[It is not difficult to say how cement is made. 】
[Please watch a short video below, you can easily learn it.] 】
The text disappears from the light curtain.
A short video takes its place.
"Cement is the second largest consumer on earth after water. "】
"It is a gray powder that is used to make concrete. "】
It is also used to lay bricks, build dams, or lay reservoirs. "】
"It is the glue that connects houses and buildings together, and this product has a long history. "】
["Cement has high strength, is relatively hard after condensation, and can effectively prevent fire and water. "】
"If you want to make it on a large scale, you need explosives and a kiln. "】
"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, and the other "540" needs to add pulverized coal to assist in 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 ratio can be adjusted according to the actual situation."] "】
["Limestone, also called limestone, is a common stone. "】
["Clay is commonly used in the production of porcelain, and is distributed in the country 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 meal, and then put it into a kiln and calcined it at a high temperature of thousands of degrees. "】
["The temperature of iron smelting in ancient times needed to reach 1500 degrees Celsius. "】
["The kiln used to make iron is used to calcine cement, which is not a problem. "】
["The third is to crush raw materials. "】
["After calcination, gypsum needs to be added and ground into a fine powder. "】
"A hammer crusher is needed here. "】
["Its structural design is as follows:"]
【...】
["But in ancient times, there was no electricity, and it was possible to replace electric power with water flow. "】
["If you overcome these three problems, you can make cement. "】
【......】
After reading it, the ancients let out an exclamation.
"The raw materials for making cement are so easy to obtain!"
"Yes, the big stones that are common in the mountains, the clay from which porcelain is fired, the stones from which iron is made, and the coal. "
"Is the cement made in this way really as easy to use as the light curtain says?"
"It's a pity that we don't have explosives, and if we want to mine the rocks on the mountain, I'm afraid we can't dig them by hand. "
"Alas, it can only rely on the imperial court. "
“......"
Qin Dynasty.
Ying Zheng stared intently at the video.
"Good, very good, the raw materials are so easy to obtain. "
"The black powder that happened to be made in recent times has no place to use it,"
"Let's just use it to blow up the mountain for the time being. "
"It's just that this hammer crusher, I'm afraid I want the Mo family to study it and make one as soon as possible. "
Ying Zheng has already thought about the great value of cement.
The Great Wall built today requires glutinous rice, which is very luxurious.
If you use cement instead, you can save a lot of food in an instant!
And cement can also be used to build roads, or to build houses, city walls, etc., it is simply the perfect building material!
Looking forward to the future of Daqin, Ying Zheng is full of energy.
He immediately ordered: "Everyone from the Xuanmo family is here, and the widow has important matters to discuss with them." "
Three Kingdoms period.
Cao Cao looked at the video playing in the light curtain and fell into deep thought.
"Cement..."
"Is this really so useful?"
If it is really the same as the introduction, wouldn't it be twice the result with half the effort to build the city wall with cement!!
Not only are the raw materials easy to find, but the cement can be made and the city walls can be repaired with some stones.
And the walls built are still very strong, and they are not invaded by fire and water!
Cao Cao couldn't help but be moved, "If the city wall is all reinforced with cement, I am still afraid that Liu Bei and Sun Quan will attack!"
What's more, cement can be used for more than just walls. (If you read a violent novel, go to Feilu Novel Network!)
If you build a house, you are not afraid of fire attack at all.
Living in a concrete house is a lot safer.
The other side.
Liu Bei and Sun Quan also began to let people study the manufacturing process of cement.
None of the three is far behind.
Sui Dynasty.
Emperor Yang Guang of the Sui Dynasty was ecstatic.
He was just about to build the Grand Canal, and the light curtain sent the most suitable building materials!
"Come on, come on!" Yang Guang shouted excitedly to the surroundings: "Immediately order someone to make cement, I have decided to build the Grand Canal!"
"This is providence!"
"This kind of good thing that benefits the future generations, other emperors don't do it, I will do it!"
Yang Guang has a posture of ambition.
Many officials discouraged him from doing this, as it was easy to work the people and lose money.
But he stood by his opinion. []
Ming dynasty.
Zhu Di was amazed.
He had been fighting wars for most of his life, and he was familiar with building materials.
After all, building walls and fortifications is also part of the war.
"Great, with this kind of material, I will get it!" Zhu Di did not doubt the light curtain, and the manufacturing method was placed there.
Instead of doubting, wait for yourself to make it 3.3 to know the truth or falsehood.
"The Ministry of Industry received the order, and I ordered you to mine limestone, iron ore and coal mines, and find another way to make a hammer crusher. "
After Zhu Di's will 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 was also reinforced.
If the cement production is sufficient, the ground of the Forbidden City and even the entire capital will be reinforced, and then the roads will be slowly built around the capital with the capital as the center.
If it were possible, he even wanted to emulate the afterlife.
The countryside of the Ming Dynasty was all built into cement pavement!
