Just after Chen Zhe took the girls to dig the brick kiln, the camera in the live broadcast room was given to them again.

In the picture, a small and delicate brick kiln was presented in front of the eyes of netizens, which undoubtedly aroused praise from netizens.

Today's host in the live broadcast room is Zhu Ranran, and she also followed netizens to praise Chen Zhe's brick kiln:

"Chen Zhe's efficiency really didn't disappoint us, I didn't expect the brick kiln to be built so quickly. Although it is a relatively small brick kiln, we can also see Chen Zhe's exquisite craftsmanship......

It seems that our island killer is not only good at slaying wolves, but also a skilled craftsman. ”

Netizens agreed, and some of Chen Zhe's die-hard fans also generously rewarded some props.

Zhu Ranran smiled, and suddenly said: "By the way, among the guests we invited today, there is a teacher who has a deep study in engineering construction, and he is Teacher Zhao Mingming!"

At this time, an uncle who was sitting next to Zhu Ranran with glasses, long hair and beard, and looked literary and artistic greeted with a smile: "Hello netizens, I am Zhao Mingming." ”

Zhao Mingliang is now a best-selling author, but before he became a best-selling author, he was engaged in architecture, and his construction team had undertaken the construction of many famous real estates, so he is very experienced in this area.

Zhu Ranran pointed to Chen Zhe's brick kiln in the picture and asked Zhao Mingming: "Mr. Zhao, from the perspective of your construction industry experts, how is Chen Zhe's brick kiln built?"

Zhao Mingliang immediately gave a thumbs up, nodded and said: "Chen Zhe's brick kiln is very well built, the site selection is excellent, the space is spacious, and the ventilation system is also in place...... It can be seen that he is a very careful person and knows the structure of the kiln very well.

If you burn clay bricks in the field, such an earthen kiln is already very good. ”

Zhu Ranran listened to it and nodded with satisfaction: "I am relieved to get your approval, this shows that Chen Zhe is about to burn a kiln of high-quality clay bricks, right?"

However, at this time, Zhao Mingliang shook his head and said: "Actually, this is not the case, Ran Ran, although Chen Zhe has built an excellent brick kiln, his road to burning bricks has just begun. ”

"Oh?" Zhu Ranran asked curiously, "Why is this?" Chen Zhe has obviously prepared the clay and brick kilns...... Isn't the next step to burn bricks?"

Zhao Mingliang chuckled and shook his head: "Whether it's digging clay or opening a kiln, these steps are actually not too complicated, they are all simple steps in burning bricks."

In fact, Chen Zhe's next step is the biggest problem in the process of burning bricks.

Next, he needs to make brick adobe, that is, brick billet, and only by making high-quality bricks can he burn high-quality wall tiles. ”

"Bricks?" Zhu Ranran didn't know much about the process of burning bricks, so he couldn't think of any difficulty in this step.

Isn't it just like the pottery adobe before it, kneaded into the shape of wall tiles with clay?

"Teacher Zhao, please forgive me for being a shallow learner, what is the difficulty of the bricks?" Zhu Ranran asked sincerely.

Zhao Mingliang patiently explained: "The difficulty of bricks lies in the proportion of each component in the bricks...... There is a knowledge point that I need to explain first - clay bricks are not completely made of clay, clay only accounts for about 35% to 40% of the composition of clay bricks, and the rest is other materials, such as gravel, sand, etc., ......"

Zhu Ranran really didn't know this, and a surprised expression appeared on her face when she heard it.

Zhao Mingliang was not surprised, and continued: "When it comes to the ratio of each ingredient, problems arise one after another.

How does Chen Zhe modulate this ratio?

If too much clay is placed, the fired bricks become pottery-like, too brittle, not strong, and not durable enough.

But if the clay is too little and there are too many impurities, the burned clay bricks will be too scattered, easy to crack, and even broken just out of the kiln......

The nature of the clay produced in each place itself is different, and the auxiliary materials that can be obtained locally are also ever-changing, how to balance the proportion of clay and auxiliary materials in the clay brick brick blank, which is a very difficult problem, and it is also the biggest difficulty in the process of burning bricks. ”

Hearing this, Zhu Ranran suddenly realized.

It turned out that the bricks also needed Chen Zhe to adjust the proportion of various materials in the bricks.

"Mr. Zhao, can I make such an analogy, Chen Zhe burning bricks is equivalent to cooking a pot of delicious stir-fried vegetables, and finding clay and opening a kiln is equivalent to buying ingredients and preparing a wok......

Now the ingredients and wok are ready, but Chen Zhe doesn't know the recipe, he wants to cook a delicious pot, he has to research a recipe himself?"

Zhu Ranran asked.

Zhao Mingliang laughed after listening to it: "This metaphor is very interesting, that's right, that's the truth, Chen Zhe's biggest problem now is to master the proportion of clay bricks, that is, you said to study the recipe." ”

"So how long do you think Chen Zhe will be able to overcome this problem?" asked Zhu Ranran.

"Well...... Zhao Mingliang scratched the back of his head and said, "The modulation ratio is a very complicated process, and it takes many attempts and experiments to arrive at the optimal solution." Not to mention Chen Zhe, even if he is a veteran of brick burning, when he comes to a completely unfamiliar place to fire clay bricks, he has to repeatedly make bricks, fire them into bricks, and adjust the proportions......

Therefore, I think Chen Zhe can study the appropriate ratio within a week, which is very efficient. ”

"A week?" Zhu Ranran said in surprise, "Are you saying that Chen Zhe had to study for a whole week to produce the first batch of bricks?

Zhao Mingliang said with a smile: "No way, this is the normal process, the brick wall is not a fence, it can't be built in a day......

Since Chen Zhe had decided to build a brick wall, he had to spend enough time. ”

Zhu Ranran said worriedly: "If the process of building a brick wall is really so long, then I am worried about how many times Chen Zhe will face harassment by wild beasts during the period when he is not protected by a brick wall......

Zhao Mingliang nodded regretfully and said, "Yes, there are still many difficulties and obstacles on Chen Zhe's road in the future. ”

......

Meanwhile.

Island brick kiln side.

Chen Zhe has already begun to make the first batch of clay bricks.

Yan'er watched carefully as Chen Zhe mixed the clay with some other accessories, and then asked, "Brother Xiao Chen, this is the most difficult step you said?"

"Yes. Chen Zhe patiently explained, "If you want to burn a strong clay brick, you must master the ratio of various components in the clay brick, only the correct ratio can the burned wall tiles be strong and durable."

The process of finding the right ratio is the most complicated process, if you are lucky, you may be able to try it out after a few attempts, but if you are unlucky, you may not be able to try a result in ten days and a half months......"
