Chapter 1259 There is no industrial mechanization in this era, so what should we do? (Seeking subscription for votes)

It is not far from Luzhou to Jingnan. The trouble is to cross the river, and Luzhou’s wharf is located at the confluence of the Tuojiang River and the Yangtze River.

The river here is relatively open and the flow rate slows down, which is conducive to boating.

When the group of them arrived a few miles away from the cement factory, they could already see the smoke rising in front of them.

Nowadays, a total of seven cement kilns have been completed, and now only three cement kilns are trial-burning cement.

The other four kilns are still in the state of waiting for the rice to be cooked. After all, they have to test out the appropriate ratio before they can officially start producing cement.

Originally, Cheng Chubi wanted to burn red bricks, but soon discovered that the quality of the burned red bricks was really not very good.

In addition, the red bricks are not resistant to freezing or sunlight when placed outdoors, and they are also afraid of moisture.

So that's why red brick houses are usually covered with thick lime inside and out.

It is to prevent the red brick from being damaged by wind, sun and rain.

But the blue brick is different. Although the quality of the blue brick is excellent, there is a problem.

Burning the blue brick is too laborious and time-consuming. The entire kiln must be closed at the later stage of the high-temperature firing stage, and then water will be poured on the top of the kiln to cool down. The kiln can only be opened after five or six days.

It was labor consuming and time consuming, and it was really not suitable for mass and fast production. Therefore, Cheng Chubi hesitated for a few days.

Finally the attention was hit on the solid concrete brick. The so-called solid concrete bricks.

In fact, it is a solid brick manufactured by using fly ash, coal slag, coal gangue, etc. as the main raw materials, using cement as a coagulant, and not being calcined at high temperatures.

As a good person with a very moral bottom line, Cheng Chubi still has a certain sense of environmental protection.

The most important thing is that the cement plant here consumes a large amount of coal every day, cinder after combustion, coal gangue, and some fly ash.

It can be used to make concrete solid bricks. It does not waste the waste after burning, and it can protect the environment. It is definitely a two-way street.

What's important is that solid concrete bricks do not need to be calcined, and can be directly stirred into forming.

As for how to make the ratio, hehe... Then try, I have some money and some raw materials, so I am afraid of being a bird?

After the group of people arrived at the concrete stone, Li Ke looked at the large piece of flat land in front of him, at the huge waterwheels that stood tall on the banks of the Yangtze River.

There are also those three kilns that are emitting thick black smoke at the moment, and there are a large number of workers.

A lot of bamboo is being used to build bamboo buildings for the workers to live in.

Farther away, there are huge black hillsides, and there are coal yards.

"Nowadays, the coal transported from Changning Li is almost half a million catties."

"So many?" Li Ke couldn't help taking a breath, and the horse whip in his hand pointed in the direction of the cement factory and asked.

"Can we consume so much coal here?"

"Hehe, brother Xian, you have been more concerned, let's put it this way, according to the previous calculations of those Ministry of Industry officials, it takes almost 300 catties of coal to burn two thousand catties of mellow soil.

"As for the number of cements to be fired, there are probably two thousand catties of cement, and five hundred catties of coal are needed."

Li Ke didn't understand, but he nodded his head and asked a new question. "How much cement do we need for that mile?"

"Hehe, this, it's too simple..." Cheng Chubi was happy, anyhow, he has an iron buddy who is in the maintenance section.

For these gadgets, I often listen to this stuff squeaky and crookedly bragging, naturally it is very clear.

"Our original official road was only one foot in width. Now I am going to widen the road by one foot and five feet. With cement alone, one mile of road requires about 300,000 catties of cement."

"..." Li Ke's face turned dark, and he said for a long time.

"Brother Chubi, how much cement do we have to burn to finish the road in Luzhou?"

"I don't know, anyway, what needs to be repaired most now is from Jingnan to the dock, and the official road from Jingnan Road to Luozhou."

"As long as this official road can be repaired, so that the well salt in Luozhou will no longer be intermittent due to the chronic disrepair of the official road, we will be a great achievement."

"As long as we have this road as a model, and we can repair other official roads, then we will not only have enough skilled craftsmen.

Moreover, he has experience in building cement official roads. When the time comes, the ten will surely be quick. "

As far as Cheng Chubi knows, the semi-mechanized operation of later generations, a kilometer, a few vehicles, and a construction team of 30 workers, will only take ten days for one kilometer.

Of course that is for later generations. There is no industrial mechanization in this era, so what should we do? Naturally, it only relies on human tactics.

After Cheng Chubi and others arrived, the Ministry of Industry officials stationed here happily came to the ceremony.

"The next official has met His Royal Highness, the long history of the process, and Fang Dianjun.

I waited and worked day and night with a skilled craftsman, but fortunately, I finally made cement that meets the requirements of long history. "

"Has the sample been produced?" Cheng Chubi asked immediately after hearing this.

"Exactly, you Shangguan, please come here."

Cheng Chubi and others followed the Ministry of Industry official to a very level ground. On the ground, there were piles of broken gray-white things like gravel.

Those are naturally the waste after the previous test.

In front of them, there are several cement boards with a length of about three feet and a thickness of about three inches and three minutes.

There are eight stone locks next to them, two hundred catties as big as five, followed by one hundred and fifty catties, one hundred catties, and one each for fifty catties.

The Ministry of Industry official saw the dumbfounded expressions of Li Ke and Fang Jun, and explained with a smile.

"This is a method taught by Cheng Changshi to test the quality of cement. UU Reading www.uukānshu.com"

"We will use the fired cement to mix the concrete and make several cement boards with the same specifications.

Several methods are then used to test whether the quality of the concrete made of cement meets the requirements. "

Of course, these methods were also invented by Cheng Chubi himself, although they were ideas behind closed doors.

But Cheng Chubi felt that he had really tried his best. After all, Lao Tzu is not a professional in architecture. It is already very good to be able to think of a way to test.

For example, one of the cement slabs will be placed above a hollow well built with blue bricks, and then a stone lock will be placed on it to see how much its load-bearing capacity can reach.

Then, place the cement board on a flat ground and place a stone lock on it to see how much weight it will crack.

Anyway, this year, the heaviest thing, I'm afraid it is a bullock cart that can pull two thousand catties.
