Rescue system: run away from the host, calm down

Chapter 307 Dungeon Construction 17
When everyone arrived at the depths of Daqing Mountain safely, the smoke from the cooking was billowing from a distance, and the wide tents were set up in a row, which was very spectacular.

What caught the eye was the orderly large-scale excavation construction site.

In the three-meter-wide trench, in the cold winter, the workers wore bunts, sweated profusely, with hoes and shovels, and all kinds of strange tools.

Dustpans, hanging baskets and baskets are filled with brownish-yellow soil, tied with slings, and there is a tall and upright pole on the ground, which is a simple elevator. The handle on the gear wheel is manually turned, and the two work together to load it. The loess in the frame gradually rose up with the shortened suspension rope, and then pulled to the distance with a cart.

The brown-yellow soil dug out was not discarded, but pulled to a brick kiln workshop.

In ancient times, there was no underground construction of concrete and steel structures, so only local materials could be used for research and development.

Therefore, bricks are an essential building material. A series of physical changes will occur when the clay tile embryos are fired and dried, and then fired in a high-temperature kiln.

She had never touched this piece in her previous life, so she could only grope a little bit based on the sporadic clues provided by the mall and the book knowledge she only remembered, such as the ratio, temperature, time, and perhaps any auxiliary materials needed.

She can also give a general idea, the change of mineral structure, formation of new mineral tissue layer, decomposition and combination, crystallization and diffusion, a series of fusion changes during the period, and finally become a product with a certain color, dense, hard, and high mechanical strength. These processes all need to be tested one by one.

In ancient times, there were blue-brick and tile-roofed houses, and the firing of bluestone and blue bricks had to go through several stages of moisture removal, heating, launching, and kiln opening.

Therefore, professional craftsmen have the most say in the firing of blue brick tiles and bricks, but some ancient technologies cannot meet her requirements, so it is necessary to combine reality and innovate.

The most difficult thing is not to burn bricks, but to develop cement.

Cement is mainly made of sandstone, silicate mineral iron powder, limestone and slag. When making it, these ingredients need to be mixed in proportion and then ground into a fine powder.

Limestone is definitely the biggest volume of raw material, cement production, mining the particle size [-], higher hardness, so the broken limestone crushing occupies a more important position in the cement material crushing.

These raw materials are not easy to find. The system collects or looks for alternative raw materials in Daxing Mountain. For example, there are many coal gangue hills, which can be used as an alternative. In addition, there is a natural advantage here, underground volcanic rock.

Pozzolanic composite materials are mineral raw materials with natural silica and alumina as the main components.It does not harden after being ground into fine powder and adding water, but it can not only harden in air but also continue to harden in water after being mixed with lime and mixed with water.

So pozzolanic cement is also a good choice.

However, cement grinding is the final process of cement manufacturing, and it is also the most difficult process. The most suitable strength for grinding cement is to form certain particles, accelerate the hydration speed and area, and meet the requirements of cement paste coagulation and hardening.

With the current means, there is no way to do it, but it is a matter of human effort, and if you study slowly, there is always a chance of success. If no one innovates, there will be no advanced technology in the future.

Besides, with her plug-in standing on the shoulders of giants, as long as she is guided correctly, I believe the craftsmen will get twice the result with half the effort.

These two workshops can be successfully put into research and development, thanks to Lin Yiqiu and his group. I didn't expect that each of them is hidden, and there are talents in various fields, such as firing bricks to make kilns, ramming earth to build walls, building houses and beams, and coal smelting. Burning charcoal, everything is refined.

When it comes to the firing and utilization of coal, Grandpa Hu is also an expert, so she built a third workshop for this purpose.

There is also a stove room for sprouting bean sprouts. The current soybeans and mung beans are purchased from the mall.

For everyone in this cold winter, supplement the indispensable vitamins and cellulose for the human body.

There are too many strange and good things, the captains are numb, no one is asking the source, and the team members who consciously keep their mouths shut, when someone asks, they reply, "Do you know how the cat died?"

The wise man quickly realized the reason why curiosity killed the cat.

Those who are stupid will receive the second sentence, "You should figure out this question first, and then ask other questions."

So after it spreads in private, people with bright eyes and bright hearts will remind: think about whose food is used now, if you don’t want to freeze to death in the ice and snow, work honestly.

There are also curious people who are unwilling to get the answer, jump up and down, and ask around, but soon, the food of this person is only half of the food of others, and those who make troubles can only go hungry. After struggling like this, no one dares to talk nonsense ,Of course, this is something.

Returning to the astonished Han Yi's face, he never expected that Miss Cheng really followed her word and started to build an underground project.

But freezing three feet does not happen in a day, and the construction of underground projects is not comparable to ordinary cities. He is also a person who has experienced it, and knows the difficulties.

Ordinary farm tools can be used in loess now, but once they reach the rock layer, these tools are useless.

However, the special tools used by ordinary well drillers simply cannot complete such a large amount of work, so this is a huge project that is time-consuming, labor-intensive and extremely difficult.

But aside from this point, the entire construction site, a large number of laborers are working in an orderly manner, continuing to work in an orderly manner, very similar to that.

After a little more observation, I also found a lot of unseen utensils and means of transportation, which were properly coordinated, and the half-built kiln house in the distance was explaining that the other party couldn't be more serious.

The shock in front of him made Han Yi unable to recover for a long time. Many facilities and operating methods may be higher than the dungeons they built before.

Even so, he disagreed, knowing that he had no intention of persuading him, so he had no choice but to turn his attention to Ye Ye.

Although Zhou Yanlan was startled in her thoughts, she only accepted the fact for a moment.

Turning to look at the person next to him, "Is there anything I can do for you?"

Cheng Xiaoxiao shook his head, "No, it's good, don't bother Master Yan."

Zhou Yanlan stared at the person in front of him for a long time, making sure that the other person was not evasive, and then slowly turned his head.

"I see that you are short of manpower here, why don't you send some manpower over here?"

"Don't, don't, that's too troublesome."

Knowing that his people are all over the place, and they will come here in a short time, what if there is a cold wave?
Let's forget it, the far water can't help the thirsty people, she is afraid that people will be broken in the middle, then she is not guilty.

"Yes, Miss Cheng, don't refuse. We have also built dungeons before, and those experienced masters are still there, and they will definitely be of great help."

Han Yi happily spoke up, and his master finally came to his senses.

Cheng Xiaoxiao was dumbfounded, how old is an experienced master?
