The First Family of Tang Dynasty

Hearing what Brother Chubi said, Li Ke couldn't help but don't know what to say.

Cheng Chubi continued to spit out incessantly.

"The so-called hermit is definitely a person who hides in a certain angle and specializes in learning.

As for the masters, they are the highly learned people, and such people don’t even understand why your father moved the capital, hehe…”

Hearing Brother Chubi's remarks, Li Ke had to nod his head in agreement.

"That's right, that's true, but Brother Chubi, if you let them listen to what you said, tsk tsk." It's not far from Luzhou to Jingnan. The trouble is that you have to cross the river, and the wharf in Luzhou is located in The confluence of the Tuojiang River and the Yangtze River.

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

When the group of them arrived a few 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 constructed, and only three cement kilns are currently testing cement.

The other four kilns are still in a state of waiting for the rice to be put into the pot. After all, the production of cement can only be officially started after a suitable ratio has been tested.

Cheng Chubi originally wanted to burn red bricks, but soon found out that the quality of the red bricks produced was really not very good.

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

So this is why red brick houses are generally painted with thick lime inside and out.

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

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

It takes too much effort and time to burn the blue bricks. The whole kiln should be closed in the later stage of the high temperature firing stage, and then watered on the top of the kiln to cool down, and the kiln can be opened after five or six days.

It is labor-intensive and time-consuming, and it is not suitable for mass and rapid production. Therefore, Cheng Chubi hesitated for a few days.

Finally paid attention to the concrete solid brick. So-called concrete solid bricks.

In fact, it is a solid brick made of fly ash, cinder, coal gangue, etc. as the main raw materials, cement as a coagulant, and not calcined at high temperature.

As a good person with a 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, coal **** 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.

Importantly, solid concrete bricks do not need to be calcined, and can be directly stirred to form.

As for how the ratio came about, hehe... Then try it, I have some wealth and silk, and some raw materials, so I'm afraid of a bird?

After the group arrived at the cement stone, Li Ke looked at the large flat ground in front of him, and at the huge waterwheels standing tall on the banks of the Yangtze River.

And the three kilns 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 for the workers to live in.

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

"Now, the coal shipped from Changning is almost 500,000 catties."

"It's so much?" Li Ke couldn't help but gasped, and asked with the whip in his hand pointing in the direction of the cement factory. Gu Hu

"So much coal, can it be consumed here?"

"Hehe, virtuous brother, you are overthinking it. Let's put it this way, according to the previous calculations of those officials of the Ministry of Industry, to burn two thousand catties of mellow soil, it will take about three hundred catties of coal."

"And for cement, there are probably a number of them now. It's almost two thousand catties of cement and five hundred catties of coal."

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

"Hehe, well, that's too simple..." Cheng Chubi was immediately amused, after all, he had a buddy in the maintenance section.

As for these things, it is natural to hear the babble of this guy very clearly.

"Our original official road was only ten feet wide. Now I'm going to build a pavement with a width of ten feet and five feet. It's about 300,000 catties of cement for a mile of cement alone."

"..." Li Ke's face couldn't help but turn dark, and it took a long time to say.

"Brother Chubi, according to your calculations, how much cement do we have to burn to complete the road in Luzhou?"

"I don't know, anyway, what needs to be repaired most now is from Jingnan to the wharf, and the official road from Jingzhou to Nanzhou."

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

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

Moreover, with the experience of building cement official roads, UU reading www.uukanshu.com will definitely be able to do it quickly when the time comes. "

As far as Cheng Chubi knew, the semi-mechanized operation in later generations, one kilometer, a few vehicles, and then a construction team of thirty workers, took ten days for one kilometer.

Of course, that is the future. There is no industrial mechanization in this era, so what should we do? Naturally only rely on crowd tactics.

After Cheng Chubi and others arrived, the Ministry of Industry officials stationed here came excitedly to greet him.

"Xiaguan has met His Highness, Cheng Changshi, and Fang Dianjun.

I waited with a group of craftsmen to work day and night, and fortunately, I finally made the cement that meets the requirements of the long history. "

"Have the samples been made?" 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 flat ground. On the ground, there were piles of broken gray-white things that looked like rubble.

Those are, of course, waste from previous tests.

And in front of them, there are several pieces of cement boards with a length and width 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 in size, five in full, and then one in one hundred fifty catties, one hundred catties, and one fifty catties.

Seeing the confused expressions of Li Ke and Fang Jun, the official of the Ministry of Industry gave a smile and explained.

"This is a method that Cheng Changshi taught us to test the quality of cement."

"We will use the fired cement to mix the concrete, and then make several cement boards of the same size.

The quality of the concrete made from these cements is then tested in several ways. "

Of course, these methods were also thought up by Cheng Chubi himself, although they came up behind closed doors.
