In order to prepare for this conference, Qin Haijuan also spent two months writing the conference WWwlā In this paper, she not only introduces high-performance concrete, but also explores the mechanism behind this high-performance concrete from the perspective of concrete materials, for which it is necessary to propose some theoretical models that have not been proposed before.

Although Li Ruoyu and Xie Zili gave her some help in the process of writing the paper, when the paper was finally completed, Li Ruoyu still had to admit that Qin Haijuan's attainments in this field of concrete had reached a very high level, and it was in vain that Li Ruoyu handed over the opportunity to speak at this meeting to her.

When Li Ruoyu and Mi Yun returned to the office of the Concrete Association, Qin Haijuan and Xie Zili had already arrived.

Both of them knew what Mi Yun and Li Ruoyu cared about, but they just tacitly understood it.

Mi Yun also greeted the two warmly and poured fragrant tea again.

"I'm really not steady." Qin Haijuan said, "I have been thinking very immaturely about the definition of high-performance concrete, and I am worried that some people will question whether this definition is accurate. Mr. Li, you said that if someone really raises questions, how should I answer?"

"Just answer it your own way." Li Ruoyu said, "What theory will not be questioned? Even if they are academic authorities at the level of Taishan Beidou, their theories are frequently questioned. It's a good thing that someone questions it, it means that your theory can get your peers thinking, and if they want to write an article questioning your theory, it can also increase your citation rate. ”

"Hee-hee, that's true." Qin Haijuan smiled, the academic circle is very concerned about the citation rate of the paper, if a paper is often cited by other scholars, it means that the paper has high academic value, and then can reflect the academic status of the author of the paper. Even if other scholars cite it for the purpose of questioning or even refuting it, it shows that your article has the effect of throwing bricks and stones, not the kind of waste that can't be heard when thrown into the water.

Li Ruoyu said with a smile: "What you wrote is actually not bad, cement concrete is the largest man-made material in contemporary times, and the consumption of resources and energy and the damage to the environment are very huge, which is contrary to the requirements of sustainable development." Compared with the benchmark concrete, fly ash concrete greatly improves the working performance of fresh concrete, significantly reduces the heat of hydration in the hardening stage of concrete, and improves the strength of concrete, especially in the later stage. Moreover, it saves cement and reduces environmental pollution, and becomes a representative material of green high-performance concrete. We put forward green and sustainable development, are very novel ideas, I think today's expert academician Lin Hui will definitely attract attention, she is the most authoritative concrete expert in the country, if there is her support, the promotion of high-performance concrete in the country will become relatively easy. ”

Li Ruoyu hopes that Qin Haijuan will become an outstanding scholar-type concrete technical talent, and in order to reach the academic peak, this kind of experience of being questioned at a top academic conference is a must, and at the same time, it is necessary to cultivate the psychological quality of not being frightened. Having Qin Haijuan speak can help her cross the threshold from a student to a scholar as soon as possible. He believed that with Qin Haijuan's talent, she would be able to do this.

After all, there are more than a dozen concrete enterprises in Shanghai, plus several leaders of the Construction Engineering Administration, as well as a few concrete research and development centers, a total of more than 40 people.

The old man with gray temples in front of him is the national authoritative concrete expert, the only few concrete academicians, Professor Lin Hui. When Professor Lin Hui met Li Ruoyu in the previous life, Li Ruoyu was more than 20 years older than now, and he was already the chief engineer of one of the top ten concrete enterprises in the country.

Professor Lin Hui is only in his fifties, Professor Lin Hui is a student of Wu Zhongwei, the earliest concrete academician in China, and has made extraordinary achievements in the research of inorganic non-metallic materials at this time, and is one of the big bulls in this field in China.

"It is disrespectful to welcome Professor Lin to our Shanghai Concrete Association to guide the work." Li Ruoyu shook hands with Professor Lin without humility or arrogance.

Professor Lin was received by the Huhai Concrete Technology Research Center, and Li Ruoyu is now only the vice president of the Concrete Association, so these things will naturally not be done by him, but his influence in the Construction Engineering Administration and the Concrete Technology Research and Development Center is still very great. Professor Lin also listened to the leaders of the Construction Engineering Administration, and the young man in front of him was very accomplished in concrete academics.

Professor Lin Hui was able to accept the invitation to mentor the work. There is no other reason, that is, the high-performance concrete research carried out by the Huhai Concrete Technology Research Center is the first in China, and it is also doing well. And Li Ruoyu was the first person in China to propose high-performance concrete research, so Professor Lin remembered the name Li Ruoyu, but what he didn't expect was that this young man really had an expert demeanor, and he would be very good in the future.

Professor Lin also smiled and said, "You are Comrade Li Ruoyu, you are so young!" I think I didn't know anything at your age, I just knew how to do experiments after the teacher! ”

Professor Lin is very optimistic about the development of the concrete industry in Shanghai, especially the establishment of the Concrete Technology R&D Center and the Concrete Association, which is at the forefront of the country.

When the time for the meeting came, Mi Yun, who was forced out by Li Ruoyu to preside over the meeting, walked up to the podium and said in a charming and clear voice: "Leaders, experts, ......"

Today's Mi Yun is no longer the ordinary deputy director of the office when Li Ruoyu first met her, since becoming the secretary general of the Concrete Association, she has been exposed to the world more and more, and she deals with experts, scholars and entrepreneurs every day, and gradually cultivated a calm and confident temperament.

In order to be able to fully communicate with entrepreneurs and experts in the concrete industry and understand their needs, Mi Yun always finds time to go to the classes of inorganic non-metallic materials at Gongji University to listen to lectures with students, and sometimes goes to participate in technical meetings of various concrete companies.

Originally, when the association handed over this task to her, Mi Yun still wanted to shirk it, but Li Ruoyu's encouragement gave her confidence, and she herself is the secretary general, and she has presided over the meetings of the concrete association many times, this time it is just that the theme is different, and there are academicians and experts present.
