Judging from Miao Yan¡¯s appearance, it is estimated that preparations will begin in December at the latest, and the road construction will begin in spring at the latest.
After Liu Mingqi returned home, the first thing he did was to start writing about the experiment he wanted to do.
It¡¯s not cement, it¡¯s triple soil.
Cement requires ultra-high temperatures to burn the raw materials into powder, which today's furnaces cannot reach.
Besides, cement is a great weapon as soon as it comes out. By relying on it to build roads, the empire¡¯s roads can not only extend in all directions, but also be durable, reducing a lot of transportation losses.
¡°It has an obvious role in fighting, quelling chaos, and developing trade in various places.
This can directly overturn ancient history.
So Liu Mingqi doesn¡¯t dare to take it out now, lest the princes in the court will doubt him again.
Let¡¯s just say it.
Miao Yan is very likely to be one of the deputy prime ministers after the prince succeeds to the throne. Such important ministers will definitely clear the way for the prince.
Liu Mingqi was fine just doing business, and he kept inventing shocking things that the people worshiped and recited. It would be strange if Miao Yan didn't crucify him!
Do you think Liu Mingqi would be creepy if she had to be watched by people like Miao Yan no matter what she did?
Therefore, being low-key is necessary.
As a time traveler, you don¡¯t have to be in the limelight for everything, just live a happy life.
Things like Sanhetu are more suitable for Liu Mingqi to put forward opinions on the reconstruction of Yujie Road.
In fact, the official roads of Qin Zhidao and Dakang Dynasty used mixed soil, not necessarily Sanhe soil, but the effect is no worse than Sanhe soil.
Better Sanhetu can last three to five hundred years, but Qin Zhidao lasted nearly two thousand years, which is a miracle.
The official method of using soil, various ingredients, manual process requirements, etc. are all recorded.
Liu Mingqi now wants to use the Sanhe soil he knows and mix it with the mixed soil method of the Dakang Dynasty to see if it can achieve better results.
As the name suggests, Sanhe soil is soil composed of three materials. The best ones are lime, clay and fine sand.
If you are particular about it, add a certain amount of glutinous rice juice or brown sugar to it.
The earth buildings in ancient Fujian were built extremely solidly and will not be destroyed for thousands of years.
Many people say that when they built it, they not only used Sanhe soil, but also mixed it with brown sugar, egg white and glutinous rice, so it had such an effect.
And there is also a Hakka proverb of "a bowl of pork for a bowl of Sanhe soil".
But this is probably a misinformation.
Fujian is inherently mountainous, and there is never enough food. Otherwise, there wouldn¡¯t be so many Fujian people going to Southeast Asia and leaving their homes to struggle for life.
¡°You can¡¯t even eat enough, but you can still use a lot of precious resources like egg whites and glutinous rice to build earth buildings?
You must know that there are not two earth buildings in Fujian. There are more than 20,000 earth buildings in Yongding alone. How much egg whites and glutinous rice will be consumed in total?
Brown sugar is still a possibility. After all, Fujian is a famous sugar cane planting area and produces a large amount of sugar cane.
It is more feasible and reasonable to boil cheap sugar cane into brown sugar to increase the viscosity of Sanhe soil.
Let¡¯s use another example.
Is Zhu Chongba rich? Is there anyone?
But he still borrowed money from Shen Wansan to use glutinous rice and tung oil to increase the strength of the Jinling city wall so that the city wall could stand for hundreds of years.
But in the Ming Dynasty, there was only one city like this, and even after Zhu Di moved the capital to Yanjing, no more were built.
The reason is that building the city wall in this way was too expensive, and even the emperor felt that he could not afford it.
Let¡¯s not talk about earth buildings.
Although this statement is wrong, the three materials of egg white, glutinous rice and brown sugar combined with Sanhe soil can definitely greatly increase the solidity.
¡°Coupled with the tung oil used in the Ming city wall, Liu Mingqi can prepare even more materials.
But what is the best ratio is another science.
There are thousands of matching methods involved, so it¡¯s impossible not to study them carefully.
But Liu Mingqi also has a way to be lazy. Didn¡¯t he have a new apprentice recently?
After writing a rough plan, I called Wu Yeshuang over and asked her to serve as the "second tool of Liu's disciples". It was completely reasonable and reasonable!
¡¡
After two days of continuous fighting, Liu Mingqi finally managed toIt will be all right. "
"good."
Wu Yeshuang patted Liu Mingqi on the shoulder with satisfaction, "You are not bad, you are willing to spend money to make these useless things."
¡° If Wu Yeshuang did it alone, he might not have any results for three to five months.
But if you ask her to lead a group of people to do it without financial and material restrictions, and dozens of groups start testing at the same time, the speed will definitely be accelerated countless times.
So in this aspect, it is good to have money, and it is even better to not be stingy with spending money.
"Whether it is useful or not depends on how you think about it." Liu Mingqi said, "What if it comes in handy one day?"
Wu Yeshuang smiled, obviously thinking Liu Mingqi was joking.
Hot air balloons are a boring thing.
Sanhe soil is still somewhat practical, but if you make a Sanhe soil that can build roads, what's the use?
"Could you use these to build a fortress and live in it?"
If a clan member dares to do this, he will definitely be impeached by the censor.
She feels that Liu Mingqi is a young man with a wild imagination. He likes to invent all kinds of things when he has money, so that he can use his genius as much as possible.
¡°As everyone knows, what Liu Mingqi said is that with the foundation of Sanhe soil, it will be much easier to make cement in the next step.
The difference between cement and Sanhe soil is not very big.
By the way, for cement, do I need to modify the steel-making furnace? (Remember the website address: www.hlnovel.com
