Red House Shoufu

Chapter 412 Tufa Cement Surprises the Holy Family

Cement is known as one of the greatest inventions of human beings. With it, both military and civilian construction will undergo earth-shaking changes. Lin Shu asked Lin Jiu to send the secret letter of the local method in his memory. Cement manufacturing technology is written out.

Of course, Lin Shu's memory is already a little fuzzy, but he only wrote down the general manufacturing method, and a lot of experiments are still needed.

However, with Dachu's current national strength, talents, and technical level, it is not a big problem to make simple cement.

Indigenous cement manufacturing is actually quite simple. The raw materials are clay bricks, fragments of various pottery vessels, fragments of various ceramic dishes, and various refractory materials, such as fragments of cylinders, basins, etc., and water-quenched slag (ironmaking slag). The waste slag in the furnace is directly put into the cold water pool for quenching), slag ash (residue after various coal burnts), each of the above materials can be taken alone at 70.00% V, or mixed together to get a total of 70.00% V.

Then take about 20.00% quicklime, and if possible, add plaster of paris, grind it finely from gypsum ore or waste gypsum model, heat it to 130 to 180 degrees in an iron pot and fry it until it is yellow-gray, and it is used to adjust the cement solidification speed. Use, but also do not add.

Then wash the above materials, dry them in a fire pit, and grind them into powder. They can be blended and ground together, or they can be ground separately and then mixed evenly. The most common stone can be used to grind them.

Mixing the above various finely ground materials together in proportion is cement, also known as mixed cement.

This kind of cement has good acid and alkali corrosion resistance, low early strength, and rapid strength growth under high temperature curing. It has strong water absorption and low heat release when used. It usually takes two to months to reach the standard strength. Its frost resistance is not as good as ordinary cement. , the curing period needs 20 days.

The master craftsmen of the Ministry of Industry and those enshrined by the royal family are all the most skilled people in Dachu.

The East Palace was brightly lit all night, and dozens of craftsmen were divided into several small teams and started experiments directly in the East Palace.

One of the biggest reasons why Lin Shu wanted to teach Gao Wancheng how to make cement was that the imperial court or the royal family could concentrate on major tasks and turn the theory into reality in the fastest time.

In the Hall of Qinzheng, the emperor had just finished processing the memorial on the dragon case. After Xia Shouzhong reported the abnormality of the East Palace, the holy driver went east and went straight to the gate of the East Palace.

"Your Majesty..."

Xia Shouzhong was as usual, and when he was about to shout that His Majesty was coming, the emperor had already seen piles of bonfires and circles of people in the courtyard of the East Palace.

He waved his hand to stop Xia Shouzhong's shouting and the kneeling of the guards at the gate of the East Palace. He walked into the yard and saw busy craftsmen beside piles of bonfires, and there were several small earthen kilns in the yard. There are a lot of earth and stones piled up.

The bellows whistled, and the craftsmen kept adding various raw materials to it, taking notes from time to time, and some even argued with other craftsmen.

The emperor recognized one of the older craftsmen, Shen Sinan, one of the royal enshrined, good at building cities, bridges, mausoleums...

The Dragon Head Palace was completed under the supervision of his father himself. Shen Sinan almost inherited all his father's skills, and just completed the construction of the Mausoleum of the Supreme Emperor last year.

"Master Shen, what are you doing?"

The emperor curiously approached Shen Sinan who was digging the kiln, and asked curiously, but he didn't expect that Shen Sinan was thinking about how to increase the temperature of the kiln, and he was extremely irritable.

Shen Sinan didn't turn his head back, and said irritably: "Don't bother me, I can't see what you do!"

"Bold, before Shengjia, how could you be so presumptuous!"

Xia Shouzhong's angry reprimand made the others stop what they were doing. When they looked at the emperor, their souls flew into the air, and they all knelt down on the ground in fright.

Only Shen Sinan was still immersed in his own world and couldn't extricate himself. He opened the earthen kiln that had been built, looked at the traces of calcination inside, and shook his head and sighed.

The little apprentice who was still his assistant boldly tugged at his clothes, after reminding him, Shen Sinan recovered his senses and looked up...

The disgraced Shen Sinan followed the emperor to the front hall of the East Palace, the kettle on the stove was humming, Gao Wancheng ordered the servant to bring hot water, and asked Shen Sinan to wash up briefly.

After the emperor read the secret letter sent by Lin Shu, the curiosity on his face gradually became extremely serious.

"Elder Shen thinks this method is really feasible?"

Shen Sinan cupped his hands and replied: "Return to Your Majesty, the minister and others have just made a furnace. Although it is not up to standard, but judging from Lin Hou's letter, it is feasible in all likelihood. But judging from the experience of the minister , this thing is made, and it needs to be matched with stones, steel and other things to build cities, dams, etc., otherwise, it will still be a castle in the air, and the foundation will not be stable."

"Oh?"

The original enthusiasm in the emperor's heart instantly cooled a lot, but Shen Sinan's subsequent words aroused his enthusiasm again.

I only heard Shen Sinan say: "However, I already have a method of improvement in my heart, and just now Marquis Lin sent me a method of forging steel, which coincides with my idea. After this cement is made, it can be used first. To lay official roads, or reinforce the city and dams. After the forged steel is completed, the reinforced concrete method proposed by Lin Hou will be used, and the river embankments will be able to withstand floods for a hundred years, let alone the city..."

"Speaking of the method of forging steel, I feel that there are still some problems with the method proposed by Marquis Lin. I feel that..."

"Furthermore, the reinforced concrete mentioned by Marquis Lin, in Yichen's opinion, is too expensive. I think you can try it with bamboo strips and other materials to see if it can be used for building a city. Speaking of this cement, I read it in Western Miscellaneous Notes. Arrived..."

For a craftsman like Shen Sinan, as long as he immerses himself in his own world, let alone the emperor sitting in front of him, no one can bring him back to reality unless the Great God Lu Ban appears.

The emperor could understand what Shen Sinan was saying at first, but after a while he couldn't understand what he was saying at all.Gao Wancheng also had a confused expression on his face, the father and son couldn't directly interrupt the enthusiasm of the master craftsman in the palace, they just looked at each other and raised the teacup to cover up their ignorance.

Fortunately, the experiment outside was still going on, and it happened that Shen Sinan's apprentice sent in the latest experimental results, which interrupted Shen Sinan's madness.

Only then did the emperor heave a sigh of relief, and signaled Shen Sinan to take care of himself, and sent the old priest out.

"Mr. Shen is good at everything, but when this madness comes up, it's a bit scary!"

"My son thinks so too..."

The father and son laughed heartily, and Xia Shouzhong, who was standing beside him, also laughed along with him.

Shen Sinan was frightening when he became crazy, but his skill was unquestionable.

Since Shen Sinan has already approved the methods of making cement, forging steel and reinforced concrete sent by Lin Shu, there is a high probability that this matter will be successful.

The emperor already understood why Gao Wancheng made the East Palace like a workshop, the important weapon of the country, so he should be cautious.At least for a short period of time, it must be ensured that this method will not be known to outsiders.

"After the craftsmen have perfected the manufacturing method, I will send them, together with all the materials, to the firearms workshop in the west of the city, and the six camps of the East Palace will also move there. What do you think, Father?"

"Then I will leave this matter to you. Let the internal treasury allocate money for my father. Don't embarrass the old Pixiu for the silver taels you need. You can't get a few taels of silver from him."

When Gao Wancheng thought of Wen Tongxuan's picky temper, he couldn't help but shudder.This old man is in charge of the household department, even if his father wants to repair the palace, he can't get a few taels of money, so he, the prince, should not run into a wall.

The emperor picked up the letter sent by Lin Shu and read it carefully again.Apart from the technical vocabulary, he also saw the importance of cement.

Lin Shu concluded several questions at the end, such as building roads first if you want to be rich, and water conservancy projects if you want to be stable, etc. Whether it is the construction of official roads or the renovation of water conservancy, cement is almost an indispensable thing.

Although the cost is high, compared with the silver spent on official roads and water conservancy maintenance, it is already much stronger.

"Lin Jinyu, the auspiciousness of the country!"

Hearing the emperor's evaluation of Lin Shu, Gao Wancheng recalled all the advice Lin Shu had submitted in the past few years, and couldn't help sighing: "Father is right, Master Lin is indeed the auspiciousness of the country!"

……

Lin Shu, known as the auspiciousness of the country, has entered a busy period since the winter moon.

On the eighth day of the winter month, after Lin Shu went to the Ministry of Officials to ask for leave, he began to write the wedding invitation himself.

In the past few years, he has been in the middle of the court like a fish in water. Although he has offended many people, he has more steadfast friends.

Several bigwigs from the cabinet are invited, as are several generals from the Fifth Army Commander's Mansion.It took Lin Shu a whole day to finally finish writing the invitation, which was done with Daiyu's help.

"The people from Gusu's hometown are about to arrive at Tongzhou Wharf. Bo'er is going to pick them up. Brother Shu, don't worry about the affairs of the house. The Ministry of Rites has sent many people to help. Don't neglect these people. , otherwise people will say that our Lin family has no rules..."

In the main hall, Lin Jin looked at the grandchildren sitting in the hall, and began to arrange work for them: "Brother Feng, you will send this invitation, especially the elders of the cabinet and the governors of the five armies. Generals, you must personally deliver it to the mansion. As for Brother Gui, you can't be idle either, go with your Seventh Brother."

"Bai's daughter-in-law, Feng's daughter-in-law, you two arrange for people to clean out all the guest courtyards in the mansion. The kang needs to be heated up, and the stove must be heated up. Put all the ornaments in the treasury on it, and don't let the clan After the people came, they felt that Brother Shu had deliberately neglected them."

"Yu'er, you are in charge of the kitchen these days!"

"what?"

Daiyu thought that her uncle would arrange some important affairs for her, but Lin Jin only arranged for her to be in charge of the kitchen.

Lin Jin smiled and said, "Don't think it's a trivial matter, take care of your brother's and sister-in-law's diet, and let them have hot meals and soups at any time, so that they can maintain their energy to handle outside affairs well."

When Daiyu heard it, it was true. Although Lin Jin didn't say it clearly, Daiyu still thought of it.

If something goes wrong in the kitchen, wouldn't the Lin family be taken over by someone?Wasn't his father, Lin Ruhai, poisoned in his food by taking advantage of the chaos?

An old family is like a treasure, and with Lin Jin around, the cohesion of the Lin family has almost reached its peak.Especially after several elders of the water generation and cousins ​​of the wood generation came to his hometown in Gusu again, Lin Jin detailed the errands again and performed their duties. The preparations have been properly arranged, and they are waiting for the arrival of the fifteenth day of the winter moon.

At noon on the [-]th, the Lin family specially gathered all the clansmen together and held a grand banquet in the main hall, which was regarded as a reward for everyone's busy days, and it was also Lin Jin's general mobilization for tomorrow's wedding.

Lin Shu was often drunk by his brothers at noon. After drinking a bowl of hangover soup, he was lying on the rocking chair under the sun with a foolish smile.

"Meow meow……"

thump!

After two meows, Lin Shu felt a heavy blow to his chest, and then heard the familiar purring sound.

Lin Shu rubbed Bai Jingjing's hairy head, and said with a smile, "Bai Jingjing, you are getting fatter and fatter, almost breaking my ribs!"

meow~
snort snort~
Bai Jingjing changed into a comfortable position, laying on Lin Shu's chest with her little paws in her arms, basking in the sun.

Lin Shu didn't know whether it was because he really drank too much or because of other reasons, he didn't care about Bai Jingjing's feelings at all, and talked to the cat by himself.

"Bai Jingjing, do you think I'm an old cow eating young grass? I'm almost 15 years old, and I want to marry a girl who is just over [-] years old. Tsk tsk, if I let go... I will be sentenced!"

"I'm going to the Wang family to marry my sister Yuan tomorrow. I'm quite nervous. What if my father-in-law suddenly repents? Do you think those people in the Wang family will kick me out with a big stick?"

"Sister Yuan is a good girl. When we first got married, I really didn't mean that I had any idea that she should marry her. To be honest, I was still thinking about who to marry at that time. At least Sister Yuan was familiar with her. At worst, three wives and four concubines will marry into the same yard in the future... Now that I think about it, my thoughts at that time were really naive!"

meow~
Bai Jingjing might have been disturbed, she opened her eyes slightly, and let out a dissatisfied meow.

Lin Shu thought it was responding to him, rubbed the cat's head, held Bai Jingjing's head in his hands and said to it: "Do you think so too? Ha, three wives and four concubines, I still feel that I have a heart of one person, and we can join hands It's the most comfortable way to go through this long life. Look at the concubine in the palace, what kind of fight for a man? I don't know if our emperor can control so many women, isn't he tired?"

"Master Lin, don't worry, I won't tell my father that you secretly spoke ill of him!"

"Teacher, I am the same!"

Lin Shu turned his head and saw that the speakers were the crown prince Gao Wancheng and the fifth prince Gao Wanxuan. He couldn't help but put his hands on his foreheads. It was really embarrassing to be arrested for speaking ill of his father.

He got up with the cat in his arms, and was about to salute but was supported by Gao Wancheng: "It's not in the hall, how can there be a teacher to salute your students."

"What the fourth brother said is correct, and I think so too!" Gao Wanxuan nodded and agreed.

Lin Shu said in his heart: "This little flatterer really knows how to flatter."

"The minister didn't say anything just now, even if His Highness went to complain to His Majesty, the minister would not admit it!"

Lin Shu's neck slacked, as if you would have nothing to do with me as long as I was shameless and refused to admit it, he made the brothers Gao Wancheng laugh.

Only Gao Wancheng said with a smile: "Master Lin is still interesting. I was in the Palace of Qinzheng just now, but I was often nagged by those old masters."

Lin Shu asked curiously: "Why, did something happen again?"

"Hey, Master Lin hasn't been to court for the past few days, and Wang Ziteng did something shocking..."

Gao Wancheng sighed, and explained to Lin Shu, "The Confucian family in Qufu was seized by Wang Ziteng. Wang Ziteng dispatched [-] troops from the Jiangnan camp, and temporarily put aside the action of destroying the White Lotus Sect. The Kong family surrounded them, and before the government could react, they detained all the descendants of Duke Yansheng's mansion..."
