Otaku Engineer in Great Tang Dynasty Chapter 451: Funds and cement~!
Afternoon.
Li Zexuan thought for a while, and then took the carriage to the workshop. He wanted Fober to help him to see if he could make cement.
Yan Lide said in the morning that glutinous rice mortar can be used as a binder between masonry and stone, but the cost is very expensive. In this era, although the price is low, glutinous rice is a kind of grain that is three to four times more expensive than rice. If you use this thing to build a wall, it is a very extravagant thing to think about.
So the houses in the Tang Dynasty were basically wooden structures, and the only super-large buildings that could afford masonry plus glutinous rice mortar were imperial palaces, Zhaoling Mausoleums and city walls. How could ordinary people afford this? thing?
Yan Lide and his son gave Li Zexuan a rough cost estimate in the morning. If Yanhuang Academy adopts Li Zexuan’s original intention and adopts all masonry structures, the cost of light building materials will have to be more than 400,000 Guans, excluding labor, And the cost of decoration.
This number has far exceeded the cost budget made by Li Zexuan at the time. The reason is that Li Zexuan does not have a fresh understanding of the current construction technology and construction costs. Now, with such a huge funding hole, filling it in a short period of time is harder than reaching the sky, but Li Zexuan will definitely not give up at Yanhuang Academy.
After much deliberation, Li Zexuan decided to gather the wisdom of everyone to see if he could make cement with better effect and lower cost.
So many of the protagonists in the novels, don’t you all like to make cement, perfume, and mirrors in ancient times? They can make it, why can't they make it?
Ahem, although I am not in this professional, I know the general formula myself, tell Fu Bo, let a professional craftsman study it! The glutinous rice mortar of this era is actually very close to modern cement (some modern scholars often call the ancient glutinous rice mortar "organic cement"). I believe it will give them some inspiration. If you are lucky, there should be no big problem.
"Fu Bo, I have thought of something that needs you to take the time to research it out recently. But I only know the general ingredients. As for the ratio between the ingredients, you still need to test it yourself~!"
When he came to the workshop, Li Zexuan went directly to Fu Bo's private "office" and said straightforwardly.
"Master, what is it~?"
Fauber asked curiously.
Li Zexuan said solemnly: "I call it cement. It is a construction adhesive used to replace glutinous rice mortar. It is very important. I hope that Fu Bo can bring a group of skilled craftsmen to hurry up and research it out. "
"Cement~? Instead of glutinous rice mortar~? Master is going to build a college~?"
Fuber reacted and asked.
"Well~! I have already designed the building and layout of the college. The main material is masonry. This wine must use glutinous rice mortar. In the morning, Yan Shangshu helped us estimate the cost initially. It needs at least 400,000 guan. , So I plan to make a cheap substitute for glutinous rice mortar."
"Four hundred thousand coins~?"
Fu Bo almost jumped up. From this cost budget alone, he can imagine how big the Yanhuang Academy is to be built by Li Zexuan. He thought about it, and then clasped his fist:
"Since the young master is so confident in this so-called "cement", even if you tell the old master the ingredients, the workshop is now full of talents. I believe that as long as we know the general ingredients, we can try to make it~!"
This scene reminded Fober the last time Li Zexuan asked them to study glass production formulas. Although he didn’t know why there were so many novel and weird things in his young master’s mind, everything Li Zexuan said, As long as they explore according to the ideas described by Li Zexuan, they will be able to make it.
"Cement is finely ground and mixed with limestone, clay, and iron ore powder in proportion. This mixture is called raw meal. Then it is put into the record for calcination. Generally, the temperature is slightly lower than that of smelting iron, but it is higher than yours. The temperature of the last time the glass was burned should be higher. The earth kiln used to burn the glass should be fine. The product after the calcination is called clinker. Finally, the clinker and gypsum are ground together and mixed in proportion. This is cement~ !
After adding proper amount of water, the fired cement will become a kind of slurry, which can harden in the air and in the water. After hardening, it can be compared to solid stone. Such materials are firmly bonded together to form a solid stone-like hydraulic cementing material. "
In order for Fu Bo and the others to research the cement as soon as possible, Li Zexuan also worked hard. On the way here, he kept using abnormal mental energy to recall the cement firing temperature he had seen in the books of previous lives. It was probably one One thousand four hundred and fifty degrees Celsius, while the melting point of iron is fifteen hundred and thirty-eight degrees Celsius, and the firing temperature of glass is one thousand three hundred degrees. With this important information, I believe that the development process of cement will be smoother~IndoMTL. com~ As for Li Zexuan, why didn't Li Zexuan simply recall the proportions of the cement components and tell Fu Bo, you think he doesn't want it! The key is that the books he reads are not books dedicated to making cement. How can people boringly write down the ratios of the ingredients in the books? So he just wants to remember memories that he didn't have~!
"Yeah~! I've written it down, Master, don’t worry, I’ll organize the most elite craftsmen in the workshop to start developing this cement! I think there should be news in the next few days~!"
Fuber nodded and got up to believe.
He feels somewhat fortunate that compared to the last time he developed glass, Li Zexuan gave more detailed information this time, and it would be a lot easier for them to study it.
"Then please come to Faber~! Remember, those who enter the earth kiln must wear a mask~!"
Li Zexuan warned with anxiety that he didn't want those craftsmen to get lung disease after several years of work.
"Yes~! Don't worry, Master, the old man will arrange it~!"
"Also, the relocation plan of the workshop is still being implemented, but you will delay for a while on the specific date. I will relocate after I have been busy with the college affairs recently. Fu Bo, you can go to Mei Village to enclose the land~ !"
Li Zexuan rubbed his temples with a headache, and tears when he said too much, and the money is not enough~! At this time, if we relocate to the new factory, it is really powerless. In case the cement cannot be developed, he will have to grit his teeth and take out four to five million sticks. His family does not have that much working capital.
Furthermore, he got married and engaged in such a big show a while ago, but it was all real money, but he doesn't regret it~! This baby daughter-in-law is worthy of that grand wedding.
"Yes, master~!"
Fu Uncle arched his hands quite understandingly and said.
