Chapter 254 Trial and Error

Regarding the construction of cities, the land of China has a history of thousands of years, and it can be said to be very advanced and developed.

In the past, cities were built with a brick-and-stone structure, which was mostly built with a brick-and-stone wall in the Ming Dynasty. This is because of the development of brick-burning technology, brick walls are more stable than earth walls.

.

Just like the Yingtian Mansion Wall now, Lao Zhu has ordered construction to start for 25 years, but it has not been completely built.

This used almost 250,000 civilians and more than 300 million bricks.

Not to mention the location selection, foundation laying and other things, just talking about materials. Make the bricks fully glued together and play a role in stabilizing the wall. This is extremely important.

Although some use granite, some use limestone and other materials, they also use glutinous rice juice to mix lime to bond the wall, and these are now the most common bonding materials for building city walls during the Ming Dynasty.

.

People are not full, but now they need some glutinous rice juice to build walls. It seems very luxurious, but they have to do so.

It is obviously not possible to not have a solid city wall. Even if Lao Zhu doesn't do it now, some of his descendants will do these things in the future.

In fact, Zhu Xiongying is also very clear. He has spent a lot of time and energy on researching cement. But he still cannot make hydraulic lime like in later generations, and his performance and output will definitely not be particularly good.

But whether it is powerful or not, it cannot be compared with later generations. As long as it exceeds the level of this era, it will be considered a very good thing.

In fact, in another land, Roman cement has been put into use for a thousand years. Although the cement they used is quite different from the cement in later generations, the thing is indeed easy to use and has been widely used in buildings.

.

Zhu Xiongying was full of expectations because he knew the importance of cement and knew that these things could bring enough convenience to the Ming Dynasty.

Not only was the volcanic ash transported back by him, but also a large amount of lime transported back by him. He is now trying more.

Lime actually existed a long time ago. It is a building material with a wide range of uses, but now many people use lime as medicine.

A large amount of volcanic ash was carefully selected and ground by Zhu Xiongying, which seemed like a waste of time. However, he was willing to try this way. Such a silly behavior might bring more benefits.

A large amount of limestone is now being burned, and Zhu Xiongying is taking more than one route now.

Seeing the smoke and dust rolling, Zhu Xiongying suddenly became a little worried. Working in such an environment, many workers may not be able to bear the lungs.

But think about it and forget it. At this time, don’t be self-indulgent. Some things just can’t do the best of both worlds. Just like the current method of steel speculation in the Ming Dynasty, many times, prisoners are asked to fry steel speculation. Naturally, the reason is that there is a certain degree of reason.

Dangers.

At this time, don’t think about so many things, otherwise you will be asking for trouble. You can’t just see the shortcomings of these things. Make cement first and then talk about some things. You can wait for some things.

Looking at Yu Tongyuan, Zhu Xiongying explained seriously, "I have already prepared the craftsmen before, but now you have to keep an eye on them. These limestones have not been sintered yet. Pay attention to various temperatures and forms, and then carefully grind them after taking them out."
p>

Although Yu Tongyuan doesn't understand why the crown prince does this, his execution ability is still good, just remember these things.

This is also one of the reasons why he traveled thousands of miles to Changbai Mountain to transport volcanic ash. He never thought of taking advantage of the opportunity, nor did he think of digging some ash and returning to deal with the matter. He always found the best volcanic ash. As long as His Highness explains, he will naturally

Just do your best.

He also knew his ability, and compared to his father and brother, his ability was indeed good. Now, as a uncle, he is not as good as Wu Gao and Guo Zhen in the army, so Yu Tongyuan is naturally anxious. The best way is to be the best

What Your Highness has told you, don’t ask how noble you can be. As long as you make Your Highness feel that he is reliable, this is a way to stand out.

Your Highness needs people with outstanding abilities, and naturally he also needs people with reliable responsibilities. This is also a kind of diligence that can make up for your shortcomings.

Zhu Xiongying continued to explain, "Put some lime and water, mix it with sand to form mud, and add the ground volcanic ash to see if it can form something glued."

After saying this, Zhu Xiongying continued to instruct, "I have asked someone to do some things before, but what I lack now is the step of adding volcanic ash. Remember to add water and add volcanic ash proportions, and try it out. Don't worry about not enough greystone.

.Try more and explore more, it will be of great use."

Lime, sand, volcanic ash, this is a route.

Limestone fine grinding, clay, slag ash, etc., this is another route.

Fortunately, Zhu Xiongying is the crown prince and has enough resources, so he can let go of his hands and feet to arrange dozens of people to try it, and there is no need to worry about failure of the experiment and losing all the money.

Even if it takes time and effort, it doesn’t matter, because as long as one route is successful, even if it is a huge profit, the Ming Dynasty will have one more strategic material.

In fact, for Zhu Xiongying, it is not only necessary to study cement, but also to study the usage of cement.

After all, these things are also new things. The specific performance and how to exert their effects are all required to explore, and these are not so easy things.

Some things look simple, but they are not that easy to make. This is also the reason why Zhu Xiongying has not made much progress in cement research over the years. He has actually tried and missed a lot.

From the immature technology before, he kept ejecting some materials, and now he knew how to choose some limestone. If he wanted to grind some materials, the approximate temperature and thickness, he now knew some of them.

This requires constant investment and time, and these also cost a lot of manpower and material resources, which gives him the opportunity to study successfully.

Now it can only be considered as a lasting step. Without a series of accumulations in the early stage, it would be unrealistic to break this layer of window paper. Without such a simple research and creation, all of this would cost a lot.

Time and money.

A large amount of dust made Zhu Xiongying worry about pneumoconiosis, so he didn't stay in these places for a long time. If possible, let these people wear a simple mask or something. Even if the protection effect is average, it is better than nothing.

Just look at the overall situation, just make some routes, and you naturally don’t need to do the specific operations yourself.

What Zhu Xiongying should do now is wait patiently. He hopes to have a good result and hopes to have some breakthroughs.

But he didn't dare to make promises about such things. Some inventions and other things require some luck. Even though he seems to have roughly known some principles, this is just about roughly knowing some things.

Even though he has done a lot of preliminary preparations, he still cannot guarantee that he can have good results. Zhu Xiongying knows this, so he has certain expectations, but he will not maintain absolute optimism.

/p>

This is also his personality, he always maintains cautious optimism.

Before he could return to the palace, Zhu Xiongying was stopped by his fifth uncle, "Big nephew, you have to help me, there is too much living in the field. I have been thinking about it, if you are

If you don't help me, you can always help me with your predecessors."

Zhu Xiongying asked with a lot of laughter and tears, "Uncle Wu, are you kidding? Although you are in your hometown now, there are people in front of you. If you really want the eunuchs and guards to help you, how can this be fine?"
p>

"It's not your father yet!" Zhu Xu complained in an instant, and he was really anxious. "Although he protects me, he is also considerate in his work! All my people are watching. If they dare to help, your father will inevitably deal with them.

, I have to deal with me too!"

Zhu Xiongying looked embarrassed, it was really difficult, "Uncle Fifth, don't harm me! Since I don't allow my subordinates to help you, I can't do anything."

Seeing that Zhu Xiongying was about to run away, Zhu Xu would not let him go. The eunuchs under his command would inevitably be severely punished, but if some Wuxun children helped, even if they were punished, they would not be too severe.
p>

It’s not okay if you don’t find some helpers now. There is really too much life in the field. If you don’t think of a solution, you will be exhausted.

Zhu Xiongying felt depressed. Uncle Wu had the time and energy to talk about here, so it would be better to plow the ground more. Look at how good my cousin Tiezhu performed. He had already started plowing the ground skillfully, even if he had worked for a while.

After a break, I'm working.

The others failed to help, and their eldest nephew was dragged away, which made Zhu Xu happy. For no other reason, it seemed that the eldest nephew, the outsider, was helping, and it seemed that he couldn't help much.

But Zhu Xu knew that as long as he continued to harass his seemingly helpless nephew, he would soon be either scolded by his father and brother, or someone else would come to take the initiative to help.

As long as you are thicker, you can get more relaxed. Anyway, if you are scolded too much, you naturally don’t care that you will be scolded a few more times now. As long as you can be more relaxed and as long as you can complete the farming work on time and quantity, that’s fine.

.

Zhu Su can be said to have enough experience in playing a little cleverness, and he probably knows the degree of it.

As for Zhu Xiongying, he felt idle and was idle. Helping Uncle Wu and cousin, this is also part of family affection, so he feels at ease.

The cement development work is still continuing, and various experiments and experimental ideas are being carried out simultaneously. What he needs now is to be more patient, watch and guide from time to time.
