Chapter 248

After that, Shifu added a proper amount of water. As soon as the water touched the mixture of sand and powder, it was quickly absorbed by the mixture.

As Shifu is stirred evenly, the mixture in the whole wooden box is kneaded into a ball, and the color turns black and gray.

Zhao Fengnian saw here, a little surprised, this is not a success? I don't think it's different from the cement I saw in the last life.

However, with Shi Fu's explanation, the mixture gradually becomes thick and hard.

Until a few minutes later, the mixture in the box had completely solidified together, and the sticks that had stirred the mixture had solidified in it and could not be pulled out.

"Little Lord, that's it. Until a few hours later, the mixture will become extremely hard, like a stone. But after that, the stone will crack, and it can't meet the standard of the little master

Shi Fu finished the demonstration and said in frustration.

Zhao Fengnian nodded and looked at the mass, which was not different from the cement of Zhao Fengnian's previous life.

It's just that it's too fast to be used in construction. It turns into a hard lump, which is not practical at all.

There are also serious cracking problems It must be that you have ignored that step, so this situation will appear.

Zhao Fengnian saw the color of thinking. He reached for the wooden box and pressed the initial solidified mixture with his hand.

It was found that although it was solidified and viscous, it could still move by pressing, and a small pit appeared when the finger was pressed down.

How to delay the setting time of cement? Zhao Fengnian thought hard and tried to search all kinds of memories about cement from his memory.

However, after a long time of hard thinking, Zhao Fengnian still has no clue. He really can't think of it. Zhao Fengnian decides to put this matter down first and go for a walk elsewhere.

"Mr. Shi, I'll think about it slowly. It seems that your research is OK. The cement has been generally successful. Your hard work is not in vain. "

Hearing Zhao Fengnian's words, Shi Fu thought it was Zhao Fengnian's consolation to him. He was greatly moved: "thank you, little Lord! I will think of a way to deal with this problem as soon as possible! "

Zhao Fengnian nodded, looked around and said to Shi Fu, "come on, show me around. I haven't been here since the completion of the project."

Seeing that Zhao Fengnian wanted to visit here, Shi Fu led Zhao Fengnian to visit.

The main task of this workshop is to make bricks and tiles. There are dwellings, canteens, four large warehouses and five kilns for firing bricks and tiles.

In this world, such a large-scale workshop is rare. Even in the south where the workshop industry is developed, there are not many workshops of such scale.

There are more than 200 people working in the workshop, together with the fishing village staff. Most of them are old craftsmen selected from the immigrants.

Because the work is not heavy, but also requires patience and experience, these old craftsmen can be said to make full use of them.

First of all, Shi Fu took Zhao Fengnian to visit several kilns. At this time, two kilns were firing bricks and tiles, and three were temporarily vacant.

One by one workshop workers were working on embryo making and drying indoors. Looking at the people who were dedicated to their work, Zhao Fengnian told Shi Fu not to disturb him, so he continued to set out for the next station.

After seeing all the kilns, Zhao Fengnian knew that one kiln could produce more than 3000 bricks, which took about three or four days.

Now, because the land is not civilized and the materials are rare, only two furnaces can be opened at a time.
