Professor Cheng Jiacheng said as he panted and came to Le Han Dong. He handed a concrete sample in his hand to Han Dong and said, "Han Dong, take a look, this is a sample I took out from the dam of the reservoir, what can you see?" ”

From the very beginning, he called Han Dong by his name, and he did not have any more honorific titles because Han Dong was the deputy director of the National Development and Reform Commission, danshi Han Dong didn't take his title to heart at all, and it can be seen from this that Professor Cheng Jiacheng is a very straightforward person, which is probably one of the factors for his high achievements in academic research.

Cheng Jiacheng looked angry and kept panting.

Han Dong felt that he was afraid that the situation was very serious.

Taking the cement block from Cheng Jiacheng's hand, Han Dong took a serious look at it, this cement block should have been knocked down from the top of the embankment, and it was still wet, presumably from the side of the soaked water.

Feel it by hand, this piece of cement weighs about two catties, one side is smoother, the face is darker, and the other side is a new crack, and if you look closely, you can see that there are some granular small pieces condensed inside. In addition, the darker side of Yan Sè should have been soaked in water for a long time, and it looks relatively smooth, but if you look closely, there are small holes like pinholes.

Looking closely, Han Dong didn't see any obvious DA problems, after all, he was not an expert in this area.

However, looking at Cheng Jiacheng's appearance, the problem must not be ordinarily serious.

Bending down and squatting down, the cement block was placed on the ground, and then Han Dong picked up another pebble and struck it violently on the cement block.

A few clangs left a few marks on the cement block, but it didn't play a role.

Han Dong was a little strange, it seemed that this cement block was very strong, and the force he used just now was not small, and Danshi couldn't smash it.

Standing up, Han Dong asked: "Professor Cheng, forgive me for being a shallow learner, I really can't see any problems with this cement block, you can tell me about it." Cheng Jiacheng was very satisfied with Han Dong's modest attitude, nodded and said: "Just now you also tried le in a normal situation, this cement is very solid, but this is only temporary and superficial, previously they introduced that the company uses the latest cement coagulant provided by Mi Guo Du Milai Company, which can ensure that the cement solidifies quickly, and the strength is very large and can withstand the continuous washing of the waves of the da, so there is no problem at all when used on the embankment." Now here's the problem..............." Han Dong asked duly, "Is this coagulant only effective for a short time?" "Sometimes, asking for advice is the most compliment, the other party is an expert in itself, you don't know how to pretend to understand, it's better to ask honestly to make the other party happy.

Cheng Jiacheng shook his head and said: "That can't be said mainly depending on what environment it is used in, this coagulant should be specially used in the cement in the seawater environment, we are not right to use it here, a little longer, the structure inside will become more and more loose, the entire DA dam is also easy to penetrate, pipe gushing, which is very dangerous, and the DA dam may be destroyed at any time." Han Dong's expression also became solemn, he believed that what Cheng Jiacheng said should be true, after all, Cheng Jiacheng had no need to deceive himself.

"If the cement solidified with this coagulant is used in a seawater environment, then the further reaction between the salts and the chemicals in the coagulant will further promote the hardness of the cement and finally set the shape. At present, the cement solidified by this coagulant in the DA dam can be said to be only a part of the LE, and seawater is also needed to soak it in order to complete the final chemical reaction. Cheng Jiacheng said, picked up the cement block and said to Han Dong: "Look at this side, those small holes on it are the signs of problems with the cement block, and as time goes by, these small holes will become more and more ......."

Han Dong's face became a little ugly, if according to what Cheng Jiacheng said, there are problems with all the cement that uses the coagulant here, then the construction has been doing useless work all the time, and it will be a waste of manpower, material and financial resources.

Seeing Han Dong's extremely dignified expression, Cheng Jiacheng said: "I can use the personality guarantee, there must be a problem with this, the project here should be stopped immediately, and then reworked after investigation, otherwise, there will be problems in the future." Didn't they say that all the coagulants were imported from this company in the United States......"

Han Dong took a deep breath and said, "Of course I believe in Professor Cheng's judgment, so let's do it, Professor Cheng, you eat first, and I will further implement and communicate on this matter, and those who should be reworked will resolutely ask for rework." Cheng Jiacheng nodded and said, "Well, Han Dong, I believe in you, but you still have to hurry." At this time, Xu Shuangyijing walked over with the other three professors, and they saw Han Dong and Cheng Jiacheng's expressions abnormal, and when they asked about it, they knew that there was such a big question, and they were all very angry.

They didn't find out any DA problems before, Danshi's design and structure were all integrated through cement solidification, and now there is a problem with cement, and everything else is in vain.

It can be said that cement is used in almost every part of the construction of reservoirs and dams, so the current situation is very serious.

Han Dong instructed Xu Shuang to take a few professors to eat first, and he himself had to report this matter to the committee.

Hong Jinfeng also stood aside with a heavy face, he had heard all the information just now, just this one problem, the entire hydropower station project was almost abandoned.

Thinking about the whole project, it will take a year or two for the whole project to start, but I am afraid that there will be problems in many places.

"Director Han, I think the construction should be stopped immediately and a team of experts should be organized to conduct a comprehensive inspection, I am worried that the problems in some places are very serious, if something happens during the construction process, it is a matter of human life."

Han Dongshen said with the same feeling: "That's true, in this way, Governor Jinfeng, you immediately report to the province, and I will also communicate with the committee." ”

Hong Jinfeng nodded, and walked to the side, "Go and call."

This time, there is such a big thing as le, but I'm afraid that someone inside will come out to be responsible for le.

"Maybe it's going to be a DA earthquake." Hong Jinfeng thought in his heart as he dialed the phone number of Le Governor Wei Zhongting.

Originally, Hong Jinfeng was still more leaning on Fan Tonghui in the past, after all, Fan Tonghui and Han Dong maintained a good cooperative relationship. Danshi Since the last time Han Dong came to inspect Le, the relationship between Fan Tonghui and Hong Jinfeng has undergone subtle changes, and Hong Jinfeng has also guarded the duty of a vice governor, so if there is any situation, he naturally has to communicate with Governor Wei Zhongting first.

Han Dong took out his mobile phone and directly dialed the mobile phone of Meng Chunde, director of the LE Development and Reform Commission.

The matter is serious and urgent, Han Dong must first ask Meng Chunde for instructions before making the next arrangement, which is what Xian Wei's deputy should do.

"Comrade Han Dong, what's the situation?" Meng Chunde's tone was a little heavy, he received a call from Han Dong, and he knew that there should be a problem, otherwise Han Dong should call the landline number of his office first.

"Director Meng, according to Professor Cheng Jiacheng's judgment, the coagulant provided by the rice country Dumilai company used in the hydropower station, and this coagulant is specially used in the seawater environment, if it is used in the freshwater environment, it will not be able to complete the final shaping work due to the lack of salt chemical reactions, and the cement structure will gradually loose......n after a long time."

Han Dong said a few words, and then explained the situation clearly, "Director Meng, according to Cheng Jiacheng's suggestion, this project must be stopped completely, experts must be organized to conduct a comprehensive verification, and then it is estimated that it will be reversed and restarted." ”

On the other end of the phone, Meng Chunde was silent for a moment, and then said cautiously: "Han Dong, can this question be determined?" I mean, Professor Cheng can be sure? ”

A project with an investment of more than 20 billion yuan has to be reversed, but it is a very big thing, and he can't call the shots. Even if the project is not completed, Danshi's losses will be huge.

Han Dongdao: "Professor Cheng is an expert in concrete research and an authority in China, and just now he used his personality to assure me of his judgment. ”

Meng Chunde knew that although Han Dong was young, Danshi was very steady in doing things, since he said so, the problem was almost certain, and he also listened to Cheng Jiacheng's fame, and knew that he was an old professor with a very good personality, since he used his personality to guarantee Le's affairs, this was much more reliable than the guarantee of most people.

"That's it, Han Dong, you communicate with Xichuan Province now, and I will immediately report this matter to General Manager Chen." Meng Chunde said in a deep voice, such a thing must be reported to the deputy general manager in charge, and then act according to the instructions of the general manager.

Han Dong naturally knew this process, so he said, "Okay, let's keep our noses together at any time." ”

Over there, Hong Jinfeng Yijing reported the oak situation to Wei Zhongting, but Wei Zhongting asked him to report to Fan Tonghui again.

As soon as Hong Jinfeng hung up the phone, Han Dong's phone rang.

Han Dong took out his mobile phone and saw that it was Fan Tonghui calling.

After picking it up, I heard Fan Tonghui say with great sadness: "Comrade Han Dong, the Xichuan Provincial Party Committee is responsible for the problem of LE in the hydropower station project, my suggestion is to stop the work immediately, and then conduct a comprehensive inspection, and track down the relevant responsible persons......"

Fan Tonghui's mood at the moment was extremely depressed, he originally thought that even if some problems were found, it would not be too serious, but now it is such a serious problem, the entire project may need to be counterattacked, and the culprit turned out to be the inconspicuous-looking coagulant.

In addition to the person in charge of the LE project, there must be someone in the province who needs to be responsible for such a big problem.

Even the Xichuan Provincial Party Committee and Provincial Government may have a very big change because of this matter.

Danshi faced such a problem, and Fan Tonghui had no way to change it, so he could only make a high posture and cooperate with the investigation first.

"Comrade Han Dong, Comrade Wei Zhongting and I rushed over immediately, what do you think needs to be done?" Fan Tonghui asked.
