Chapter 40 What is cement?

"Stop talking nonsense, just say, why did you come here, you are an official of the imperial court!"

Yuwen Wuji Tao.

"Isn't this missing old friends, so I came to see you?"

"fine."

Such nasty words are disgusting to listen to, but fortunately he can still say it without changing his face

The bigger Yuwen Wuji's smile was, he was very satisfied with Peng Yunyan's disgusting appearance, satisfying his own bad taste.

Who let him live in Gao's house so openly, rent-free and tax-free, and he said goodbye with a good drink.Who made Peng Yunyan the first one to get close to Li Yunjiao without being hostile by Gao Dashan?

He is definitely not jealous, Yuwen Wuji silently added in his heart.

"The emperor ordered me to come and supervise the work. Cheng'an and Gan Sidao have set up some kind of experimental field in Pingshan Village. It is said that Madam suggested that two crops of white rice can be grown a year. The emperor attaches great importance to it."

So here he is.

And he was extremely happy, and rushed here without stopping.

Did you know that you received the imperial decree at that time?He almost laughed out loud on the spot, wishing he could kowtow twice to the wise and mighty emperor.

As a result, Yuwen Wuji and Peng Yunyan became permanent residents of the Gao family.

In addition, Yu Wenxian who used "visiting relatives" as an excuse from time to time.

Staring at Gao Dashan of the two Yuwen brothers all day long like a thief, the four of them just made up a mahjong table!

During the Qingming Festival, there are many rains.

April is almost here, and Li Yunjiao's ideal "villa" is about to start construction.

Peng Yunyan suddenly found herself in trouble.

"The building material on it, cement? What is it?"

The other people also looked at each other after looking at each other.

Li Yunjiao explained clearly: "Cement is a kind of building material made by grinding sand and stone into fine powder, adding water to make concrete, and then mixing it. It has a good texture and is extremely hard after solidification. It is perfect for building walls. Cement also needs a lot of brick kilns."

Brick, brick brick?What is that again?

Peng Yunyan, who was already sure of winning, suddenly stopped, and found that the blueprints he had studied day and night, and he thought he had a plan, were just superficial skills.

He was completely stunned by these building materials alone.

Peng Yunyan looked miserable.

What is Dayan's number one architect? It's just a false name!

Li Yunjiao let out a long sigh. She was so confident that she didn't expect that it was still a backward ancient time, and she hadn't come into contact with such things as limestone, cement, and brick kilns.

Fortunately, this is overhead.Otherwise, history must not be changed?Make a world upside down!

"Forget it, I can make these things, so, Mr. Peng. I will write down the method of making cement and brick kilns, and you and Dashan will supervise the construction. Try it first, how about it."

Peng Yunyan immediately thought, if Li Yunjiao's method works, how big will it be for the construction and development of Dayan as a whole?He couldn't even think about it.

day!

What is Li Yunjiao's background?

Resolve the anxiety, but also know how to grow white rice.Now she even knows this kind of unheard of thing!

Peng Yunyan's heartbeat suddenly accelerated, and she was so excited that it was hard to express it in words.

His legs were so weak that he wanted to kneel down, he?? wanted to?? worship?? teacher!

That's right, he wants to worship Li Yunjiao as his teacher!

It's just that it didn't seem to be the best time yet, Peng Yunyan suppressed her heart throbbing, and pressed the corners of her lips tightly.

"No problem, Madam believes that since Yunyan has won, Yunyan will do her best. Together with Brother Gao, we will build a cement brick kiln for Madam."

Just do it, and within a few days, Peng Yunyan and Gao Dashan followed the method given by Li Yunjiao.First make the cement.

At present, experiments are needed, so Peng Yunyan and Gao Dashan will try to figure it out first.

Grind sand, grind into powder, and filter.Add water, settle, and beat to make quicklime.

Quicklime is added with water and mixed into concrete.

This is how cement is made!

"It's unbelievable, it's unbelievable! It's hard to believe if you haven't seen it with your own eyes."

This is cement?

Peng Yunyan stared intently at the cement experiment.

After seeing the cement solidified with my own eyes, it turned into a palm-sized stone slab, and it was so hard that the eyeballs almost popped out.

"Is this done?"

Gao Dashan touched the stone slab, which was also novel.

Unexpectedly, it was really teased by them, and I couldn't wait to show it to my daughter-in-law.

"Yunjiao, come and see, is the cement you mentioned really like this? It's really amazing. If this thing is used to build a house, our family will catch up with the iron wall!"

Gao Dashan ran home from the mountain in one breath, pushed the door of the room and shouted loudly.

Li Yunjiao tilted her head, and took the slightly rough stone slab from Gao Dashan's hand.

Walking out the door, in front of Yuwen Wuji and Gao Dashan, he fell towards a whetstone in the corner.

When there was a clang, the slate was not damaged at all.

Li Yunjiao nodded, the hardness is not bad, but the texture is a little rough.

"Well, it's okay."

Yuwen Wuji pouted silently, Li Yunjiao, why don't you go to heaven!

This kind of thing can be tinkered with.Can you be a little more flamboyant?

The hardness comparable to that of stone, if it is used in??

Yuwen Wuji took a deep breath.

After careful consideration, Yuwen Wuji realized that this cement has too many uses and is too extensive.

Used well, it is a great thing to benefit the country and the people!

Yuwen Wuji was still thinking about whether to play at this time, but was interrupted by Peng Yunyan who ran back panting.

"Brother Gao, can't you wait for me?"

He was almost exhausted.

I was running and panting all the way, afraid that I would be taken too far by the tall mountains, the kind of big trees that grow like hairs everywhere, barren mountains and wild mountains, what should I do if I get lost?

He wouldn't admit that his sense of direction would be...poor when the reference objects around him were similar!

Especially not to be discovered by that fox Yuwen Wuji, otherwise he will definitely laugh at him severely.

Maybe from now on, he will take it out from time to time to look through it.

Peng Yunyan gritted her teeth,

Absolutely not!

The cement experiment was successful, and the next step was to burn bricks.

Hired two middle-aged men from the same village, and Gao Dashan Peng Yunyan built a cave dwelling at the foot of the mountain.

Li Yunjiao deliberately explained the details that should be paid attention to when burning bricks. Gao Dashan and Peng Yunyan took turns to watch over them 24 hours a day.

After the fire is extinguished, the kiln is ready to be opened after cooling for a day and a night.

Li Yunjiao, Yuwen Wuji, including Yu Wenxian all stood in front of the kiln and waited.

"It's about to open!" Gao Dashan reminded, feeling inexplicably a little excited, and Peng Yunyan and Peng Yunyan opened the door of the kiln, one on the left and the other on the right.

The red bricks of the three kilns, and the waste of two kilns. Before the last kiln was opened, Peng Yunyan's palms were sweaty. These few kiln bricks, but he and Gao Dashan's painstaking efforts, if they fail, it will inevitably be disappointing.

But after all, it's just an experiment, even if it fails, it's inevitable.

Everyone who had already given up their minds saw the long red bricks coming out of the kiln intact, and their hearts were hanging high.

"Is this? It's finished?"

Peng Yunyan was already stuttering, she wiped her face and picked up a red brick with trembling hands, regardless of the ashes on her hands.

Pinch hard.
