Fake Extinction of All Mankind, and I Rebuild Civilization with my Bare Hands was Broadcast Live

A cistern is no ordinary building!

when choosing building materials.

The most important thing.

That is, it must be ensured that the materials used are insoluble in water.

Otherwise it will definitely not work!

Waterproof building materials, cement is definitely the best choice!

That's right!

But the process technology required by modern cement.

Too complicated!

Just looking at the ingredients may be nothing.

Limestone may not be found though.

But can use shells instead.

The clay required is also nothing.

Iron ore fines, which can control the coagulation rate, are a tricky one.

and.

It's not over yet!

After mixing the above materials.

It is also necessary to add less than 3% gypsum to the clinker.

And these.

It's all just raw materials!

Then you need to use the rotary kiln!

Calcined belt!

Hydraulic equipment!

also.

Make modern cement and modern concrete like this.

In the step of burning the cement.

Also consumes a lot of fuel!

Energy provided by charcoal and firewood.

It can't be done at all!

Because of the process of "adding clay and limestone in, cement out".

The reaction temperature is at least around 1500 to 1600 degrees Celsius!

And need to maintain this temperature for a long, long time!

Considering the huge output of cement.

The amount of energy this process consumes is staggering!

With Jiang Kui's current kilns.

Really stretched! 700

This is also ancient times.

An important reason why it is difficult for humans to prepare cement!

Because of the level of craftsmanship and fuel supply at that time.

It is difficult to maintain such a high temperature to fire cement on a large scale, for a long time, and in large quantities!

"Huh, it seems that we have to find a way to find an alternative material.

Ate cassava.

Jiang Kui evokes the system.

Look it up in the exchange list!

Look carefully around.

Better alternatives were quickly discovered:

[Ancient Roman concrete refining technology! Exchange requires 50,000 survival points! 】

Hey!

This is kind of interesting!

The production of concrete in ancient Rome has been a mystery until now!

And it's been lost!

Ancient archaeologists and scientists have explored for centuries!

Did not want to understand.

The ancient Romans were relatively backward in productivity.

How to make building materials that are insoluble in water!

Like Roman bricks!

For example, why is the Pantheon, which existed for 2000 years, so new?

What's so mysterious about this technology?

this problem.

It has always fascinated the academic world!!!

Countless experts and scholars are rushing (bjfh)!

All want to solve this puzzle in the history of architecture!

Research to research to go.

Still no answer!!!

now.

Jiang Kui didn't expect it either.

There is a very detailed ancient Roman concrete production technology in the system!

The cheating has exploded!

The materials required for ancient Roman concrete are simple:

Sea water + quicklime + clay + sand + gravel!

The reaction temperature is also more than 1000 degrees.

No high-energy fuel is required.

Like coal!

Using only charcoal, or even just firewood, makes great Roman bricks!

And the most important thing is the waterproof performance of ancient Roman concrete!

Comparable to modern high-energy concrete!

Concrete sea wall built by the ancient Romans.

It has withstood the impact of the waves for more than 2,000 years and has not fallen yet.

It is said that it is the best waterproof building material.

Absolutely no exaggeration.

The so-called ancient Roman concrete.

Simply put, the original mortar is made by mixing lime + reef lime + seawater first!

The most important thing is the sea water!

This is also one of the mysteries of ancient Roman concrete!

Chemical reaction between concrete raw materials and seawater.

A very rare mineral is formed!

Thereby strengthening the material!

this concrete.

It has been widely used in the Renaissance architecture of ancient Rome.

This concrete is used for the roof of the Pantheon.

as of today.

Still the largest unsupported concrete vault in the world!

Also because it spans too much.

So it can't be capped.

The appearance of ancient Roman concrete was not too different from the concrete used today.

But the surface is rougher.

Very strong.

Not only easy to crack.

And it can stand for thousands of years.

By comparison.

100 years of service life for modern concrete is considered a long life.

And most importantly, the CO2 emissions from the manufacturing process of ancient Roman concrete are only about 1/3 of that of modern concrete.

Comes with an eco-friendly aura!

It's just a pity it was lost!

Jiang Kui never expected it.

The technical coverage of the system is so wide!

All lost technologies can be exchanged!

Just don't be too cool!

Thus.

All troubles are solved!

Not bad!

"System, exchange! 35

One command.

Exchange completed.

related technology and knowledge.

Instantly broke into my mind.

Almost instantly, Jiang Kui mastered the ancient Roman concrete refining technology that once made countless architectures dream!

And master the technology!

Not just for building cisterns!

The previous wood fiber concrete can also be completely eliminated!

soon.

Got an idea.

Jiang Kui will do what he says!

Finished breakfast in threes and fives.

Immediately greeted with a loud voice.

Then he carried his wooden basket on his back.

Off to the coast!

according to the required material.

He collected a huge pile of shells, rubble, and coarse sea sand on the beach!

And apart from these.

Plant ash is also essential!

so.

Salt and malt are also not to be missed!

Pick as much as you can!

Get the puree out first!

if it is possible.

Mass production again!

now.

In the live room!

The audience saw Jiang Kui collecting these familiar ingredients again.

I thought he was going to make glass again.

One after another launched a barrage:

【Yo Xi! Master Kui is going to make glass again!】

【Amazing! However, why do you still make glass? Don’t you have doors and windows?】

【Update?】

【I have to say, Master Kui really has a hand in making glass!】

【Glass King!】

Soon.

Gather relevant materials.

Jiang Kui uses a clay pot.

Filled with a large tank of sea water.

Then returned to camp.

And take action now!

He mud opened a kiln to burn the shells first.

Get quicklime!

Then burn the salt and malt.

Get grass ash!

Finally, crush the raw clay, gravel, gravel and other materials!

mixed together.

Add the right amount of the most critical sea water.

Make concrete first!

Wait ten minutes.

When quicklime and grass ash are baked.

Pour it into the mud again.

Stir it up!

Soon.

A large pile of gray-white concrete raw materials appeared on the ground...

(Five more, ask for votes!).
