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

Chapter 170: Fire cement using local methods! Wanchao craftsmen were shocked: High-end materials only require simple steps?

Qing.

Kang, Yong, and Qian, who were in different time and space, looked at the scene on the sky and fell into the same entanglement.

Buildings built with cement in later generations seemed to be very solid.

How about renovating the Forbidden City?

However, this idea only appeared for a moment before the three of them dismissed it!

Emperor Kangxi: The treasury has no money, how can we renovate the Forbidden City?

Emperor Yongzheng: The treasury finally has some money, how can it be used to renovate the Forbidden City?

Emperor Qianlong: I haven’t been to Jiangnan for half a year! It’s okay if the Forbidden City is not repaired!

Gu Sheng was still unfinished at this moment and watched the entire video again.

A few minutes later, Gu Sheng looked at the countless cement powder produced at the end of the video and nodded secretly.

Good guy, it is indeed an industrial production of cement, and many of the steps are completely different from what I have learned before.

Out of curiosity, he directly clicked on the comment area.

"Truth is Eternal: The blogger should explain in detail the manufacturing of indigenous cement. I think it is easier to get started than this industrial method!" 》

"Reply: Yes, we should elaborate on how to make cement when traveling back to ancient times? 》

"Reply: In fact, as long as you have the idea and formula, the process is pretty much the same. They all prepare raw ingredients and then stir-fry the mature ingredients, and then mix them into cement according to the proportion! 》

"Tang: I feel that using only pottery powder, lime, clay, and glutinous rice water, the adhesive produced is strong enough! 》

"Reply: If it is compared to ancient times, it is indeed enough, but for mass production, burst cement is better! 》

"Zhuang Yi Chui Tian Yi: There is a kind of cement substitute called "artificial pozzolana cement" that has a very simple process. The calcination temperature is 600-800. It can usually be achieved by carbon fire in a blast furnace. Although its performance is slightly inferior to Portland cement, it is Reliable enough too! 》

"Reply: If I remember correctly, the Burma Highway was made of this cement!" 》

"Reply: The total proportion of clay, adobe bricks, ceramics and other fragments is 75%, the proportion of quicklime is about 20%-25%, and the proportion of plaster of paris is about 0-5%, all are ground into fine powder, mixed and calcined. It becomes artificial pozzolan cement! 》

The heavy duty under the canopy was stunned for a moment at first, and then countless spectators exclaimed in amazement.

I just lamented that the process of making cement in later generations is a bit complicated and difficult to mass-produce, but I didn't expect that there is an alternative method now?

And this alternative method is countless times simpler than the previous processes!

Wan Chao's craftsmen were all shocked at this moment. Such high-end materials only require such simple steps?

Spring and Autumn Luban: How about more crafts like this?

Everyone in the Mohist family of Da Qin: Oops! Can cement still be fired like this?

Great Qin.

When the First Emperor Ying Zheng saw that comment appearing from the sky, his eyes immediately dazzled.

Good guy, isn't this what the mediocre Da Qin needs most?

Cement can finally be fired in batches!

The end of the Eastern Han Dynasty.

Zhuge Liang in the Three Kingdoms Shu region has also completed the initial experiment.

In the copper cauldron at this moment, a small basin of slightly black dust exuded a faint pungent smell.

But the people watching around didn't dare to take a breath. Even Zhang Fei, who had always made a fuss, took off his shirt at this moment and directly became a labor force for free.

"It should be fine!"

After Zhuge Liang spoke softly, Zhang Fei stopped instantly and looked at Zhuge Liang hurriedly.

"military adviser?"

"Can this really make cement?"

Zhang Fei's tone was filled with slight anticipation, but the unbelievable horror in his heart could never be erased.

The rest of the people in Shu also cast embarrassing glances.

Although it was late at night, everyone present had already been attracted by the scene in front of them.

Damn it!

If the cement in the sky can be restored, Shu Han will surely take the lead in today's troubled world!

As long as the land of Sichuan and Sichuan is built into an iron barrel-like defense area, one can naturally sit on the river and look at the Central Plains. However, many people are a little confused at this moment.

Is this pile of black ashes in front of me really the so-called cement?

The difference between this quality and the scene evolved by the sky curtain is really too big!

Zhang Fei frowned as he thought about it.

"military adviser!"

"Why do I think this cement has failed?"

Zhuge Liang didn't say much at this moment, he just took out most of the blue-black ashes from the bronze tripod, and then spread it flat on the ground.

While waiting for the cement to cool, Zhuge Liang has been paying attention to the changes in the sky.

After seeing a substitute "cement" proposed on the sky screen, Zhuge Liang's interest became more intense.

No matter whether the cement firing in front of you can be successful or not.

Zhuge Liang is already 70% to 80% sure of the plan given later in Tianmu!

After a few minutes, the cement had returned to normal temperature.

Zhuge Liang also carefully added water into it. As the shape of the cement changed, it seemed to coincide with the scene shown on the sky screen!

"Is it really done?"

"The military advisor is indeed a great talent. He succeeded in restoring the divine objects of future generations just by relying on the evolution of the sky curtain?"

"The wisdom of the military advisor is beyond my reach!"

"I've never seen it before. Just this lump of sticky stuff can actually build such a majestic building in later generations?"

Everyone said something to each other, although the tone was different.

But without exception, everyone knows that from now on, Shu Han's trump card to gain a foothold in the world has increased a little.

As for the other princes?

Even if it can restore the mystery of cement, how can it be compared with the unique geographical conditions of Sichuan and Sichuan?

Great Sui.

Li Chun, a famous craftsman, has just completed the construction of Zhaozhou Bridge.

I thought that this was the work of my whole life and that no one could surpass it throughout the ages.

But after seeing the so-called efficacy of cement, Li Chun fell silent.

If this kind of cement can help, Zhaozhou Bridge can obviously be made even more perfect!

"Tianya Taiming: Good guy, you know what I've been through!" I started by making table salt using local methods, and then moved on to iron smelting and wine making using local methods. Why is it that I am now directly recommended to make cement? 》

"Reply: +1! I’ve been crazy about these lately too! 》

"Reply: Do you have the hard core that I got? Yesterday I saw a video of a cannon made using local techniques. I was so dumbfounded by it! 》

"The Will of Eternal Life: Everyone is not rushing to travel through time, right?" 》

"Reply: I guess you do too, haha! 》

"White Ivory Tower: I understand time travel so well. I can go from night to dawn as soon as I close my eyes and open them again!" 》

"Old Boy: Let me just say that watching these videos is useful!" 》

Huh?

The moment he saw these comments appearing, King Wan Chao's eyes immediately narrowed.

cross?

They have seen this topic on the sky screen countless times.

Although he didn't want to admit it, King Wan Chao still had countless sighs in his heart.

It would be great if I could travel through time. I will definitely extend the reign of Great X through the ages!
