Chapter 118 Making Cement

"Master, you said before that all the ores that we don't know are stored separately. At the beginning, we just put them in the warehouse. Later, there were more and more, so we had to build a house next to it specifically for storage. ore."

Karis walked and talked about the situation.

From time to time, I would look at Harvey jumping up and down behind me, wondering why he wanted to follow me.

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

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 be done in about ten days.

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

Entering inside, you will see a large amount of ore, mostly stone. Specialized personnel will reprocess the iron ore and then send it to the blacksmith shop.

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

Karis said excitedly: "Since you divided it into groups, those serfs worked very fast, and they 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 mining area."

Having a small iron mine in the territory is already a matter of celebration. As for the medium-sized mining area, only the earl can guard it.

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

If it had been in the past, Karis would have proposed selling pig iron, but now he dare not. The mining area is too large, and it cannot be easily exposed.

"Put them here first. When they are used, I'm afraid there won't be enough." Linn said.

"Why don't you sell it?"

Karis didn't mention it, but Harvey said it, "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 kids know? You can indeed make money by selling iron ore, but you need to bear the corresponding price. We don't have the strength at the moment."

Harvey didn't understand.

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

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

Next to the warehouse is a wooden house. When you open it, you will find many irregular stones piled inside. They have strange looks and different colors. Some stones are palm-sized and brown overall, while others are block-shaped and have smooth surfaces but with lines.

"Master, these are the ores I don't recognize. They are all here." Karis said.

Lin En looked at these stones carefully, frowning.

Caris and Harvey on the side were both confused and didn't know what was going on with him.

After a long time, Linn sighed. He realized that he still overestimated himself. He had not specifically learned to identify ores. He only had one concept about these stones. They were different.

This made him couldn't help but think of the novels he had read. He really didn't know how those seniors were so knowledgeable.

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

"We have cement!" Linn couldn't help but said.

"Master, what did you say?" Karis was confused.

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

"cement?"

Caris and Harvey looked at each other, very unfamiliar with this word.

Harvey even muttered, "Water and mud are mixed together. I know it is the sludge of the swamp."

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

"That's right, I've never been anywhere, not even the royal family. I also know that the second son of the Kingdom of Kais likes to wear red clothes and hang out with hairy men."

Harvey closed his mouth and did not continue.

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

Linn took a deep look at Harvey. This little kid had a lot of things hidden.

"You will know what cement is by then. Karis, you ask the mining workers to 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 crowded with people.

The serfs who sent 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 brought over ground limestone. The quantity was not large, and it took a whole afternoon to get it out.

Lin En looked at the lime powder. It was said to be powder, but in fact it was relatively small particles. Without relevant tools, it was difficult to grind limestone into powder in large quantities. In addition, the time was relatively short, so it was good to be able to do this.

There is also some iron powder accumulated next to the lime powder. This was made by the blacksmith when making iron tools. It was hammered again to make the particles smaller.

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

Lin En 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 can be ground into fine powder.

The raw materials of cement are not very precious. The key lies in this process. He probably remembers the proportions of several materials. There is no strict control. It does not mean that if you add more, it will fail. You can determine the proportion through many experiments.

However, the burning material is a problem. The current furnace temperature cannot meet the standards for firing, but the blacksmith shop can barely be used.

He discovered something before. The so-called blacksmiths are actually not that simple. They also have certain innovative thinking, but they are 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 higher-quality ores.

The shape of the latter is relatively unique. Although it still has a big belly, a triangular structure is installed inside. It is continuously polished with a very high-heat ore. After it is finally shaped into a sheet, it is pressed inside and used in gaps. Fill with soil.

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