This time Li Ruoyu really had a cold and fever, and it was the strictest time since he was eighteen years old, and he was injected in the village clinic for three days in a row, and it was not until the twenty-ninth day of the Lunar New Year that he returned to normal, otherwise he would not even have a good year. Of course, in the past three days, Li Baosheng and Huang Shuying can be regarded as anxious and busy. Not only are they busy killing chickens and fish to prepare for the New Year, but they also have to worry about their son's body, they are just such a son, how can they not be in a hurry? Fortunately, God blesses, Li Ruoyu is basically fine after three days, otherwise the two old men don't know what to do in a hurry.

In the past three days, although Li Ruoyu had a high fever, he basically lay in bed because his body was very weak. Three days is not a long time, but it is not a short time, and Li Ruoyu also thought about it a lot. Now Li Ruoyu is convinced that he is indeed reborn, then the problem cannot be avoided, he no longer intends to be like in his previous life, only at ease to be the chief engineer of a concrete company, although this career seems to be good, but there are many regrets, he must make up. Not only individuals and families, but also their own construction and concrete industries.

In the past, China's concrete industry, or the construction industry, has always been through the introduction and digestion of foreign technology, the whole industry seems to be very extensive, especially in terms of construction quality, which is greatly behind the world's advanced level. Of course, after the rise of the commercial concrete industry, this situation has changed, but it is undeniable that especially in the civil buildings of the first ten years, due to the use of on-site mixing concrete and brick-concrete structures, there is no clear understanding of the durability of concrete structures, not to mention the service life of buildings from the aspects of structural design, concrete mix design, and the use of building materials. Houses built in the 10s have become dangerous, and there have even been many accidents that have collapsed.

By the time 2019 had arisen countless dilapidated houses, another problem had arisen. That is the problem of dealing with these dilapidated houses, the city is full of such houses built in ten years, if you want to demolish all these buildings and rebuild them, then who will bear the cost? If these buildings are demolished, there will also be an incalculable amount of construction waste, and how to deal with it? The service life is only twenty or thirty years, which is also a great waste of social resources.

In November 2006, the Qingyu Hotel, a famous landmark building in Qingyu City, which was "as strong as a bunker", was completely demolished, and it was only 20 years after its completion.

In January 2007, the tallest building in Hangzhou, Building 4 of the Hubin Campus of Jiangsu and Zhejiang University, was blasted as a whole, and it was only 13 years after it was built.

In February 2010, the famous landmark Sihai Hotel in Changhai City was blasted as a whole, and it was only 13 years after it was built!

……

Similar reports continue to appear in the news media, making the people feel sad and embarrassed. We have a history of 5,000 years of civilization in China, and there are many long-lived buildings preserved in history, the previous house, but to invite a few carpenters, to erect wall pillars on the ground, and put on the ridge of the rafters, purlins, doors and windows tiles, although it takes only a hundred days, it is not uncommon to live for several generations. But in modern times, the lifespan of buildings has been reduced to such an alarming degree. There are even some slips of the tongue circulating on the Internet in later generations, such as "To make money, you have to build a building, and to build a building, you have to demolish it." I will build it again after dismantling it, and the price will be doubled. "This is the pain of China's construction industry!

For example, the average life span of buildings in the United Kingdom has reached 132 years, the average life span of buildings in the United States is 74 years, and the design life span of buildings in Japan is more than 50 years.

Of course, foreign buildings attach great importance to the issue of service life from the beginning of design and planning, so they have put a lot of effort into it. Of course, on the one hand, most of the buildings such as civil housing in foreign countries were built after World War II, in the fifties and sixties, and prefabricated structures were widely used, because the concrete components used in the construction were produced in prefabricated factories, and the quality of foreign prefabricated concrete components and cast-in-place concrete was far more important than in China. Moreover, in the research of concrete structures, foreign countries are much ahead of China, and even many of China's professional textbooks or standards are borrowed from foreign countries.

Of course, it is almost impossible to change this situation by one person! Li Ruoyu also knows that although he has been reborn, has a clear grasp of the future historical development, and has mastered a lot of future technologies, it is not possible to change the future of China's construction industry and China's concrete industry. If you still follow the original development trajectory and rely on the future technology you have mastered, you will at best become the top expert in the domestic concrete industry. But how can an expert alone change the future of China's concrete industry?

Therefore, Li Ruoyu also figured out that he had to establish a super group, at least the world's top 500, or even the top 500, with such a cross-industry giant with construction as the main industry and covering related industries, leading the direction of the entire Chinese construction industry, and perhaps it would be possible to change the future of China's construction industry.

Li Ruoyu also clearly remembers that China's construction industry is still promising in the future. For example, the construction companies, construction machinery companies, and building materials companies with the prefix have developed into large groups, and some have even become the world's top 500 enterprises. For example, just a Wuyi Heavy Industry Group that started with concrete construction machinery, its boss once became the richest man in China with a net worth of 70 billion yuan, and Li Ruoyu, who has a good understanding of history, does not believe that he can not exceed this record!

Li Ruoyu remembers that at that time, he had participated in many national or Huhai concrete industry annual meetings, and the sponsors of these annual meetings, most of them were the Wuyi Heavy Industry, Li Ruoyu's home in Huhai, also collected a lot of souvenirs presented by Wuyi Heavy Industry, such as concrete mixer truck models, thermos cups, etc., it can be said that Sany Heavy Industry has expanded its influence in the concrete industry to a great extent. When it comes to Wuyi Heavy Industry, almost everyone in the concrete industry knows that it is the largest construction machinery manufacturer in China, the fifth largest in the world, and the largest concrete machinery manufacturer in the world.

Of course, Li Ruoyu also remembers very clearly that China's largest construction machinery manufacturer, is from the concrete machinery manufacturing starts, from the nineties, it has taken a step in the field of concrete machinery manufacturing, in 1994 Wuyi Heavy Industry first large-displacement, high-pressure concrete trailer pump was successfully developed, since then a comprehensive replacement of imports. In 1998, Wuyi Heavy Industry successfully developed a 37-meter pump truck, and China finally had its own long-arm pump truck. In 2009, Wuyi Heavy Industry's 72-meter boom pump truck broke the Guinness World Record, once again surpassing the ultra-long concrete pumping technology. The most striking thing is that year, Sany Heavy Industry acquired the world's first concrete brand Putzmeister in Germany, which is commonly known as the elephant company in the concrete industry, which changed the global industry competition pattern in one fell swoop.

In the field of commercial concrete, there are also many cross-provincial and municipal group companies, but most of them are state-owned enterprises, such as the famous China National Building Materials, which also has more than 100 concrete mixing plants with an annual output value of tens of billions. Of course, there are also some private concrete enterprises, which are also very large, and there are many with an output value of billions.

Li Ruoyu thinks that if he can set up his own company, march into these fields, make it bigger and stronger, and finally lead the development trend of the entire industry, it may be possible to change the future of China's construction industry. And he can also make many future advanced building technologies available in advance, such as 3D printed buildings, such as green high-performance concrete, and ultra-high-strength concrete. Let China's construction technology surpass foreign countries again, and it is not a dream to reproduce the glory of ancient Chinese architecture!

However, Li Ruoyu also knows that now he has no background and connections, and no funds, and it is not so easy to set up his own company, especially in the early nineties, the development of China's private enterprises is extremely difficult, and the private enterprises of this era are facing the problem of equal competition with state-owned enterprises is more prominent, and the same is true in the construction industry, especially in the concrete industry, there are few private concrete enterprises in the early nineties.

And the problem of capital is also a big problem, what to do with the company without money? However, Li Ruoyu thought about it for three days and also thought of a good solution, that is, stocks! That's right, the Chinese stock market in the nineties was a bull market. He still remembers that in 1990, Shenzhen Development (000001) 1 share was divided into 32 shares, and the par value of each share changed from 88 yuan to 2.75 yuan, and later rose to more than 140 yuan, even if he only bought 27,500 yuan of Shenzhen Development, he could earn more than 1 million yuan in a few months;

On May 21, 1992, the trading price restrictions of the Shanghai stock market were all lifted, and under the stimulus of this good news, the market opened at 1260.32 points from 616.99 points, an increase of 104.27% over the previous day, which was also the first time that the Shanghai Composite Index broke through the 1,000-point mark. In just three days, the prices of each stock have skyrocketed, with an average increase of 570%. Among them, 5 new stocks soared by 2,500% to 3,000%. In the year and a half that followed, the Shanghai Composite Index soared by more than 1,300 points.

How could Li Ruoyu, who still has fresh memories of several major events in the development of China's stock market, not make good use of the advantages brought by rebirth? He decided that after returning to Shanghai after the Spring Festival, he would seize those opportunities and dig out the first pot of gold for the establishment of his super concrete empire.
