Han Xiang

Chapter 97 Soil Cement

From the end of the third year of Jian'an to the beginning of the fourth year of Jian'an, major events in the territory of the Han Dynasty continued, and they were basically related to Cao Cao.

Yangzhou Sun Ce defeated Danyang Zongshuai Zulang, and surrendered Liu Yao's general Tai Shici, completely holding Danyang County in his hands, leaving only Yuzhang in the entire Jiangdong;

Sun Ce listened to the suggestion of the school lieutenant Zhang Hong, and sent envoys to Xudu to pay tribute to make friends with Cao Cao;

Cao Cao was in the place where the Central Plains fought four wars, and he had no time to go to the south to attack Yuan Shu. Thinking of the principle that the enemy of an enemy is a friend, Cao Cao presented Sun Ce as a rebel general and enfeoffed as Marquis of Wu;
In order to contain Yuan Shu and appease Sun Ce, Cao Cao not only promoted Sun Ce to a higher official rank, but also married his younger brother and daughter with Sun Ce's younger brother Sun Kuang, and made Cao Zhang marry the daughter of Sun Ce's brother Sun Ben.

Liu Biao of Jingzhou formed an alliance with Yuan Shao to support Zhang Xiu against Cao Cao, and Cao Cao was unable to defeat Wancheng three times;
During the Zhengwan period, Huan Jie, a native of Linxiang, lobbied Zhang Xian, the prefect of Changsha, to oppose Liu Biao and kiss Cao Cao;

As soon as Zhang Xian heard that it was reasonable, he raised an incident in Changsha, and Lingling and Guiyang counties responded at the same time;
The rear of Jingzhou rebelled, and Liu Biao's support for Zhang Xiu weakened, which relieved Cao Cao's pressure in disguise.

Xuzhou Lu Bu was defeated and killed, so Cao Cao used his confidant Che Zhou as Xuzhou's governor, completely solving the threat from the southeast.

Gongsun Zan of Youzhou was defeated and set himself on fire in March of the fourth year of Jian'an. So far, Yuan Shao has unified Hebei and occupied the four prefectures of Ji, You, Bing, and Qing.

Among the princes, Cao Cao operated on multiple lines like an e-sports master, and Long Xiang, who was far away in Hefei, was not idle.

He started preparing soil cement in the fourth year of Jian'an, and in May he produced soil cement with satisfactory strength.

On the day when the experiment was completed, Long Xiang was in the temporary shed, jumping up and down happily like a child.

Because the main material of earth cement is the same as that of brick, it is planned to set up the cement factory in the kiln area.

Long Xiang has been busy with experiments recently, and Lu Su is taking care of Hefei's military administration. He himself adjusts ratios in the 'laboratory' every day, recording data while experimenting.

When Lu Su and Feng Zhong saw Long Xiang, they saw him covered in dust, with mud on his legs, face and hands, dirtier than the brick maker next to him.

Feng Zhong looked at Long Xiang and asked curiously: "You are in a hurry to find us, what's the matter?"

"That's right, a lot of refugees have flooded in recently. Most of the remaining houses in the city are seriously damaged and must be repaired before they can be used. General Feng and I are very busy."

Lu Su's implication is that if you are playing with your cement experiment, don't call us to accompany you.

Long Xiang grabbed a handful of gray powder, spread it in his hand and said excitedly to the two of them: "Uncle Zhong, Zijing, the cement I'm talking about is ready."

"Oh congratulations"

Feng Zhong answered very plainly. The craftsman camp under his command is full-time construction and is no stranger to cement-like adhesive materials.

The yellow mud used to build the granary last year was also good, so Feng Zhong didn't have strong expectations for the cement.

Lu Su was not interested in construction. Seeing that Long Xiang was so excited, he asked curiously, "Then what?"

"Naturally, a workshop will be built immediately for mass production, and it will soon be used for city defense and urban construction."

Long Xiang squeezed the soil and cement in his hand, his face was full of complacency that outsiders could not understand.

The formula of soil cement is very simple, but it must be close to the label of later generations. Without the aid of any scientific equipment, it can only be tried slowly through stupid methods. Except for those who are really interested in civil engineering, few people are willing to "play with mud" every day. Eat ashes'.

After hearing this, Lu Su quickly dissuaded him: "There are already many workshops in Hefei. I suggest slowing down the cement workshops. Too many are too easy to chew."

Feng Zhong couldn't bear to discourage Long Xiang's enthusiasm, so he patted Lu Su on the back and said, "It's okay to build a cement workshop, but my people really can't arrange it recently. How about waiting until the end of the year?"

Long Xiang was noncommittal, and quickly changed the subject and asked: "The houses in Hefei are too scattered, and repairing them is a waste of time. How many houses are still lacking for resettling the people?"

"Hundreds of rooms." Feng Zhong frowned.

Long Xiang waved his hand and said, "Then don't repair it, just build a new house directly. Anyway, there are a lot of bricks fired this year, and it is estimated that more than a hundred new houses will be no problem."

Feng Zhong opened his eyes wide and asked: "Aren't those bricks reserved for repairing the city walls? I heard that last year Cao Cao flooded Xiapi with water, causing serious damage to the city walls of Xiapi. Cao Cao."

Lu Su nodded and added: "The rammed earth city wall has been soaked in water for a long time, and there is a high possibility of partial collapse. It is easy for the enemy to take advantage of the damage. It may be better to replace it with green bricks."

Long Xiang said with a leisurely smile: "The conventional brick and wood structures now mostly use yellow mud as the bonding material, but the yellow mud is easily soluble in water, so of course it can't stop the water from soaking.

The cement I prepared is different. It is as hard as a stone after it is completely solidified and is not afraid of blisters. Therefore, even if bricks are used to strengthen the city wall, the cement workshop is still inseparable. "

Lu Su stretched out his hand in surprise, picked up a handful in Long Xiang's hand, and thought, isn't this just dust?

"It's so amazing."

Long Xiang turned around and went back to the experimental shed, and found two cement wastes from inside.

Handed it to Lu Su and said, "Zijing, try it yourself, and see what's the difference between this cement block and a stone?"

Lu Su caught it with both hands, and immediately felt some weight. He casually dropped it on the ground in front of him, and immediately made a hole in the mud.

"It really is"

"Hiss is so powerful, the cement workshop must be built, but build a new house?" Feng Zhong hesitated to speak.

"If the city wall of Hefei was reinforced with bricks, it would cost more than tens of millions of green bricks? This cannot be done in a day.

Furthermore, the small town of Hefei has nothing to do with the rest of the world, who would come to flood the city without incident?Now the people's houses are not enough, and it is imminent to build new houses. "

After Long Xiang finished speaking, he asked Lu Su again: "What does Zijing think?"

Lu Su nodded in affirmation: "What Yunqi said is true. Hefei is high and water application is low. It is quite difficult to irrigate the city with water. Unless there is heavy rain, the river will swell, but who knows? It is also possible to build new houses. of."

Seeing that Lu Su agreed, Long Xiang told Feng Zhong: "Since Zijing also agrees, this matter is settled. The cement workshop will be built next to the brick workshop. I will draw the blueprint of the cement workshop tonight. Ten craftsmen are enough for construction."

"I'll make arrangements later." Feng Zhong nodded solemnly.

"Zijing, the demand for cement is huge. After the workshop is built, it can't stop regardless of the cold or heat. In addition, the craftsmen in the workshop don't have to do other things. You first recruit more than a hundred young and strong to be used, and register them for official food and salary."

"Ok."

After Long Xiang explained to Lu Su, he stopped Feng Zhong and told him, "Uncle Zhong, you were asked to clear that piece of land last year, so you can start construction together. Now start digging the foundation according to the drawings. Now we have cement, which can be used as a drainage channel." , directly in one step.”

"well."

As Longchamp's loyal confidant, Feng Zhong is fully qualified to live in a mansion in Hefei, but he has been waiting for Longchamp's new house, and he was moved when he saw the sketch.

The dream is about to come into reality, Feng Zhong's heart is like a wild horse running wildly.

There is little rain in summer, and Long Xiang couldn't wait to train cement craftsmen during the construction of the cement workshop.

Half a month later, the first batch of cement in Hefei came out, and the first "real estate" "designed and developed" by Longchamp also broke ground in Hefei.
