.

Lin Zizhen counted the money with a smile, and recorded the amount donated by everyone in detail.

When it was the first technical school in the Qing Dynasty, Lin Zizhen specially ordered two tall monuments to be erected in the center of the school. One of them was engraved with the names and amounts of the people who donated to the school. Lin Zizhen didn't ignore their names, and asked for their consent to engrave their names completely on it.

Except for the third prince who complained about this matter, the other princes all acquiesced.The good guys let Lin Zizhen do it, they don't want to play the bad guys in Fujin.Otherwise, there will be a period of time when he will be annoyed by his own Fujin.

The other piece is left blank, Lin Zizhen intends to use it to record the outstanding figures who have gone out of this school.
