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

thought here.

Jiang Kui immediately ordered Da Bai to be on guard.

Then open the brake mechanism of the wooden cow and the horse.

Park it under a tree.

Get ready to go and find out!

but.

Taking into account the stability of the collapsed soil layer.

It's not okay to jump off like that.

In case of another collapse in the middle.

That wouldn't be fun.

so.

Necessary security measures can not be less.

In order to prevent trouble in the future.

Jiang Kui took out a thick hemp rope from the warehouse.

One end is tied to a stout arbor.

On the other end is a chain buckle.

tied to his waist.

Chain buckle is a kind of knot that is more commonly used.

The design is very clever.

As long as it is not cut off by external force.

Even the rope endures an irresistible force.

The buttons won't come off either!

Instead, it gets tighter.

quite safe.

With it.

Even if there is another collapse below.

Just dig up in the direction of the rope.

You must be able to escape.

Because many times.

Being buried in the ground is not scary.

The most terrifying thing is after the burial. "Seven Three Three"

People lose their sense of direction.

Can't tell where it is at all.

where is the next.

Even if the necessary discrimination can be made by gravity.

It is not easy to find an exit.

so.

Safety ropes are important.

soon.

Fasten the safety rope.

Jiang Kui turned around.

Control the lowering speed of the rope with both hands.

One side along the landslide.

keep going down.

The collapse is at least five meters deep.

The air inside is very humid.

There is a lot of water vapor.

Roots of various trees.

criss-cross in between.

mess up!

Compress the available space to the extreme.

Very depressing.

Resist the extreme lack of space.

Jiang Kui was careful all the way.

Five minutes passed.

Only step by step came to the bottom of the landslide.

After arriving at the place.

Jiang Kui looked around.

But after looking around.

But nothing special was found.

thinking.

He came aimlessly to the fractured rock formation.

I patted it with my hand.

moment.

The frosted texture of falling dust and off-white rock formations—

Finally let him find out!

This is……

Limestone?!

A thought flashed by.

A sudden light flashed in my mind!

see.

Jiang Kui hurriedly leaned over.

Pick up a piece of gray-white gravel with a fairly regular shape from the ground!

It's about the size of a palm.

TÉ......

micrite structure…

block structure...

If he guessed right.

This should be typical granulated limestone!

Formation of granular limestone.

Most of them are masterpieces of water transport and sedimentation!

widely distributed.

But mainly formed in shallow sea environment!

Different from biological skeleton limestone.

That is, calcium carbonate, such as shell bones.

This limestone is the key to firing quicklime and making the material hydraulic!

at the moment.

Ancient Roman concrete by Jiang Kui.

It has no hydraulic properties.

In other words, when it hits water.

It does not harden naturally like cement.

This effect can only be achieved by firing, heating, etc.

This will be a big hassle for waterside operations.

but.

With this kind of limestone.

There is no need to worry about such issues.

Just follow the ratio given by the system.

in a certain proportion.

Add enough quicklime to the concrete.

The hydraulic hardness of ancient Roman concrete can be achieved!

Make it sturdy and easy to style!

Become an enhanced version of Super Concrete!

If so.

Even modern cement.

Compare with it.

Also brother-in-law!

See Jiang Kui makes another discovery.

The viewers who are watching the live broadcast send out a barrage one after another:

【What did Master Kui find again?】

【Is it some kind of ore again?】

[Fuck! This thing looks a bit like a diamond at first glance! 】

【Nani? Diamond?】

【No way?】

at the same time.

Inside the Global Studio.

See the off-white rock that Jiang Kui is holding.

Alonso immediately recognized the real person.

Before waiting for the host to ask a question, he said leisurely:

"It's a sedimentary limestone..."

"It is a relatively common stone, and its main ingredient is calcium carbonate."

"Similar limestones generally contain dolomite and clay minerals. When the clay mineral content reaches 25% to 50%, we call it argillaceous rock."5

“When the content of dolomite reaches 25% to 50%, it is called dolomitic limestone. 35

"Limestone is widely distributed, homogeneous in lithology and easy to mine and process. It is a very versatile building material. After firing, it can be turned into slaked lime of extremely high purity, and by adding clay, it can be turned into modern cement. , should be good news...

"This thing works with concrete, which can make the concrete get hydraulic, that is, it can react when it encounters water, and it will be more convenient to use it to build a house.

【cement?】

【I see!】

[Concrete + cement? Kui Ye is not developed now! 】

【What do you mean? Super cement?】

【Fuck! This thing is a good thing! 】

[6666!]

Eagle Sauce Audience:

【This island of Chinese people is really rich in mineral resources! It is simply a treasure island!】

East Win Audience:

[Actually, we were all wrong, where is he starting from hell, it is clearly a dream start! 】

Korean audience:

[Yeah! But this live broadcast is getting more and more interesting! I don't know what kind of buildings he will use these materials to make? 】

the other side.

The live stream continues!

He hesitated for a while.

Jiang Kui throws away the limestone.

Immediately follow the same path back to the ground.

Take the wooden basket out of the warehouse.

Then go down to the landslide again.

Smash rock formations with a copper axe.

Collected a lot of limestone.

There were four round trips in total.

Just filled the warehouse.

The limestone under the landslide is in great reserves.

Building a building is not a problem.

It can fully meet your daily needs.

Get it in the car first.

Come back later when you need it!

soon.

After returning to camp.

Jiang Kui put down the firewood.

Then break the ground and open the kiln for the first time!

Get ready to burn the lime!

The method is the same as calcining shells.

No difference.

The only difference is to control the furnace temperature.

But this problem is not difficult for Jiang Kui at all.

Just for a while.

Under the blessing of the fire, the limestone reacts!

After half an hour.

Wait until the fire is completely extinguished.

Jiang Kui was the first time.

Break open the kiln.

Through the grate.

You can clearly see the white rubble left in the furnace tunnel!

Mash these crushed stones.

High-quality quicklime can be obtained.

Then just follow a certain ratio.

Add it directly to the concrete.

Both can react.

Because there is already hydrated lime (shell powder with water) in the concrete.

As such.

It should be possible to turn concrete into hydraulic super cement!

So as to achieve underwater work!

thinking.

Jiang Kui did not delay.

Take it immediately and crush the burnt limestone.

Then add it to the concrete according to a certain proportion.

Ancient Roman concrete was inherently good.

Strong sturdiness.

Persistence is also sufficient.

But this thing has a great disadvantage, that is, it does not apply external force, it is too slow...

It's really too slow.

An example was when the reservoir was built earlier.

At that time, if Jiang Kui didn't use fire.

Possibly until now.

The concrete in the gap will not be completely dry.

The reason is that the lime content is not enough.

If it is applied in a dry place.

That problem is easier to overcome.

Just take the fire.

But if it is applied in a damp place.

This is going to be a tricky question.

Can be improved if possible.

Added quicklime to the original recipe.

this shortcoming.

It can be completely ignored!

Because of this.

Building materials not only have the characteristics of Roman concrete.

It also has a very high water hardness!

Even in a humid environment, it will not affect the construction!

Strong group!

Soon.

Modified concrete.

As expected by Jiang Kui!

Not only has it become more delicate.

The problem of water hardness has also been solved!

Completed a qualitative leap in an instant!

With these materials.

Complete the embankment, absolutely no more.

thinking.

He hastily loaded the concrete into the warehouse.

Then bring the relevant tools.

All the way to the river...

(Three shifts, ask for votes!).
