The happy life of a prodigal

Tian Zhan looked at his colleagues and said: "The key to road construction is not only how to lay the foundation and how to maintain it, but also the most important thing is the material.

There is no doubt that the cement mixed with sand and gravel is hard enough. If it is well paved and flat enough, it is far better than bluestone slabs, even if it is smashed with a hammer, nothing can be smashed.

However, the cement and gravel needed are numbers beyond our imagination.

Although Xin Anhou said that as long as the road can be repaired, no matter how much money it costs, it is worth it.

However, we have to consider the issue of cost.

For 30 taels of silver, if cement roads are used to build roads, it may not be possible to finish repairing the entire capital. "

When everyone heard this, they all nodded in agreement, and said, "This is just the cost of materials, besides that, there is labor, and there are many more.

Marquis Xin'an wants to build a road, so it is naturally impossible for the carriage to bump, such absurd things.

The newly arrived material is called rubber. I saw it yesterday. It can be used for many things, among which it can be used as wheels for carriages.

This point is almost certain, and I can tell without experimenting that such a material is really suitable for the wheels of a carriage.

The speed can be improved a lot.

Marquis Xin'an is a smart person who is rarely seen in a thousand years. The reason why he wants to build roads may have a lot to do with this rubber.

After all, we all know that Marquis Xin'an is extremely concerned about this rubber.

Therefore, this road can never just be built south of the city..."

"Okay, okay, none of you know what you said, the key today is what kind of material we use, whether we use the cement mixed with sand and gravel as Xin Anhou said, or use the materials newly discovered by Lao Tian.

It's called...what's it called? "

The man said, looking at Tian Zhan.

Tian Zhan said, "Asphalt."

He paused, looked around, and then continued: "There is a lot of asphalt produced in the capital, and it was just used as mud before, so I didn't think it was useful. A student from our research institute over there got some back.

I tried it. If it is heated and then mixed with other materials such as sand and gravel, it can also be used as a road surface, and the effect is also very good, not worse than that of cement.

Although the amount of asphalt mined is not much, no one mines it. That is to say, as long as we send some people to mine the asphalt, transport it to Kyoto Prefecture, and pave it as a road surface, it will be fine and save a lot of money. silver.

The degree of hardness and the conditions in all aspects are no worse than that of cement.

Most importantly, it is much more convenient to use than cement! "

Chapter 829 Lost

"But this asphalt is a new material after all. We have never used it before. What should we do if there are other problems after it is laid?" Someone asked.

When everyone heard this, there was another silence.

Even Tian Zhan is the same.

After all, asphalt is a newly discovered material. After two or three experiments, it may be used as a road construction material, but no one can make up its mind.

Just when they didn't know how to proceed, there was a sudden sound of footsteps in their ears.

Several people turned their heads to look at the same time, and saw a familiar voice.

Several people hurriedly got up and said at the same time: "I have seen Xin Anhou."

Fang Xiu walked in front of them, had heard what they said, and asked, "What is the asphalt you are talking about?"

No one is more familiar with asphalt than Fang Xiu.

However, what he didn't expect was that without his intervention, someone else discovered the asphalt and gave it such a name.

If this asphalt is really the asphalt that Fang Xiu mentioned, it can only be said to be too coincidental.

Hearing this, Tian Zhan said in a hurry: "When you go back to Xin'anhou, asphalt is a kind of material. It was discovered by the students of our research institute. It looks a bit like mud and black, and the samples are placed in the research institute. , look."

Fang Xiu waved his hand and said: "It's okay, anyway, Master Ben is free and has nothing to do, so I will go and have a look with you."

"Yes, Lord Hou!"

Several gentlemen got up and saluted, and then Tian Zhan led the way.

The rest of the people followed behind Fang Xiu.

Although they are gentlemen, they were all craftsmen in the past, and they didn't have the so-called arrogance of literati, and they all seemed respectful in front of Fang Xiu.

Much better than those down-and-out poor gentlemen in liberal arts colleges and liberal arts colleges.

"Master Hou, when this asphalt is heated, it will take on the form of water. According to "Fundamental Physics", it is in a liquid state. It looks like nothing, but it must not be touched.

After cooling down, it will become solid again..."

Tian Zhan explained while leading the way.

The more Fang Xiu listened, the more his expression changed.

In the back, he was almost certain.

The asphalt that Tian Zhan mentioned was the asphalt that Fang Xiu knew.

Just...the name.

Fang Xiu thought of something, and his expression gradually changed.

When he saw the asphalt, his eyes narrowed slightly.

Looking at Tian Zhan, he asked, "Who discovered this asphalt?"

Tian Zhan said, "He's a student, and he's in this institute right now. If you want to see him, I'll call him over now."

Fang Xiu nodded and said: "Go, Master Ben wants to meet this person."

"Yes, Lord Hou."

Tian Zhan ran away in a hurry, and brought back a student after a while.

The student looked ordinary, probably because the conditions were a bit difficult, and his skin was not good, it should be tanned, which made him look very rough.

It belongs to the kind of person who is placed on the street, and this person walks past you, and you will not take a second look.

After seeing him, Fang Xiu asked, "Are you the student who discovered asphalt?"

The young man nodded and replied, "Yes, Lord Hou."

Fang Xiu looked at him and asked again: "How do you know this thing can build roads?"

Hearing this, the young man was slightly taken aback, and subconsciously glanced at Dean Tian Zhan.

Tian Zhan hurriedly explained: "Master Hou, you misunderstood, this kid didn't know that asphalt can be used to build roads, he just thought the asphalt was interesting, so he brought it back to the research institute.

How this asphalt can build roads is something we guessed.

When this thing is heated, some things will separate out, these things..."

Before he could finish speaking, Fang Xiu interrupted: "I'll talk about these things later, Master Ben still has some questions I want to ask him."

"Okay, Lord Hou, you ask, you ask." Tian Zhan said hastily.

Fang Xiu looked at the young man and asked, "What's your name, and where did you come from?"

The young man was a little confused when he heard this.

I don't understand why Fang Xiu asked him these questions, but he just replied: "The student's name is Li Yuan, he is a carpenter, and his family is from Kyoto Prefecture. When he was a child, he couldn't read well, so he wanted to learn a craft.

I followed a master carpenter, but I didn't learn well, and I followed a master mason, but I didn't learn well. The family members had no choice, so they wanted to send me to this engineering academy to study.

The little one is dull and doesn't know craftsman, but the students are very interested in arithmetic and all kinds of materials, engineering, the students can't learn well, Mr. Tian said that day that he wanted to recruit some people, and the students were very interested. ..."

"Okay, needless to say these words, there is another question, who got the name of this asphalt?"

Fang Xiu looked at Li Yuan, looking a little impatient.

No matter how you look at it, this person doesn't seem to come from the same place as me. In other words, this person doesn't seem to have traveled through time.

Fang Xiu was a little skeptical, whether he had survived the name Bitumen from other places.

Hearing this question, Li Yuan hesitated for a moment, and replied: "As for Master Hou, this thing looks dark, but it is actually cyan, just dark cyan. Besides, it looks like when it is raining, the raindrops are pattering. Lili, the students thought about it casually at that time, and felt that it should be given a name.

Rain black, rain green, pitch black, pitch, after thinking for a long time, I still think pitch sounds better, like a name given by someone who has studied, so the students thought of calling it pitch. "

Fang Xiu was speechless when he heard this.

After hesitating for a moment, he said again: "Master Ben will test you on a poem."

A look of surprise appeared on Li Yuan's face, and he hurriedly said, "Master Hou, none of the students have ever read a book."

Fang Xiu looked at him and said, "Odds change and even don't change...the next sentence."

Li Yuan was at a loss when he heard this poem.

After a long time, I was so anxious that tears were about to flow down. After all, I couldn't make up, so I whispered: "Master Hou, students are useless, students really can't figure it out."

When Fang Xiu got this answer, he seemed a little disappointed, waved his hands and said: "It's okay, it's not your fault that you can't compose poems, and Ben Hou Ye can't compose poems either, so there's nothing for you here, let's go down."

Hearing this, Li Yuan felt relieved, and hurriedly bowed to salute: "Yes, yes, Lord Hou, you are well."

Having said that, he left.

Fang Xiu looked at Li Yuan's back and shook his head helplessly.

There are always too many coincidences in this world.

Fortunately, he thought that he was no longer alone in this world.

For some reason, Fang Xiu felt a little depressed.

At this time, Tian Zhan next to him seemed to see that Fang Xiu was in a bad mood, and asked softly, "Master Hou, is there any problem with that student?"

Chapter 8: Give each person an extra tael of silver

Fang Xiu shook his head lightly, and said flatly, "No problem."

Then he looked at the jar of asphalt and asked, "How does this thing pave the road, have you tried it?"

Several people looked at each other and spoke one after another.

"Returning to Master Hou, I just tried it a little bit, heated this thing, mixed it with sand and gravel and other objects, and then spread it on the ground, and when it cooled, it was as hard as iron, and the effect was no worse than that cement mixture.

However, we all know the basics of cement. People in the Central Plains have also used lime mortar for thousands of years, so the cement is naturally guaranteed.

I don’t know about this asphalt, the most important thing is whether it is poisonous, if it is poisonous, I will wait..."

Several people looked at each other, but they didn't dare to continue talking.

If it is poisonous, if this thing is spread on the road, they are the eternal sinners among the eternal sinners!

When Fang Xiu heard this, the expression on his face did not change.

Of course, he knew about asphalt.

In later generations, this thing is the main material for road construction.

Walking on the road, in addition to the concrete, there is asphalt, and there are even more asphalt roads than cement roads.

Therefore, Fang Xiu looked at those people, and said: "You don't have to worry about this matter, the Marquis will ask the Imperial Doctor Bianchi from the Imperial Medical Office to come and have a look, if this thing is not poisonous, use this thing, if it is poisonous , then use other.

As for gravel, gravel, slag, if you want these things, go to Baolefang to find Wang Baole, and he will provide it for you.

Find an open space first, calculate how much money will be spent for a foot of road surface, and if it is too much, how much money can be saved...

You are all the students of the Engineering Academy, that’s all you are taught, how to do it, shouldn’t Master Ben Hou teach you again? "

When several people heard this, they hurriedly responded: "Of course it is."

Fang Xiu glanced at the asphalt again, didn't know what to think of, felt a little dazed, waved his hands and said: "I will leave the rest to you, you spend a lot of effort, this road construction can last for a hundred or a thousand years You must be serious about your actions.

Don't worry, how to do it, what materials to add, how to maintain it in case of rainy weather, whether to continue road construction or stop, these are all issues that need to be considered.

Of course, you should all know it yourself.

If it's redundant, Ben Hou Ye doesn't have much left, so try your best to do it. "

When several people heard this, they bowed together again: "What Hou Ye said is true!"

Fang Xiu glanced at them and said, "Let's go, no need to send more."

After saying that, he turned and left.

Naturally, the few people did not dare not to send them off. They hurriedly sent them to the gate of the courtyard, bowed together, and saluted: "Respectfully send off the Marquis!"
