Peek at my diary, Cao Cao dominates the Three Kingdoms

Chapter 607 Red Brick and Cement

After Lu Yan talked with Zhuge Liang, he completely tied Zhuge Liang to his warship.

"As long as Kong Ming can grow up quickly, with his ability, I should be able to retire early, right?"

Lu Yan fantasized about his fairy days after retiring at the age of 40, humming an unknown song, and walked towards his mansion.

Huang Xu, Lu Xun, Chen Dao and others have all entered the Taixue to study.

Guo Yi is also studying hard under Guo Jia's "forced" recently, and plans to be admitted to Taiyuan Academy next year.

The bustling Hussar General's Mansion in the past is missing these most noisy guys, but now it seems a little deserted.

Huang Wudie has also grown up and turned into a slim girl.

I heard that Huang Zhong and his wife wanted to find a good family for Huang Wudie. This made Guo Yi, who had always been secretly in love with Huang Wudie, anxious. hand board.

Although the trivial things in life are trivial and complicated, if you calm down and have more patience to feel and savor them, they will actually have a different taste.

"A wave in a wave. A wave in a wave"

Lu Yan hummed a little tune and returned to General Hussar's Mansion.

However, before he had time to enter the gate of the mansion, two young men in the clothes of the general supervisor and apprentice came running over in a hurry.

"Lu Hussars! Lu Hussars!"

"Success! We succeeded!"

Lu Yan stopped and turned around to look at the two apprentices, and asked suspiciously, "What succeeded?"

"Red bricks!" replied one of the apprentices.

"And cement!!!" another added.

The two of them were just like the second general Hum Ha, you and I talked endlessly.

It wasn't until smoke came from the throats of the two people that they were talking, that Lu Yan suddenly said: "Oh, I remembered!"

When Lu Yan proposed to build artillery last year, he mentioned red bricks and cement.

At that time, although Lao Geng and Ma Jun asked about the production method and approximate raw materials in detail, Lu Yanji was not very clear, and what he said was vague, and only talked about the approximate process and raw materials.

Lu Yan only remembers that the raw materials needed for cement are lime powder, clay and slag, and then these things are then calcined and mixed with water to form cement. This is also the easiest way to make cement.

With the current equipment and technology, only the most primitive cement can be produced, at most comparable to Roman cement.If you want to achieve the quality and strength of cement in later generations, it is simply a dream.But for this era, even the strength of Roman cement is completely sufficient.

Hearing that the red brick and cement have been successfully developed, Lu Yan was in a daze for a while. After all, with the appearance of cement and red brick, the future construction may undergo earth-shaking changes.

At this moment, Lu Yan felt that the soul of his infrastructure madman had awakened!
After being dazed and excited, Lu Yan quickly came back to his senses, and he said to one of the apprentices: "You, go to the shipyard as quickly as possible to find Zhuge Liang, and ask him to go to the prison as soon as possible. !"

The apprentice straightened his back, imitating the military sergeant and gave a nondescript military salute, saying: "The villain takes orders!"

"Da da da!"

As the first apprentice ran away, Lu Yan said to the other apprentice: "Go to the county guard's mansion and inform the prefect Liu, and ask him to go and serve as the prisoner immediately!"

"The villain has orders!" The apprentice also gave a similar military salute, then turned around and ran towards the sheriff's mansion.

Lu Yan asked the servants in the mansion to bring the white dragon horse, and rushed to the general as the prisoner as fast as possible.

After leaving the city, Lu Yan galloped on his horse.

Soon, he came to Jiangzuojian. The small town that expanded again?

When they came to the intersection of the town, Geng Liang and the others had been waiting for a long time.

"I've seen Lu Hussars!" Geng Liang led several officials who would be in charge of prisons, and saluted Lu Yan from a distance.

Lu Yan jumped off his horse, handed the reins to the little official who came up to meet him, and shouted: "Old Geng!"

Geng Liang's body became more and more fat. Lu Yan looked at him and couldn't help but said: "You should eat less meat on weekdays. If you keep getting so fat, all kinds of diseases will come to you."

Geng Liang smiled and said in a nonchalant tone: "We grew up hungry, and at that time we couldn't eat meat once a year. Now I occasionally dream about the hard life in the early years.

I am not afraid of being sick, but I am afraid that one day the good days will suddenly disappear.

So this meat, can't stop! "

The corner of Lu Yan's mouth twitched, and he didn't bother to persuade him anymore.

"Take me to see the red bricks and cement. If it is really what I want, all craftsmen, handymen and officials involved in the development will be given three months' salary bonus!"

"Wow!!!"

"Woo! Got rich!!"

"Thank you Lu Hussar!"

Several officials around Geng Liang jumped and laughed in ecstasy.It seems that these people are all officials involved in the development of cement red bricks.

Geng Liang's face was serious, and he scolded: "How can you be so presumptuous in front of Lu Hussar!"

After being reprimanded by Geng Liang, these officials immediately calmed down obediently, but the eyebrows and eyes they threw at each other still showed the unconcealable joy in their hearts.

Under the leadership of Geng Liang, Lu Yan came to the northwest position of the prison center.

This used to be the place where iron smelting and forging agricultural tools and armor were made. Since the iron smelting and forging departments were separated, it was temporarily used as a research and development site for cement and red bricks.

Along the way, after Geng Liang's introduction, Lu Yan had a general understanding of the development of red bricks and cement.

Compared with cement, red bricks were quickly refined by craftsmen.

After all, red bricks, or fire bricks, only need to use clay to make adobes, and then use coal cakes and bricks to enter the kiln for firing. The process is roughly the same as firing blue bricks.

"When the red bricks were just successfully fired, after testing by the craftsmen, it was found that the red bricks were actually slightly inferior to the green bricks in terms of firmness and durability."

"However, the firing process, consumption, cost, etc. of red bricks are much lower than those of green bricks.

In general comparison, red bricks with simpler production and higher output can be applied in more places and in a wider range in the future. "

Geng Liang told Lu Yan the conclusions drawn by his craftsmen one by one.

Lu Yan nodded while listening: "Although the quality of red bricks is not as good as that of blue bricks, if it is combined with cement, it will be perfect."

Hearing the cement, Geng Liang couldn't help exclaiming: "The cement is really a magical thing, I'm afraid only a genius like you can figure it out!"

Lu Yan ignored Geng Liang's flattery, but said, "Take me to see the cement first."

Geng Liang wiped the sweat from his face, and replied, "Here."

　It took a long time to fall asleep last night, but after calming down today, it is the wisest choice to understand the country.

　　Although it is emotionally difficult to accept, it should still return to rationality.Support the country and believe they will not let us down.

　　Come on!
