Zhao Hao didn't know that his old enemy came to Suzhou from Songjiang in order to deal with him.

He was pulling Jiang Xueying and Hua Bozhen, and rushed to test the effect of building the wall the day before yesterday.

I saw that the walls had been completely glued together, and the gray gaps between the bricks looked uneven and intermittently covered with hoarfrost.

Zhao Hao took the dagger handed by Gao Wu and slashed towards the brick crack. The harsh sound of metal grinding left only a shallow scratch on the top.

Then he walked over to the wall that had been cemented with three-fold clay, and slashed at the brick joints as well. With a snort, the dagger stabbed two fingers into it, and brought down a large piece of solidified three-fold soil.

Hua Bozhen couldn't help but widen her eyes, these are completely two concepts.

He hurriedly stepped forward and pressed the new mortar solidified in the crack of the wall with his fingers, and it was as solid as a stone, no wonder the sharp dagger could not help it.

Hua Bozhen pushed the wall harder, but did not move.

Then he kicked with his foot and pushed hard with his shoulder, but the wall remained still.

Zhao Hao hurriedly grabbed the more energetic Brother Hua, who is in his forties, why don't he know how to cherish himself?

In order to satisfy Hua Bozhen's obsession, Zhao Hao asked Gao Wu to find a hammer and slammed it a few times before smashing a big hole in the solid brick wall.

And the wall cemented with triple clay, Gao Wu achieved the same effect with just one hammer...... That's why the walls have to be thick enough.

"The intensity needs to be improved." In this way, Zhao Hao was still a little dissatisfied.

"Time is still short." Yu Ben said softly: "Childe, Jiangnan is too trendy, I'm afraid I have to wait for three days to achieve the same effect in Beijing." ”

When Hua Bozhen heard this, she said in her heart that people had been studying this thing for a long time.

"It's not just a matter of time." Zhao Hao frowned and said, "I have to adjust the formula again, next time you try to add some iron powder." ”

"Yes, Childe." Yu Ben hurriedly responded in a deep voice.

"The glutinous rice mortar is nothing more than that, you still don't think it's strong enough?" After Yu Ben retreated, Hua Bozhen couldn't help but say loudly: "This is to be stronger again, and then don't think about demolishing the built house in the future." ”

"Hahaha, that's right." Zhao Hao laughed when he heard this: "For building a house, this kind of cement is indeed enough." But what I'm going to use to build the levee needs to be strengthened a little more. ”

"It's called cement?" Hua Bozhen's eyes lit up and said: "'The smoke opens and the green fan is clear and the wind is dawning, and the cement is red and white and dewy'." What an elegant name. ”

Zhao Hao heard that this sweat, sure enough, it was still his meow's literati who would arrange it, and it was the first time he had heard that the name of cement was elegant.

"Brother, can cement really replace glutinous rice mortar?" Jiang Xueying, who had always been quiet, asked softly.

She knows that there are currently two types of mortar used to bond masonry, the commonly used triad mortar, and the glutinous rice mortar with excellent performance.

But the former has limited strength, and the latter is too expensive......

A new section of the city wall was built in Suzhou the year before last, which was originally built with glutinous rice mortar. But after only two miles, a full 100,000 catties of glutinous rice were consumed.

Even the wealthy Suzhou Mansion couldn't afford it, so it had to obediently change back to the mortar of Sanhetu.

So if you want to use glutinous rice mortar to repair the embankment, even the wealthy Zhao Gongzi can't afford it.

What's more, there isn't that much glutinous rice available.

"It's a complete substitute for glutinous rice mortar, and as the recipe improves, the performance will surpass it." Zhao Hao said confidently: "And it can be hardened in water, which is incomparable to glutinous rice mortar." ”

"Wouldn't that be as long a levee as you want?" Jiang Xueying's beautiful eyes also radiated excitement.

"Of course." Zhao Hao nodded proudly: "With this thing, I can build a levee for the entire Kunshan!" ”

~~

Zhao Hao's confidence comes from this Xishan Island.

This magical island is rich in high-purity limestone for cement, and there is also a considerable amount of gypsum - these two which, together with clay, are the three main ingredients for firing cement.

But Zhao Hao did not use clay, but used the kaolin, which is abundant on the island - because calcined clay, the purpose is to obtain kaolin. Therefore, this step is directly omitted, which can greatly save time.

There are also enough open-pit coal mines on the island – replacing wood with coal as the main fuel for calcining cement that could reduce the calcination time from seven days to two days.

There is no shortage of iron powder or iron slag, another important ingredient for cement. However, Zhao Gongzi has not yet found the location of pyrite......

You don't have to go out of the island to produce less high-quality cement, magical!

Zhao Gongzi wanted to change the name of Xishan Island to 'Cement Island', but fortunately, he was also a literati, and after all, he couldn't help but burn the piano and cook the crane.

He lowered his voice and said to the two: "Now the two of you know, our Jiangnan company, what should we do next, right?" ”

"Repair the embankment! Repair the embankment! Repair the embankment! Hua Bozhen was excited and said important things three times.

Jiang Xueying couldn't help but be excited: "If we can easily build an indestructible embankment, the entire pattern of Jiangnan will be changed!" ”

"Not bad." Zhao Hao nodded with a smile and said, "This inconspicuous cement was born to change the shape of the world!" ”

"Good brother, you must leave this job to me!" Hua Bozhen grabbed Zhao Hao's arm tightly, almost begging.

"As long as the eldest brother can walk away, of course the company can't ask for it." Zhao Hao smiled and nodded.

"No problem, I'll arrange it." With Zhao Hao's approval, Hua Bozhen was overjoyed. He approached the brick wall with a big hole, and while stroking the rough cement in the brick joints, he said with joy: "Brother, I will be famous in history, and I rely on this cement!" ”

Zhao Hao couldn't help but look at him with admiration, but he didn't expect that the eldest brother of the Hua family was really sharp-eyed, and he could actually foresee the greatness of this invention at once.

"It's too far to leave a name in history, let's make a little money now." Zhao Hao smiled and said to Jiang Xueying: "My sister must have thought of what to do." ”

"There is cement invented by my brother, and my little sister suddenly thought of more than a dozen ways to make money." Jiang Xueying smiled and said, "But don't worry about anything else." However, I think we should start buying some of the land that is about to be completely changed by the concrete embankment in advance. ”

Saying that, she whispered: "This is based on my brother's practice in Xishan Company. ”

"Hahaha, that's what I thought too." Zhao Hao nodded with a smile, and then said with a smile: "But there is one thing that please forgive me, Jiangnan Company only rents and does not buy land in Kunshan." ”

"This is a matter of course, Ling Zun is in charge of Kunshan, and it is really not good to buy land to our company." Hua Bozhen smiled understandingly.

"Of course, it's all up to my brother." Jiang Xueying is naturally even more so. "And what about the other counties?"

"There are no limits." Zhao Hao smiled and said: "I see that there is a large tidal flat east of the Huangpu River, we might as well concentrate on eating that section first and then talk about other places." ”

"Okay, if my brother doesn't dislike it, I'll leave this matter to my little sister." Jiang Xueying took the initiative to ask Ying.

"That's a good feeling!" Zhao Hao was overjoyed. "This unfamiliar person is worried about who will take care of this."

"We will not fail in our mission." Jiang Xue welcomed the elegant Ying Ying Yifu.
