I, a fallen nobleman, started the farming system

Chapter 118 Making Cement
"Master, you said before that all unknown ores are stored separately. At the beginning, we only put them in the warehouse. Later, there were more and more, so we had to rebuild a house next to it for storage. ore."

Karis was talking about the situation while walking.

From time to time, I would look at Harvey who was bouncing behind me, wondering why he followed me.

Today they are going to the ore warehouse to see the results of this period of time.

The warehouse is built far away from the mining area, because the felling team has not yet cut down the surrounding trees, but according to their efficiency, it is estimated that it will take about ten days.

It is said to be a warehouse, but it is actually a yard with a huge area. You can see serfs carrying ore in and out.

Entering the inside, what you see is a large amount of ore, most of which are stones. Special personnel will reprocess the iron ore and send it to the blacksmith shop.

The number of blacksmiths is too small, and the efficiency is relatively slow, which leads to a large amount of iron ore accumulated in the warehouse.

Karis said excitedly: "Since you divided them into groups, those serfs worked very fast, and found that the iron ore output in the mining area is quite high. It may not be a small mine, but at least a medium-sized mine."

Owning a small iron mine in the territory is already something worth celebrating. As for the medium-sized mines, only the Earl can keep them.

"Master, what should we do with these iron ores?" Carliss asked, "Those blacksmiths alone are not enough to make a large number of iron tools. They can make weapons, but not armor."

If left in the past, Carliss would have proposed selling pig iron, but now he dare not, the mining area is too large, but it cannot be easily exposed.

"Let's put it here first, and when we use them, I'm afraid they won't be enough at all," Lynn said.

"Why don't you sell it?"

Carliss didn't mention it, but Harvey said it out, "I heard that iron ore is very valuable. So much iron ore can be sold for a lot of money."

Karis glared at him, "What do children know? Selling iron ore can indeed make money, but you need to bear the corresponding price. We don't have the strength at present."

Harvey didn't understand.

Lynn interrupted Karis, "It's useless to explain this to him, take me to see other ores."

Harvey curled his lips and muttered, "Don't you just look down on my young age?"

Next to the warehouse is a wooden house. When it is opened, there are many irregular stones stacked inside, with strange appearance and different colors. Some stones are the size of a palm, and the overall appearance is brown, while others are lumpy, with a flat surface, but there are bars.

"My lord, these are the ores I don't know, and they're all here," Carliss said.

Lynn looked at the stones carefully, frowning.

Karis and Harvey on one side were puzzled, not knowing what was going on with him.

After a long time, Lynn sighed. He realized that he still overestimated himself. He hadn't learned ore identification specifically. He only had one concept for these stones, and they were different.

This made him couldn't help thinking about the novels he had read, and he really didn't know how those seniors were so knowledgeable and versatile.

Fortunately, it was not without some gains. Lynn noticed a gray-white stone with textures on it. If he remembered correctly, it should be limestone.

"There is cement!" Lynn couldn't help but said.

"Master, what are you talking about?" Karis wondered.

Lynn pointed to limestone, "I saw it in a book, it can be used to make something called cement."

"cement?"

Karis and Harvey glanced at each other, this word was very strange to them.

Harvey muttered even more, "Water and mud are mixed together, I know, that's the sludge from the swamp."

"You also know the swamp. It seems that you have been to many places."

"That is, I have never been anywhere, even the royal family has been there, and I know that the second son of the Kingdom of Kais likes to wear red clothes and flirt with hairy men."

Harvey closed his mouth and did not continue.

Karis was listening enthusiastically, but suddenly there was no follow-up, and felt a little uncomfortable.

Lynn took a deep look at Harvey, this little kid has a lot of things hidden.

"At that time, you will know what cement is. Carliss, let the miners bring them to find this kind of stone. The more the better, Harvey, you go and call the other blacksmiths to Willy."

At noon, Willie's blacksmith shop was already full of people.

The serfs who brought the ore did not choose to leave. They heard that the lord wanted to make something called cement.

They were curious about what cement was and what it was used for.

A serf sent over the ground limestone, but the quantity was not large, and it took a noon to get it out.

Lin En looked at the lime powder and said it was powder, but it was actually relatively small particles. Without relevant tools, it was difficult to grind limestone into powder in large quantities. In addition, it took a relatively short time to do this, which is already good.

There is also some iron powder piled up next to the lime powder, which was produced by the blacksmith when making ironware, and was hammered again to make the particles smaller.

Everyone present had puzzled expressions on their faces. They didn't understand why they did these things.

Lynn was thinking about how to make cement. He had read it in a textbook. In fact, it was very simple to make. It was nothing more than mixing lime powder, iron powder, clay and a small amount of coal powder together and then burning the clinker. .

As long as the clinker is successful, it is fine to grind it into a fine powder.

The raw materials of cement are not so precious. The key lies in this process. He probably remembers the ratio of several materials. This is not strictly controlled. It does not mean that if there is more, it will fail. It can be determined through many experiments.

However, the burning material is a problem. With the current furnace temperature, it is not up to the firing standard, but the blacksmith shop can barely use it.

He had discovered something before that the so-called blacksmiths were actually not that simple. They also had certain innovative thinking, but they were not used in making tools, but in blast furnaces.

There are two types of forging blast furnaces in the blacksmith shop, one is a traditional furnace, and the other is specially used to forge some ores with higher materials.

The shape of the latter is quite unique. Although it is still a big belly, a triangular structure is added inside, which is to use a kind of extremely hot ore for continuous grinding. After it is finally flake, press it inside and use it in the gap Soil for filling.

However, because the strength of the soil is not high, it needs to be replaced once it is not burned, which is particularly troublesome.
