The almighty crazy concubine is tough on the audience, and the prince passes the knife behind him

The emperor and his son chatted for a while, and then Li Beimo asked Emperor Jiahe about some political matters.

When he asked about the progress of road construction, Emperor Jiahe sighed: "The raw materials for the cement you mentioned have been found, but the cement they made according to that recipe did not pass the test quality at all."

Li Beimo frowned, "Father, don't worry, I will go take a look tomorrow."

“There are many reasons why the quality of cement is not up to standard. If the ingredients of raw materials are unbalanced, the ratio is unreasonable, or unqualified raw materials are added during processing, it will lead to unqualified cement.

For example, excessive slag doping, excessive fly ash, etc. will directly affect the hardness and strength of concrete. After Cheng Qingqing finished speaking, she looked at Li Beimo and said, "Why don't I come with you tomorrow to take a look." "

"Okay." Li Beimo nodded. He has never made this kind of cement before, so he can't guarantee that he can match it well. Qingqing might as well come over and take a look.

On this day, Cheng Qingqing and Li Beimo chatted with Emperor Jiahe all afternoon. The whole family happily had dinner together before the couple left the palace and returned to the Prince's Mansion.

the next morning.

Cheng Qingqing followed Li Beimo to the cement production site.

Linghu Yuan heard that he also followed. He was very curious about what kind of cement it was. It must be something extraordinary if Cheng Qingqing could give guidance in person.

Cement making site.

Prime Minister Fan, Minister of Industry and other five officials had received the news that they were coming, and took everyone at the construction site out early to wait.

Except for Prime Minister Fan, these five people are all the officials responsible for building the road. Since they received the task of building the road, they have worked hard and did not dare to neglect it.

Construction of the highway started more than two months ago. Because it was a poverty alleviation project, the court paid a lot of money and paid generous compensation for the land occupied. The work progressed very quickly. Within a few days, many job advertisements were posted along the way. Worker.

Nowadays, highways are being built in full swing. Hundreds of miles of land have been built, but bridges are needed in some places. They are waiting for them to make cement so that they can build bridges with cement.

But until now, the cement they make is substandard, and they are not only anxious, but also afraid of losing their official title.

"Look, the carriage from the Prince's Palace is coming!" said an official.

Everyone quickly arranged their clothes and hats to prepare for the prince's arrival.

The carriage gradually approached and came to them.

"Hey!" Dong Yuxing pulled the horse's rope and the car slowly stopped.

Except for Prime Minister Fan and those officials, everyone knelt down.

Li Beimo helped Cheng Qingqing out of the carriage, and Prime Minister Fan and several officials from the Ministry of Industry came forward to greet him.

"I respectfully welcome Your Highness the Crown Prince and the Crown Princess!"

The kneeling people then shouted three thousand years old, "Welcome to His Royal Highness the Crown Prince, the Crown Princess! Thousand years old, thousand years old, thousand years old!"

"No courtesy! Everyone, get up!" Li Beimo said calmly.

"Your Highness, Crown Princess, tea has been prepared inside. Please rest inside first," said Prime Minister Fan.

"No need to rest, let's take us to the venue now!" Cheng Qingqing said.

"Yes, Your Highness, please!" Prime Minister Fan walked in front to guide them.

Everyone came to a very large venue. Cheng Qingqing looked around and ordered people to bring in the raw materials so that she could re-proportion them.

Soon, clay bricks, pottery fragments, and various refractory materials, such as fragments of jars and basins, water-quenched slag (waste from iron-making furnaces), slag ash (residues after burning various coals) and other items.

Followed by quicklime and hydrated lime.

Ling Feng and Dong Yuxing moved the simple awning they brought, set it up, and ordered others to bring in a few chairs and tables, prepare tea, and let the two masters come in to rest.

At this point, we can't blame Prime Minister Fan and the people from the Ministry of Industry for not paying attention, because they want to follow Cheng Qingqing closely to see how she compares these things.

The raw materials were all prepared, and Cheng Qingqing asked people to wash all kinds of waste and put them on the fire pit to dry.

They were busy until night. Before leaving, Cheng Qingqing left a message, asking them to grind it with stones into powder and come back to have a look.

After two days, the raw material was finally produced.

Cheng Qingqing and Li Beimo came to the cement factory again. When they saw the workers sweating profusely and not even wearing a mask under such heavy dust, they remembered that there were no masks here.

She opened her small bag, took out a stack of ordinary masks from the space, tore off the outer packaging and handed it to the Minister of Industry, "These are masks. Cement dust is very harmful to the human body. Let them do things in the future, and they must wear them." Put on a mask.”

"Yes! Crown Princess." The Minister of Industry took the mask and was about to send it to the workers.

"Wait." Cheng Qingqing suddenly stopped him again.

The Minister of Industry thought that she still had something to explain, so he stopped again.

"Do you know how to wear this mask?" Cheng Qingqing took out a mask from his hand and showed him how to put it on.

"Wei Chen knows how to wear it, thank you, Crown Princess." The Minister of the Ministry of Industry bowed again and stepped back.

Cheng Qingqing thought for a while and asked Lingbatian with her mind, "Are there any dust masks in our space?" 』

Ling Batian was helping Dongyue grow herbs in the space. When he heard her words, he immediately replied: "Yes, there are a hundred kn100 dust masks." 』

"Qingqing, if there is a cement factory in the future, this kind of masks will be indispensable. We have to prepare them for many years. We can mass-produce these masks." Li Beimo said.

"Okay, let's open another mask factory, so that we can help some ordinary people and get another job to support their families." Cheng Qingqing said.

"it is good."

The two of them clasped their fingers together and smiled at each other.

Soon, the workers added the raw material into the cement kiln, and according to the step-by-step formula, it was calcined at a high temperature of about 1450C until it was partially melted to obtain cement clinker with calcium silicate as the main component...

In every next step, Cheng Qingqing led people from the Ministry of Industry to follow closely to ensure that there would be no more failures.

In this way, they worked for a long time and finally made qualified cement.

On the way back, Li Beimo said: "Qingqing, I want to build our dormitory with concrete."

Because people here pay attention to the Five Elements theory in Feng Shui, they all use wood to build houses, which has auspicious meanings.

The wooden house has a tight structure. Although it is very strong, one of the biggest drawbacks is that if water accidentally leaks in, or someone deliberately sets a fire, the entire house will burn. The internal smoke and heat will not be easily dissipated, and it will not be able to be poured with water in a short period of time. Otherwise, if a gust of wind blows over, the fire will spread and burn the entire East Palace.

Especially if people live inside, it is very dangerous if this happens.

"Isn't the dormitory in the East Palace already under construction?" Cheng Qingqing looked at him in surprise, as if she had heard him say that it was already under construction!

"No, but the foundation has been dug and the ground dragon has been made. We are just waiting for the cement." Li Beimo said.

"Why did you think of pouring concrete to build a house?" Cheng Qingqing asked him curiously.

"Because you lived in a house like that in your previous life, and it looked good to me. So, I found a floor plan of the house on my computer, but I made some changes to the layout of the house," Li Beimo said.

"Really? You can actually modify the design drawing? What about the drawing? Let me see it." Cheng Qingqing stretched out her hand to him.

"I didn't take the drawings with me. They were placed on the table in our room in the space." Li Beimo said.

Cheng Qingqing's consciousness penetrated into the space and their room, and sure enough she saw a blueprint placed in front of the computer, and took out the design with her mind.

She took a closer look and found that the house was on three floors, and the stairs were European-shaped curved ones. "The idea is good. It has a modern sense of the 21st century, but also retains some of the style and elements here. The texture is quite good."

"This is just my first draft. Can you tell me what needs to be revised?" Li Beimo asked her.
