Great Tang Southern Emperor

This series of procedures is very simple, but Li Zhen is very satisfied: "Yes, it seems that everyone is very proficient, tell everyone, work hard, as long as you can burn the finished product, His Highness will give you a lot of rewards."

"Yes, thank you, Your Highness." Wu Xiangyang looked happy, but then wrinkled again: "There is only one problem, that is, a lot of powder will leak out during the firing process, and the crops around here will be polluted by these powders." , and the villages in many fields even withered and died.”

"I know, don't worry, as long as I succeed, I will move away immediately. As for the destroyed farmland, you can compensate according to your discretion." Li Zhen doesn't care, in fact, even in later generations, firing cement Those that pollute the environment, not to mention that he is still using the local method of firing, are even more polluting.

That's right, Li Zhen was firing cement. In fact, the reason why Li Zhen asked Li Shimin for a porcelain kiln was to prepare for firing cement and glass.

Although there are huge differences in the firing equipment and firing methods of cement, glass, and ceramics, they are the same in some respects, such as the reactions are all carried out at high temperatures; Changes; Another example is that there are great similarities in raw materials, so in a certain way, the three still have a lot in common.

In particular, cement and glass are made of similar materials: cement is made by mixing limestone, clay, and gypsum and calcined at high temperature, while glass is made by melting limestone, quartz sand, and soda ash at high temperature.The degree of similarity is even higher. From some perspectives, glass and cement are actually different products of the same material fired by different firing methods.

The difference between the three is that the firing methods are different, so the firing equipment used is also different.But under the current circumstances, there is nothing to ask for, and Li Zhen can only make do with it.Simply follow the structure of the porcelain kiln and make some slight changes to build the current indigenous cement kiln. If the indigenous cement can be successful, then it will be easy to build another glass kiln according to the method of the cement kiln.

Of course, Li Zhen didn't just visit the cement kiln this time. The cement kiln had already been built, and even a lot of cement for the test had already been fired. He came here to preside over the cement strength experiment.

"Your Highness, things are here, Your Highness, please move." Wu Xiangyang stretched out his right hand and invited Li Zhen to the other side.

Under Wu Xiangyang's order, several men quickly peeled away the straw covering it, revealing the blue-gray cement board, and beside it, Ben Yin holding a sledgehammer was already in place.

"Your Highness, there are a total of ten cement slabs here. The composition ratios and firing methods are different. There are still a few that have not been completely dried. It will take a few more days."

"Well, Ben Yin, let's try this one." Li Zhen touched the cold cement slab, and saw that the color was no different from the cement pavement of later generations, but he didn't know why the strength was not up to standard.

"I am willing to serve you, Your Royal Highness." After several months of nurturing, Benyin can also speak a little Chinese, and the flattering words are the most familiar among them, and he does not know who taught him.

"Drink!" In the roar, Benyin raised the big hammer, which was tailor-made for him by Li Zhen, and it weighed 170 pounds. Most people couldn't lift it up, but it was used in Benyin's hands. But here is just right.

"Boom! Crack." The sledgehammer collided with the cement slab, making a violent roar, and then there was a sound of breaking, and the one-foot-thick cement slab was broken by Ben Yin.

"No way." Even though he was mentally prepared, Li Zhen was still a little disappointed and said, "Because the strength of this blow is only about a thousand catties, it's a bit unbearable to even a thousand catties."

"Your Highness, don't be disappointed. This is just the first piece. There are many more to come. There will always be success." Wu Xiangyang's expression was not very good, although the strength of the cement board seemed to him to be pretty good, but Li Zhen couldn't help it. If he is not satisfied, he can only deny it.

"I'm fine, I'm just a little disappointed." Li Zhenshuai shook his head, threw out all the messy thoughts, and gritted his teeth: "Ben Yin, give me a try."

"I obey, Your Highness." Benyin said respectfully, raised the sledgehammer to the second cement slab, and smashed it down.

"Boom! Crack." Disappointment flashed in Li Zhen's eyes once again.

"Boom! Kacha." Not qualified, Li Zhen's disappointment became more and more obvious.

"Boom! Kacha." Still unqualified, the sweat on Wu Xiangyang's face was about to fall.

"Boom! Kacha." It was still unqualified, and the face of Master Cement who was watching also changed color.

"Boom! Click" is still like that, huh?Li Zhen's face changed, from disappointment to surprise in an instant.

"Stop." Li Zhen shouted loudly, Ben Yin almost flinched.

No matter what the reason is, Li Zhen is now full of joy, and quickly came to the sixth cement board, and then the surprise turned to disappointment again. The sixth cement board did not break, but under the heavy blow of Ben Yin, Cracks have also appeared. This situation is much better than the previous five yuan, but it still does not meet Li Zhen's requirements.

"Your Highness, don't worry, it's just over half of the number now, and there are still four yuan left, so there must be qualified ones." Wu Xiangyang can only use these words to support himself. To put it bluntly, he is betting on the remaining four yuan. There is cement that can withstand the blow of the cause. If he has it, he will naturally have a lot of credit, but if he doesn't, although he will not be punished, it will be difficult to be reused in the future.

"I know, let's continue." Li Zhen's disappointment was only for a moment. Although the sixth piece failed, it was not broken after all. This is also a victory for Li Zhen, which shows that his thinking is right. Yes, even if none of the ten pieces are successful, as long as you try more, you will always succeed.

"Yes." Benyin continued the experiment.

"Boom! Click." Seventh piece, unqualified.

"Boom! Kacha." The eighth piece was still unqualified.

Wu Xiangyang's lips were about to be bitten, and he worshiped the gods and Buddhas all over the sky in his heart, not asking for a future or money, but only asking for one of the two remaining cement slabs to be able to withstand the big black one. Attack to make him look better.

I don't know if his prayers had any effect, or if he was lucky, when the ninth cement slab

"Boom!" The voice was obviously different from the previous one, and Li Zhen didn't need to stop it, because Ben Yin stood aside sensibly.

Li Zhen stepped forward quickly, and when the dust cleared, the ninth cement slab appeared in front of him. Looking at the cement slab in front of him, a smile appeared on Li Zhen's face.I saw a large pit on the blue-gray cement slab, which looked very miserable. Obviously, it was severely damaged by Ben's heavy blow, but it was limited to this--except for the dent, there was nothing on the cement slab. The same goes for scars, including the back.

"Because, let's do it again." Li Zhen was mainly afraid of hidden injuries on the cement board—although there were no injuries on the surface, the cracks inside were more deadly.

"Yes." Benyin swung the sledgehammer and hit the concrete slab hard again.

"Boom!" The hole on the No. [-] concrete slab was even bigger, and its appearance was even more horrible, but it was still firm.

"Okay."

"Finally successful."

"Woohoo! It's done, it's done."

"Hahaha"

""

The cheers were endless. These people had been dealing with Cement for several months, so they naturally knew what this scene meant. Seeing the success of Cement, even Li Zhen couldn't care less, and cheered happily.

In fact, Li Zhen is also very happy, the cement finally appeared, and Li Zhen is too clear about what it means.It is different from horseshoes. Horseshoes can only be said to be a technological innovation. The technical foundation is already there. With a little inspiration, individuals can succeed.But cement is different. Cement is a new material that has never appeared before. It was Li Zhen who brought it to this world from scratch. Naturally, this sense of accomplishment cannot be compared with mere horseshoes.

What's more, the horseshoe can only act on war horses, and can only bring victory to Datang, but it cannot bring a wider territory.But the effect of cement can make Datang's tentacles extend farther, because the appearance of cement means that the spread of information will be faster, and the two are completely different.

Originally, to deliver news from the Shule Dufu Mansion to Chang'an, even if the messenger ran non-stop for twelve hours a day without eating, drinking or resting, it would take about a month to reach Chang'an.But if there is a cement road, then this time will be greatly reduced to about half.What this means is naturally self-evident.

"Everyone, don't rush to be happy." Li Zhen was excited, but he knew that there was still a test that he hadn't taken yet.

"Yes, it's my subordinates who have Meng Lang." Wu Xiangyang also remembered, and quickly took out a new No. [-] cement board. The previous cement board was hammered twice by Ben Yin, and it can no longer be used as a test product. Fortunately, preparations were made early, and three pieces of each cement board were made as spares.

"Put the cement slabs on it." Li Zhen pointed to the four stone blocks next to her.

"Yes."

The cement slab was still very heavy. It was one foot long, six feet wide, and one foot thick. Three or five people couldn't lift it at all. A dozen or so men could barely lift it together.

"Next, do the stress test, Wu Xiangyang."

"This subordinate understands." Wu Xiangyang responded immediately.

Under his command, everyone worked together and kept sandbags on the cement slab. The sandbags were standard [-]-jin sandbags. The accuracy was not bad, and the error would not exceed one catty.

"Your Highness, twenty sandbags have already been placed, do you want to put them in again?" Wu Xiangyang asked next to him, looking at the pile of sandbags piled up high after burning an incense stick.
