Chapter 214 Cement is coming

This is poaching!

Chen Wanrong has always been the only one who can poach others' corners. Chen Wanrong has dug the Longwu Army, the Imperial College, and the county hall, but no one has dug him. He couldn't help but be stunned. The monks and his party not only poached the corners, but also came to his house and came to Zheng Qing's idea. Chen Wanrong was surprised.

Not only Chen Wanrong was surprised, but Ye Tianheng and the others never expected that the monk and his party would say this, and their eyes widened.

After all, it is not a matter of this. The emergence of a calendar is so difficult. It not only requires instruments to observe astronomical objects, but also requires a large amount of observation and master a large amount of first-hand information, but also has heavy and large amounts of mathematical calculations. Without enough mathematical talent and deep mathematical skills, don't even think about it.

The success of nuclear weapons has made the Chinese extremely proud. Success is not only due to the efforts of great scientists such as Qian Xuesen and Qian Sanqiang, but also the contributions of great mathematics like Hua Luogeng and others. If mathematicians such as Hua Luogeng and others did not conduct a large and heavy calculation, it would be impossible for the success of nuclear weapons to be possible.

Astronomical research, the birth of the calendar is the same. On the basis of mastering a large amount of first-hand information, there are also a lot of calculations that need to be processed by mathematicians. Moreover, the numbers calculated by astronomical are very large, and in our daily lives, we often call unimaginable numbers "astronomical numbers". This is the reason.

Just say one thing to know how big the astronomical number is. It is the home computer we are using now. If it is used for astronomical computing, it is likely to be dow, because the data is too large and you must use a supercomputer.

Even home computers could not meet the requirements of astronomical computing. In the Tang Dynasty, people could only use people to perform calculations. Just think about it, how big and complicated the project was. If someone with a deep mathematical foundation came to help, the birth of "Dayan Calendar" might have been ahead of schedule.

The Dayan Calendar in history was not compiled by monks and his ranks, but by later generations. The reason is that mathematical calculations cost a lot of effort. monks and his ranks only collected a large amount of first-hand information and completed the calculations. To do this, his mental energy was almost exhausted, and the work of compiling the calendar could only be left to future generations to do.

Of course, although Monk and his side did not finally compile the "Dayan Calendar", it did not damage his greatness!

The monk and his party knew that mathematical talent was hard to come by. Liang Lingzan had a good relationship with him. However, Liang Lingzan was an outstanding mechanic, not a mathematician, and could not help. He had always wanted to find a mathematical genius who could help, but he failed to do it. Now, when he saw Zheng Qing and knew Zheng Qing's achievements in mathematics, his heart rose and blurted out.

When studying astronomy with the monks and his party, he had the opportunity to ask monks and his party for mathematical problems. This was Zheng Qing's dream and he couldn't help but feel excited. However, Chen Wanrong had to make the decision and looked at Chen Wanrong involuntarily.

Seeing her joy, Chen Wanrong knew that she was moved and asked, "Isn't getting married?"

It was Zheng Qing's wish to marry Chen Wanrong and stay with Chen Wanrong for life. However, she is a talented woman with outstanding talents in mathematics. If a monk didn't show up, if she didn't have this opportunity, she would rather bury her talent and devote herself to taking care of her husband and children. With the opportunity to show her math talent, everyone will be moved and it is difficult to make a choice for the moment.

The monk and his party said a little embarrassedly: "Master Chen, I have to go after the calculations, and there are still a few years of hard work."

The meaning of this is to say that it will not prevent them from getting married and having children. Zheng Qing felt nervous and relaxed. Chen Wanrong smiled and said, "Master, if you promise me a condition, I will agree to my wife to help you."

If Zheng Qing, a talented woman with a deep mathematical foundation, would have compiled the calendar in advance, the monk and his party could not help but be moved and asked, "Master Chen, what's wrong?"

"Master, I have no other requests, only one thing, that is, when writing history books, I must write my wife's name!" Chen Wanrong's request was unexpected.

"The Dayan Calendar" is a milestone in the Chinese calendar. There is no reason for Zheng Qing to participate in this matter. Chen Wanrong will not stop her. On the contrary, she will support her and give her talents a place to display. However, if Zheng Qing's name is not known to future generations, it would be too sorry to her.

"Haha!" A laughter sounded.

The monk and his side smiled happily and said, "Master Chen, you should ask the historian this matter, not me. However, I can agree to this matter, and I will tell the historian."

"Thank you Master!" Chen Wanrong was also in a relaxed mood. Zheng Qing had a place to display her talent, but after observation, she would have to master a large amount of data, which would not hinder Chen Wanrong's good things. Maybe the children would be several years old by then.

"This trip is not false! This trip is not false! I have always wanted to ask everyone for help from numerical techniques, and I finally got what I want today! Amitabha, Buddha bless you!" The monk and his party clewed their high-highlights, very happy.

Chen Wanrong and the others heard him say things like "Amitabha" and "Blessed by the Buddha", and couldn't help but laugh happily.

Zheng Qing didn't care about anything else, moved a chair, sat next to the monks and his party, and began to ask about math questions, and planned to make scores, squared squares, and things were unknown. These professional terms came. The two of them discussed it in a word. Zheng Qing was no longer a delicate woman with bright eyes, heroic eyes, dancing eyebrows, and a talented man with an explosive talent.

This is something that Chen Wanrong has never seen since she met her. He couldn't help but stare at the boss, thinking that it would be right to let her participate in this matter. If she disagrees, her talent will be buried, which is a pity!

Burying Zheng Qing is burying the "Dayan Calendar". Burying the "Dayan Calendar" is a crime against history!

On the other hand, Monk and Hishang had his eyes as bright as the sun, and he was surprised. He knew that Zheng Qing had a wonderful understanding of Pythagorean theorem, but he did not expect that Zheng Qing had such a profound attainment in mathematics, especially Zheng Qing's memory of numbers, which reached a terrifying level. Monk and Hishang praised him for his vision from time to time.

The two of them were talking excitedly, and they found paper and pen calculations from time to time. This was a communication between geniuses. There were too many professional terms and too profound. Chen Wanrong and others were like listening to the heavenly book, and they didn't understand it at all. After listening for a while, they were no longer interested in listening to the two of them discussing issues and each asked someone to speak.

Chen Wanrong came to Liang Lingzan and said, "Master Liang, I have some ideas about machinery, so I would like to ask Master Liang for advice."

Telling Liang Lingzan about modern mechanical knowledge was the purpose of Chen Wanrong to take him to home tonight.

Liang Lingzan's achievements in machinery were unique in the world. It was difficult for anyone in the Tang Dynasty to surpass him. If you want to say that Chen Wanrong has a good idea in chemical engineering, he believes that! If you want to say that Chen Wanrong has some understanding of machinery, he really doesn't take it seriously and smiled and said, "Master Chen, please say it." Although he was kind, he didn't have much enthusiasm.

Chen Wanrong knew that he had a very high vision, so he didn't say much. He moved a chair, sat beside him, and began to explain the principles of modern machinery to him. If he didn't talk, he would have done it. After a while, Liang Lingzan found that he was wrong. Chen Wanrong's understanding of machinery was much better than he thought, and he could only prick up his ears and listen.

This lecture was amazing, and it continued until dinner. Even during the meal, Chen Wanrong still discussed mechanical issues with Liang Lingzan while eating and drinking. After dinner, he continued to talk and talked until the third update.

Liang Lingzan's talent in mechanical aspects is really amazing. Chen Wanrong said that he had not completely digested it, at least he understood it almost. In time, after he had completely digested it and the mechanics team matured, the machinery of the Tang Dynasty would make great progress!

Three days later, the furnace was built and cement production was finally ready.

Chen Wanrong got up very early, and with the help of Zheng Qing, he finished washing up and used it too early to test the production of cement. Cement is a major event, which is related to the national destiny of the Tang Dynasty and the future of China. Chen Wanrong was very excited. When he arrived at the workshop, he saw Sima Chengzhen, Ye Tianheng, Kou Yibing, Liu Huaide, Liang Lingzan, and the monk and his party had arrived long ago.

Looking up at the sky, the sun showed a little face. It was very early. Chen Wanrong thought it was early enough. Unexpectedly, they rushed to the front and asked curiously: "Why are you so early? You can't sleep in the military weapon surveillance again?"

"No! We thought you would come early, so we should come earlier!" Ye Tianheng's statement made Chen Wanrong laugh and cry, as if they were deliberately angry with Chen Wanrong.

"The prince is here!" A sharp voice sounded, and Chen Wanrong knew it was from Gao Lishi's mouth as soon as he heard it.

"I didn't tell the prince about the trial production of cement today. How did he know? Oh, there are two people in the military weapon surveillance. What else does he have to know?" Chen Wanrong thought to himself.

Everyone hurried to greet him. Li Longji strode over and waved from a distance, saying, "No, don't be rude. Chen Wanrong, you tried to produce cement today and didn't tell me, are you guilty?"

This is a joke, Chen Wanrong smiled and said, "Crown Prince, it's not that I don't report to the prince, but this is a trial delivery, and it may not be possible!" He looked at Princess Jinxian and Princess Yuzhen, and stopped talking, and everyone understood the meaning.

"I didn't sue you for a crime again!" Princess Yuzhen's boss was unhappy and pouted, "If you do this again, I will just say something bad next time."

Princess Jinxian covered her mouth with bare hands and couldn't stop laughing.

Li Longji smiled and said, "Chen Wanrong, don't compete with Yuzhen. Cement is so important. My father originally wanted to come, but there were too many things and couldn't get rid of it for a while, so he asked me to come and take a look."

With cement, the road problem can be solved. If the road is solved, the strength of the Western Regions Protectorate will suddenly increase. Will Dashi still dare to be so rampant? Defeating Dashi and establishing unparalleled achievements is the wish of Ruizong, and it is impossible to not pay attention to it.

"I'm just here to see you today. You can do whatever you should do and just pretend I didn't come." Li Longji was in a good mood.

He was easy-going in front of the good craftsman and had no airs. He did not have a stern face and looked arrogant when he saw the ministers. The good craftsmen did not regard him as an outsider. They responded and started to work hard.

"Chen Wanrong, do you really think I'm not here?" Li Longji called out Chen Wanrong, who was about to leave: "Take me everywhere. Cement told you so amazingly. I want to see how amazing it is!"

It’s not magical, it’s cement that’s amazing!

Chen Wanrong responded and said, "The prince is interested, so I will do it. Please move your way here. Let's go and see the ingredients first."

Li Longji didn't say much, followed Chen Wanrong to the ingredients room, and saw a grinder in the room grinding limestone. The production process of cement is not complicated. First, it is to polish the raw materials and mix them into raw materials. Then it is calcined into the clay material and then added gypsum to make it cement.

Grinding is the first process, which requires grinding limestone finely and mixing it with clay. Although the grinding machine designed by Ye Tianheng is simple and not efficient, it can still achieve its goal, which is very good.

After the limestone was polished, it turned into powder. Li Longji was very surprised: "This is Master Ye's masterpiece, right? It's so magical!"

"The prince is too awarded! Ye Tianheng's design is really embarrassing. Master Liang has a better design. It is estimated that the new machinery will be made in a short while. By then, there will be a leap in both efficiency and polishing!" Ye Tianheng came over with a crutch, looking ashamed: "I just discussed with Master Liang and realized how many defects there were. It would be great if Master Liang had come earlier!"

Liang Lingzan was originally a mechanical genius. He explained modern mechanical knowledge to Chen Wanrong, which made him undergo a major transformation and his mechanical understanding even more amazing. He discussed this grinding machine with Ye Tianheng just now and told him about the thirteen shortcomings in one breath, which made Ye Tianheng, who was originally very proud, feel ashamed.

"Master Liang, it seems that you will still be busy after you prepare the armillary sphere for the masters?" Li Longji laughed: "The more busy the good craftsmen of the Tang Dynasty are, the stronger the Tang Dynasty is! This is a good thing!"

"The prince is wise!" Everyone praised it in unison.

Li Longji waved his hand and said, "What should I do next?"

Chen Wanrong explained to him: "Prince, this grinding is for the ingredients. The limestone and clay are polished finely to match. Now, this is the first time I have made the ingredients. I don't know much about it. I have to wait until this time I have made it, and I will have a clear idea in my heart."

The ingredients are prepared according to the active ingredients of limestone and clay. If the iron trioxide is insufficient, iron ore powder must be added. If the silicon is insufficient, silicon must be added, which is called correction.

The first time I did not analyze the data, I could only cross the river by feeling the stones and try to find out.

"It's the first time I'm not familiar with the situation. It doesn't matter. There's a second time when you have the first time, and there's a third time. As long as you use your heart, it will be better every time." Li Longji gave many praises.

"Thank you Prince Jiameng." Chen Wanrong thanked him and then said, "When the ingredients are ready, add water to make the slurry."

"Why do you need to add water?" Li Longji was surprised.

Chen Wanrong explained: "Prince, you can do it without adding water, but the dust is very heavy and it will be too harmful to people. Therefore, adding water, although more carbon is used, it will not harm people."

Li Longji nodded and said, "So great! So good!"

There are dry and wet methods for cement production. If the dry method does not add water, the energy consumption is low. The main problem is that it is heavy dust, which is harmful to the human body. Chen Wanrong does not intend to use dry method to produce. Wet method can reduce dust and is good for the human body, because adding water will cause excessive energy consumption.

For the sake of human health, it's worth it!

Another advantage of wet production is that the components are evenly mixed, have good fluidity and have good cement quality.

Chen Wanrong looked at it and the ingredients were almost done and he could make ingredients. With a command, several strong men took action, added water to make slurry, and then put it into the rotary kiln.

The rotary kiln is a cylinder with a certain inclination. After the slurry is added, the hydraulic power will slowly turn. The craftsmen use carbon to raise the fire, and the flames will rise soon and start calcining.

Calcination is to get clinker and achieve partial melting. This is a slow process, only waiting. Time passes silently, everyone waits quietly, no one speaks.

Chen Wanrong was very anxious. Although the cement production process is not complicated and the technical difficulty is not high, this is the first production, and it is still unknown whether the cement needed can be produced.

The unknown is the most anxious!

"It would be great if there were such advanced observation instruments as modern society!" Chen Wanrong sighed in his heart, and suddenly remembered something: "When designing, why did he forget to ask Master Ye to open an observation hole?"

If there is an observation hole, whether it is good or not, you just need to look at it and you can tell it, which is much better than doing it here.

The equipment is simple and there is no testing method. I don’t know the composition of limestone and clay. Even if I have rich experience in cement production, I can’t use it. Apart from waiting, I still have to wait.

Looking at the sun, it was almost noon. Chen Wanrong thought it was almost time to stop. The craftsmen put out the fire and put the materials in the cooling warehouse to cool.

Chen Wanrong could only use natural cooling, which was another slow process. At noon, everyone knew that they were going to wait, but they had nothing to do, but they still rushed to wait for lunch.

Li Longji is no exception, but he is just calmer than others. Looking at Chen Wanrong who was a little anxious, Li Longji comforted: "Don't be anxious! Skills are the correct method obtained through hundreds of tests. If there is no failure, where can success come from! Even if this time is not successful, you can still do it after summarizing. Failure is not terrible, but the terrible thing is not to summarize. If you fail, summarize more, you will definitely make cement!"

The words made sense, but Chen Wanrong couldn't listen to it, and just responded casually.

Not only Chen Wanrong was anxious, but even Ye Tianheng and the others were anxious, but they just didn't say it out.

Finally cooled down, Chen Wanrong asked someone to take out some from the cooling chamber and look at it, shouting: "It's done! It's done! I thought I was going to go back to the furnace, but I didn't expect it. It was just right!"

The difference between raw materials and clinker was obvious, and Chen Wanrong could tell at a glance. Ye Tianheng and the others were overjoyed when they heard this: "It's really done! It's really done!" They heard Chen Wanrong talk about cement so amazingly that they had long wanted to see what cement was. Now, it's finally successful. Everyone can't suppress their joy and hug each other to celebrate.

Li Longji picked up a piece and asked, "How to use this?"

Chen Wanrong smiled and said, "Crown Prince, it can't be used yet, so I have to polish it once."

Cement production is summarized as "two grinding and one burning", which means that the ingredients must be ground fine before the preparation, and after the calcination is successful, it must also be ground fine. Burning means calcining.

If the clinker is not fine, it cannot be used.
