The sand pile is on the edge of the farmland next to the dam, just down the slope.

Glancing at the remaining materials, Shen Yu frowned. Then ask Li Hao to demonstrate the whole process of mixing.

"Your Highness is the dam that is infused with this?"

"That's right! The main palace first placed the steel frame in the center, then built the walls on all sides, and then poured this slurry. Finally, the wall was covered with this slurry, and the dam was built. Tell me about it, where is the business trip? ”

"His Royal Highness's meaning Shen Yu understands that His Highness wants to use steel bars to make the skeleton of this slurry, which is theoretically correct, but the difference is in technology. First of all, His Highness did not lay the foundation, and secondly, His Highness confused the true purpose of this concrete. ”

“？？？”

Li Hao was indeed negligent about the foundation, but he really couldn't figure it out when he didn't understand the purpose of the concrete.

If you want to make a wall in the water, what else can you use without this material? Do you want to put a boulder in the river and stick it with it?

"Purpose? This thing doesn't use it like this, how else can it be used, why didn't this palace understand? ”

"In fact, this slurry made by His Highness is a kind of adhesive, and it has no skeleton itself, and after it dries, it will break when it is knocked out. If you add meridians to it, it's different. It's hard to break it. ”

"Meridians? What? ”

"River pebbles! If you don't believe it, let's give it a try. ”

“……”

According to what Shen Yu said, Li Hao immediately ordered someone to pick up a pot of river pebbles of similar size and add them to the slurry.

"After doing it, Your Highness will see the effect, it must be as strong as a stone mountain."

Actually, Li Hao doesn't need to look at the effect, and Li Hao knows that what Shen Yu said is right. Because he remembered the people building houses and mixing straw with yellow mud.

Isn't that the same as that?

After the skeleton matter was solved, Shen Yu talked about the problem of steel bars again.

She suggested that Li Hao put a ring on the basis of the original frame, so as to solve the problem of iron bar welding. Moreover, it is said that in addition to welding, steel wires should be tied to the welding, so that the double insurance will not collapse.

As for the problem of cracking the outer covering, Shen Yu also has a unique opinion. She suggested that Li Hao add gypsum powder to the Sanhe ash. It is also said that the cracking problem is caused by a variety of reasons. Perhaps the sand is too fine, the ratio of various raw materials is improper, or it may be caused by improper maintenance. It is recommended that Li Hao switch to medium sand, not sand and ash. Do not expose your face to the sun and spray some water if necessary.

After Shen Yu finished speaking, Li Hao was simply shocked. How can Shen Yu understand something that the Ministry of Industry doesn't understand?

In fact, there are some things that Shen Yu doesn't understand, she only knows about it after reading a letter.

In the evening three days ago, when Li Hao went to the Western Regions to look for steel powder, Shen Yu was bored and went to Chongwen Hall to find some civil construction books to read.

If you want to build a dam, you have to find a material that can withstand blisters. As a result, Shen Yu also had the idea of mixing volcanic ash with sediment.

Finally, she found what she was looking for in a book. So, according to what was written in the book, Shen Yu found Bai Qizhi and a few other people who liked to study it.

Verification requires practice, but there are no relevant materials in the palace, so a few people give up.

Shen Yu is a person who can't sleep if he can't figure it out, and when he returned to the Lizheng Palace, Shen Yu grinded the stones with the palace maids. After getting some stone powder, he found materials such as fine sand, and Shen Yu combined them together. Early the next morning, Shen Yu really got the verification, and this mixture was as hard as a stone.

The problem of the material was solved, but then the problem came.

Although the substance is hard, it is fragile and breaks when smashed. The dam can't tolerate a single crack, so how can we solve the problem of brittleness?

So, Shen Yu thought of the civil construction personnel of the Ministry of Engineering. Li Hao is here, it's a matter of minutes to see anyone, Li Hao is not there, she is a princess to be married without a name, what right does she have to see the minister?

Tossed and turned, and the matter was learned by Fu Mingxuan's eyeliner.

What kind of existence is Shen Yu in Fu Mingxuan's eyes? What she wants to do, Fu Mingxuan has to satisfy her by demolishing the house and selling the land.

So, Fu Mingxuan studied this kind of concrete.

Fu Mingxuan was well-connected and knowledgeable, and it didn't take long for him to study this substance thoroughly.

Then, an unsigned secret letter was passed to Shen Yu.

The arrival of this letter really made Shen Yu excited. Excitement is excitement, you have to know who it is, right?

The handwriting is not unfamiliar, but Shen Yu just can't remember who wrote it.

Who's helping her? What does it mean to write that poem?

Puzzled, Shen Yu carefully read the poem under the letter.

I can't sleep at night, sit up and play the piano.

The thin curtain shows the bright moon, and the breeze blows me.

The outfield of the Lone Hong, the birds singing in the north forest.

What will you see when you wander? Worry and sadness.

Shen Yu understood the meaning, but she didn't understand why this person conveyed sadness to her.

Could it be that this person knows her well?

After reading it a few more times, Shen Yu didn't remember who the handwriting in the letter came from.

"What are you thinking, so focused?" After saying a few words, without seeing Shen Yu's reaction, Li Hao moved Shen Yu's shoulders around.

"Your Highness, I want to go to my uncle's house to have a look."

Speaking of Shen Chenye, Li Hao was taken aback, thinking that Shen Yu remembered something.

"Oops, that's not a coincidence. Shen Zhongshu went out on an errand and went to Luoyang this morning. ”

"He went to Luoyang, isn't his aunt still in the house?"

"Your aunt has been gone to the countryside to recuperate, and she has been gone for months."

"Then I'll go to the countryside to find her."

"Thousands of miles, how to go? Shen Zhongshu will come back in a few days, and this palace will accompany you to Ha. ”

coaxed for a while, but Shen Yu was coaxed into the carriage.

The two got into the carriage, and Fu Mingxuan also put down the clairvoyant mirror. It turned out that he was watching Shen Yu from a high place all the time.

Since bidding farewell to the East Palace, Fu Mingxuan has been thinking about Shen Yu all the time. It's like that poem, but it tortures him.

At this time, he was looking forward to Shen Yu going to Daxiangguo Temple tomorrow to make incense.

As long as the plan is successful, he will take Shen Yu away and fly away, so that Li Hao will never find her again.

"Yu'er, wait one more day, wait one more day, and our husband and wife can be reunited."

"Sir, there's a letter from Zhengzhou."

Just when Fu Mingxuan was silently expecting the carriage, his cronies handed over an extremely small and delicate bamboo tube.

The small bamboo tube is specially tied to the leg of the carrier pigeon to transmit information. Although Fu Mingxuan thought that Shen Yu was crazy, it did not mean that his will was decadent, and he was still very concerned about the major events in the world.

Realizing that it was Li He's news, Fu Mingxuan hurriedly opened the small bamboo tube and took out the letterhead.

Seeing this, Fu Mingxuan couldn't help but be overjoyed.

"Go and fetch the 'Winding Beam' for Benjue, and Benjue will play it well."
