Guide to traveling through the Northern Song Dynasty

Chapter 11 This love can be turned into cement

Another month and a half passed. Luoyang Imperial College was on summer vacation, and Xie Yan was still doing cement preparation experiments.

The overall idea remains unchanged, but it is necessary to constantly adjust the structure of the cement kiln, constantly adjust the spatial proportions of each layer of fired materials, and constantly change the combination of correction raw materials, mineralizers and retardants.

There are many things added, such as gypsum, fluorite, slag, sandstone, coal gangue, iron ore, etc.

These things don’t all need to be thrown in, but are determined based on the local limestone and clay composition of the cement plant. Xie Yan couldn't test the specific ingredients, so he could only use a stupid method-continuous trial and error.

Even if he doesn't apply for a patent, Xie Yan is not afraid that his cement will be overtaken by others. Because the raw material composition varies from place to place, the auxiliary materials that need to be added will also change accordingly. The quality of his cement will always be the best!

Of course, you don’t need to make it so complicated and just add two or three basic auxiliary materials. The quality will definitely be better than Daming’s existing cement.

When licensing patents to others, Xie Yan can do the same and only provide basic processes and formulas.

If you want the advanced version, you have to pay extra. Invite Bachelor Xie to go to relevant factories to conduct experiments in person, and then add excipient formulas based on local raw material ingredients.

"Ms. Li, please give it a try." Xie Yan said with a smile.

For a down-and-out nobleman like Li Minqiu, he could just call him "Li Yuanwai", but Xie Yan kept calling him "Ms. Li". This made Li Minqiu happy, and often expressed his gratitude to Bachelor Xie for his reasonableness.

The original meaning of Yuanwai is to increase the number of officials. During the Tang and Song Dynasties, idle officials bought with money could all be called "Yuanwai + a certain position". Gradually, those rich and powerful gentry were uniformly called "Yuanwai" when they needed an honorific title.

The same goes for Xianggong. It was originally a respectful title for the prime minister, but now everyone can call him Xianggong.

The essence is the same as Mr. Zhang, Mr. Li, Mr. Wang, and Master Sun.

Li Minqiu personally picked up a hammer and walked towards two brick walls that had been left hanging for many days. One wall was built with Li's cement, and the other was built with Xie Yan's new cement.

"Bang bang bang!"

Li Minqiu picked up the hammer and smashed it.

The brick wall was not thick. After only three hammer blows, the wall built with Li's cement already had obvious cracks in the joints.

He hit the new cement wall again, hammering it down three times, and lay down close to observe carefully. There are also cracks, but they are more subtle.

Li Min asked for praise: "Good cement!"

Xie Yan said: "Please try the condensed stone over there again."

"Condensed stone" is what Ming people called concrete, and iron bars and various hard stones have been added to it. But it's just adding wrought iron bars, not extravagant enough to add steel bars.

Li Minqiu's arms were sore from swinging the hammer a few times. He asked two farmers to come over and hit two thin concrete pillars with the hammer.

After a hammering, the two concrete pillars were completely broken, leaving only the iron bars inside still connected.

But one of the cylinders was so pitted, especially where it had been repeatedly stressed, that it was even broken by the farmer's hammer.

On the other hand, after the other concrete pillar was forcibly broken, the pit where the force was applied was much shallower and less numerous. And it was hammered several times before it broke.

"It's amazing!"

Li Minqiu squatted there and observed carefully, marveling as he watched.

After a long while, he turned around and walked up to Xie Yan, bowed and said: "Scholar Xie is a scholar of heaven and earth. I admire you very much!"

Xie Yan smiled and said: "Thank you to Mr. Li for borrowing the land and craftsmen, and for helping me purchase a lot of test materials. Once I apply for the cement patent, I will authorize the Li family to use the patent for free for ten years."

Li Minqiu subconsciously wanted to pretend to refuse, but was afraid of backfiring, so he immediately said goodbye: "Thank you, bachelor, and don't pay more rent. You can stay as long as you want in the future. Of course, this little rent can't repay the kindness of bachelor. From now on, thank you bachelor." I, the Li family of Luoyang, will never frown if I have an errand!"

"Easy to say." Xie Yan handed over his hand.

The next day, Xie Yan took the patent application materials and went to Luoyang Mansion Gong Cao's Patent Room.

Hearing that it was Bachelor Xie who had arrived, Gong Caoyu personally came to receive it and said to the patent examiner: "Pass the examination as soon as possible and don't waste Bachelor Xie's time."

After saying that, Gong Caoyu took Xie Yan to drink tea.

Before the cup of tea was finished, the patent examiner came over and whispered: "Master Xie, Master Xie has improved cement, and claims that the quality is far better than before. If steel bars and stones are added, it can even be used to build flood control dams. "

The reason why the existing cement in Ming Dynasty is difficult to use for building dams is not only insufficient in strength, but also insufficient in water resistance and corrosion resistance.

"puff!"

The worker took a sip of tea and quickly grabbed the patent application materials.

Luoyang Prefecture Gong Cao Peng is equivalent to the Director of Industry and Commerce of Luoyang City, the capital. Nowadays, an unspoken rule has been formed, and the positions of Gongcaobu are basically held by science scholars.

Xie Yan hid key information such as shaft kiln details and raw material ratios in the patent application materials. After reading the materials, Gong Caopu asked, "Is this true?"

Xie Yan replied: "If Tong Yushi doesn't believe it, you can go to the cement factory outside Li Yuanwai in the southern suburbs. There are brick walls made of new cement and poured concrete there."

Gong Caopu immediately said: "Thank you, bachelor, for leading the way."

"Leave now?" the patent examiner asked hurriedly.

Gong Caopu scolded: "The sooner the better. Do you know how useful this cement is? Since it can be used to build flood control dams, it can also be used to build castles on the border!"

The subtext is that although this was not invented by us, we were able to get our hands on it and report it quickly, which is definitely a great achievement.

Why are you standing there if you don’t want to take credit for it?

The Gongcao official immediately took the patent examiner and several of his subordinates and rushed to the southern suburbs.

After witnessing the performance of the new cement with their own eyes, the Gongcao people went back and forth quickly, immediately issued a patent certificate to Xie Yan, and then quickly reported it to the Luoyang prefect.

The Luoyang prefect reported the matter to the court.

…

The princess’s house.

Zhu Tangxi was painting in front of the lotus pond, which was in full bloom in recent days.

“Your Highness, Your Highness, Xie Liulang is here!” A maid ran to report.

Zhu Tangxi said happily: “Please come in quickly.”

Xie Yan was becoming more and more familiar with the layout of the princess’s house. Not only did he not need a guide to come in from the outer courtyard, but even the inner courtyard and gardens were just like going home.

He heard that the princess was by the lotus pond, so he walked a long way over.

Reading the error-free version! 6=9+Shu_bar published this novel for the first time.

Zhu Tangxi pretended to be serious and continued to paint the lotus. She seemed to be concentrating, but in fact her attention was completely distracted. The only thing in her mind was the footsteps getting closer and closer.

"Why are you free today?" Zhu Tangxi's tone was filled with resentment.

This little enemy was too ruthless. Since he gave her a necklace last time, he has not taken the initiative to come to her house for more than 40 days.

Zhu Tangxi was so angry that she stopped contacting him and waited for Xie Yan to come and apologize and coax her. In the end, after waiting for a long time, Zhu Tangxi couldn't stand it and took a carriage to visit Longmen Grottoes.

She insisted that she was going to Longmen Grottoes and passing by to see the progress of Xie Yan's experiment.

Every time Zhu Tangxi went to the southern suburbs, she was coaxed by a rustic love talk and went home happily to wait for the next time. Xie Yan didn't come after waiting for a long time, so she was so angry that she had to take the initiative to leave the city again.

After four visits, the Buddhas in Longmen Grottoes became familiar with her.

Xie Yan knew he was in the wrong, so he sat beside the princess and took her hand and said, "Sister, your lotus painting is so beautiful and lifelike."

Zhu Tangxi wanted to lose her temper, but she couldn't pull her hand back after pulling it twice, so she said angrily, "The first time you came, you wanted to cooperate with me to run a cement factory. The second time you came, you asked me to write a recommendation letter to the Ministry of Industry to check information. The third time you came, you asked me to help borrow a microscope. The fourth time you came, you went to the city to look for fluorite together. You are a person who does not go without benefits, what do you want this time?"

Xie Yan was stunned.

It seemed that as the princess said, he had a purpose every time he came. Scumbag!

This kind of thing must not be admitted. Xie Yan smiled and said, "Sister, you remember it very clearly. Have you recalled every time we met?"

"I don't have the time," Zhu Tangxi asked with contempt, "Tell me, what do you want this time?"

Xie Yan looked aggrieved: "Sister, do you really think I am such a utilitarian person?"

Zhu Tangxi asked back: "Aren't you?"

Xie Yan took out the cement patent certificate: "Sister, look at this?"

Zhu Tangxi glanced at the cover and said in surprise: "Cement is made?" Then he buried "I helped you all the way, but I found out later than the officials in Gong Cao."

"Isn't this a surprise for you?" Xie Yan got closer and closer, his mouth almost touching the princess's ear, "Look, sister, what is this cement called?"

Zhu Tangxi's ears were itchy from the heat, and her resentment had disappeared by a third. When she looked at the name of the invention patent, she instantly smiled: "You still have some conscience."

Xie Yan named this cement "Qin Cement."

This naturally came from Zhu Tangxi's title: the Grand Princess of Qin.

"In the future, the entire Ming Dynasty, and even the entire world, will use Qin Cement. Everyone who lives in a house built with Qin Cement will know that this is a gift from me to my sister," Xie Yan asked, "Do you like this gift, sister?"

"Yeah." Zhu Tangxi responded softly, her tone became particularly gentle, and she stared at the patent certificate again and again.

Qingluan, standing nearby, was also moved when she heard Xie Yan's words. This feeling and this intention spread all over the world, and it is truly known to the world. Alas, if I were a princess, why would no man treat me like this?

Zhu Tangxi put down the patent certificate and asked the maids to leave.

Then she said affectionately: "I have learned to make a kind of pastry. Can I make it for you today?"

"Okay." Xie Yan held the princess's hand and took the opportunity to kiss the back of her hand.

Zhu Tangxi did not resist, but peeked in the direction where the maids left. Seeing that there was no one around, she took the initiative to lower her head and kiss Xie Yan's face.

She wanted to kiss once and stop, but she made the man excited, and Xie Yan directly hugged her into his arms.

Zhu Tangxi felt hot all over, and her body softened a little, so she closed her eyes and let him hold her.

But the little enemy was not satisfied, and actually found her lips and kissed her.

The princess suddenly opened her eyes, resisted twice, and soon closed her eyes again.

Qingluan and several maids hid behind the rockery and peeked, whispering: "Kiss, kiss, it's so embarrassing in broad daylight!"
