Travel through the Three Kingdoms

Chapter 182 Ironmaking and Cement ([-])
When Yang Yu completed the construction of the shaft furnace, the mobile phone suddenly seemed to be a little convulsive, and a lot of technologies appeared in it one after another, and there was a time limit for all of them.

For example, the firing of cement requires that qualified cement products must be fired within three months, otherwise, some materials will be cancelled.

This, in Yang Yu's view, must be realized as soon as possible, because those materials are really fascinating, but those materials are only given a name, and the specific content of these materials seems to be burnt in cement. It will continue to be displayed after the production is successful.

But fortunately, the type of cement provided by the mobile phone is the most common one. It only needs to mix limestone and clay to make cement. Although this kind of cement is ordinary, it is definitely enough in this era. That's right, this kind of cement can be used in the repair of city walls, even in the construction of some less important houses, or the construction of ordinary people's houses.

Even some road surfaces can be paved with this kind of cement, which is really practical.

In particular, the most practical thing is that it can be used to make some relatively rough iron bars to build some bridges that are not too big. In this way, some small bridges will not be repaired with wood. After a few years, they will need to be rebuilt.

This is mainly the water source of this era, which is too rich. In Youzhou, there are no fewer than dozens of rivers, large and small. If there is this concrete bridge with iron bars, the roads in the territory will be smoother. , especially these small rivers are not suitable for sailing, so there is no special requirement for bridges, they just need to be strong, and it is quite convenient to build. In the dry season, the upstream of the gate is used to build bridges.

What kind of stone arch bridge, the technical requirements of the stone arch bridge are much more troublesome than this bridge with concrete and iron bars, it is better to directly build such a simple bridge.

Naturally, in some places with beautiful scenery, Yang Yu may ask people to build stone arch bridges, which can be passed down to future generations as architectural monuments.

Big rivers, big rivers are avoided, the current conditions really do not have the ability to build bridges, but fortunately, there are really no big rivers in Youzhou.

"Haha, okay, then, let's start building the cement kiln now." Yang Yu laughed three times and decided, and now he started to prepare for the cement firing.

Moreover, this time, there is no need to recruit too many people. For digging clay, grinding stone powder, and even grinding cement powder, all the captured slaves should be used, but there are more soldiers to guard it.

As for the important part of firing, hire people to do it, and pay high wages. After all, this is a relatively dirty job, and it may even cause people to get sick.

"Brother, tell me, the lord asked us to wear such a thick mask, right? What are you doing wearing this mask?" , then, you will die of old age at home for the rest of your life, and it will be difficult for you to even marry a wife."

Yes, Yang Yu explained to them for a long time, what, this dust, if it is inhaled into the lungs, it will cause a kind of dust disease, which will kill people.However, even if Yang Yu's mouth is worn out, they don't know much about it. They just think that wearing this mask is quite uncomfortable, especially in summer, it is extremely hot, and they have to work for a while before they have to come out to take it off. He took off his mask to take a breath, but no one listened to what Yang Yu said.

Therefore, Yang Yu directly gave a ruthless sentence. Didn’t you all listen? Those who dare to take the lead are just complaining in normal times.

There is no job, there is nothing to do, and there is still land to grow at home, but, being on the blacklist and not even being able to marry a wife, that is a big deal.

Besides, Yang Yu didn't treat them badly either, the daily wages were a lot, and he just suffered a little.

"Hey, maybe, in the future, they can be allowed to wear masks in the mines. Even those slaves, in order to keep them alive for a while, should give them some thin masks, right? It's just a waste of linen. "

After all, Yang Yu is still soft-hearted, but the other mine owners don't think so. If the slave can't work, he should be driven out and let him fend for himself, or he can be slaughtered directly to save food from being wasted. Anyway, Many slaves were caught.

How do you feel, the people from Youzhou said cruelly.

However, Yang Yu likes this look. To outsiders, he must be cruel, but he can't learn from the ancients. Although outsiders are not very good, it's not very bad, right?

"My lord, my lord, the iron has been tapped, the iron has been tapped." Finally, Yang Yu waited for the good news that the shaft furnace he built was finally officially put into operation.

"Okay, okay, your wages are doubled today." Yang Yu was happy when he watched the red molten iron flow out and flow into the molds one by one, cooling down into iron blocks one by one. According to the announcement, the wages of everyone at the scene will be doubled today.

Because the mobile phone did not provide some equipment for this output, Yang Yu only made the simplest type of rail car, that is to say, the rail is made of wooden rails, and the rail car is also used for wooden carts. It is to spread thick soil on the wooden board, and then put the mold on it, which is used to hold the molten iron. When the molten iron flows out, someone will pull the wooden cart to let the molten iron flow into the mold evenly. What has flowed out is also on the soil of the wooden cart, and will not cause damage to the wooden cart below and the wooden rails.

"Hey, isn't this the prototype of the railway? Maybe, when there is a steelmaking furnace, the railway can be developed." Yang Yu came up with an idea again, that is to develop the railway, even if he can't make any machinery temporarily, but Well, there are a lot of horses in Youzhou. If you can build a railway that connects Youzhou, even if it is pulled by horses, it will be much faster than the usual horse-drawn carriages. Moreover, it should be used in some mines. It is the widest. If rail cars are used for ore transportation, the transportation volume will increase immediately.

You know, nowadays, the gunpowder team is very idle because the transportation capacity cannot keep up.

When Yang Yu's shaft furnace produced the second furnace of molten iron, many mine owners came to visit. They unanimously decided that they would also use this shaft furnace. It was very simple. Yang Yu only sold the construction drawings of this shaft furnace, and then Earned back a lot of copper coins.

"My lord, tell me, our iron output is high, is there anyone buying it?" Seeing this situation, Ju Shou expressed concern.

"There is nothing to worry about. We have a place to sell. Haven't you noticed that in the Central Plains, the war is raging at this time? Therefore, we can sell them at a low price. In this way, we can also sell their iron-making The industry has been eliminated, let them concentrate on fighting."

Yes, at this time, Yang Yu has set his sights on the Central Plains market. Even horses can be sold, or even medical technology can be exported. In this way, even medical alcohol can be sold easily.

However, if this is the case, Yang Yu needs to develop maritime transportation even more urgently. Otherwise, how can he export these things to Sun Quan, and Liu Bei also needs to find a good transportation route.
