Chapter 44 Cement made by soil methods
Chapter 44 Cement Made by Soil Method

Li Yu didn't seem to believe it when he saw that the red bricks that were cooked were not afraid of rain.
He asked someone to bring a bucket of water, poured it on the bricks, and then rubbed it with his hands a few times to prove that what he said was true.

A group of old men also tried to throw the bricks into the bucket. After a stick of incense, they took them out. They were still strong, and they didn't crack after a few taps with their hands.

Only then did I understand that what Langjun said was really true. This kind of cooked soil embryo is really not afraid of rain.

The villagers all felt amazing and ran to tell each other.

Of course, only within the scope of a few Zhuangzi, it is impossible for outsiders to know, but the steward has said that Langjun is looking for a loyal and reliable person, who would dare to ruin Langjun's major affairs.

In fact, Li Yu thought too much. The rules of the Tang Dynasty were not only strict, but the people also paid great attention to the protection of intellectual property rights.

For example, this red brick is fired, even if Li Yu doesn't say a word, outsiders can't inquire about the news in several villages.

Don't look at a few Zhuangzi with more than [-] people. If you want to know where the red bricks come from, don't even think about it.

The red brick was finally fired here. It should have been a big celebration, but Li Yu was not happy.
Just now, I was only concerned about excitement, but ignored an important thing. There is no cement or lime here at all. What do you use to build a house? ?

It is not impossible to use mud, but it is not very strong. The original intention of firing red bricks is to prevent the corrosion of rainwater.

In order to achieve the purpose of durability, if you go back and continue to build walls with mud, wouldn’t you laugh your teeth out?

But no mud, what do you use?

It was really like Zhou Yu from the Three Kingdoms, laughing and screaming for a while.

Reminds me of attacking with fire.I was very happy, but I immediately thought about it, how could you attack without the east wind?

Li Yu said to the crowd in frustration:
"When you built your house, what did you use to bind the soil embryos together?
Afraid that these old men would not understand, they stacked two bricks, gestured to the middle, and asked questions.

A group of old men have participated in house building, and at a glance, they can tell what the meaning of this gentleman's question is, the old men all said in unison, "Clay."

Li Yu didn't care much when she heard that it was clay, but she always felt that there was some inspiration to come out.
But no matter how hard I thought about it and how hard I tried, I just couldn't think of any bright spots related to clay, so I just stood still and my brain started to crash.

How could the nine old men who made red bricks know the inner world of this little man, what was he thinking?
In the middle of the period, one of the oldest heard Lang Jun asking about the secret of gluing adobe embryos,
It began to talk about the precautions and operation methods of how to use clay.

Where can Li Yu hear it? He only heard the oldest old man intermittently, spitting foam at the mouth, and said with great interest:
"...Lang Jun didn't know, the method of making this clay was handed down from generation to generation by ancestors, the local method..."

"oops!"

The old man was in the middle of his lively speech, and he was temporarily used to it. This little Langjun's wooden man-like state,
Suddenly, Li Yu's sudden slap on the thigh disrupted the ongoing release of the language organization, and immediately got stuck, and could no longer utter a single word.
Not only that, but he was also taken aback by Li Yu's sudden, oops sound,
Sixty-seventy-year-olds, in Datang with an average age of about 70 years old, are already considered rare products.

Not to mention Datang, even in the post-world, after 60 years old, is a standard retiree, not to mention in Datang where medical science is not developed,

What was the average life expectancy in the Tang Dynasty?During the prosperous Tang Dynasty, it was the most powerful country in the world, and the living standards of the people also improved a lot compared to the past.
The average life expectancy is also about 50-55 years old.According to the statistics of 5100 epitaphs in the post-world, the average life expectancy of the Tang Dynasty was 59.3 years old!
For the sample statistics of couples: the average age of male death after marriage is 62.3 years old!
The average age of women dying after marriage is 64.2 years old!When Du Fu was 48 years old, he wrote a masterpiece "Giving Eight Guards to the Guards", in which he wrote that "visiting the old is half a ghost".
It means that half of his relatives and friends have passed away.In other words, half of them didn't die.

That is to say, around the age of 50, half of the people are still alive.

To sum up, it is not in line with the consideration of official history to write indiscriminately in the work that the average age of people in the Tang Dynasty is 38 years old.

After all, the health of the elderly is not as strong and durable as that of the young.
With a sudden exclamation, Li Yu made the old man tremble slightly, and found such a result,
Li Yu didn't dare to act rashly. He knew that the elderly were most afraid of sudden shocks, and it was possible to be scared to death in the past.
So he persuaded softly: "Master, don't panic too much, someone just thought of a way that is more powerful and firm than clay,

This method cooperates with the cooked soil embryo to build a more durable house.

So I exclaimed, my husband doesn't need to worry, there are no outsiders here, they are all villagers from their own villages, so why worry about this. "

When the husband was in the Tang Dynasty, it was the title of the old man, not the father-in-law.Judges, don't get me wrong.

After the old man regained his composure, he slowly opened his mouth and asked:
"Thank you Langjun for worrying, the little old man is still in good health, and there is no major problem. I just don't know, what wonderful method did Langjun think of, which is more durable than the old-fashioned method handed down by the predecessors, making clay? "

Li Yu is still complaining about how stupid he is, thinking about industrialized cement production, which is not his strength, and has no way to start.
Moreover, in this era, even if you know the production method, you cannot extract the chemical raw materials you need.
There is no modern machining production line, so it is very distressing.

I was thinking about it, but suddenly I heard the old man say that clay is made using the earth method, and then I woke up, why do I have to build an industrialized cement factory?
Isn't there a way to make cement?

Although the cement produced by the old-fashioned method is not as industrialized as it is, it is comparable to the technological level of this era.

Moreover, the production process of the old-fashioned method is very simple, and many people in later generations know that,
The simple cement production method is simplified a lot, and the limestone, clay, and clinker are burned.

After using clinker and iron making, the remaining slag is milled together, and finally becomes a powder product.

This is the simple, cement production method, commonly known as earth-fired cement.

Looking at the diligent old man asking, Li Yu explained with a smile:

"So that my father-in-law knows that a certain person reads a lot, and I just heard from my father-in-law that the clay made by the soil method,

Just now I remembered that if the clay is cooked like this mud embryo, and then some burnt and broken stones are added, will a new high-quality clay be formed?If so, wouldn't it be great? "

Having said this, Lao Li can't help but sigh that knowledge is really too important. Without knowledge, if human beings want to make continuous progress, they will be much slower.

Looking at the crowd around me, there are probably more than a hundred children. If these people have different knowledge, they will be able to bloom in various ways when they grow up...

Li Yu suddenly had another idea. Since this is his own private kingdom, these loyal descendants are of course very important. If they are asked to read and enlighten...
