Chapter 94: High-Grade Concrete? (Seeking Subscriptions)

"It can actually adhere?"

Inside Shenji's reception room, Chen Jue's face revealed a look of delight as he looked at the two concrete blocks Liu Qing had brought back.

Previously, at Minghua Shipyard, he had tried taking out Minecraft blocks for cutting and processing, especially the synthesized [Iron Blocks], which Chen Jue had already experimented with extensively.

Cutting [Iron Blocks] into strips, slices, threads, and shaping them into cylinders were all operations he had tried.

For example, the decorations of Chen Ji's various stores were done by slicing the [Wood Log] blocks with woodworking tools and laying them down.

However, when it came to this man-made concrete, the old equipment left over from Minghua Shipyard became somewhat useless.

Either the material would explode and shatter the concrete with a single cut, or the processing accuracy would not meet the requirements, making it impossible to adhere the two cut concrete pieces together.

If adhesion couldn't be achieved with real-world techniques, there would be no technical reason to cover up the fitting of concrete blocks processed through the Minecraft system.

In this way, apart from the realistic steel materials pieced together with fasteners that could be sold (iron block slices were not for sale), the most practical and economical concrete could not be involved.

Chen Jue had even thought about giving up on the building materials business.

He didn't expect that after coming to Shenji, this old brand-name enterprise, relying on its own technical foundation, would give Chen Jue a big surprise!

"With this practical operation case from Shenji, even if I sell polished concrete blocks in the future, no one will question the technical content."

"Moreover, as long as it is concrete cast in reality, not concrete produced by Minecraft, there is a lot of room for manipulation!"

Seeing the two blocks firmly adhered together, Chen Jue admired the progress of domestic mechanical technology while his mind was full of fantasies, envisioning the production and promotion of these concrete blocks.

As for the subsequent negotiations and purchase of machine tool contracts, Chen Jue fully entrusted them to the unscrupulous merchant villager beside him.

Anyway, the funds for purchasing the machine tools were also provided by Red Star Trading, outwardly presented as a gift from a relative, and then a symbolic lease agreement would be signed.

It was simply buying equipment with Company A and then Company B leasing the equipment from Company A.

All the procedures were normal and OK, and the taxes would not be reduced.

It could also directly inject new financial vitality into old machine tool enterprises like Shenji, greatly improving Shenji's problem of talent outflow.

After all, those who have worked in the machinery industry know that many low-end equipment can indeed be bought with money, but the most difficult thing to find is top-notch talent.

Take a domestic report Chen Jue had seen as an example.

Ye Hui, a special technician at the Second Academy of Aerospace Science and Industry's 699 Factory, can achieve 5-nanometer ultra-precision tantalum wafer grinding with his skillful hands.

You should know that tantalum wafers with a surface roughness of 5 nanometers can normally only be produced with the most advanced grinding equipment.

However, Ye Hui, this top domestic grinding master, managed to grind it out with his own hands!

Although it sounds a bit like Arabian Nights, there are countless unsung heroes like this in China, and if they were in Japan, they would definitely be given the title of 'XX Immortal'.

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

After all, even the most precise machine tools have to be manufactured bit by bit by human hands.

......

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

"President Chen! Your idea of using CNC machine tools to process this prefabricated concrete building material is indeed very original!"

"May I venture to ask, what level of high-grade concrete is this? We, Shenji, also have in-depth cooperation with several large construction companies, but I have never seen anyone come up with this method."

An Yongzhi asked with a smile, subtly flattering Chen Jue, the God of Wealth who brought money to his door.

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

Concrete is widely used and highly popularized. A master decorator on the street can use it by buying a few bags of cement and sand. In fact, it has a strict classification.

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

For example, low-grade concrete from C15 to C25 is usually used for foundation bedding, non-load-bearing components, temporary buildings, and other occasions where strength requirements are not high.

Medium-grade concrete from C25 to C40 is widely used in the main structure of residential and commercial buildings, non-critical parts of roads and bridges, 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 higher requirements for structural strength and durability, such as high-rise buildings, large-span bridges, heavy-duty road surfaces, etc.

Concrete above C60 is called high-grade concrete, which is a 'treasure in the box' of civil engineers, with the characteristics of fast hardening, high strength, high homogeneity, and high density.

Nuclear power plants, national defense projects, marine engineering, etc., can easily defend against magnitude 8 or 9 earthquakes, and buildings that can withstand a few missiles without any problems are basically inseparable from this thing.

Seeing the chairman of Shenji mention it, Chen Jue also smiled slightly and started bragging: "These two pieces are the latest research and development of our Block Technology Laboratory, reaching C300 level ultra-high performance concrete, which cannot be bought outside."

As soon as An Yongzhi heard this exaggerated grade, his face immediately showed a bit of emotion: "C300 grade? Ultra-high performance? This grade value is at least able to withstand 300 megapascals (Mpa) of pressure!"

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

After An Yongzhi exclaimed, he stared at the two concrete blocks in Chen Jue's hand with the same emotion and brain supplement, thinking: "This boss from the south really doesn't fight unprepared battles!"

"The technical test for our Shenji should also be to verify whether the ultra-high performance concrete technology in their hands can be put into practice on the machine."

"If it can meet their requirements, it is estimated that it can be put into large-scale production after the machine tool is bought back."

Once he thought of this, An Yongzhi became more confident in this large contract worth 2 billion.

Of course, Chen Jue's bragging was not random.

At present, the highest grade of domestic concrete has been done to the legendary C800 level.

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

Although these two are prepared under laboratory conditions, it does not affect Chen Jue from taking them out to show off and fool these 'laymen' who are engaged in mechanical processing.

After all, every profession is like a mountain. No matter how awesome a person's knowledge and energy is, it is impossible to directly open the cheat 'eating books' like the unscrupulous merchant villager next to him who is bargaining with Zhou, the sales manager of Shenji, until he is stunned.
