I am the cook, but I am Li Er's son-in-law

The more he listened to Li Lizhi's words, the light in Li Shimin's eyes became brighter.

Before Li Lizhi continued to introduce, he couldn't wait to ask: "How long will it take to freeze?"

Li Lizhi paused, and was interrupted by Li Shimin, which almost made her breathless, but she had memorized all the information by heart, so she didn't need to look through the experiment records: "In order to ensure its strength, And its shape-shaping ability, the initial condensing time is between half an hour and a quarter to an hour."

"It takes at least five hours to fully condense."

Time is not short.

But Li Shimin was very surprised. He stood up, took the hammer from Qian Niuwei's hand, and smashed it hard at the cement slab.

There was a bang.

There was still only a tiny crack on the stone slab.

The quality is very good.

Li Shimin's mind turned quickly. He knew how precious this thing was. The powder form meant that it was easy to transport, and it could be solidified by adding water and sand, which meant that its production process was not difficult.

Plus the quality after molding.
It's just a pity that Duan Zhixuan had already dispatched ten days ago to attack Tuyuhun with artillery, otherwise, with these things, the marching speed would have been much faster.

"What is the production cost?" Li Shimin asked again.

Li Lizhi tilted her head. This was not within the scope of their experiments. After thinking for a while, she turned her eyes to Li Shu for help.

Li Shu began to explain: "I don't know the exact cost, but... we only used less than one-twentieth of the various minerals we transported back from Brother Zhengyang."

"There is almost no loss in the production of cement powder."

"That is to say, if a total of twenty catties of raw materials are used, the same amount of cement can be produced."

"However. There will be some wear and tear during use, and these losses are negligible compared to the overall volume."

Li Shimin nodded.

That is, there is almost no loss?

This is really great news.

The only problem is whether the ingredients used are cheap or not. Li Shimin doesn't intend to ask his two daughters this question - they are all spoiled, and they think a dish of more than 20 Wen in Tongfu restaurant is cheap.

In terms of price, they are the only ones who cannot listen to them.

Li Shimin didn't ask any more questions.

In just this short moment, he had already had several ideas in his mind about how to use this special material—of course, these ideas were all related to war.

Wait for the next day.

Li Shimin was patient, and after listening to the military report ahead, he couldn't wait to take Wei Zheng, Fang Xuanling and the others to the Tongfu Restaurant.

After entering the room, Fang Xuanling was not in a hurry to order food, but eagerly grabbed Yin Xuan and pushed him across from Li Shimin.

"What's the matter?" Yin Xuan looked at the group of impatient little old men, covered his chest with a serious expression, "I tell you, I am a serious restaurant."

"I am also a decent person."

"I would never do such a thing as selling myself."

Li Shimin waved his hand, now he is not in the mood to joke with Yin Xuan, and cut to the chase: "The store recently taught the little girl how to make cement?"

Yin Xuan nodded, and glanced at a bag of cement behind the counter.

Let's talk about emotion.

These little girls are becoming more and more competitive now. Of course, this is also due to the fact that the family background of the Linlang Pavilion and the Royal family is strong enough, and they have produced results in just one month.

Um.
Of course, the current cement is not the final result, and being usable does not mean that it is the optimal formula, and the properties of the cement that needs to be used are different in different situations, terrains, and environments.

These have to be studied slowly.

However, with a phased result, it is already a matter worth putting on lights and decorations.

Yin Xuan ordered a batch of fireworks from Linlang Pavilion, planning to celebrate tonight.

"I saw this thing last night, and I was surprised." Li Shimin didn't hide his expression, and continued carelessly, "I didn't expect such a thing to exist in the world."

"But after all, it is a new thing from the hands of the shopkeeper. I don't know how the shopkeeper can use it?"

Yin Xuan glanced at him, waved his hands, and said softly: "Since you have seen it and know its nature, you should know that it is excellent for road construction."

Li Shimin nodded.

Last night, the first thing he thought of was building roads.

"Secondly, it is to build a house."

Li Shimin froze for a moment, frowned, and built a house entirely with cement?
this.. will this work?
Yin Xuan went on to say: "It is not easy to build this house now, and some better houses have to use wood, such as my restaurant."

"If you didn't get the wood from the Hu merchants, if you want to build the second floor, you might have to smash in hundreds of sticks to hear a sound."

"After you have cement, you can use bricks and tiles instead, like some girders, you can use wooden strips to pour cement, and if you have the conditions, you can use steel bars to pour cement."

"And this thing, keep warm."

Speaking of which, Yin Xuan's eyes were full of tears from the freezing last winter. The house made of wood was not warm at all. There was no stove or charcoal fire. Within an hour, the house would be completely cold.

A house with a brick-concrete structure is much warmer than a house with a wooden structure.

Li Shimin nodded. This was really something he didn't expect. After all, the war was ahead, and all the things in his mind were related to the war.

People's livelihood was ignored by him.

Yin Xuan paused for a moment, and continued: "And this thing has excellent shaping ability. You are like... something that requires a lot of manpower and material resources. Now make a mold, pour the cement and wait for it to solidify."

I really want to say that apart from building houses and roads, what else can cement be used for?

Yin Xuan really couldn't say anything else.

But the existence of this thing is like air, you can hardly feel its existence, but it is almost everywhere in industrial production.

Li Shimin noticed keenly that what Yin Xuan was talking about was people's livelihood.

This made him look forward to it.

"Then what is the manufacturing cost of this kind of cement?" Li Shimin asked.

Wei Zheng, Fang Xuanling and the others held their breath and looked at Yin Xuan cautiously.

For other things, they still need time to judge whether they are useful or not, but after they heard Li Shimin's description of cement, they thought of a myth and legend.

interest soil.

It has always been a material they have dreamed of.

Yin Xuan shook his head and laughed: "This thing is very cheap, like that limestone, two thousand catties can be exchanged for a glazed cup."

"The clay also costs [-] catties."

"That is to say, it is more laborious to mine now, and the materials are not difficult to find."
