The short video shows the ancient times, and the emperors cried with envy!

Chapter 169 How is cement produced? The Mohists were shocked: Everything was ready, all it needed was proportions!

As a man who grew up in the Sichuan and Chongqing areas, Gu Sheng has lingering fears about that mountain.

Ahem, nothing else.

This thing really has 100% restraint properties for men from Sichuan and Chongqing.

After chuckling, the screen in Gu Sheng's hand quickly started to slide.

[How is cement produced? Take you through the entire cement production process in five minutes! #cement#cementfactory#increased knowledge#documentary]

[Cement is known as one of the greatest inventions of mankind in the 20th century. With it, both military and civilian construction will usher in earth-shaking changes! 】

[Everyone knows that the so-called cement refers to a product formed by grinding and mixing limestone, clay, and iron ore powder in proportion! 】

[But in a narrow sense, the mixture at this time is called raw meal, and the product calcined at about 1450 degrees is called clinker. Then the clinker and gypsum are ground together and mixed in proportion to be called cement. 】

[In our definition, the cement obtained by this method is called ordinary Portland cement. Cement is generally divided into ordinary Portland cement, Portland cement mixed with mixed materials and special cement. 】

[Portland cement mixed with mixed materials is added to ordinary Portland cement in proportion and with certain processing procedures to achieve special effects! Such as slag cement, pozzolanic Portland cement, fly ash Portland cement, composite Portland cement, etc. 】

As the voice-over sounded, the picture on the sky screen changed instantly.

It was a ball of blue-gray powder.

As liquid is added, the cement begins to become thicker.

The surrounding scenes also began to introduce the role of cement.

In less than half a minute, several methods of using cement were demonstrated.

At this moment, Wan Chao looked at the canopy scene and his mouth opened wide into an "O" shape.

cement?

Never heard of it!

It wasn't until the curtain explained the role of cement that countless viewers were stunned.

Good guy, it turns out that so many buildings in later generations were made of this material?

It turns out that cement can actually strengthen city walls?

It turns out that cement can actually form what is called concrete with gravel!

It turns out that cement is the cornerstone of the construction industry!

The audience all looked directly at it. If cement could be made, wouldn't it mean that towering buildings like those in later generations could be built?

Great Qin.

When the First Emperor Ying Zheng saw this scene, his ambition could no longer be restrained.

It is also a later technology, but in his opinion, this so-called cement is much more important than soap.

Didn’t you see that it was rated as the most important invention on the marquee?

At this moment, the First Emperor Ying Zheng only felt lucky. Unexpectedly, Tianmu did not let him down and directly passed down this shocking craftsmanship for making sacred objects.

Given this opportunity, wouldn’t it be a waste of resources if we didn’t learn?

On the one hand, he asked the historian to write down the contents of the sky, and on the other hand, he asked the Mohist giant to come over.

It is best to leave the research on this kind of later technology to the Mohists.

Little did they know that at this moment, everyone in the Mo family was already eager to try after looking at the cement raw materials exposed on the sky.

You must know that before this, lime was generally used for reinforcement when building city walls in the past dynasties.

Although effective, lime is not cheap.

If you want to get it in large quantities, the cost is extremely high!

But now, a perfect alternative has been given on the sky screen, and that is cement.

It’s a pity that there are still some specific proportions missing!

But these can still be tried after all. The real headache is the high temperature.

If we follow the idea of ​​​​iron smelting, we simply cannot reach such a high temperature by using only firewood. Fortunately, they have found a solution from the idea of ​​blast furnace ironmaking. What wood cannot do can be left to charcoal!

Everything is ready, all that's missing is proportion!

In the Tang Dynasty, Xuanzong Li Longji showed his magnanimity as an emperor of the Tang Dynasty at this moment.

He didn't know the utility of cement yet, but he knew very well what changes such a thing could bring to Datang!

Chang'an City of the Tang Dynasty was already considered the pinnacle of the world, but compared with the high-rise buildings of later generations, this was nothing at all.

And now, he finally found an opportunity!

"Preach my will!"

"It is necessary to make the so-called cement. If there is no formula, just try it bit by bit!"

"The raw materials have been given, and I believe that the craftsmen of Datang will definitely live up to expectations!"

Ming dynasty.

Lao Zhu looked at the changing scenes on the sky and had no time to pay attention to Queen Ma's teasing.

This so-called cement?

It seems to be some kind of material that bonds city wall bricks!

Recalling the prosperous scenes of later generations, Lao Zhu's heart suddenly moved.

If one could learn such a craft, wouldn't it be possible to build a city wall dozens of feet high outside Kyoto!

In this case, who else can break through the Imperial City of Kyoto?

……

[This is the largest cement factory in Latin America, producing more than 320 million tons of cement every year. All mechanical operations are controlled by a central console! 】

[After adding the limestone and clay from the quarry to the container, add the iron ore mined from another mining site! 】

[First, add all types of ground materials into the silo according to proportions! 】

As the picture changed, the rough material ratio of cement briefly appeared on the sky screen.

At this moment, countless princes and princes from all dynasties were all excited for a moment.

Now that you have the proportions, you only need to follow the diagram to find out.

But then the production process displayed on the marquee made them completely dumbfounded.

In the huge cement factory, all of them are mechanical creations that have never been seen before.

That kind of fully mechanized production method is hard to understand, let alone learning it!

If Tianmu hadn't given relevant hints before, I don't know how many people would have vomited blood.

Great Qin.

After everyone in the Mo family got the proportions, they immediately started division of labor and cooperation. In less than three minutes, the so-called "raw materials" were prepared.

Looking at the pile of dark powder, countless Mo family disciples all showed excited expressions.

Now it only needs to be baked at high temperature to form real cement!

Ming dynasty.

Yongle Emperor Zhu Di looked at the various processes related to cement, and his ambitions became more and more intense.

This is not just a material, but also a treasure that can save the Ming Dynasty's treasury.

lime? coal? iron ore? Clay?

For Zhu Di, who owned the Ming Dynasty, there was no cost. The only thing that needed to be considered was how to simplify those complicated processes.

This allowed cement to be manufactured in batches in today's Ming Dynasty.

As long as such a wonder can be created, Zhu Di doesn't believe that those princes and ministers will not be tempted?

Just kidding, the house made by this thing is at least fireproof!

I don’t know how much security has been improved!

For those princes and nobles, it is a priceless best-seller!

As long as we can get back the money from those nobles to replenish the national treasury, is the great cause of the Ming Dynasty still far away?
