Chapter 254

In general, the amount of gypsum required for cement proportioning is more than 1%, less than 2%.

Making tofu requires less.

In these hills, Zhao Fengnian suddenly felt that a kind of gold was thrown into the field as a lump of earth.

Zhao Fengnian went to Shi Fu, took over the gypsum crystal and looked at it carefully.

Finally, he asked, "is this salt mine the industry of our territory?"

Shi Fu pondered for a while and said with some uncertainty: "this salt mine should be a territory industry, right? If it dries up after rain, salt will appear on the surface of the ore bed. At that time, the territory will organize personnel to collect it. After taking away the required quantity, the rest will be owned by the territory. "

Zhao Fengnian nodded and felt relieved. Fortunately, this place is his own industry.

However, there may not be much profit in a year, so there is no record.

"Mr. Shi, do you know why I am so nervous about this place?"

Zhao Fengnian had no reason to ask suddenly.

Shi Fu's face was full of doubts: "little Lord, villains don't know, but please don't worry about it."

Zhao Fengnian put the gypsum mine back into Shi Fu's hands and laughed.

"I always thought that if the cement didn't succeed, there must be something missing, but I didn't think of it. Until you see it... "

"What!? Little Lord, what you said is If this thing is added to the cement, it can solve the problem of rapid setting? "

Hearing Zhao Fengnian say this, Shi Fu can't help but get excited, and his voice is shaking.

Zhao Fengnian nodded and said, "it should be like this, Li Xuanwu. You should wrap some plaster with cloth bag. In addition, Mr. Li, the gypsum here will be moved to the warehouse as soon as possible. If this is the case, the gypsum will be of great use! "

"Yes, little Lord!"

Later, they rushed back to the kiln where Shi Fu stayed before.

First, the gypsum is ground into powder, and then added to the cement according to the proportion provided by Zhao Fengnian.

After that is the same step as before, mixing sand and stone, pouring water and stirring.

After pouring water and stirring, although the mixture absorbs some moisture, most of the water is between small particles.

Although the mixture in the wooden box was thick, it did not solidify directly as before.

After that, Shi Fu used a small flat shovel to pick out a part of the mixture and spread it directly onto a green brick.

The rest of the time was waiting. It took more than 40 minutes for the mixture in the box to solidify and not stir.

The mixture on the green brick is also adhered to the green brick. Although there will be fingerprints when you press it down, the mixture will not fall down naturally when the green brick is erected.

It's done! Seeing this scene, Zhao Fengnian knew that cement research had been successful, and the rest was to wait more than ten hours to verify the final results.

Shi Fu was also very excited to see this scene. Sure enough, there was nothing that the little Lord could not do.

This new material is a rare treasure for the earth rock craftsman like him. With it, the work efficiency will be greatly improved, and some theoretical buildings can be completed by using cement.

"Well, the rest is to see the effect tomorrow. Mr. Shi, remember that this formula can only be mastered by you and the old people trusted by the territory. You can directly provide the matched materials and ask the workers to cook them. "

"In addition, cement needs to be manufactured in large quantities. Are there any difficulties that need to be solved? I'm here, and I'll give you a solution."

Seeing the success of the experiment, Zhao Fengnian was concerned about the production.
