Chu Jianghe knows very well that if he does construction, if he works decently, he can indeed make money, but he can't make a lot of money. Pen "Fun" Pavilion www.biquge.info

Don't look at the investment of more than 300,000 yuan in this cement road, if all of it is done according to the budget on the design, Chu Jianghe really can't make a lot of money.

Therefore, he must be deducted in some aspects in order to make money, these means, in the next twenty years, are not a secret, and with the progress of the times, the means of engineering are also different, the so-called policy, there are countermeasures, this is the meaning.

And the place where the most money is likely to be saved, and the place where the most money is saved, is undoubtedly the raw materials, cement, sand, and stones.

Needless to say, the price of cement from different manufacturers is different, and it is normal for each package to differ by one or two cents, plus the amount needed by Chujianghe is also a lot, and it can be cheaper. The most important thing is that the town does not require what kind of cement must be used, so Zhao Guodong can't talk too much about cement.

Cement Zhao Guodong is not easy to speak, sand and stones, Zhao Guodong can say, it is obvious that in the information of this cement road, the proportion of Shahe stones has been indicated, as long as people who understand the project look at it, they will know that there is more sand and less stones.

"Brother Zhao, is there anything special about this thing?" Chu Jianghe asked with a bewildered expression.

At this time, you must not do the same thing that you know very well, if you know that this will not work and still do it, isn't this not giving Zhao Guodong face?

Zhao Guodong saw that Chu Jianghe didn't look like he didn't know how to pretend to understand, plus Zhao Guodong's understanding of Chu Jianghe, Zhao Guodong only defined Chu Jianghe in his heart, because of the relationship between Chu Jianjian, he took this job, and it was very likely that he didn't know anything about construction.

However, Chu Jianghe ignored a key point, that is, Chu Jianghe's arrangement of various tasks, from the initial leveling of the site, to the erection of formwork and the current pouring of concrete, Chu Jianghe showed things that did not look like a layman.

Zhao Guodong couldn't pay attention for a while, I don't know if this Chu Jianghe really doesn't understand or fake, but since Chu Jianghe asked, Zhao Guodong didn't say one, two, three, it must not work, even if you are a supervisor, if you don't give a reason why you can't do this construction, people won't be convinced.

"Boss Chu, in the information of this cement road, there is a very important thing, that is, the mix ratio of concrete, I don't know if you have heard of it?" Zhao Guodong paused and decided to start explaining from the source.

"Concrete mix ratio?" Chu Jianghe heard this, looked at Zhao Guodong with a puzzled look on his face, and said curiously: "What is this?"

In fact, in the heart of Chujianghe, I know the mix ratio of concrete clearly, and I know very well that the concrete strength of this cement road is C20.

As the name suggests, the mix ratio of concrete is the ratio of cement, sand, gravel and water in concrete.

The mix ratio of each model, the amount of various raw materials added, are very particular, like the C10, C15, C20, C30, C35, C40 concrete on the market, refers to the strength of concrete, the corresponding mix ratio is also different, C40 concrete, in these concrete, the highest strength.

Later, there was also C50 and other high-strength concrete, but the place where it is used is relatively small, even in the era of high-speed rail, C50 concrete is only used in the pad stone and beam body, pier body, bearing cap and other places with C50 concrete, the main reason is that the price of C50 concrete is too high.

In the concrete mixture, cement plays the greatest role, the stronger the concrete, the more cement must be used, and it is also some good cement.

Zhao Guodong saw Chu Jianghe's confused look, and sighed slightly, he felt that he seemed to be looking too highly at Chu Jianghe, maybe Chu Jianghe really didn't understand this aspect.

And the reason why Zhao Guodong understands these is because when Zhao Guodong was young, a young man in the town was a national engineer, and when the other party went to the countryside, he brought a lot of engineering books and a lot of construction specifications.

Zhao Guodong has loved learning since he was a child, and he understands all of these, and often asks the educated youth for advice.

In seventy-nine years, the educated youth left Chujiang Town, but Zhao Guodong already knew a lot about engineering, plus he worked in the town government, so he was sent to be the supervisor of this cement road this time.

"The so-called concrete mix ratio, to put it bluntly, is the ratio of cement, sand and stone, such as this C20 concrete, according to the design requirements, the ratio of cement: sand: stone is 1:2.23:3.07. In other words, 100 catties of cement require 223 catties of sand and 307 catties of stones. Zhao Guodong explained for Chu Jianghe.

When Chu Jianghe heard this, he secretly said in his heart:, could it be that this guy has done engineering before? Otherwise, why is the coordination ratio explained so simply and clearly.

Of course, Zhao Guodong didn't say anything about water, in fact, in Zhao Guodong's view, water is irrelevant, but Chujianghe is very clear that there is an important indicator of concrete, that is, slump, this indicator is closely related to the amount of water added.

Too much water produces segregation of concrete, that is, sand is sand, stone is stone, cement slurry is cement slurry, three raw materials, can not really be mixed together, this situation has a great impact on the strength of concrete. And if there is less water, stirring is not ingredient, which is another problem.

Therefore, in the concrete mixture, the requirements for adding water are also very strict.

When Chu Jianghe heard this, he suddenly brightened up and said, "I have never heard of this project before." ”

"Of course, I learned all this knowledge from an old engineer. Seeing Chu Jianghe's look of adoration, Zhao Guodong said proudly.

As soon as Chu Jianghe heard this, he knew why Zhao Guodong understood all this, the older generation who could be called engineers in the fifties and sixties, their knowledge and ability were completely incomparable to those engineers in the 21st century.

You know, in the past eight years, the drawings designed by the design institute are all hand-drawn, which is like later, all with computers, drawing CAD and then printing, there is no such situation, all the design drawings, elevation, linearity and other materials, are drawn by hand.

So, Chu Jianghe really admires the engineers of the fifties, sixties and seventies, you don't have a few brushes, you want to engage in design, get the ball, do you really think it's the 21st century, it's a place where everyone can enter?

"Brother Zhao, I can't use a rod to weigh this, besides, it's too inconvenient to use a scale. Chu Jianghe said with a sad face.

"Boss Chu, I also understand your feelings, it's really unrealistic to weigh a little bit, I think, you mix a bag of cement, use four loads of sand from a bamboo dustpan, plus six loads of stones, so it's okay. Zhao Guodong pondered for a moment and proposed.

"Okay, since Brother Zhao said it, then after I go back tonight, I will find my four people who lead workers and teach them a good lesson. Chu Jianghe didn't hesitate, since Zhao Guodong said so, then just do it.

"Well, you can do it yourself. Zhao Guodong nodded slightly.

In the evening, Chu Jianghe called the second dog and said to Zhao Guodong: "Brother Zhao, go, take my car and I'll send you back, and invite you to have a meal in the evening." ”

Although Zhao Guodong is from Chujiang Town, he can't afford to buy a bicycle, and when he comes to the construction site in the morning, he walks to the site.

"No, no, I'll walk back by myself, and as for eating, I'll go home and eat." Zhao Guodong hurriedly waved his hand and refused.

When he was about to get off work, Zhao Guodong had already told Chu Jianghe that he would not eat here in Chu Jianghe and would eat at home.

"What about this, the first time we meet today, I have to invite you to a meal, after all, we have many aspects in the future, and we need to cooperate and communicate. Chu Jianghe didn't give way.

"That's it, Brother Zhao, we have to cooperate well in the future, isn't it just a meal. The second dog also said on the side.

"Let's go, let's go, I'll ride you. Chu Jianghe said with a smile.

Subsequently, regardless of whether Zhao Guodong agreed or not, he went to help his bicycle, and Ergouzi also went to ride his bicycle.

"Brother Zhao, come up, I'll take you. Chu Jianghe stepped on the pedal with one foot, and said to Zhao Guodong with one foot on the ground.

Seeing this, Zhao Guodong couldn't refuse, so he had to sit in the back seat of Chu Jianghe, Chu Jianghe shouted, and said, "It's done, I'm leaving." ”

"Boss, wait for me. Behind, the second dog struggled to catch up with the bicycle.

Chujiang Town is not small, but there are not many places to eat, and each one is not cheap.

Chu Jianghe is quite familiar with Chujiang Town, and found one of them, and after the two dogs locked the car, he stepped forward and opened the door to Zhao Guodong and said, "Brother Zhao, please inside." ”

"Boss, ask for a private room. "The Chu River channel.

"Howler. ”

In the end, the three of them asked for a small private room and an electric fan, but it was not hot at all in the room.

"Brother Zhao, let's order a few dishes. Chu Jianghe handed the menu to Zhao Guodong.

"Come on, Jianghe, I can eat anything. Zhao Guodong hurriedly excused himself.

To tell the truth, Zhao Guodong is just an ordinary civil servant in the town, and he rarely has the opportunity to go out to eat, and even if he has the opportunity to go out, he serves the leader, and it is not his turn to order food.

Therefore, when Chu Jianghe asked him to order, Zhao Guodong felt very awkward, because he didn't know what to order, so it was better to let Chu Jianghe order it.

In the end, Chu Jianghe ordered five dishes and one soup, and said to Zhao Guodong, "Brother Zhao, what kind of wine are you drinking?"

Anyway, it's not driving, and there is no investigation for drunk driving, and Chu Jianghe is not worried about being investigated for drinking and cycling.

"If you don't drink, you can just eat. Zhao Guodong hurriedly said.

"Brother Zhao, why don't you have two bottles of beer, why don't you eat and drink. "The Chu River channel.

"That's it, Brother Zhao, let's have two bottles of beer. The second dog was also busy.

"Jianghe, you can do it. Zhao Guodong had no choice but to say so.

"Okay, then I'll go out and have a look, there is beer, and you can chat with Brother Zhao for a while. Chu Jianghe said, got up and walked out.

Chu Jianghe went out of the room, of course he didn't want beer, there are only two kinds in this beer shop, what else to choose?
