If you don't pursue high quality, cement is actually very simple to make.
But there is another problem: how to crush those ore materials... Think about it at this time, if you rely solely on manual labor to crush the materials, the efficiency will be really impressive.
Fortunately, the hydraulic bellows has been built a long time ago, and now it only needs to be modified to crush materials. When the cement plant is built next to the Yellow River, the problem of power will not be a problem.
The strongest point of cement is actually after it is mixed with gravel and turned into concrete.
Think about the scene when reinforced concrete is poured into a modern building. It can be poured into any shape you want.
Whether it is rectangular, triangular or cylindrical, you only need to build a mold and put steel bars inside, and then any shape can be poured out, and it will be extremely strong after it is molded and dried.
In modern warfare, you can clearly feel the power of reinforced concrete by looking at the bridge decks that have been blasted with holes by artillery shells.
Ordinary red bricks are most useful for quickly building houses.
Coupled with the fire-resistant properties of red brick itself, building a house with it is not only fast and strong, but also can withstand fire to a certain extent.
After successfully making the cement, the next step is to experiment with the combination of red bricks and cement.
Several plasterers who are good at construction quickly learned to lay one layer of cement and one layer of bricks upwards under Lu Yan's explanation and personal demonstration.
Under the astonished eyes of everyone, the four masons only spent half an hour to build a wall that was as tall as one person and more than one foot wide.
The key is that the speed is high and the quality is excellent, which makes everyone present feel a little excited.
"With cement and red bricks, it will be much faster to build a house in the future!"
Geng Liang felt a lot of emotion. It seemed that he was quite resentful about building a house.
There is no way. Today's general supervisor is a steel mill, a shipyard, and now a cement factory is coming. The demand for these craftsmen is really too great.
After the craftsmen came to Chenliu, their families needed a place to stay.
In the past, traditional wooden houses were built. Not only was the construction time-consuming and labor-intensive, but the quality was not necessarily good.
Now that cement and red bricks are available, won’t building a house in the future be just a matter of sprinkling water?
Zhuge Liang also thought of using cement to strengthen city walls; Liu Bei thought of using cement to build roads.
It has to be said that the wisdom of the people is infinite. Lu Yan did not need to remind him too much, as they had already discovered most of the functions of cement.
But after all, they missed a function that can be called a plug-in level, and that is "building a city!"
To be precise, it was building a city wall.
With a steelmaking plant that produces 100,000 kilograms of steel per day, there will be no shortage of steel bars in the next two years.
When building a city wall, after setting up a mold for a section of the city wall and then pouring it with concrete, the efficiency is simply incredible!
As long as there are enough materials, a strong city can be built from the ground in half a month.
When smooth and solid cities suddenly sprout up one after another on the grassland, those grassland people will probably be scared to death.
...
"Brother Xuande." Lu Yan suddenly shouted to Liu Bei who was squatting on the ground and carefully observing the wall.
Liu Bei stood up, ran to Lu Yan in small steps, cupped his hands and said, "Sir, what are your orders?"
"The construction of the cement plant will be left to you. Whether you supervise it personally or assign personnel, I only have two requirements, efficiency! Confidentiality!"
Liu Bei's face became solemn, he bowed and said: "For such an important matter, I will personally supervise the responsibility. If there is anything wrong, I will come to see you!"
After all, he was once a warrior. After receiving the important task assigned by Lu Yan, Liu Bei issued a military order without even thinking.
Lu Yan looked around and said to everyone present: "Cement is top secret, and its level of confidentiality is not as high as that of battleships and artillery. Anyone who leaks the secret will be severely punished!"
The craftsmen have long been accustomed to all kinds of top-secret information. They basically never leave the area of the general prison, so confidentiality is fairly good.
Lu Yan mainly warned the officials. If they were not protected, some of them would be corrupted by money or beauty because of their unstable thoughts.
"I obey!" Liu Bei, Zhuge Liang, Geng Liang and other officials and minor officials all saluted solemnly.
After the cement experiment came to an end, Lu Yan, Liu Bei, and Zhuge Liang left to serve as prison guards.
When they reached the empty official road, Lu Yan suddenly reined in his horse and stopped.
When Liu Bei and Zhuge Liang saw this, they also stopped.
At this time, Lu Yan suddenly said to Liu Bei: "Xuande, after you build the cement plant, store as much cement, steel bars and sand and gravel as possible. Don't leak cement-related matters to anyone for the time being."
When Zhuge Liang heard this, his eyes flashed, as if he had thought of something!
Liu Bei asked doubtfully, "Why don't we take it out immediately and use it?"
With such a good thing, why not use it immediately to pave roads, build bridges, and build houses?
Lu Yan pointed to the northeast and said: "I want to lay roads in western Liaoning, and I want to build three strong cities in western Liaoning, so I need enough raw materials!"
"!!!"
After hearing Lu Yan's "ambition", Liu Bei slowly widened his eyes, and Zhuge Liang also opened his mouth slightly.
"Sir... do you want..." Zhuge Liang asked in a low voice.
"That's right!" Lu Yan grinned and said proudly: "After Liaoxi, there will be Liaodong, and after Liaodong, there will be three Koreas and Goguryeo! I will also take over all the grassland, and I will make the north the territory of my great Han Dynasty.
I want to eliminate the future troubles of the grassland forever!"
Zhuge Liang and Liu Bei were frightened by Lu Yan's "crazy" idea.
But now that we have cement, building roads and cities in the grassland is not such a far-fetched dream.
The two of them were infected by Lu Yan's arrogance. At this moment, there seemed to be a blockage in their chests, and they had the urge to look up to the sky and roar to relieve themselves.
Lu Yan saw that the two of them were feeling a little uncomfortable, so he couldn't help but smile and said: "It's easy to say it, but it's very difficult to actually do it."
After Zhuge Liang and Liu Bei were poured cold water on them by Lu Yan, the burning fire in their chests became slightly smaller.
"But no matter what difficulties and obstacles there are ahead, we have to do this...So Brother Xuande, stock up as much cement, steel bars, sand and gravel as you have for me!"
Liu Bei was so excited that he clasped his fists and performed military etiquette and said: "I will fight to the death to complete the mission!"
Lu Yan nodded, then turned to Zhuge Liang and said: "Kong Ming, please arrange manpower in the shipyard as soon as possible to liberate yourself from the tedious work. Lao Geng is not young and is not in good health. I am afraid that he will not be able to serve as a prisoner."
It's been too long and I need you to take over."
Jiang Zuo Jian was established and developed by Lu Yan on his own. It is the core and most precious asset to Lu Yan.
Liu Bei heard that Lu Yan actually wanted to hand over the supervision to Zhuge Liang.
I immediately understood,
Lu Yan, this is going to train Zhuge Liang as his successor!
