It's not far from Luzhou to Jingnan. The trouble is crossing the river, and the dock in Luzhou is located at the intersection of the Tuojiang River and the Yangtze River.
The river surface here is relatively open and the flow speed is slow, which is convenient for boating.
By the time the group of them arrived, which was still several miles away from the cement factory, they could already see the rising smoke in front of them.
At present, a total of seven cement kilns have been completed, and only three cement kilns are currently trial-burning cement.
The other four kilns are still waiting for the rice to be put into the pot. After all, they have to test out a suitable ratio before they can officially start producing cement.
Originally, Cheng Chubi wanted to bake red bricks, but he soon discovered that the quality of the fired red bricks was really not that good.
Moreover, red bricks are not resistant to freezing or sunlight when placed outdoors, and they are also afraid of moisture.
So this is why red brick houses are usually painted with thick plaster both inside and outside.
This is to prevent the red bricks from being damaged by wind, sun and rain.
But things like blue bricks are different. Although the quality of blue bricks is excellent, there is a problem.
Firing the green bricks is too labor-intensive and time-consuming. At the end of the high-temperature firing stage, the whole kiln must be closed, and then water should 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-intensive and time-consuming, and it was really not suitable for mass and rapid production. Therefore, Cheng Chubi hesitated for a few days.
Finally, I paid attention to concrete solid bricks. So-called concrete solid bricks.
In fact, it is a solid brick made by using fly ash, cinder, coal gangue, etc. as the main raw materials, using cement as the coagulant, and without high-temperature calcination.
As a good person with a very moral bottom line, Cheng Chubi still has a certain awareness of environmental protection.
The most important thing is that the cement plants here consume a large amount of coal every day, including coal residue after combustion, coal gangue, and some fly ash.
It can be used to make concrete solid bricks. It does not waste these waste materials after burning, but also protects the environment. It is absolutely convenient for both sides.
The important thing is that solid concrete bricks do not need to be calcined and can be directly mixed and shaped.
As for how to come up with the ratio, haha... let's try it. I have plenty of money and raw materials, so I'm afraid of a bird?

After the group arrived at the cement stone, Li Ke looked at the large piece of flat land in front of them and at the huge waterwheels that stood tall on the bank of the Yangtze River.
There are also those three kilns that are spewing thick black smoke at the moment, and there are a large number of workers.
A large amount of bamboo is being used to build bamboo buildings one after another for the workers to live in.
Further away, there are huge black hillsides, where are the coal dumps.
"Today, the coal transported by Changning is almost half a million kilograms."
"Are there so many?" Li Ke couldn't help but take a breath of cold air, and pointed the riding crop in the direction of the cement factory and asked.
"Can this much coal be consumed here?"
"Haha, dear brother, you are worrying too much. Let's put it this way. According to previous calculations by those officials from the Ministry of Works, it takes almost three hundred kilograms of coal to burn two thousand kilograms of cooked soil."
"As for cement burning, there is probably a quantity now. It is almost two thousand kilograms of cement and five hundred kilograms of coal."
Li Ke didn't understand, but he nodded casually and asked a new question. "How much cement do we need for that mile of road?"
"Haha, well, that's too simple..." Cheng Chubi was immediately happy. At least he had a good buddy in the maintenance section.
Regarding these things, I often hear this guy bragging, so I naturally know it very well.
"Our original official road was only one foot wide. Now I plan to build a road that is ten and a half feet wide. In terms of cement alone, one mile of road will require about 150,000 to 60,000 kilograms of cement."
"..." Li Ke's face turned dark and he said after a long time.
"Brother Chu Bi, according to your calculation, how much cement do we have to burn to complete the road construction in Luzhou?"
"I didn't know. Anyway, what needs to be repaired most right now is the official road from Jingnan to the dock, and the official road from Jingnan to Chuizhou."
"As long as this official road can be repaired so that the well salt production in Cuizhou will no longer be intermittent due to the disrepair of the official road, we will have done a great job."
"As long as we have this road as a model and build other official roads, we will not only have enough skilled craftsmen.
And with the experience of building cement official roads, it will definitely be very fast when the time comes."
As far as Cheng Chubi knew, in later semi-mechanized operations, one kilometer required several vehicles and a construction team of thirty workers, and it only took ten days to complete one kilometer.
Of course, that was in later generations. There was no industrial mechanization in this era, so what should we do? Naturally, we only relied on the human sea tactic.

After Cheng Chubi and others arrived, the officials from the Ministry of Works stationed here came excitedly to pay their respects.
"I have met His Highness, Cheng Changshi, and Fang Dianjun.
After working day and night these days, I and a team of craftsmen, fortunately, have succeeded in producing cement that meets Chang Shi's requirements."
"Have the samples been produced?" Cheng Chubi heard this and asked immediately.
"Exactly, sirs, please come this way."
Cheng Chubi and others followed the Ministry of Industry official to a very flat ground. On the ground, there were piles of broken gray-white things that looked like gravel.
Those are naturally the waste from previous tests.
In front of them, there were several cement boards with a length and width of about three feet and a thickness of about three inches and three inches.
Next to it are eight stone locks, five of which are two hundred kilograms in size, followed by one each of one hundred and fifty kilograms, one hundred kilograms, and fifty kilograms.
The official from the Ministry of Industry saw the confused expressions of Li Ke and Fang Jun, smiled and bowed before explaining.
"This is a method taught to us by Cheng Changshi to test the quality of cement."
“We will use the fired cement to mix the concrete and then make several cement boards with the same specifications.
Then several methods are used to test whether the quality of concrete made from these cements meets the requirements."
Of course, these methods were also thought up by Cheng Chubi himself, although they were ideas developed behind closed doors.
But Cheng Chubi felt that he had really tried his best. After all, I am not a professional in construction. It was already good to be able to think of a way to test it.
For example, one of the cement boards will be placed on top of a hollow well made of blue bricks, and then a stone lock will be placed on top to see how much load it can bear.
Then, place the cement board on a flat ground, place stone locks on it, and see how much weight it takes for it to crack.
Anyway, these days, the heaviest thing is probably an ox cart that can pull two thousand kilograms.
