Taking Qin Yuhuan's master and servant, the group quickly arrived at the Shaofu's location.

"This girl wants to buy some eggs. How many eggs does she want? Give him some eggs!"

Li Ming casually spoke to a young official.

"Yes, Your Highness!"

The young man who was named nodded quickly.

"Girl, I still have something to do, so I'll stay here soon!"

Nodding towards Qin Yuhuan, Li Ming took a step and left.

Although Qin Yuhuan is very beautiful, and in his twenties and eighties, he can make Li Ming fall into a trance for a moment, but at this time, he still has important things to do, and naturally he has no time to waste here.

As for who the person in front of me is.

He didn't care.

He can now concentrate on infrastructure construction.

Everything else was temporarily forgotten by him.

"Thank you, Your Highness!"

Qin Yuhuan nodded and leaned slightly towards Li Ming's leaving figure.

Li Ming, who left, quickly found the young supervisor.

"Purchase the materials above for me. In terms of quantity, the more the better!"

"In addition, find some masons for me!"

As he spoke, Li Ming casually handed over the cement-making raw materials he had written at home this morning.

The Shaofu Superintendent took over.

His eyes only glanced at it, and then he noticed Li Ming's words.

"Your Highness needs some masons?"

Open your mouth with questions.

"Yes, what's the problem?"

Li Ming nodded and spoke with some doubts.

"No, no problem!"

"I'll go and do it immediately!"

The young eunuch nodded quickly.

At this moment, although he was very confused.

In ancient times, there were obvious levels, and there were obvious differences among craftsmen, and masons were undoubtedly the lowest.

But with his previous experience, he will not ask anything at this time, but will directly accept it.

"Okay, just take care of these things quickly!"

"By the way, in addition, you can go to Chang'an to post this and arrange someone to recruit people."

As if thinking of something, Li Ming casually took out another piece of paper from his arms.

"Yes!"

The Shaofu Superintendent responded and then took the paper.

The paper is large, and there is a lot of writing on it.

When his eyes converged, the words on it were gradually reflected in his eyes.

Soon the young supervisor could clearly see the words on it.

But when he saw it clearly, his eyes couldn't help but widen.

"Just follow the instructions above. Don't mess with me. Within fifteen days, I need to recruit at least 10,000 people."

Jiang Chen didn't pay attention to the young governor's surprise, but spoke again.

And his words made the young master eunuch quickly pull back in surprise.

Then quickly responded.

"No!"

"I'll go and do it immediately!"

After responding, the young eunuch quickly retreated.

If it had been before, he might have asked at this moment.

I even have to worry about money.

But now, he is very calm.

Now the young master is really rich.

The income from selling sugar exceeded one million guan. Although most of the money was handed over to the Ministry of Household Affairs, 200,000 guan was still left for the Shaofu.

It can be said that he is wealthy.

Moreover, Li Ming's various magics, even if the cost this time will be very high, are not worth it.

Money.

Is this a problem?

Well, if Li Ming had not taken office before, the Shaofu Superintendent still felt that there was a problem, and it was a big problem.

But now that's not a problem at all.

His figure left quickly.

Later, he found the mason first.

Then comes the materials.

A large amount of materials were transported to Li Ming's location.

The production method of cement, or to be more precise, Portland cement is undoubtedly very simple. It mainly uses limestone and clay as the main raw materials, which are then crushed, batched, and ground into raw meal, which is then fed into a cement kiln for calcination.

Clinker is made by grinding the clinker and adding an appropriate amount of gypsum.

It’s hard to say how high the difficulty is.

Even the purification of refined salt is inferior.

Li Ming directed the masons to quickly enter the steps of making cement.

The first step is to be broken.

That is to say, raw meal grinding is generally divided into two types: dry method and wet method in later generations. The grinding of raw meal is completed through various instruments.

However, this was more than a thousand years ago. In the Tang Dynasty, let alone various instruments and even electricity, there was no need to think about completing the so-called dry and wet methods.

But it doesn’t have to be so complicated, just smash it into pieces.

The calcined mature material and the slag left after ironmaking are then ground together to produce cement.

The only thing to consider is proportion.

But there is also relevant information in manufacturing books.

For example, the ratio of concrete, cement, gravel and water is 1:1.4:28:0.48 to match the C25 type cement.

Another example is the C30 model cement with a ratio of concrete, cement, gravel and water of 1:1.18:26:041.

......

Naturally, the effects of cement with different proportions are different.

There is complete information on these productions, you just need to follow them.

The tall stove was raised.

Blast furnace is naturally impossible.

In the process of cement firing, there are records related to the production of stoves.

At this time, it was built by imitating a cat and a tiger.

Li Ming doesn't have much idea of ​​what effect it can have.

But there’s nothing wrong with trying it.

Firing will begin soon.

And just the next day, a pile of gray-black powdery items appeared in front of him.

"This is?"

Looking at the gray-black powder in front of him, Li Ming frowned.
