This night, Li Ruoyu was in a state of excitement, and after making a phone call, he continued to write his thesis, and it was not until 12 o'clock in the evening that Li Ruoyu stretched his waist and finally finished writing this paper of more than 6,000 words. Li Ruoyu mainly discussed the benefits of fly ash application on concrete engineering structure and concrete working performance, and the durability of concrete mixed with fly ash has been greatly improved, which is of great significance for prolonging the service life of concrete structure.

Li Ruoyu also wrote in this paper that due to the emergence of large-scale concrete structures in recent years, the cross-sectional size of the components has increased accordingly, the design strength grade of concrete has increased, the cement grade used has increased, and the unit consumption has increased, the content of cement tricalcium silicate has increased, and the fineness of grinding has increased. During the cooling period, the temperature shrinkage of the concrete causes elastic tensile stress, and a large number of cracks are found when some concrete structure formwork is just removed, and the existence of these cracks greatly affects the service life of the concrete structure and even the building. Increasing the content of high-quality first-grade fly ash to more than 20 percent, or even 30 percent, will not be harmful to the concrete structure, but will only bring more benefits.

After writing this paper, Li Ruoyu lay on the bed for a long time and couldn't sleep. He will go to Germany next week to investigate, which means that the Shanghai ready mixed concrete industry will usher in a leapfrog development, and he will also become one of the leading figures in this leapfrog development. Thinking about it, it feels like a dream, so that the goal is getting closer and closer, and the time to dig the first pot of gold is even more urgent, Li Ruoyu decided to take time to go to the stock exchange market tomorrow afternoon to test the water, and then go to his sister Bai Yurou's house on the weekend.

Li Ruoyu thought about it a lot, and didn't fall asleep until more than two o'clock in the morning, and when he woke up, it was already eight o'clock in the morning, and he was less than half an hour away from work. Fortunately, Li Ruoyu acted quickly, washed his face, brushed his teeth and ate breakfast, and it was done in half an hour.

When Li Ruoyu came to the office of the technical quality department, in addition to Zhou Jing, two technicians and a data clerk had already arrived. As soon as Li Ruoyu stepped into the door, the three people in the office all rushed to greet him warmly, and even Li Ruoyu saw that the data clerk Nie Xiaoqing helped him make tea again, and the smell of jasmine tea soon wafted in the office.

Li Ruoyu smiled and said: "Sister Xiaoqing, thank you! You don't have to be so polite in the future, everyone is a colleague!"

Nie Xiaoqing pursed her lips and smiled, and said charmingly: "Oh, this is how it should be! Xiao Li, you are just like my brother, isn't it what my sister should do to take care of my brother!" Nie Xiaoqing was even thinking, but unfortunately he was older after all, and he looked too ordinary, otherwise......

Li Ruoyu didn't know what Nie Xiaoqing was thinking, everyone had nothing to do today, because the fifteenth day of the first lunar month had not yet passed, so there was no construction site to start, and there was no production task for the mixing plant. A few people began to chat.

In less than ten minutes, suddenly there was a sound of footsteps, and several people turned their eyes to the door, but they saw Li Ziqiang, the manager of the administrative department, walking to the door with two policemen.

Before Li Ruoyu had time to think about it, Li Ziqiang walked in and said with a smile: "Comrade Xiao Li, these two public security comrades have made a special trip to thank you! You have also sent a pennant to our company, and your deeds should be vigorously commended and will add a lot of glory to our company!"

Li Ruoyu only remembered at this time that Captain Liu had said that he would send someone to clarify his going to the Public Security Bureau, but he didn't expect that the person he sent was still this iceberg policewoman.

Zhou Yuwei didn't want to come, but her father seemed to know about it, criticized her fiercely, and asked her to come to Huhai Yijian Mixing Station in person according to Captain Liu's request to apologize in person. Although Zhou Yuwei's father knows that his daughter is such a character, he has always wanted to help her change, after all, Zhou Yuwei is twenty-six years old and has not fallen in love, so it is not a way to go on like this. And her iceberg-like personality will also affect her work, after all, who would want to deal with her, her colleagues and subordinates did not conflict with her because of Zhou Yuwei's father's status and face.

Although Zhou Yuwei was reluctant, she had to come to Huhai to build a mixing plant in person at the strong request of her father. Although now she not only does not have the initial disgust for Li Ruoyu, but also has a little affection for him because of his righteousness and bravery, she still can't say anything if she wants her to apologize to Li Ruoyu in front of everyone.

Zhou Yuwei reluctantly showed a smile and said slightly apologetically: "Comrade Li Ruoyu, I'm sorry! Yesterday, in the process of asking you to assist in the investigation of the case, my attitude was very bad! Here, I apologize to you and ask you to forgive me for my mistake!"

Li Ruoyu didn't expect that Zhou Yuwei, an iceberg policewoman, would apologize to herself in person, what was going on? He could see that Zhou Yuwei was a very stubborn person, so how could she suddenly change her attitude? However, Zhou Yuwei's smile made Li Ruoyu and Li Ziqiang a little stunned, and they didn't expect this iceberg policewoman to look so good when she laughed! This is the thought in the hearts of all the people present.

Although Li Ruoyu was stunned by Zhou Yuwei's smile all of a sudden, he didn't show that kind of unhealthy eyes, after all, his soul is a middle-aged man, and his self-control is still very strong. He just stayed on Zhou Yuwei's pretty face for two seconds and then moved away, and his eyes were all a color of appreciation, very pure, an appreciation of beautiful things.

However, the two technicians standing next to him, Yu Tao and Liu Ming were different, when the two of them saw Zhou Yuwei's smile, they felt that there was only this beautiful policewoman left in the whole world, like a beautiful flower blooming, causing the two of them to suddenly turn into a pig brother, and almost didn't let the saliva flow to their chests.

Nie Xiaoqing is a woman, she naturally has a sense of jealousy in her heart for beautiful women, especially this beautiful policewoman, who is so beautiful that she can't eat the fireworks of the world, that smile makes her ashamed of herself, compared with Zhou Yuwei, she is like an ugly duckling in front of a white swan, and a saltless person in front of a fairy.

Li Ruoyu saw Zhou Yuwei's attitude change and apologize in front of so many people, and he was also a little moved, because the police handled cases in this era was originally like this, which is different from the police in the 21st century.
