With the creation of basic industries, laying the foundation is more important than anything else for its overall development.

If you want the basic industry to develop by leaps and bounds, and if you want the basic industry to make drastic changes, then fundamentally speaking, this is fundamentally inseparable, and the cement that can quickly build the required facilities can be made!

In the current building materials of the Ming Dynasty, the adhesives required are relatively mixed.

Among them, the demand for glutinous rice juice, straw slurry, and triad soil is the largest.

Although the above-mentioned adhesives have added their own color to Chinese architecture, there is still a big gap compared with cement with strong moldability, good viscosity and good quick-setting effect.

"If you just build a roof, build a stove, etc., and these buildings have a long service life, then the best effect is to use triple soil.

With the passage of time, in terms of the toughness of the building itself, cement is by no means a triad of soil!

Because of the triple soil, it will become stronger and stronger over time!

However, in terms of short construction time, the strength of the compressive strength and the fast-curing effect of cement, it is more domineering in this aspect. ”

With the description of the meaning of output value, Zhao Zongwu had a new idea in his heart, because if he wanted to ensure the output value, he had to build the corresponding production line.

And the construction of the industry to which it belongs needs to have a certain foundation.

Although it is said that cement has been calcined on Juehua Island, Zhao Zongwu obviously knows better in his heart that the calcination degree of cement is different, and the effect expressed by the finished product is also different.

The construction of the Jinzhou Lingbao Group can be said to have exhausted the high-quality cement of Juehua Island!

Thinking about this clearly, Zhao Zongwu felt that it was necessary, and then stated the direction of cement calcination to the craftsmen of the research institute.

"Who is in charge of the development of cement in the workshop?" Thinking of this, Zhao Zongwu frowned, "Ben Jiang has something to ask!" ”

"My lord, it's the small one who is responsible for the development!" A big man walked out of the crowd, his expression seemed to be Vino, but he gave people a steady posture.

As an old man of Juehua Island, Niu Dabao is the first craftsman to successfully calcine cement, which also makes him have his own unique views on cement calcination.

Zhao Zongwu asked rhetorically: "But Niu Dabao? ”

Niu Dabao nodded and responded: "Back to the adult, the small one is Niu Dabao!" The words were even more excited.

"What problems can I encounter in the process of calcining cement?" Zhao Zongwu didn't have time, waiting here for Niu Dabao to calm down, and he asked straight to the point.

As the production process of cement, it uses limestone and clay as the main raw materials, and finally makes raw meal through several processes such as crushing, batching, and grinding;

Then it is sent to the cement cellar, calcined the mature material at high temperature, and then the clinker is added with an appropriate amount of gypsum, and the process is finely grinded.

Niu Dabao bowed down and said: "Back to adults, I did encounter problems that could not be solved!"

I don't know why, in the process of calcining cement, ten kilns, there will always be one or two bad kilns, and the cement taken out is used for building construction, which is broken when touched, and the texture is crisp and loose! ”

Firing cement is not as simple as imagined, and there are many problems in it.

Regarding the situation that Niu Dabao just explained, three or four hidden dangers instantly appeared in Zhao Zongwu's mind.

"The situation you are talking about is nothing more than the following.

First, in the process of calcining cement, the required temperature is not stable, or due to the shortage of coal and stone, or due to the lack of air, which leads to the temperature of the calcining kiln mouth is in a floating situation;

If this happens, it will lead to uneven heating of the cement raw meal in the kiln during calcination, which will affect the quality of cement.

Second, after a long time of calcination at the kiln mouth, it is inevitable that there will be poor sealing, which makes the excess air enter the hot kiln mouth, so it also leads to the uneven deformation of the calcined cement;

Once this is the case, it will also affect the quality of the cement.

Third......"

Zhao Zongwu is like a wise man at the moment, telling Niu Dabao everything he knows in his heart, the purpose is to reduce detours!

To the craftsmen of the seminar, their family is simply a saint!

Because only a saint knows everything, knows everything!

Otherwise, Zhang Tie really didn't know how to explain Zhao Zongwu's situation, and they couldn't think of any better explanation.

"Yes, yes, yes!" When Zhao Zongwu was telling, Niu Dabao's eyes flashed with essence, which was a thirst for knowledge!

kept repeating like a fool, but no one came out to accuse Niu Dabao, because now he has already entered a wonderful realm.

That's what keeps him improving.

"What the adults said is really right, with these guarantees, the small ones will be more determined in their hearts for the cement distinction next!"

When Zhao Zongwu told Niu Dabao about some common knowledge, after being systematically absorbed, Niu Dabao even thought of it in his mind!

Everything in this world is carefully classified, no matter which category exists, there are many small divisions under it, and the same is true for cement.

According to the different materials and the different calcination temperatures, the quality of the calcined cement is inevitably different, which makes the direction of its investment also different.

Some are burn-resistant, some are frost-resistant, and some are ......

Different ways of existing, the cement required for construction must be different.

Zhao Zongwu said with a smile: "If you can understand this, the general will be very relieved of you in his heart!"

Originally, I was worried that for cement development, you would be fixed in the same field of vision, and you would not humbly adopt some different ideas inside.

Since everything in the world has this detailed and clear division, cement, a rare product, must also have a detailed division.

Although we can't completely conclude the division of cement at this stage, we must increase our efforts for experimental discussions! ”

Cement suitable for road construction may not be suitable for factory needs!

The cement suitable for the factory is not necessarily suitable for the needs of water conservancy construction!

Cement suitable for water conservancy is not necessarily ......

Zhao Zongwu is very clear about these basic arguments in his heart, but this does not mean that others are clear, so he must tell everything he knows, because only in this way can he really become stronger!

Innovation is not easy, even if it is the cement that can be seen everywhere in later generations, as the biggest reliance of the infrastructure madman, what Zhao Zongwu can give now is to provide ideas, as for how to develop it, it still needs the efforts of the craftsmen under his command!

With a treasure like Niu Dabao, Zhao Zongwu really didn't know that even if he didn't succeed in his heart, it would be a very difficult thing!
