Chapter 261 Prefabricated Panels
A short and stocky man with a thick beard bowed and saluted him. "I am Xu Kang, the Shishi Commander. I am here to greet you, Your Majesty!"
Then, he asked Xu Kang, "Where is the finished cement?"
He decided to directly guide Feng Quji and other ministers to see the results, which would interfere with the normal operation of productivity.
"Xu Kang, kneel down. Your Majesty, please follow me."
Following Xu Kang's guidance, Feng Quji and the others entered the shed with confusion on their faces. The shelves inside were piled with layers of woven bags.
A bag was opened, and the powdered material inside was poured onto the ground. The court judge Yao Jia came to examine it. "Is this the cement that Your Majesty mentioned? I think it looks like some kind of lime paste."
Xiang Jia said calmly: Do the materials used to build walls have to be so fine? It's like the wind blows it up, and it's diluted like the cosmetics that women like to put on. Will it work?
"Ointment"? After thinking about it, Fuzhusi understood what Xiang Jia meant.
The paste used for bonding bricks and stones was invented in the Western Zhou Dynasty. It is simply a fusion of multiple materials, rather than a firing process.
However, Fuzhusi did not want to explain more, but asked Xu Kang to demonstrate how to use it.
Several soldiers came forward, mixed the sand, slag and mud, and put them into the mixing pool after adding a full bucket of water.
Xu Kang first apologized to everyone present, then lifted the edge and sleeves of his robe, held a shovel, and began the mixing process.
Pouring so much water made the consistency uneven, like thin rice soup. Seeing Xu Kang stirring the mud on the spot, Meng Tian couldn't help but grit his teeth slightly, but out of trust in Fu Chongsi, he didn't say much.
On the other hand, when the cement is ready, a craftsman brings a template that has been prepared in advance.
This mold is a square made of wood, one zhang long (about 3 meters), one chi high (about 0.3 meters) and three chi wide (about 0.9 meters), and is used for the design of precast panels.
They put thick concrete into the mold, and then put bamboo strips as thick as two fingers (about 5 cm) in. In this era, the so-called "steel" is unimaginable; however, bamboo is an unlimited and easy-to-obtain resource.
After laying a layer of bamboo strips and stones, concrete is added on top again, and then this step is repeated many times until the spaces in the three-foot-long and nine-foot-high square template are filled. Then a scraper is used to complete the final treatment on the surface to allow the cement to begin to solidify.
Zhang Fubu thought about it and considered that cement usually needs a whole day to complete the solidification process from moist to dry, and he did not have enough time here to wait for the process to end.
So Zhang Fusi whispered to Li Cheng and asked him to go straight to the back and get out a prefabricated board.
Soon after Li Cheng politely promised and set off with several armed men, he returned to the scene with a large prefabricated board.
Ding dong!
The sound of the prefabricated panels falling to the ground was dull and low.
Fuzhusi and others gathered around to discuss. Dianke touched the concrete floor with his foot and took a breath: "Is this the finished work? It's so strong... It makes me sad..."
It's really exaggerated. Are all the old masters of Daqin so "rough and unruly"? Fubusi stared at Dunlue with wide eyes, his mouth twitching constantly, as if he was about to explode.
Commander Meng Yi took a quick look and noticed the shark skin scabbard on Gongzi Gunpei's waist, which was inlaid with several gemstones, so he asked, "Can I borrow Zongzheng's sword?"
Don't you use your own...? Zongzheng Gongzi Gun rolled his eyes, covered the sword at his waist with his hands and stepped back: "This is a reward from the emperor, I won't lend it!"
Outside the wall, Meng Tian retracted his fingers, pulled out a ring-handled sword from Meng Yin's waist, and shouted, "Get out of my way!"
This passage describes the materials used by ancient people to build walls, including the processing methods of sand, lime and other building materials, as well as the production process of prefabricated panels, and incorporates certain fictional or simplified explanations. The era environment mentioned in the text and the details of the interactions between some characters may be fictional descriptions used to enhance the interesting reading in the context of historical knowledge.
"Clang!"
The cut made by the short weapon was deeply embedded in the prefabricated board, leaving a cut as thick as a thumb.
I hear the emperor complain about his "father" every day, but why is he being betrayed by his own "father" every day?
Fusu nodded slightly. The fact that the steel soldiers were able to cut out traces showed that the durability of these mixtures was indeed remarkable.
On the battlefield, those who are willing to damage their weapons in order to cut an inch of depth into the enemy's wall are usually regarded as "fools".
"What do you think about this matter?" Fusu asked.
Meng Tian returned the broken blade to Meng Ying and asked, "Your Majesty, can this item be damaged by water?"
Fusu shook his head and said, "That won't happen. Good concrete buildings are not afraid of water and fire erosion, and in the initial stage of solidification, water needs to be added continuously to make it stronger."
When pouring concrete, if the ambient temperature is high, the air is dry and cold, and the concrete is not cured in time, the water in the concrete will evaporate too quickly. This will cause part of the water in the gel to fail to fully hydrate and be unable to transform into stable crystals. The lack of sufficient bonding ability may cause flaking or powdery shedding on the surface.
Meng Tian and Qin Yue looked at each other and saw the same doubts in each other's eyes:
"In the past, Wang Ben, the Marquis of Tongwu of Wei, had been attacking Liangdu for a long time but failed to take it. Therefore, he used the tactic of using water instead of weapons to flood Liangdu and destroyed Wei in one battle." This is because although the walls of Daliang were strong, they were made of mud and would collapse once soaked.
But if the walls of Daliang were built with concrete instead of mud, perhaps even "Marquis Tongwu" would be helpless!
Qin Yue walked forward, and after finishing his greetings, he said, "No wonder your Majesty's new fiefdom is named 'Golden City'. The city walls built with cement are as solid as a copper wall and an iron wall!"
First he nodded in confirmation, then denied it: "However, although cement has advantages, it also has a disadvantage - when the temperature drops to 5 degrees Celsius... when winter comes, the cement stops solidifying."
Therefore, it is impossible to build a cement Jincheng County in winter. "It can only be implemented after next spring."
"The concrete currently being produced here has two uses. One is to be used to build dormitories for workers in places like the Longyi Coal Mine. Of course, the employees in the industrial zone here also have such living arrangements. We will inspect them together at the end of the meeting."
When Feng Quji and others responded respectfully, Fusu continued to explain: "Another allocation is to be sent to the Hedong Salt Fields for the construction of water dikes to isolate the surrounding water resources and prevent the impact on the salt lake."
After Fusu finished speaking, he signaled to Sima Chang and followed him to the workers' dormitory.
The rest area was built according to the structure of a military camp.
Every ten rooms share one public toilet, which is separated by a road for men and women.
The roof of the dormitory is built in a dome shape using tiles and rafters. This design can not only maintain the cool temperature indoors, but also effectively prevent rainwater from penetrating.
For the engineers, the dormitory was built specifically for them. The workers who moved from the Lishan construction site lived in this large-scale public dormitory, with each room accommodating ten people.
Since there is no shortage of coal supplies around the industrial zone, Yang Shu's design included one consideration: large rooms arranged in this way can provide heating like geothermal heating, which can at least allow employees to have a warm and good night's sleep.
So when they arrived, what they saw was a scene even more lively than the production workshop.
Compared with the high-temperature production of steel and cement, dormitory construction is closer to real life.
Jiang Jie walked to the front, picked up a dirty prefabricated component, and examined it carefully.
Compared to the mud blocks or brick-making techniques he had come into contact with before, this piece of material with gray texture was slightly thinner. Jiang Jie tapped it lightly on the ground twice and found that its hardness seemed to exceed that of ordinary building materials.
Sima Chang took the initiative to explain: "This is your majesty's new invention, called 'cement brick', which is mainly made of basic materials such as coal ash and waste, and cement is added as a solidifying material. It can be formed into a new type of modern brick building supplies without high temperature firing."
Lei Zhen smiled and did not respond immediately. At the time point of 210 BC, there were no mandatory environmental protection measures.
But as one of the messengers through the modern world, he always hopes to leave a piece of green water and green mountains for the future and keep the environment beautiful. For example, cement bricks are lighter and harder than traditional fired bricks, which reduces the pollution of smoke and dust produced by fired bricks to the environment.
Of course, the only drawback is that the cement mortar used for filling the joints may cause cracks in the wall more easily than traditional pasting, but these are only details and do not constitute a significant impact in such an early era.
In the current era of 210 BC, it is rare to have a brick house to live in, and the question of whether the building's appearance is beautiful is no longer critical.
More importantly, using brick-concrete structures to replace the current traditional wooden structures will not only make the buildings more stable and have better thermal insulation performance, but will also preserve the forest in the Guanzhong area and protect many giant trees with a diameter of more than several people hugging them.
This will not only reduce the sediment load in the lower reaches of the Yellow River, but is also crucial for the country's future resource storage as it moves towards a "maritime power strategy."
The promotion of honeycomb briquettes as a new energy carrier is also based on similar intentions.
It was amazing to see the workers holding whips and guiding hundreds of prisoners to arrange and fill the building materials in an orderly manner. The wall was built up quickly.
Before long, the outer walls of a group of dormitories were basically completed.
Next, they just need to wait for the cement to dry, and then use the cable rope to lift and assemble the floor slabs to complete the roof capping process. "Oh my God... so fast..." Jiang Jie muttered to himself.
