Chapter 94 High-grade concrete? (Subscribe)
“Can it really be absorbed?”

In Shen Ji's reception room, Chen Jue's face showed joy when he looked at the two concrete blocks sent back by Liu Qing.

Before, when he was at the Minghua Shipyard, he had tried to take out MC blocks for cutting and processing, especially the synthesized [iron blocks], which Chen Jue had already played with to many different uses.

We have tried cutting the iron block into strips, slices, shreds, and cylinders.

Like the decoration of Chen Ji’s various stores, the wood blocks are sliced ​​and laid out by carpentry.

However, once faced with this man-made concrete, the old equipment left over from the Minghua Shipyard became somewhat useless.

Either the concrete is shattered by the explosion of the cut, or the processing precision does not meet the requirements and the two pieces of cut concrete cannot be adsorbed together.

If adsorption cannot be achieved by actual technology, there is no way to find technical reasons to cover up the fit of concrete blocks processed by the MC system.

As a result, apart from the real steel materials spliced ​​with fasteners that can be sold (iron block slices are not for sale), the most practical and economical concrete has no way to get involved.

To the extent that Chen Jue once thought about giving up his building materials business.

Unexpectedly, after coming to Shenji, this old large enterprise relied on its own technological background to give Chen Jue a big surprise!

"With this actual operation example from Shenji, even if we sell polished concrete blocks in the future, no one will question the technical content."

"And as long as it's concrete poured in reality, not concrete produced by MC, there's a lot of room for maneuver!"

After seeing the two blocks being firmly attached together, Chen Jue sighed in his heart at the progress of domestic mechanical technology. At the same time, his mind was full of imagination, imagining the production and promotion scenarios of these concrete blocks.

As for the subsequent negotiations on the contract to purchase machine tools, Chen Jue fully entrusted it to the profiteer villager next to him.

Anyway, that part of the funds for purchasing the machine tools was also provided by Red Star Trading, so we can just pretend that it is a donation from an old friend and sign a lease agreement as a token of our appreciation.

That is, Company A buys the equipment, and Company B rents the equipment from A for use.

Everything is normal and the tax paid will not be reduced.

It can also directly inject a new financial vitality into old-fashioned machine tool companies like Shenyang Machine Tool, greatly improving the problem of talent outflow in Shenyang Machine Tool.

After all, those who have worked in the mechanical industry know that a lot of low-end equipment can indeed be bought with money, but cutting-edge talent is the hardest to come by.

Take a domestic report that Chen Jue had read before as an example.

Ye Hui, a special technician at Factory 699 of the China Aerospace Science and Industry Corporation II, can achieve ultra-precision grinding of 5-nanometer tantalum sheets with his skillful hands.

You should know that under normal circumstances, tantalum sheets with a surface roughness of 5 nanometers can only be produced with the most advanced grinding equipment.

But Ye Hui, the top grinder in the country, actually ground it out with his own hands!

Although it sounds like a fairy tale, there are countless great craftsmen in China who hide their identities. If they were in the Japanese army, they would definitely be named "XX immortals".

It is the continuous efforts of these cutting-edge talents that can help domestic machine tools break through the precision limits time and time again.

After all, no matter how high the precision of a machine tool is, it still has to be manufactured bit by bit by human hands. …

Seeing Chen Jue concentrating on fiddling with the two successfully assembled concrete blocks, An Yongzhi, the chairman of Shenji who came to listen, was equally curious.

"Mr. Chen! Your idea of ​​using CNC machine tools to process this kind of prefabricated concrete building materials is really unique!"

"Excuse me, what grade of high-grade concrete is this? We at Shenji have in-depth cooperation with several large construction companies, but I've never seen anyone come up with this kind of method." An Yongzhi asked with a smile, and while speaking he patted Chen Jue, the God of Wealth who brought money to his doorstep.

The high-grade concrete mentioned by An Yongzhi is actually a high-end material in the field of engineering construction.

Concrete seems to be widely used and has a high popularity. A decorator on the street can just buy a few bags of cement and sand and use it. In fact, it also has a strict grade classification.

As for how to classify the grades, civil engineers know it best. It is determined by the minimum value of the cubic compressive strength of concrete at the age of 28 days.

For example, low-grade concrete from C15 to C25 is usually used in foundation cushions, non-load-bearing components, temporary buildings, etc., where strength requirements are not high.

Medium-grade concrete from C25 to C40 is widely used in the main structures of residential and commercial buildings, non-critical parts of roads and bridges, etc., which is the most common concrete standard in daily life.

The remaining high-grade concrete from C40 to C60 is generally used in projects with high requirements for structural strength and durability, such as high-rise buildings, large-span bridges, heavy-loaded highway pavements, etc.

Concrete with a grade of C60 or above is called high-grade concrete. It is the "treasure trove" in the hands of civil engineers and has the characteristics of fast hardening, high strength, high homogeneity and high density.

Nuclear power plants, national defense projects, marine projects, etc., which can easily withstand earthquakes of magnitude 8 or 9 and can withstand a few missiles without any problems, basically all rely on this thing.

Seeing the chairman of Shenji mentioned this, Chen Jue also smiled and said nonsense: "These two blocks are the latest developed in our Cube Technology Laboratory. They are ultra-high performance concrete that reaches the C300 level. They are not available outside."

When An Yongzhi heard this exaggerated number, his face immediately showed some emotion: "C300 level? Ultra-high performance? This number value means that it can withstand a minimum pressure of 300 megapascals (Mpa)!"

"I knew it! No wonder it can easily withstand the cutting of CNC machine tool heads. The strength of this material is almost catching up with the strength level of 'secondary steel'!"

After An Yongzhi finished exclaiming, he stared at the two pieces of concrete in Chen Jue's hand and sighed and thought to himself, "This boss from the south really doesn't fight a battle without preparation!"

"This technical test for our Shenji should also be to verify whether their ultra-high performance concrete technology can be put into practical use."

"If we can meet their requirements, we can probably start large-scale production once we buy the machine tools."

After thinking about this, An Yongzhi became more and more confident about this contract worth 20 billion yuan.

Of course, Chen Jue’s nonsense was not random.

Currently, the highest grade of domestic concrete strength has reached the legendary C800 level.

There are several preparation processes. In addition to the ultra-high performance concrete mentioned by Chen Jue, there is also a more powerful active powder concrete.

Although these two items were prepared under laboratory conditions, it did not affect Chen Jue's ability to show them off and fool these "outsiders" who were engaged in mechanical processing.

After all, different trades are like different worlds. No matter how great a person's knowledge and energy are, it is impossible for him to cheat and "eat books" like the unscrupulous villager who was bargaining with Manager Zhou of the Shenji Sales Department so hard that he was stunned.
