Otaku Engineer in Great Tang Dynasty

Afternoon.

Li Zexuan thought for a while, and then took the carriage to the workshop. He wanted Fu Bo to help, to see if he could make cement.

In the morning, Yan Lide said that glutinous rice mortar can be used as an adhesive 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. It is a very extravagant thing to think about building walls.

Therefore, 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 stuff?

Yan Lide and his son also gave Li Zexuan a rough budget in the morning. If Yanhuang Academy adopts all masonry structures in accordance with Li Zexuan’s original intention, the cost of light building materials would have to be more than 400,000 tons, which does not include labor and decoration costs. .

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, it is harder to fill it in a short period of time than to reach the sky, but Li Zexuan will definitely not give up at Yanhuang Academy.

After thinking about it, Li Zexuan decided to gather the wisdom of everyone to see if he could produce cement with better effect and lower cost.

So many of the protagonists in the novels, don’t you always like to make cement, perfume, and mirrors in ancient times? They can make it, why can't they make it?

Keke, although I am not a professional, I know the general formula myself. Tell Fober and let professional craftsmen 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~?"

Fubo 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~?"

Fubo reacted and asked.

"Yeah~! I have already designed the building and layout of the academy. The main material is masonry. This wine must use glutinous rice mortar. In the morning, Yan Shangshu helped us initially estimate the cost. At least more than 400,000 Guans were needed, so I I plan to make a cheap substitute for glutinous rice mortar."

"Four hundred thousand coins~?"

Fubo almost jumped up. From this cost budget alone, he could imagine the scale of the Yanhuang Academy to be built by Li Zexuan. He thought about it, and then clasped his fist:

"Since the young master has such confidence 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 his young master had so many new and weird things in his mind, they only needed to take photos of everything Li Zexuan said. If you explore the ideas described by Li Zexuan, you will surely be able to create it.

"Cement is finely ground and mixed with limestone, clay, and iron ore powder in proportion. I call this mixture 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 lower than you last time. The temperature of the glass 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 it hardens, it can be comparable to solid stone. It can be used to firm sand, stone and other materials. It is a hydraulic cementing material that is bonded together to form a solid stone-like body. "

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, which was about 1,400. Fifty degrees, while the melting point of iron is 1,538 degrees, and the firing temperature of glass is 1,300 degrees. With this important information, I believe that the development of cement will be smoother~www.ltnovel.com ~ As for, why didn't Li Zexuan simply recall the proportions of the various components of the cement and tell Fu Bo, you think he doesn't want it! The key is that the books he reads are not books specifically made of cement. How can people boringly write down the proportions of each component in the book? So he just wants to remember memories that he didn't have~!

"Yeah~! I've written it down, Master, don't worry, I will organize the most elite craftsmen in the workshop to start developing this cement! I think there should be news in the next few days~!"

Fubo nodded and got up to believe.

He felt a little fortunate in his heart 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 take care of Fu Bo~! 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~! Master, don't worry, the old man will arrange it~!"

"Also, the relocation plan of the workshop is still implemented, but you will delay for a while on the specific date. I will relocate after I have been busy with the academy recently. Fu Bo, you can go to Mei Village to enclose the land first~!"

Li Zexuan rubbed his temples with a headache, and tears when he said too much, there is not enough money~! 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.

Besides, he got married a while ago and did such a big show, 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~!"

Uncle Fu arched his hands quite understandingly and said.
