Shi Lezhang was the first to speak, "This is the one you said, made of cement that works much better than lime mortar?" ”

Zhong Shuyu: "Exactly, such a cement floor is paved with cement and sand. ”

Shi Lezhang stepped on it with his feet, squatted down and touched it with his hands, and exclaimed, "You really made it!" ”

"This effect is so good, it can be solidified so hard?"

"Even if the lime mortar is mixed with egg whites and glutinous rice juice, it can't reach this level of hardness."

"And it can be used on the ground."

In the middle of Shi Lezhang's chatter, Wang Yuankui also squatted towards the concrete floor with a shock. ✮wap.feng✰s✦hu❊g✩fo

Shi Lezhang glanced at it in amazement, turned his head to Zhong Shuyu and asked, "How long does it take for this cement to solidify?" ”

"Depending on the weather, if it's summer, it only takes a few hours, and in winter, it needs to be extended, and of course, if it's just applied between two bricks, it usually only takes a few hours to completely solidify."

Hearing that it only took such a short time to solidify, the two of them were even more amazed.

Because the solidification time is shortened, it is naturally conducive to shortening the construction period.

Later, when they learned from Zhong Shuyu that the cost of cement was much cheaper than lime mortar mixed with glutinous rice juice, iron sand, and egg white, their hearts were even more agitated.

Because if it is cheap, it means that it can be used on a large scale.

Unlike now, because of the cost of construction, only the city wall, the outer wall of the palace, some wealthy people will mix glutinous rice juice, egg white iron sand to further increase the hardness.

Most of the houses of ordinary people are glued with lime mortar.

But when this cement comes out, it can change all that.

You can imagine how shocking the news was when it spread.

It is not only beneficial to the people, but also to the army.

Because of many military fortresses, the requirements for solidity are very high.

Nowadays, the strength and hardness of this cement can be fully achieved.

It can be said that this is simply a record of the creation and invention that entered the annals of history.

After Shi Lezhang fully understood the purpose of this cement, he did not invite other officials of the Ministry of Works to watch the novelty, but ordered the news not to spread, and he hurriedly went back to write an excerpt.

After Shi Lezhang left, Wang Yuankui looked at this handsome young man with mixed feelings.

When Zhong Shuyu said that he wanted to do this before, he still looked down on it in his heart, thinking that Zhong Shuyu was young and vigorous, but it turned out that Zhong Shuyu really did it in just half a month.

Wang Yuankui had to break his heart.

This is really an unusual teenager.

After that, Wang Yuankui apologized to Zhong Shuyu, saying that he took it for granted.

Although Zhong Shuyu did not hold a grudge against Wang Yuankui's behavior, Wang Yuankui took the initiative to bow his head to apologize, and also pulled her a little favor, so she said a few words to Lord Wang, hoping that he could rectify the invention institute.

Wang Yuankui agreed.

When he came out of this workshop, it was getting late, and Zhong Shuyu went home directly.

That night, because of something in his heart, Zhong Shuyu slept beautifully.

Following.

In the early dynasty, Shi Lezhang presented an excerpt to the emperor and made Zhong Shuyu out of cement and reported it to heaven.

As soon as this matter was said, the ministers of the entire court were shocked.

Is there anything so much better than lime mortar?

Really?

It can't be that Shi Lezhang exaggerates his words for the sake of merit!

The ministers were questioning and inquiring, Emperor Yongsheng read the excerpts, and immediately summoned him, "Chuan Zhong Shuyu entered the palace with cement." ”
