Live streaming life: The ancients begged not to stop

With this cement road, he can mobilize the army on a large scale and give the Huns a severe blow!

Great Sui

Yang Jian was still worried about the issue of his successor. Yang Guang had been beheaded, but Empress Dugu still opposed Yang Yong becoming the crown prince.

After reading the information on the sky screen, he decided to cut the Gordian knot. Whoever of his sons could make cement independently would be made the crown prince!

We first put limestone, clay, and iron ore powder into the kiln to burn. To maintain the temperature, we also need a little coal powder. The limestone accounts for about 75%, the clay accounts for 8%, the iron ore powder accounts for 1%, and the rest is coal powder.

[The material is fired at about 1,500 degrees Celsius to make clinker, then some gypsum is added and ground into a fine powder to make the cement you need.]

too easy!

Emperors of all dynasties felt that cement was much simpler to make than perfume. They had no problem smelting iron, so making cement should be no problem at all.

Ming Dynasty

Zhu Di looked at the finished cement product and thought about the roads and buildings in the future. He decided to make cement at all costs so that the Great Wall could be repaired with cement.

Repair the roads across the country.

This would require a huge amount of cement.

However, if it is so simple to make, then many people in the folk should be able to make it, so he planned to build only a few kilns in the imperial farm as reserves for the court.

Purchase large quantities of cement from private sources.

"The recipe on the sky curtain is a state secret. Anyone who secretly spreads it to the grasslands will be executed along with their entire family!"

Qing Dynasty

Heshen almost knelt down and kowtowed to Tianmu. He was worried about this matter, but unexpectedly Tianmu taught him the method of making cement.

This can save a lot of money.

Now that the materials are ready, we need to start work quickly. If we make Qianlong wait too long, who knows what trouble will arise.

"The Emperor has decreed that upon completion of the tower, one side should be painted with a large image of a phoenix flying through peonies, and the other with a blue dragon stepping upon the sea. I decree this."

It doesn't matter. There are people who can do things like painting.

……

[Cement production is quite simple. Here's a hydraulic breaker for you. With this, you don't need to break cement manually.]

There was a simple mechanical diagram on the skylight, which many ordinary people could not understand at all. Some people went to ask the old carpenter how to make it.

"Why are you asking this? Do you still want to make cement? This is a water-driven machine, which is not suitable for our area at all."

After saying that, he continued drinking.

Daqin

Li Si looked at the mechanism carefully and almost understood the principle. This thing should be very simple for the Mohists. All they had to do was find a suitable river.

"Prime Minister, I'm afraid natural rivers aren't suitable." Mo Bi studied the area carefully. "We have wet and dry seasons here, and the flow of the river isn't very stable."

"What can you do?"

"We can build a pool, fill it with water, and let the water evenly hit the leaves outside, so that the machine can move at a constant speed."

Li Si didn't quite understand it either, so he just told the Mohists to just do it.

Ming Dynasty

Zhu Youxiao understood the mechanism on the sky curtain at first sight. Since the sky curtain occasionally mentioned that he was not doing his job properly, he had made a lot of changes.

I haven't done any carpentry work for many days.

But there was chaos in the court. The civil servants didn't think about how to govern the country all day long, but were always fighting for power and profit. He had no way to deal with it.

Not to mention the military generals, all they did was ask the court for money.

Not as pure as these institutions at all.

"Issue an order to build some cement factories in Ming as well, and to recruit refugees to repair the roads. The money will be provided by both the Imperial Household and the National Treasury."
