Next year's affairs can be discussed next year, but at present, for Zhu Yifeng, who is the governor of the capital, there are too many things that he needs to handle.

Immediately on the riverside, a huge waterwheel, with the river and turn, the waterwheel is several zhang in size, the huge waterwheel is even as big as a sailboat, when the large waterwheel rotates, the transmission shaft made of wood and iron is as thick as a foot to transmit the power of the waterwheel to the nearby shed on the dam.

"Grow, cluck, ......"

In the brick and wood structure shed, more than a dozen large stone mills made of bluestone are constantly rotating in the transmission shaft, which is a bit like a huge rice mill.

But if you look closely, the material that is not thrown into the stone mill is not rice, but small fist red or green broken bricks, which are mixed with clay fragments such as jars and pots, these broken bricks and rotten tiles are poured into the stone mill, and in the "creaking" sound of the stone mill, they are crushed into powder.

At the same time that the pieces were crushed into powder, several other stones were grinding or crushing quicklime, and in the rows of small sheds outside the shed, there were rows of dozens of iron pots, and in front of each iron pot there was a shirtless worker frying gypsum, which was heated and fried by the iron pot until the yellow-gray gypsum was pushed to the shed, and was crushed into powder along with other materials. In the end, the powder of the car needs to be mixed together in proportion to the above finely ground materials, which also becomes cement.

"What is the monthly output of the cement plant now?"

In this almost primitive cement factory, Zhu Yifeng asked.

With the creation of the factory, it has brought a series of problems, such as to run an apprentice school, to build a factory, whether it is to build a school or a factory, a large number of building materials are needed, the former can also be yellow mud, but for the plant, Zhu Yifeng has no intention of using yellow mud, after all, the plant has been used for decades, and it must be durable.

In this way, cement has become an indispensable building material, and this is precisely what China in this era, and even East Asia does not have, whether it is Hong Kong, Shanghai, the cement it needs must come from the United Kingdom, through tens of thousands of nautical miles from the United Kingdom to China, the material is expensive, far beyond the scope of factory construction can accept.

In this era when modern industry is completely zero, almost every job that needs to be carried out means that it is necessary to start from scratch and create a system step by step, just like this cement - when the price of cement is too high to afford, and the cement factory has not yet been built, Zhu Yifeng chose Tufa cement. Even in order to reduce the cost of building the "factory" and to be able to put it into production as soon as possible, he chose the simplest method of soil manufacturing - using broken bricks and rotten tiles instead of clay as raw materials.

Thanks to the extraordinary memories after the crossing, he was able to remember the contents of some miscellaneous books he had read, and then found a way to make cement by the soil method. This so-called "soil mixed cement", although its strength is not as good as that of industrial cement, but it also has some advantages. For example, this kind of cement has good acid and alkali corrosion resistance, low early strength, strong water absorption and low heat release when used, and generally takes up to 2-3 months to reach the standard strength. And the frost resistance is not as good as ordinary cement, but this cement mortar is better than using lime mortar!

"Back to the Metropolitan Governor, it can now produce 15 tons per day, but now the three towns are full of cement, so the villain is thinking about how to increase the output of cement! That's why I had the audacity to get that thing......"

Standing in front of the Grand Duke, although as the manager of the cement factory, Li Shenghe still looked extremely frightened, so that when he spoke, his legs were a little weak. Maybe he can call himself "this manager" in front of outsiders, after all, this cement factory is government-run, but he doesn't dare to call himself like this in front of the official, how many officials is this "manager"? He didn't know, but he knew that he was not an official at all, just a "grass people".

In his opinion, this metropolitan governor is an emperor who has not been an emperor, and he Li Shenghe is just the shopkeeper of a brick factory, well, although when he was young, he had a heart to fame, but God knows, he has not even been a showman in the examination for ten years, if not, how can he be a shopkeeper in the brickyard. Now seeing a character like the Grand Duke, his legs are naturally a little weak. What's more, that incident was done by himself!

"That's why you built this cement kiln!"

Looking at the cement kiln located by the river, Zhu Yifeng looked very interested, although this cement kiln looked no different from the brick kiln in the past, but he knew that this was the first "technological upgrade" since he established a factory in Wuchang, and it was completed independently by the people of this era.

The reason why he chose "mixed cement" at the beginning was because its technology was simple enough, so simple that there was almost no need to build a factory, such as water wheels, stone mills, screens, and iron pots, which were the tools for producing "mixed cement", without any technical difficulty, and even produced "mixed cement" almost on the day he came up with the formula.

The production of "mixed cement" is subject to certain restrictions, such as its raw materials - clay bricks, various clay fragments, various ceramic dish fragments, and various refractory materials, such as cylinders, basins and other material fragments, slag ash, the source of these raw materials are subject to certain restrictions, although Wuchang because the city has been burned, there are a lot of broken bricks and tiles, but there is always a day when it runs out, even the most ordinary slag ash, because the number of steam engines and the use of coal are not abundant.

In contrast, cement roasted with clay and quicklime is undoubtedly the best choice. But the construction of the cement kiln takes time, which is the reason why Zhu Yifeng did not choose it at the beginning, and over time, because he was busy with other things, he put this matter aside, but who would have thought that now it was "invented" by Li Shenghe in front of him.

“…… The villain then thought, even if this brick is burned in the soil, then he directly uses soil and lime to go to the kiln, and then wait for the burning, and then grind into powder, at the beginning, the humble position is to build a small kiln in the yard of the factory, a try, who would have thought that it actually became, and the use of it is not worse than this mixed mud, so he dared to build a large kiln with the money in the factory, this kiln can produce 3 tons of cement a day, the material can save 10%, and the labor can save 30......"

In his explanation, Zhu Yifeng secretly admired the 40-year-old Li Shenghe, although he was not an engineer, but he relied on experience and speculation, using limestone and clay as raw materials, according to a certain proportion, calcined mature materials in an earthen kiln similar to burnt lime, and then ground to make cement. Isn't that exactly how Portland cement is made?

"Small, villain, really, really didn't expect it, Ju, actually alarmed the governor, if the governor doesn't like it, please also ask the governor to punish the villain, villain, villain, this, this will fold this......"

Seeing the eyes of the Metropolitan Governor staring at the kiln, Li Shenghe's heart suddenly panicked, and he quickly knelt down.

"Look at what scares you, stand and talk back! Don't kneel! ”

Chen Duanzhengse, who was following the Dadu Governor, commanded, how could he not know that he was not in a hurry to be happy, angry, if not, how could he report to the Dadu Governor immediately after learning about this time, and as he guessed, the Dadu Governor immediately became interested and rushed here by carriage.

"Demolition?"

looked at Li Shenghe in surprise, looking at his sincere and frightened look, but Zhu Yifeng laughed.

"Why demolish? That's a good thing! ”

It is indeed a good thing, although it is difficult to change the essence of its "local law", but for China in this era, it is already an extremely rare technological progress.

"Not only can it not be dismantled, but it should also be promoted! It's about demolishing ......."

Pointing to the shed, Zhu Yifeng said.

"I also have to dismantle the equipment that mixes cement, since it is time-consuming and labor-intensive, there is no need to keep him, Manager Li, punishment? If you can innovate in the factory, why should you be punished? Not only can it not be punished, but it must be rewarded heavily, well......"

After pondering for a moment, looking at the cement kiln that was restructured from a lime kiln, Zhu Yifeng asked rhetorically.

"In this way, this invention was created by you Li Shenghe, although there is a precedent in the West, but after all, it is my first initiative in China, and it can naturally get a patent in China. Now you have two choices, one is to produce cement in the same way for twenty years from now on, and you can extract fifty yuan for every ton of cement produced, and the other is that the governor will reward you with three thousand taels at a time. Which one do you choose? ”

This kind of reward is not so much a reward as it is that Zhu Yifeng, who is in a good mood, wants to take this opportunity to send a signal to anyone who is engaged in technological research -- the study of so-called "strange and ingenious techniques" is also a way to make a fortune, and on the other hand, it is also to establish the concept of "patents" in China.

This......

The choice given by the Metropolitan Governor made Li Shenghe stunned, he simply couldn't believe his ears, he first looked at the cement kiln, and then calculated in his heart.

One ton and fifty wen, thirty tons a day, is only more than one or two pieces of silver, twenty years, it seems that you can earn six or seven thousand taels of silver, but in the future, this Wuchang City will be all built...... How can you use so much cement? If you get these three thousand taels now, and then use the money to do a business or something, how can you only earn a few thousand taels of silver in twenty years?

Seeing that he was hesitant, Zhu Yifeng, who was embarrassed, said with a smile.

"How's it going, have you figured it out? Pick that one! ”

"Return, go back to the Metropolitan Governor, small, small candidates, choose the latter!"

Hearing his choice, Zhu Yifeng looked at the nervous Li Shenghe, but sighed in his heart, hey, the person in front of him missed the opportunity to make a fortune in vain! Twenty years, twenty years of patent rights were given to him for nothing, and the result was ......

Shaking his head and sighing, looking at this cement kiln, no matter what, this is a good start! (To be continued.) )
