"It is precisely because of the foresight of the leaders that our country has achieved its current achievements. We must maintain this kind of achievement. The real difficulty, however, is that the state does not have enough funds to solve the problem. In recent years, we have clearly felt that many parts of our country, especially in terms of technology, have begun to stagnate, and this is the consequence of the lack of funding. With the rapid development of science and technology, this thing can only move forward, not backward. However, it is an indisputable fact that the country is in difficulty. Then, those of us who are engaged in research must make due contributions to the country, and production, education and research is a good way. It can not only allow our personnel to exercise their business capabilities, but also allow enterprises to obtain new technologies, and can improve the current decline in science and technology, which can be said to be a few in one fell swoop. At this time, Professor Lin finally began to talk about the center of today's topic.

"In 1987, a report submitted by the American Materials Advisory Committee caused a sensation: the concrete decks of some 253,000 bridges, some of which had been damaged to varying degrees in less than 20 years, and 35,000 more were added every year. Due to the widespread cracking of concrete bridge decks, the switch to high-strength concrete was made, but it seems that this did not help. According to the results of the 1995 inspection of the National Highway Cooperation Research Program, 100,000 concrete bridge decks had penetrating cracks of 1-3 meters apart within one month after the concrete was poured. It is not the strength of the concrete, but the firmness of the concrete that plays a key role in ensuring the watertightness and durability of the concrete under its operating conditions. Durability is a key issue for the future. ”

"At present, most of the foreign studies on fly ash concrete are based on the premise of the same amount of cementitious materials, changing the amount of cement and fly ash, without adjusting the water-glue ratio of concrete; The working degree of the mixture was evaluated by equal slump; The results of a comparative study on the 20°C curing specimens used to detect ordinary cement concrete are that with the increase of fly ash content and the decrease of cement dosage, the strength development rate and durability performance indicators of concrete such as carbonization resistance decrease. In fact, under the premise of improving the quality of aggregate and fly ash, changing the water-glue ratio of the mixture and appropriately adjusting the slump of the concrete mixture, it is completely possible to configure high-performance concrete with large fly ash content, strength development to meet engineering requirements, and other excellent properties. ”

"The selection of high-quality raw materials, low water-glue ratio and less cement dosage, reasonable application of mineral admixture and high-performance air-entraining superplasticizer are the main technical ways to achieve high-performance concrete. The high-efficiency superplasticizer can reduce the water-cement ratio, increase the slump and control the slump loss of concrete, and endow the concrete with high compactness and excellent construction performance. The mineral admixture fills the void of the cementitious material and participates in the hydration reaction of the cementitious material, which not only reduces the heat of hydration and improves the compactness of the concrete, but also improves the interface structure of the concrete and improves the durability and strength of the concrete. The establishment of appropriate standards and specifications, in order to make the development of this new type of concrete be reliably guaranteed, the current standards and specifications are based on the research and experiment of ordinary concrete. In order to promote the application of high-performance concrete, new standards and specifications should be based on the understanding of its many influencing factors. In order to encourage innovation, it is necessary to establish performance-based specifications, and for such specifications, reliable experimental methods must be developed, especially methods that can be tested in situ and reflect real performance, and research is needed to improve the level of application. ”

Professor Lin's words also aroused Li Ruoyu's thinking.

In modern society, nothing can be done by just one person, or a few people. Any huge plan must rely on a huge base to be successful.

Professor Lin's action in Mizuki University is to let a larger group of people agree with the topic of industry, education and research, or to extend a larger plan with this topic. The more people participate, the less people are against. After adopting different measures for different groups of people, the influence of industry, education and research in Mizuki has become greater.

If a group of gifted students do not learn much really useful knowledge in college because of a lack of research funding, then such a situation is a crime and a sign of Mizuki University is smashed. If the signboard of Mizuki University is smashed, how can the high-level management of Mizuki not be lost?

For the middle level of Mizuki University, or for those who are actually involved in industry, education and research, Professor Lin brings out the benefits and their love for the discipline. It is undeniable that there are many experts and professors in high-end institutions like Mizuki University, who are worried about the country and the people, and no one can deny their seriousness in teaching.

If the production, education and research are completed, it will help them improve their research reserves for modern science and technology in a practical sense, and will also actually train a group of students with a high level. Moreover, the research of industry, academia and research can more subsidize those experts and professors who are living a tight life because of the shortage of national funds. When there is no harm, improve your living standards, as long as you are a person who does not pump your brain, you know how to choose.

As for the rest, those huge student groups, Professor Lin did not fall behind. Is there anything more valuable for these students than to learn real knowledge? No, not at all. As a student, all he needs to do is learn and learn and learn. As long as you study well, everything else is trivial.

What industry-university-research brings to them is an opportunity for practical learning. No one likes that after four years of studying in school, it is a waste of everyone's time to go out of society and enter a company again, and to learn things that they have not learned in school before.

Now, the topic of production, education and research has solved this problem very well. Whether he wants to follow the path of research or the path of front-line workers in the future, they are all needed for practical work. Industry-university-research can fully meet their needs for practice. Although for enterprises, allowing such students to participate in the scope of production, education and research is equivalent to pulling a group of high-quality talents who are so cheap that they can be ignored.

In later generations, the experts and professors of those schools did not do such things. The top students in those schools are not in such a good mood. There are many people who take the subject and throw it directly to their own students, and then get a good reward, but they are so stingy that they are reluctant to invite their students to a meal.
