Chapter 23 Reinforced Concrete Walls

After sleeping until dawn, it is really troublesome to have nothing to eat after waking up. Zhu Changyuan scratched his head and felt that it would be better to deliver some things as soon as possible, especially food. You can’t eat one meal a day, and you are always hungry.

Outside, Li San had already led his scout squad to set off for patrol. The four captains were in full swing and started digging the foundation pit of the city wall with shovels. At this speed, it is estimated that the east wall and south wall.

Zhu Changyuan couldn't help being troubled. A foundation pit is about 100 meters long. Calculated according to the cubic volume, it is about [-] cubic meters of concrete. Don't worry about sand, stones and water, there are ready-made ones here.Shutdown is cement.

Zhu Changyuan is a student who graduated from the Civil Engineering College. He knows a rough ratio. About [-] kilograms of cement is needed for a square of concrete, and about [-] tons for a thousand square meters. When all four city walls are built, it will be [-] tons. Just the basic amount.

Calculated according to the carriage, because the quality of the cement is relatively large, at the limit, it can only pull ten tons at a time. That is to say, it will take 120 days to pull [-] tons of cement, which is still nothing. Only pull the cement case.

No, it has to be a new way.

Looking at the glittering items on the system interface, Zhu Changyuan suddenly thought that the previous skill books can be purchased unlimitedly. I wonder if this carriage and trolley can also be purchased many times?
With this idea, Zhu Changyuan was excited, if he could buy ten carriages at once, hehe. . .

He rushed to the tent without thinking about washing his face and brushing his teeth, first entered the system interface, clicked on the item column, and got out the column of the carriage.

Click on the icon, it shows that the purchase will cost [-] contribution points, do you want to buy it?

buy.

"Ding, the purchase was successful."

I wipe, is this really okay?

Summon the two carriages at the same time and put them in the tent, almost exactly the same.

Buy buy buy buy. . .

Zhu Changyuan kept clicking, and bought nine carriages in an instant, including the one he had before, exactly ten.

Ten horse-drawn carriages must not be let go in the big tent. After all the purchases, they were not summoned immediately, but stayed in the system. Now, there is no need to worry about the problem of being unable to transport them all. What is the key is yourself Get tired.

One person carried all the ten carts of things. Although the strength is huge now, it can be imagined that this is also an unimaginable physical work. The key is to save time.

Click to return to the original world, pull out the map, and choose the place to go.Click, the eyes go dark, and then the head buzzes, and the feeling of dizziness comes.

Opening his eyes, it was bright. He was already standing next to the warehouse of the meat joint factory he rented. He took out the key and opened the door. There was already a pile of cement inside. It seemed that Liu Guang was not lazy yesterday.

Pull all ten wagons out of the system and start loading cement.

Due to the increase in strength, it was much easier to carry. The first carriage of cement was loaded in less than 10 minutes, which was as much as ten tons.

Filled with ten tons, it almost looks like a hill has been piled up on the carriage.

There is not much cement left, and Zhu Changyuan still has nine cars, so the remaining cars are not particularly full. A total of about fifty tons of cement is divided into nine cars.It doesn't look so weird anymore.

After the cement was filled, Zhu Changyuan roughly checked the time, and it took about half an hour.There is still a car left, and it cannot be left idle for no reason. I took out some rice and carrots in another smaller warehouse, and went to a nearby supermarket to buy more than 200 catties of pork to put on the carriage. There are some scattered household items.

He drove all ten carriages to the yard of the warehouse, took out his mobile phone and sent Liu Guang another text message: The large warehouse still needs [-] tons of cement and [-] tons of steel bars, and the small warehouse needs to pile up rice every day.

The specific steel bar models were also annotated to Liu Guang.

Then, with his ten carriages, he disappeared into this world.

Zhu Changyuan pulled all the things back, put the carriage into his big tent, and only called Ma Hai and Polu to come in to carry it.Although the people outside are all his subordinates, but when it comes to cronies, so far only these two will not betray him or tell his secrets.

After carrying fifty tons of cement, the three of them were exhausted and out of breath.

During this transfer, I also saw the lack of strength of the two. Zhu Changyuan was not stingy, and spent 18 contribution points in exchange for [-] basic fighting skill books for the two of them. Each of them ate nine books, plus The previous ones just happened to become the same enemy as himself.

Now, with two Guan Yu and Zhang Fei under his command, isn't he the same Liu Bei back then.Ha ha.

Zhu Changyuan's heart suddenly burst out with pride, but when he looked at the remaining [-] contribution points on the system interface, he suddenly became anxious again. The contribution points are spent too quickly.It is too fast.

Put all the ten carriages into the system, then walked out of the big tent, looked at the busy people, smiled slightly, and said: "The captain and the second captain come here."

Yan Hong and Sun Erlent ran over quickly.

Zhu Changyuan said: "According to the locals, there are cobblestones in the Daling River near here. Your two brigades have been going to get out the cobblestones since this afternoon. Do you understand what I mean? Don't want big ones that are bigger than your fists, just small ones." ,Understand?"

"clear..."

"However, we don't need this kind of cobblestones to build the city!" Yan Hong asked suspiciously.

"I said you can use it when you need it. You just need to transport it. The more you can transport, the better. Have I forgotten all my requirements for you? Soldiers take it as their bounden duty to obey orders, just execute them, don't ask."

"Yes, my subordinate understands."

Theoretically speaking, it is unqualified to use pebbles instead of stones to make concrete aggregates. This is some professional theoretical knowledge, and it is impossible to explain it to bastards like Yan Hong and Sun Erleng.

Anyway, pebbles are forbidden to be used as concrete materials on the construction site, but there are no such perfect stones in this world, and the stones are all made by crushers.There is no crusher here, and even if the crusher is brought in, there will be no electricity, so pebbles can only be used instead.

However, having said that, cobblestones are not so bad that they cannot be used. Many projects that cut corners are actually made of cobblestones, but the strength of the concrete behind it is weaker after it ages.But in this world, enough is enough, it is better than those walls made of mud and sand.
