The Mausoleum of Qin Shihuang was born, and my immortal identity was exposed

Chapter 84 The Romance of Reinforced Concrete! (Please collect, please recommend!!!)

After talking about the method of making cement, everyone went back to the living room, sat at the dining table and changed cups.

Li Shimin held tightly the white paper that Jiang Sheng gave him that recorded the cement production method, as if he had found a treasure.

It's just that the words written by the immortal master are a bit ugly...

For an emperor who appreciates calligraphy very much, Jiang Sheng looked at the words crookedly written on his mobile phone, which made him quite uncomfortable.

But it doesn't matter, although the words are a bit ugly, but what is recorded on it is the country's most important weapon.

Jiang Sheng naturally didn't know what Li Er was thinking, and said with a sigh:

"You can ask someone to study this cement carefully. The ratio I mentioned is only a rough idea after all."

"If you break it apart and talk about it, the doorway inside can be talked about for a long time."

"With different proportions, the performance of cement is also different."

"With different auxiliary materials, the properties of cement are also different."

"Some harden quickly, some have high strength, some have strong acid resistance, and some have low heat release..."

Jiang Sheng said a lot, making Ying Zheng and Li Shimin dizzy.

"There are so many types of this simple cement?" Ying Zheng sighed.

Li Shimin rubbed his swollen eyebrows, he had never heard of many things Jiang Sheng said, so he should listen to the scriptures.

"It seems that you don't understand, let me tell you something intuitive!"

Jiang Sheng smiled, as if to open the eyes of these ancients.

"If it's just cement, the effect won't be that terrible, but if this thing is combined with steel bars, it will be terrible!"

"Steel is an iron-carbon alloy obtained by smelting pure iron and carbon."

"A steel bar is a straight or coiled steel made of steel."

"Do you believe it? With this cement and steel bars, you can build a tall building of hundreds of meters!"

Li Shimin wondered, "How high is a hundred meters?"

Ying Zheng, Meng Yi and Wang Ben were even more confused.

As soon as he opened his mouth, he was interrupted, and Jiang Sheng was suffocated for breathing.

Forget that the unit of rice is an imported product...

Jiang Sheng laughed awkwardly: "In other words, a tall building of hundreds of feet!"

In the Qin Dynasty, one foot was about 23 centimeters today, and in the Tang Dynasty, one foot was about [-] centimeters.

One zhang is ten feet, and now the tallest building in the world is the Burj Khalifa in Dubai, with a height of 820 meters!

"Old Li, do you know about Yongning Temple Pagoda?"

Li Shimin nodded. Although this splendid temple was burned, it still left a strong mark in history.

As the tallest building in the Northern Wei Dynasty, many people still compare it with the "Heaven" built in Wu Zetian's time, arguing who is the tallest building in ancient China.

Lao Li certainly didn't know about the "paradise" built by later generations, but he had certainly heard of the 130-meter-high Yongning Temple Pagoda in the Northern Wei Dynasty.

Jiang Sheng chuckled: "With this cement and steel bars, the building can be several times higher than the Yongning Temple Pagoda!"

Although the Burj Khalifa is not a pure reinforced concrete project, the height of the concrete structure is 600 meters.

Sure enough, Li Shimin was horrified: "Isn't this as high as the clouds?"

He closed his eyes and imagined, but he couldn't imagine that majestic picture.

"That's not all, the product of cement and steel bars can also be used to build water conservancy projects such as dams!"

"Old Zhao!" Jiang Sheng looked at Ying Zheng, "Did you know Dujiangyan?"

Ying Zheng shook his head, a little dazed in his eyes.

Jiang Sheng was embarrassed again, and patted his forehead: "Qian, it's Qian."

"The immortal master said this!" Ying Zheng suddenly realized, "I naturally know that it was created by Li Bing, the former prefect of Shu County, and his son."

Dujiangyan is also a miracle in the history of water conservancy projects in China, and it is still playing a role today.

It should be known that in ancient times, the land of Shu was either flooded or droughted, but later it was called the "Land of Abundance".

Here, the role of Dujiangyan can be described as not small.

At that time, King Qin Hui accepted Sima Cuo's suggestion that "if you win Shu, you will win Chu, and if Chu dies, the world will unite" and conquered Shu first.

But until the period of King Qin Zhao, the role of the land of Shu was not reflected.

The root cause is that floods are difficult to manage.

And Li Bing and his son were ordered by King Qin Zhao to turn the land of Shu into the granary of Qin.

The key to this is to solve the flooding of the Minjiang River.

The water flow of the Minjiang River is extremely fast, and it is easy to break the embankment when it reaches the irrigation mouth. In addition, the sediment brought by the water flow continuously raises the river bed, making it extremely difficult to control.

Li Bing first spent eight years, using the principle of heat expansion and contraction, that is, the method of burning water and pouring water, to forcibly chisel out a gap in Yulei Mountain, which is called the "treasure bottle mouth".

But at this time, the water diversion effect was very poor. Li Bing and his son led people to build a water diversion weir upstream, and filled pebbles with bamboo cages and piled them in the middle of the river, forming a small island, which was named after its shape like a fish mouth.

In this way, the Minjiang River was divided into two parts, the inner river and the outer river.

The Outer River is used for flood discharge, while the Inner River enters the Chengdu Plain from Baopingkou.

At the same time, Li Bing and his son also built a flying sand weir at the mouth of Baoping.

These three important components ensure the normal operation of Dujiangyan.

The most amazing thing is that, in this way, Dujiangyan has achieved the astonishing effect of "dividing water into [-]% and dividing sand into [-]%.

It not only ensures the demand for agricultural irrigation, but also prevents the invasion of flood disasters, and also solves the problem of sediment deposition in the water flow.

Since then, Shu has gradually evolved into the prosperous "Land of Abundance".

"Old Zhao, Dujiangyan, uh, the Yancheng just divided the water flow of the Minjiang River."

"But with this cement and steel bars, the entire river can be blocked, and the amount of water in the downstream can be adjusted by you, so that you can rest easy regardless of drought or flood."

As Jiang Sheng spoke, he thought of the Three Gorges Dam.

This is also an insurmountable monument in the history of hydraulic engineering.

Ying Zheng was a little dazed when he heard that, what a majestic scene it must be to be able to stop a river.

"There is also the bridge that is several kilometers long, directly across the river, and crossing the river has become extremely simple."

"A great man sighed when he saw this scene: a bridge flies from north to south, and the sky becomes a thoroughfare!"

"A bridge flies from north to south, and the natural moat becomes a thoroughfare." Several ancient people present silently recited this poem, chewing on its meaning.

Meng Yi lost his mind, and murmured: "Master Immortal, can all of what you said be done by human power?"

"I'm afraid only immortals can build such a magnificent building?"

Jiang Sheng laughed dumbfounded, and shook his head: "Wrong! These are not miracles, they are all made by manpower."

"Believe me, whether it is Daqin or Datang, one day, you can do all of this!"

Hearing Jiang Sheng's slapstick words, Ying Zheng and Li Shimin's eyes filled with uncontrollable pride and ambition.

Then wait for a natural moat to become a thoroughfare!
