Carrying AK into Ming Dynasty

Chapter 474 Failure Is Success Damn

Cement is a powdery hydraulic inorganic gelling material, which can be mixed with water to form a slurry, which can be hardened in the air or better hardened in water, and can firmly bind sand, stone and other materials together.

There are six general-purpose civil engineering cements, namely Portland cement, ordinary Portland cement, slag Portland cement, pozzolanic Portland cement, fly ash Portland cement and composite Portland cement.

Limestone and clay are the main raw materials, which are crushed, batched, and ground to make raw meal, and then fed into the cement kiln to calcinate the clinker, and then the clinker is ground with an appropriate amount of gypsum.

"How is it? Mr. Song, can you fix it?" Although he generally knew that it would not be difficult, Liu Hongjian was not an engineering student and didn't know much about Daming's industrial capabilities, so he asked immediately.

Song Yingxing frowned while holding a few pages of cement manufacturing process. Song Yingxing didn't think it was unreliable for the typo-filled pages, and even regarded them as heavenly scriptures.

After all, the current industry of the entire Xishan Workshop comes from the typo scriptures provided by Liu Hongjian.

"There is plenty of limestone in Ming Dynasty, not to mention clay. As for the cement cellar, I still have to study it!" Song Yingxing didn't know how effective the cement was, which made his boss so excited.

But he is a rigorous person, and naturally he refuses to guarantee anything he has never done. Fortunately, although he doesn't know the purpose of this cement, the development of that weird thing called a steam engine is currently frustrated.

Anyway, idle is idle, why not help adults develop this cement first.

After some discussion, the two decided to choose the production of slag portland cement. This thing only has two hills piled up with slag from the Xishan Iron and Steel Workshop, and it is easy to gather in China.

Having made up their minds, Liu Hongjian and the two went ahead with their work, and most of the Xishan workshops were poor craftsmen who came here just for fame.

Carpenters, stonemasons, and blacksmiths are all available, and there are many people who work well. On a large construction site on the right side outside the gate of the Ordnance Institute, a small experimental cement cellar was piled up within three days.

For the past three days, Liu Hongjian didn't even return home because of the cement. He and Song Yingxing supervised the construction of the cement cellar during the day in Liu Hongjian's private luxury private room in the ordnance, thinking about the ratio of various ingredients and the grinding method.

In the evening, the two of them ate three sentences without leaving the concrete. Song Yingxing felt that his lord was possessed by a demon, and thought about whether he should report to the emperor and find some imperial doctors to show him.

On this day, according to the drawings, the cement cellar was finally supervised. Next to the cement cellar, the powdery limestone clay mixture ground by the workers was piled high. On the other side, the mixed materials (coal, iron ore slag, etc.) and gypsum powder It is also a bunch of bosses.

With an order, several folks sent the mixture into the cement cellar with shovels, ignited it and burned it for half an hour, then poured it out and mixed it with gypsum powder again, and put it into the cement cellar again for calcination.

Another half an hour later, when Song Yingxing gave the order to open the cellar, Liu Hongjian's eyes changed.

Not only can this thing be built with steel bars to build dam mouths and buildings, it's all money!

A worker opened the outlet of the cement cellar from the bottom of the side of the cement cellar, and "cement" flowed out of it with a whoosh.

The cement is black in color and emits unpleasant black smoke. It doesn't look like half cement.

"My time, what the hell is this? Why is it so dark?" Liu Hongjian's eyes turned green as he didn't see the expected cement.

"Don't worry, my lord. It may be that there is too much coal, and let the old man make it again." Song Yingxing is not in a hurry. It takes patience to develop a new thing, and it is impossible for an impatient scientist to become an expert.

That's right, I blamed myself for being too impatient. Seeing Song Yingxing's calmness, Liu Hongjian was not so earnest.

How can it be successful just once, what about the love who invented the light bulb, he has failed more than 6000 times, failure is success his mother, this is where it is.

As far as this is concerned, there is still an instruction manual. If the eyes are smeared, I don’t know how to fiddle with it until the year of the monkey.

The two stabilized their minds and began to continue the experiment.

More than an hour later, the second batch of cement was released from the cellar.

"The calcination is too light, it seems that we have to do it again." Song Yingxing grabbed a handful of the cooled product and smelled it.

After more than an hour, the third furnace came out of the cellar.

"It's too tight, no way."

……

He kept working until dark, but still failed to burn qualified cement. Liu Hongjian, who was elated at the beginning, had already lost his spirits in the afternoon, so he simply ordered someone to move a grand master's chair.

Lie down on the chair, swaying to and fro, watching Uncle Song busy with work inside and out by himself.

"Well, preheating and decomposition is a problem, and the other is air-tightness." It was completely dark, and Song Yingxing was still frowning.

"Old Song, let's fight again tomorrow! Let's go back and have some drinks." After a whole day of fighting, Liu Hongjian also knew that it was not so easy to invent any new thing, on the contrary, it was not so urgent.

In the early morning of the second day, Liu Hongjian yawned and stretched his waist and just went out when he saw that Song Yingxing had already started to direct the workers to start a war against the cement.

This Uncle Song is worthy of being a master of science and engineering. With this concentration and patience, Liu Hongjian thought to himself that he was ten blocks ahead of the experts of later generations.

"My lord is up, look quickly, the finished product seems to be working well." Seeing Liu Hongjian coming out, Song Yingxing immediately asked the workers to carry water and mud to start the experiment, and finally a smile appeared on his face.

This is already the eighth furnace. There is a table next to the crypt, with all the pens, ink, paper and inkstones. Every time there is a failure, Song Yingxing will draw and summarize the reasons for the failure. For more than a day, the waste paper is thrown into a basket.

A few workers finished the cement, moved a few bricks, covered them with cement, and built several bricks together like a wall, and mixed a lot of gravel in the cement, and just let it dry like this. on the ground.

The next step is to wait quietly for the cement to dry naturally. Liu Hongjian has long been at peace. Anyway, if he fails, it will be a big deal to start over.

At this time, Song Yingxing was nervous, because according to his estimation, this furnace was the most likely to succeed.

In order to let the cement dry as soon as possible, several carpenters simply set up a small fire next to the turning head, and it took more than an hour.

"Second gear, lord, it's done! Look!" one Min Zhuang shouted, and the other Min Zhuang lifted the brick.

The two only lifted the upper part of the brick layer, but the entire brick layer was lifted up. If it is an ordinary lime wall, it is absolutely impossible to carry so many bricks together.

"It's done? It's a success!" Liu Hongjian couldn't believe it.

"Yes, my lord, this thing is solid, and it has such a strong adhesive force." Song Yingxing smiled slightly but was not too excited.

He has developed too many things, and this cement is just one of them. He is old, so there is so much excitement.

"The cement will definitely benefit Daming, Mr. Song, you have made great contributions this time!" Liu Hongjian kicked the concrete without shaking it, and then checked the adhesion of the bricks, and then said happily.

"This is all thanks to your lord. Without those blueprints, how could I have made such a thing? I admire you!" Song Yingxing was as humble as ever.

"Hahaha!" The two looked at each other and laughed.

This situation has happened several times. Liu Hongjian came up with the blueprint, and Song Yingxing followed the blueprint to find out the solution.

"You, you, you, and you, go find an ox cart, and follow me to pull bricks into the palace to face the saint!" Liu Hongjian pointed to several minzhuang and gave orders.
