Afternoon.

Li Zexuan thought about it, and then took a carriage to the workshop, he wanted to ask Fu Bo to help see if he could make cement.

In the morning, Yan Lide said that glutinous rice mortar can be used as a binder between masonry, but the cost is very expensive, in this era, although the price is low, but glutinous rice as a grain that is three to four times more expensive than rice, if you use this thing to build a wall, it is a very luxurious thing to think about.

Therefore, the houses in the Tang Dynasty were basically wooden structures, and the only ones that could afford to use bricks and stones plus glutinous rice mortar were super-large buildings such as the imperial palace, Zhaoling and city walls.

Yan Lide and his son also made a rough cost budget for Li Zexuan in the morning, if Yanhuang Academy adopts all brick and stone structures according to Li Zexuan's original intention, the cost of building materials alone will be more than 400,000 yuan, which does not include labor and decoration costs.

This amount has far exceeded the cost budget that Li Zexuan made at that time, and the reason is that Li Zexuan does not have a fresh understanding of the current construction technology and construction cost. Now, with such a huge capital hole, it is even more difficult to fill it in a short period of time than to ascend to the sky, but Yanhuang Academy, Li Zexuan will definitely not give up.

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

There are so many protagonists in the crossing, don't they all like to make cement, perfume, and mirrors when they travel to ancient times~? They can build it, why can't they build it themselves?

Ahem, although I am not a professional, I know the general formula, tell Fuber, let the 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 to give them a little inspiration, if you are lucky, there should be no big problem.

"Fauber, I've got something in mind that I need you to take someone to study recently. But I only know the approximate ingredients, and 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 straight to the point.

"Young 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, which is very important, and I hope that Fu Bo can bring a group of skilled craftsmen to study it as soon as possible." ”

"Cement~? Instead of glutinous rice mortar~? Is the young master going to build a academy~? ”

Fauber reacted and asked.

"Hmm~! I have already designed the building and layout of the academy, the main material is brick and stone, this wine must use glutinous rice mortar, in the morning Yan Shangshu helped us to preliminarily estimate the cost, at least more than 400,000 yuan, so I plan to get a cheap alternative to glutinous rice mortar. ”

"400,000~?"

Fu Bo almost jumped, just from this cost budget, he could imagine how huge the scale of the Yanhuang Academy that Li Zexuan wanted to build, he thought about it, and then hugged his fists and said:

"Since the young master is so confident in this so-called "cement", then the young master, although you tell the old man about the ingredients, the workshop is now full of talents, I believe that as long as we know the general composition, we can try to make it~! ”

This scene reminded Fu Bo of the last time Li Zexuan asked them to study the formula for glass production, although he didn't know why his young master had so many new and strange things in his mind, but everything Li Zexuan said, as long as they explored according to Li Zexuan's ideas, they would definitely be able to create it.

"Cement is finely ground and mixed with limestone, clay and iron ore powder, a mixture I call raw meal. Then put it into the record for calcination, the general temperature is slightly lower than the temperature of smelting iron, but it is a little higher than the temperature when you burned the glass last time, and it should be possible to use the earthen kiln where the glass was burned before, and the product after calcination is called clinker. Finally, the clinker and gypsum are ground together and mixed in proportion, which is cement~!

After the fired cement is added with an appropriate amount of water, it will become a slurry, which can be hardened in the air and in the water, and after its hardening, it is comparable to a solid stone, and it can be used to firmly bond sand, stone and other materials together to form a solid stone-like hydraulic cementitious material. ”

On the way over, he kept using his perverted spiritual power to recall the cement firing temperature he had seen in the books of his previous life, which was about 1,450 degrees, while the melting point of iron was 1,538 degrees, and the firing temperature of glass was 1,300 degrees.

As for why Li Zexuan didn't just recall the proportions of each component of cement and tell Fu Bo, do you think he doesn't want to! The point is that the books he reads are not books that specialize in making cement, so how can people be bored to write about the proportions between the ingredients? So he just wants to remember the memories that he can't remember~!

"Hmm~! The old man wrote it down, the young master can rest assured, and after a while, the old man will organize the most elite craftsmen in the workshop to start developing this cement! I expect there should be news in the next few days~! ”

Fauber nodded, got up and said confidently.

He was a little glad in his heart, compared with the last time he developed glass, Li Zexuan gave more detailed information this time, and it would be much easier for them to really study it.

"Then please Fubo~! Remember, people who enter the kiln must wear a mask~! ”

Li Zexuan told him uneasily, he didn't want those craftsmen to get lung disease after a few years of work.

"Yes~! Young master, rest assured, the old decay will be arranged~! ”

"Also, the relocation plan of the workshop is still being implemented, but you delay the specific date for a while, and then relocate after I finish the things at hand after I am busy with the academy at hand, Fu Bo, you can go to Meicun to enclose the land first~!"

Li Zexuan rubbed his temples with a little headache, and said that it was all tears, and the money was not enough~! At this time, if you move to a new factory, you are really powerless. In case the cement can't be developed, he has to grit his teeth and take out four or five hundred thousand yuan, and his family doesn't have so much liquidity.

Besides, he got married a while ago and made such a big show, but it was all real money, but he didn't regret it~! This baby daughter-in-law deserves that grand wedding.

"Yes, young master~!"

Fauber arched his hand in understanding.
