I make a popular science video and all the emperors learn from it!

【It’s not difficult to tell how cement is made.】

【Please watch a short video below to learn it easily. 】

The text on the light screen disappears.

A short video instead

【"Cement is the second most consumed substance on earth after water."】

【"It is a gray powder used to make concrete"】

【"Also used for paving bricks, building dams, or laying reservoirs, etc."】

【"It's the glue that holds homes and buildings together, and the product has a long history"】

【"Cement has high strength, is relatively hard after setting, and can effectively prevent fire and water."】

【"To make it on a large scale requires explosives and kilns"】

【"There are three difficulties in making cement"】

【"The first is to find raw materials. The main raw materials of cement are limestone, clay and iron ore. In addition to the"540", coal powder needs to be added to assist the production."】

【"The ratio of the four materials is roughly as follows:"】

【"Limestone: 67%~75%, clay: 10%~15%, iron ore: 0.5%~1.5%, coal: 8.5%~11%"】

【"The specific proportion can be adjusted according to actual conditions"】

【"Limestone, also called limestone, is a common stone"】

【"Clay is commonly used in making porcelain and is distributed in China like iron ore."】

【"The second difficulty lies in high-temperature calcination"】

【"To produce cement, you need to add an appropriate amount of pulverized coal to the ground raw material, then put it into the kiln and calcine it at a high temperature of thousands of degrees."】

【"The ancients used to make iron at a temperature of 1500 degrees Celsius"】

【"The iron-making kiln is used to calcine cement, which is not a problem"】

【"The third is to crush the raw materials"】

【"After calcining the clinker, gypsum needs to be added and ground into fine powder."】

【"A hammer crusher is needed here"】

【"Its structural design is as follows:"】

【...】

【"But there was no electricity in ancient times, so water flow could be used instead of electricity."】

【"Overcome these three problems and you can create cement"】

【......】

After reading this, the ancients exclaimed

"The raw materials for making cement are so easy to obtain!"

"Yes, there are big stones, clay for making porcelain, stones for making iron, and coal that are common in the mountains."

"Is the cement made in this way really as useful as the light curtain says?"

"It's a pity that we don't have explosives. If we want to mine the rocks on the mountain, I'm afraid we won't be able to dig them out with our hands."

"Alas, we can only rely on the court."

"......"

Qin Dynasty.

Ying Zheng stared at the video intently.

He kept saying:"Good, very good, the raw materials are so simple and easy to obtain."

"It just so happened that the black powder that had been manufactured recently had no place to use it."

"Just use it to blow up mountains for now."

"It's just that this hammer crusher needs to be researched by the Mo family and made as soon as possible."

Ying Zheng has already thought of the huge value of cement.

The Great Wall built today requires the use of glutinous rice, which is very luxurious.

If cement is used instead, a lot of food can be saved in an instant!

Moreover, cement can also be used to build roads, or build houses, City walls, etc., are simply perfect building materials!

Looking forward to the future of the Qin Dynasty, Ying Zheng was full of energy.

He immediately ordered:"Everyone from the Xuanmo family comes over. I have important matters to discuss with them."

Three Kingdoms Period.

Cao Cao looked at the video played on the light screen and fell into deep thought.

"cement..."

"Is this thing really so useful?"

If it is as introduced, using cement to build the city wall, wouldn't it be twice the result with half the effort! Not only are the raw materials easy to find, the cement is made well, and the city wall can be built by adding some stones.

The city wall is also very strong and cannot be invaded by water or fire!

Cao Cao couldn't help but think I was tempted,"If the city walls were all reinforced with cement, how could I be afraid of attacks from Liu Bei and Sun Quan?"

More importantly, cement can not only be used to build city walls. (To read Baoshuang novels, go to Feilu Novel Network!)

If you are building a house, you are not afraid of fire at all. 0..

Living in a house made of cement is much safer. the other side.

Liu Bei and Sun Quan also began to have people study the cement manufacturing process.

None of the three were far behind.

Sui Dynasty.

Emperor Yang Guang of Sui Dynasty was ecstatic.

He happened to be planning to build the Grand Canal, so Light Curtain sent the most suitable building materials!

"Come on, come on! Yang Guang shouted excitedly to everyone around him:"Immediately order people to make cement. I have decided to build the Grand Canal!""

"This is God's will!"

"Other emperors don't do this kind of good thing that will benefit the future, but I will do it!"

Yang Guang looked determined to win.

Many officials discouraged him from doing this, which would easily waste people and money.

But he insisted on his own opinion.[]

Ming Dynasty.

Zhu Di clicked his tongue in surprise.

He had been fighting for most of his life and was familiar with building materials.

After all, building walls and fortifications is also part of fighting a war.

"Great, if there is this kind of material, I will definitely get it!"Zhu Di did not doubt the light curtain. The manufacturing method is there.

Instead of doubting it, he will know the authenticity when he makes it. 3.3

"The Ministry of Industry received the order, and I ordered you to mine limestone, iron ore and coal mines, and also find a way to make a hammer crusher."

After Zhu Di's decree was issued, he was thinking about how to use the cement after getting it. It is necessary to strengthen the Great Wall first.

Then the Forbidden City will also be reinforced.

If the cement production is enough, the ground of the Forbidden City and even the entire capital will be reinforced, and then the ground of the capital will be strengthened. As the center, he slowly built roads in all directions.

If possible, he even wanted to follow the example of later generations and build all the rural areas in the Ming Dynasty into cement pavements!
