Datang: Time travel in two months, wait online, hurry up!

But there is no sign of chipping or breaking at all!

Seeing this scene, a smile appeared on Li Ke's face.

He knew that the cement was done!

This strength is absolutely stable.

In this era, there are no large trucks weighing tens of tons, nor cars weighing several tons.

A concrete road of this strength is basically invincible!

"It's so hard!"

The craftsmen were also stunned!

They didn't expect that the powder fired a few days ago, mixed with some water, would become such a hard stone after drying?

This is really incredible!

"Yes, continue to produce cement according to the previous method and process!"

"Let people continue to build the cement cellar, as many people as there are!"

After Li Ke confirmed that there was no problem with the cement, he immediately waved his hand and increased the intensity directly!

"Yes!"

The artisans responded loudly.

They are so motivated to have something so amazing come out of their hands!

At the same time, Li Ke also sent someone to the palace to tell Li Shimin that the samples had been prepared and asked him to check and accept them.

Not long after, a mighty carriage team came to the cement workshop.

The leader was Li Shimin, followed by the ministers in the Temple of Ganlu that day.

"Report to my father, the cement sample is finished, please check and accept it!"

Li Ke directly brought Li Shimin and others to the cement block.

"Is this made of what you call cement?"

Li Shimin and others looked at the gray-white stone slab in front of them, and couldn't help being a little surprised.

"Yes, father, you can try the strength."

Li Ke smiled slightly. You can tell how the cement is after you try it.

"How to try?"

After all, Li Shimin saw this thing for the first time, so he didn't know how high the intensity was!

"Smash it directly with a sledgehammer!"

Li Ke handed the sledgehammer he had just used to Li Shimin.

"It seems that you are very confident in this cement!"

Li Shimin glanced at Li Ke in surprise, and then picked up the sledgehammer.

He is the emperor on horseback, so his strength is naturally worthwhile.

"boom!"

Raising the sledgehammer to the cement block is a hammer!

There was a loud noise, and then everyone noticed that there was only a faint hammer mark on the cement block!

Not even cracks!

Li Shimin didn't believe in evil, and then continued to come a few times.

But no matter how much he hammered, there could only be more and more hammer marks on the cement block.

It is impossible to break or break the cement block.

"Zhijie, come and try."

Li Shimin threw the sledgehammer to Cheng Yaojin and asked Cheng Yaojin to try it too.

"Your Majesty can't break this cement block with such supernatural power, and naturally the old minister can't either."

Cheng Yaojin is a fine person, he repeatedly shook his head and refused.

Just kidding, Li Shimin can't smash it, if he smashes it, wouldn't it mean that Cheng Yaojin is better than the emperor?

He still wants to live a few more years, and he hasn't earned enough money yet!

Besides, he also understands Li Shimin's strength, after such a few blows, only a shallow hammer mark will be left.

With his strength, it is estimated that it would be difficult to smash the cement block.

Then Li Shimin looked at the other generals.

The other generals also shook their heads, expressing that they were helpless.

Seeing this, Li Shimin also understood.

Just smiled and didn't say much.

But even so, he was very satisfied with the strength of the cement stone!

because.

This has far exceeded his expectations!

PS: Fourth more! .

Chapter 112 Li Shimin hits the nail on the head!The right to operate is limited!

Cement blocks of this strength are more than enough for road construction!

After all, who is free to smash the road with a sledgehammer?

This doesn't give you a crime of destroying roads. You think Wei Zheng is a dry meal, right?

Don't be afraid of the wind or the rain, people go ~ go, the carriage runs.

He feels that there is no problem at all after decades of use.

2 guan, it will take decades to build all Zhuque Avenue into a cement road-surface.

He thought it was a good deal!

"Your Majesty, I feel that cement can be used to build city walls. The walls built in this way are fast and strong, and the cost is still low!"

At this time, Li Jing suddenly stood up and said something.

He is the leading general, and when he sees anything, he will think about whether it can have an impact and help in military warfare.

Undoubtedly, after seeing how hard the cement block was, he immediately thought of building the city wall with cement!

Most of the city walls of the Tang Dynasty were built with rammed earth, even Chang'an City.

Except that the imperial city is built with bricks at the city gate, the rest of the city is also rammed earth.

Generally speaking, rammed earth is the main material, and bricks and rammed earth are mixed in key places.

The strength of the city wall built with this material is naturally far inferior to that of cement!

If the city walls are all made of cement, then the defense strength of the city will increase many times!

"Yes, cement can indeed be used to build city walls!"

Li Ji nodded in agreement.

They all saw the potential of cement in the defense of war!

"Kel, what do you think?"

Although Li Shimin also thought it was very suitable, he still wanted to ask Li Ke's opinion.

After all, Li Ke invented cement.

No one in the entire Tang Dynasty knows cement better than Li Ke!

"Duke Wei and Duke Ying are worthy of our famous generals in the Tang Dynasty, and their strategic vision is really sharp!"

Li Ke first laughed and praised Li Jing and Li Ji.

In fact, it’s not too much to brag about. Li Jing and Li Ji, as ancients, saw cement for the first time, and they immediately thought of using it for city wall construction to enhance their war defense capabilities.

This really shows a strong strategic vision!

Furthermore, Li Jing is the military god of the Tang Dynasty. He has served as the marshal of the army many times, and has a huge influence in the army!

The same is true for Li Ji, who is also one of the top figures in the Datang Army.

These two have a good relationship and are of great help to him.

Hearing this, both Li Jing and Li Ji just smiled.

After all, this is their old line of business. After fighting for so many years, if they don't have this kind of vision, then they can't be in their current position.

"Cement can indeed be used to build city walls, and you only need to add steel bars to it, and the strength of the cement will be increased by several grades!"

"The city wall at that time, even if the enemy smashed it for a year, it probably wouldn't be broken."

Li Ke smiled slightly, and briefly explained the concept of reinforced concrete.

"Can steel be added to this cement?"

Hearing this, Li Shimin and others were stunned again.

"Of course, the reinforced concrete has a huge improvement in terms of structure and strength!"

"It is no problem to build houses with dozens of stories high."

Li Ke thought that modern buildings are basically reinforced concrete structures.

Residential buildings are tens of floors at every turn.

"Dozens of storey houses!"

Hearing Li Ke's words, everyone was numb.

They feel that they have seen many storms and waves in the first half of their lives, and they should be able to make the mountain collapse before them without changing their color.

But Li Ke brought them shock and shock time and time again.

They consider themselves well-informed.

But for what Li Ke said, the houses with dozens of stories high, it is impossible to imagine the picture in his mind.

Because in their world view, the house can only be as high as it is now, and it will collapse if it is higher.

"Your Majesty, I feel that the main roads in my Tang Dynasty can be turned into concrete roads!"

"In this way, the traffic in our Datang will be greatly improved, and the traffic efficiency will be greatly improved."

"Moreover, once a war breaks out, my Tang army can go to suppress it as quickly as possible!"

Fang Xuanling thought further, and wanted to build several main roads in the Tang Dynasty into concrete roads!

On the road paved with stone slabs, because there are gaps between each stone slab, the carriage will vibrate when driving on the stone pavement.

But the inside of the cement is incomparably smooth, and the carriage is definitely very stable when driving on it, and the driving speed will naturally be greatly improved.

Secondly, the cement road is not afraid of rain, even if it rains, you can drive at will!

This means that if there is a war in Datang, the Tang army can immediately pass through the concrete road and quickly reach the place where the war broke out.

In the past, if it was raining and the road was muddy, the speed would be very slow.

But if all the roads are made of concrete, even if it is windy and rainy, it will not affect the speed of the army at all!

"Fang Aiqing, do you know how much it will cost to repair several main roads in the Tang Dynasty?"

Hearing this, Li Shimin's eyes also flashed a little emotion, but soon thought of a very realistic problem.

No money!

Of course he knew that turning the main road into a concrete road would be of great help to Datang's transportation, military, economy, etc.

However, money is also a big problem!
