Back to Ming Dynasty as Zhu Biao

Chapter 221

The side door of the National Academy of Scholars opened slowly, and the science and technology officer inside held a dark object, threw it out of the yard, and scolded: "This thing is not as good as a piece of scrap iron, and it needs to be re-smelted."

After the people inside the door finished cursing, they raised their eyes to see Zhu Biao coming in through the arched door, his face turned pale, and then he came out and said, "Your Majesty Li Yan, I have seen His Royal Highness the Crown Prince."

"If you have any problems, go back and calcine them immediately. Only after a lot of refining can you become strong. Those new academicians, you should give more attention and less criticism."

"I've made a note." Li Yan's eyes flashed apologetically, and he said to Zhu Biao, "I'll tell Academician He right away."

"Don't be disturbed, you are busy with your work, just take a look at the progress of the grain seeds used for spring plowing this year." Zhu Biao waved his hand: "Academician Li, please invite He Qing and the others to the lobby, and let some who are good at stone also come over."

Zhu Biao took out a sheet from his cuff about some material plans for road construction and handed it to Li Yan.

Li Yan took it with both hands respectfully, and said with a smile to Zhu Biao: "His Royal Highness has offended us, and His Highness looks up to him, where did he come from as an academician?"

There are many noble people in this world, some are invincible because of their majesty, some are inherently elegant and cannot be insulted, and some are noble because of their status.

For the science and technology officials of the Ming Dynasty, Zhu Biao is the crown prince, that is, he is aloof and inaccessible.

But he is kind and humble to the people of the National Academy of Scholars.Instead, these science and technology officials are fascinated by him, willing to work hard for him and do things for the court.

Although there are few grains, they are all carefully selected seeds. This year Zhu Biao plans to go to the north more, and it will only take time for Jiangnan to recover.

The north still needs a lot of thought.

Sanbao then went to invite people from the Ministry of Industry.

In the National Academy of Scholars, several people put forward different materials about Zhidao, Zhu Biao motioned them to talk one by one.

Li Yan was afraid that other people would steal the conversation, so he quickly said: "Limestone calcination will consume a lot of labor, money and other things. It is better to use green bricks for the pavement instead."

To obtain hydraulic lime, limestone containing clay must be used for firing, and it is ideal to be made of hydraulic lime and volcanic ash.

Briton J. Parker fired a kind of cement with marl, the appearance is brown, like the mixture of lime and volcanic ash in the ancient Roman era, named Roman cement.

It uses natural marl as raw material and is directly fired without ingredients. It has good hydraulic hardness and fast setting characteristics, and is especially suitable for projects in contact with water.

It's just that Zhu Biao doesn't think about Daming now, and wants to summarize some experience from Qin Zhidao.

The last time he passed through the Shaanxi area, the road surface was still barren of grass, very flat, and the effect of walking was doubled.

In the future, it will be connected with Fuzhou, including the Lingnan area, to find a way to open up straight roads, which will greatly shorten the time for the people and the deployment of troops by the imperial court.

Continuing to build straight roads is a long-term and huge project. Beiping, Shanxi, and Jiangnan will be built first, and then expanded.

Encourage people everywhere to build roads, and mobilize everyone to build roads in winter when they are free.

"Well, His Royal Highness, I think that although the blue bricks are strong, the process is complicated, and the amount of bricks produced cannot supply all the road construction." He Qing continued.

"How about using crushed stones, such as the crushed stones discarded from the ore?" asked the person next to him.

"The gravel has edges and corners, and there is no other stuff to fill it in. It is very painful for the common people to walk." The academician who is familiar with the ore mountain shook his head and rejected the proposal.

Gravel is not as easy to walk on as a smooth road.

"How about the bluestone?"

"Is the bluestone slab not allowed?" Jiang Huanhai, Minister of the Ministry of Industry, walked in and saluted Zhu Biao: "The next official, Minister of Industry, Jiang Huanhai, has seen His Royal Highness the Crown Prince."

"Jiang Shangshu sit." Zhu Biao asked Sanbao to give Jiang Huanhai a chair.

"Qingshi accumulates water, so many state capitals in Ming Dynasty have come down, and the officials think that bluestone is not as good as that." Jiang Shangshu blew on the tea foam, smacked his mouth after drinking, and said: "Grass is hard in texture, but it is picked from various places. The road is paved with stone slabs and stones, and horse-drawn carriages and pedestrians can pass through it. Even if it rains continuously, the rainwater will not accumulate on the stone surface, and the water will seep quickly.”

Suddenly a person stood up and said to Zhu Biao, "His Royal Highness, I am Zhao Zheng, a newly promoted academician. After years of research on ore mountains, I think hemp stone is feasible.

If it is a collection, we can calculate the size and mine it. Usually, we use fire to scald the stone and pour cold water on it to extract stones from the mountain.

Cracks will appear on the stone, and quarrying along the cracks is simple.It's just that I had a bold idea a few days ago, please allow your highness. "

"Zhao Zheng, tell me."

"His Royal Highness, there are many mountains in the north and south, and some barren mountains are useless, they are used to select stones."

"You can use red bricks." Someone suggested again: "You can try this red brick."

"Blue bricks are the best."

Everyone is arguing.

Zhu Biao shook his head: "Let's discuss this matter again."

The firing of this blue brick is far more complicated than that of red brick, and the technology of brick kiln is insufficient nowadays.

If the brick body is cooled naturally, it is difficult to obtain a uniform red brick.There is no cement in this day and age either.

Houses are built with exposed brick walls, if you use naturally fired red bricks to build.The durability of the pavement is very bad.

The firing of blue bricks is stricter than red bricks, and the performance of blue bricks is better than that of red bricks.

Compared with red bricks, the firing of green bricks requires multiple steps, which not only changes the color, but also changes the properties of the bricks, improving the hardness and strength of the green bricks.

The frost and weather resistance of blue bricks is better than that of red bricks. Red bricks are not resistant to frost. Once the temperature is too low, they will foam and easily shatter.

In the northern lands, the winter is severe and the temperature is higher in summer. The red bricks will not last long.

Road construction is a long-term and important task. Even if the construction is slow, it will not be made into tofu, and it will only waste money in vain.

"You and Jiang Shangshu have a good discussion, make a plan in conjunction with the north and the south, and calculate the approximate silver and road construction materials of each prefecture.

Mark the mountains, rivers, lakes, etc. in various places, and plan the route. I believe you can complete this matter.Daming's straight way is to run errands with everyone alone, and everyone will do it together. "

"Yes. His Royal Highness."

"Jiang Shangshu, encourage the people to actively participate when there is nothing to do in the slack season. Let the people help the straight road in front of their houses. Active farmers will be rewarded by the court."

"Yes, Your Highness." Jiang Huanhai said: "I will also send people to lobby rich gentry and landlords to donate money to build roads."

For road construction, Zhu Biao asked people to go to various places to survey first, understand and record the terrain, prepare for road construction, and consider terrain and disasters.

Not long after the carriage left the Academy of Scholars, several literati from the Guozijian stood up and watched Zhu Biao's carriage leave.

He snorted and said: "The group of rotten sweet potatoes and rotten bird eggs next door are knocking there all day long, and the fertilizer is also stinky. I should talk to the prime minister someday."

"Yes, if things go on like this, they will be favored by the Crown Prince and His Majesty, and we have to please the Crown Prince as well."

The two passed by the gate of the National Scholars Academy chattering, with their heads held high, but their eyes were glanced at the National Scholars Academy.

However, the gate of the National Academy of Scholars was closed, and the two left angrily.

　Ask for collection, ask for subscription, ask for recommendation.
