Chu Mansion, study.

After sending Fu Shou back, Chu Feng returned.

At this moment, he made a pot of tea, and took out a drawing in his hand, Chu Feng nodded frequently while tasting tea, with a smile on his face.

cement, and it is a diagram of the production of cement of each mark.

It has to be said that the invention of this thing is definitely one of the greatest inventions in human history, not only because it is extremely stable, but also because the materials used are very common.

lime, clay, gypsum.

Mainly these three things, you can see them everywhere.

The key cement is one of the few water-hard cementitious materials, which means that it can still be used in lakes and is extremely corrosion-resistant.

"Yes, that's good."

Chu Feng nodded with a cup of tea and smiled.

With this thing, sooner or later, it is possible to connect the cities with each other completely, and build bridges in the lakes sooner or later.

When the time comes, every household will be connected to the cement road, how prosperous will this be?

However, at present, it will take decades or even hundreds of years, after all, the current capacity is too low, and if the steam engine can be developed, it may be possible to speed up the progress.

Looking at the drawings, Chu Feng kept smirking.

"Husband, why are you so happy!" Ohashi came over with a bowl of ginger soup, with concern on his stunning cheeks, and stepped forward to put down the ginger soup and asked with a smile.

"Why are you here so late, ma'am?" Chu Feng held the jade hand of the bridge, and his face showed concern, especially the cold palm of the bridge, which made Chu Feng feel distressed.

"It's cold, seeing that you are in the study, I will boil you a bowl of ginger soup, drink it while it's hot, you can drive away the cold." Ohashi rolled his eyes, full of concern.

Chu Feng nodded and took a drink.

Daqiao was wrinkled at this moment, sniffed the air, and immediately said vigilantly: "Husband, why do you have femininity?" You're not going out."

"Huh? Is there one? Chu Feng raised his arm and sniffed it, and then said with some emptiness: "No, it is probably the smell on your body." ”

Ohashi's beautiful eyes narrowed slightly, revealing a somewhat sly expression: "Really?" ”

"Ahem, of course, let's go, I happen to be sleepy too, let's go back to the house and rest!" Chu Feng snorted and immediately proposed to go back to rest.

Daqiao She is also a smart woman, knowing that Chu Feng can't help it even if she messes with flowers and grass outside, not to mention that Chu Feng is so good that some women are too normal,

The mansion is twenty years younger,

It's just that Daqiao is more curious, these sisters in the family are estimated to be the ceiling of appearance, why does Chu Feng still want to eat outside, is it possible that it is more fragrant outside?

"Hmm!" Ohashi nodded.

Immediately out of the study, Chu Feng summoned to the dark, and a black shadow appeared: "Go, pass my order, find gypsum, lime, clay, and stone grinding sieve and put them in the backyard of the Jiangfu, I will have a use tomorrow." ”

"No!" The shadow nodded.

Immediately, with Chu Feng waving his hand, he quietly disappeared again.

Daqiao is no longer surprised by this, at this moment she just wants to go back with Chu Feng hehe, she wants to give Chu Feng another daughter, Dragon and Phoenix Chengxiang.

There was no word all night, and the next morning was unspoken.

Chu Feng only felt tired and sore.

What about his "super" stocks last night, good guy, this stock market is sometimes high and sometimes low, sometimes up and sometimes down, and the people who watch it are shocked, and Chu Feng also pressed hundreds of millions into it.

Chu Feng, as a person who has come over, just wants to give a piece of advice to the young people who want to "exceed" stocks every day, it's not good to invest too deeply, you can't grasp this thing, let the master come!

After a simple wash, all the women have already gotten up.

The breakfast is very simple, dumplings with rice balls, dumplings dipped in a little vinegar with some side dishes, the taste is really good, and the women also fell in love with the dumplings and rice balls that Chu Feng studied.

There's no way, eat more hard cakes or drink porridge in the morning this year, where to fix these fancy intestines.

"Husband, will you go shopping with me today?" Xiaoqiao grabbed Chu Feng's arm with great interest, pouting and coquettishly, wanting Chu Feng to accompany him.

"Husband, play mahjong with us!" Mi Zhen said with a mocking smile, she and Gan Qian were obsessed with this mahjong made by Chu Feng, and the thief was fun.

"Husband, will you accompany me to see my family?"

"Husband, why don't we go."

Ladies and gentlemen, you say a word to me, good guys, this is a competition for favor.

Chu Feng: "??? ”

To be honest, it's not good to buy too many stocks, no, I have the energy to do other things, but he still has urgent things today, and immediately said: "Another day, I still have important things to do today." ”

"Husband, let's just go shopping for a while!" Xiaoqiao's soft and cute pleading,

As the master of the harem, Daqiao immediately said: "Sister, don't be rude, the husband said that there is something important, naturally there is something, and my sister will accompany you to go shopping in a while." ”

Xiaoqiao muttered, "Oh! ”

"Husband, government affairs are important!" Daqiao said with concern, she saw Chu Feng confessing to Huwei yesterday, and she thought that there was indeed something important today.

"Hmm!" Chu Feng nodded and left.

————

After a while, the backyard of the house.

Chu Feng looked at the prepared clay in front of him, Chu Feng stroked his cuffs, eager to try, and immediately said, "Xu Chu, smash these things for me." ”

"Lord, why are we doing some broken stones?" As Xu Chu spoke, he also picked up the hammer and smashed it, just expressing the doubts in his heart.

"Nature is useful, and if this thing is made, it may change people's lives." The corners of Chu Feng's mouth were hooked, and he also began to smash with a hammer.

After a while, a few small piles of material came out.

It's just that at this time, these materials are still very large, and they still need to be rolled with grinding discs or mills until they are rolled into powder, and then they can be mixed to make cement.

Xu Chu was shirtless at the moment, wiping the beads of sweat on his forehead, don't say it, I haven't exercised for a long time, and I sweated after a while.

"It's all going to be powdered!" Chu Feng explained again.

"Lord, if you don't let someone pull two lazy donkeys over, these beasts are just right." Xu Chu asked tentatively.

"Don't rush first, I'm trying to find a way to mass produce it." Chu Feng waved his hand.

Then, the master and servant acted as coolies, or Chu Feng took the initiative to participate in it, and if he wanted to better find the key points of each step, he had to master it thoroughly.

And the news that Chu Feng took Xu Chu to grind in the backyard of Jiangfu early in the morning quickly spread, and for a while, everyone was ashamed, although they didn't know what Chu Feng was doing,

But Chu Feng worked so hard, they had an old face to rest there.

Immediately, they all came.

Lu Su, Jia Xu, Zhang Zhao, Tian Feng, and Fu Zhu are regulars.

But even Zhao Yun, Zhang He, Lu Xun, and Zhuge Liang also came, they all wanted to see what Chu Feng was doing here, after all, grinding early in the morning can't be exercise!

"Lord, what are you?" Zhang Zhao saw that the master and servant were grinding and grinding, and couldn't help asking.

"Why are you here?" Chu Feng was surprised.

"I heard that the lord came to the general's mansion early in the morning to deal with government affairs, how lazy can we be, so I came over to take a look." Lu Su hurriedly explained.

"Oh, that's just right, hurry, come and pull, and there are grinding discs and grinders next to them." Chu Feng pouted, not treating them as outsiders at all.

Zhang He and Zhao Yun are all fine, they are all practitioners, and they immediately stepped forward to grind without saying a word.

As for Zhang Zhaojiaxu, the corners of his mouth twitched, good guys, they suspected that Chu Feng was waiting for them to come over, waiting for them to be a free laborer.

You know, the most tiring things in ancient times,

Take the children to grind tofu with iron, they are similar to grinding tofu.

"Lord, what are you doing grinding these stones and clay?" Lu Su stepped forward and pushed for a while, and asked curiously.

"Make a new material, cement!" Chu Feng was already sitting next to him resting, and at the moment he was sipping a little tea and looking at everyone, he called it appropriate to give them a chance to exercise.

"Cement? What is it? Zhuge Liang's eyes lit up instantly, Chu Feng obviously had something new coming out, and looking at Chu Feng's painstaking appearance, it was definitely not bad.

"A new type of hydraulic cementitious material, corrosion-resistant and high-pressure resistant, durable, with this thing to build roads and bridges, even if it is not repaired for ten or twenty years, it will not be damaged."

Chu Feng took a sip of tea and explained.

With the current world's carriage capacity, even if it is pressed every day, it cannot be destroyed, and it is not like the later generations that will be crushed by dozens or hundreds of tons of muck trucks every day.

"Ten or twenty years without repair, it won't be damaged?"

Everyone was stunned for a moment, and the others may not be clear, but now the rammed earth used to build roads needs maintenance almost every year, let alone ten or twenty years.

If you don't ask all year round, you will inevitably be damaged.

Not to mention worrying about blistering these for a long time.

"Say less!" Chu Feng shrugged.

Then he got up and grabbed the lime powder next to him, felt the thickness, and couldn't help nodding.

"This thing is an epoch-making product, and the city-state built with this thing will be unbreakable, even without fear of flooding and fire." After Chu Feng finished speaking, he immediately came to weigh the stone.

According to the steps in the production method, the response ratio is taken separately, just like building a house in the countryside more than ten years ago, first mixing several things together, and then making a small pit in the middle.

Under the gaze of everyone, Chu Feng began to mix water into it, and then used an iron shovel to stir it there, ensuring that these ingredients could fully absorb water and fuse.

"Lord, can you really do this soft thing?" Tian Feng said bluntly, with a little doubt, after all, he had never seen this thing, and it felt like it was better than rammed earth!

It's a bit like a common man building a house, fishing some mud from the bottom of the river and mixing it with straw poles to build a house.

"Of course." Chu Feng was sure.

Although this is the first time he has made this thing,

But I've never eaten pork and never seen a pig run?

In the past, I often carried ash hoppers for the workers who built houses in my hometown, and to put it bluntly, my right hand was fine, but the work I did was not beautiful.

After a while, the cement was almost overturned.

A small stall was there, Chu Feng immediately found the wooden board mold prepared in advance, then framed a square, and then poured cement into it.

Shovel leveling for an extremely comfortable process.

Chu Feng still remembered that if you want to increase the tension and increase the bearing capacity, you can also weave a steel frame in cement, then mix sand and stones in the cement, and pour it into the steel frame to cool.

It's called a structural column in his opinion.

"It's done, and then it will solidify, so it's extremely strong, and if you want to increase attachment, you can also add sand, brick the façade, and so on."

Chu Feng pinched his chin and said with a sense of accomplishment.

Sure enough, brushing system props is cool, he still has two chances now, a sister of Wu Yi, and a Tang Ji, both of which are famous beauties.

I think I should be able to brush out the task,

I just don't know what to give.

After listening to Chu Feng, everyone waited quietly, if this thing was really as divine as Chu Feng said, wouldn't Chu Feng have made something that could create a precedent?

Thinking of this, everyone looked at Chu Feng from time to time.

This man is really getting stronger and stronger, he really knows everything.

In front of Chu Feng, they were like primitive savages who had not been enlightened.

While everyone was waiting, time passed little by little, from morning to afternoon, the cement was touched, it was still very soft, and everyone's hearts instantly beat drums.

Can this thing really build Chen Bang? Building bridges? Nothing for decades?

"Ahem, it's a cold day, it would be nice if it was summer, but it should be about the same tomorrow." Chu Feng was also wondering, and suddenly remembered this stubble,

"Tomorrow will solidify?" Everyone was stunned.

It's too slow, isn't it?

"Lord, can this thing really build bridges?" Zhuge Liang didn't care when, he was simply curious to ask, because he had learned about the bridge,

At present, the large army crosses the river and the short river by pontoon boats, and the long ones are directly crossed by boats, including the two sides of the river now all rely on ferries, if we can really build bridges, then we can further improve economic development.

Only with very short ditches can people make a simple bridge with stone piers and stone slabs, and a slightly larger one is an arch bridge, but even then it is not very wide.

"Naturally, but the cross-river bridge project is too large, it is estimated that it will be difficult to achieve in a short time, and the collapse of the Huai Bridge has a chance to be realized, and the specific construction situation still needs to be discussed."

Chu Feng nodded immediately, and he didn't dare to guarantee it in his heart.

After all, he didn't build bridges, but he had seen some bridges that used the hull of a ship as a pier, and the inlet was as sharp as a ship to slow down the impact.

It is possible to shorten the distance between each pier, and at most it will cost a few more piers, but these things need to be worked out slowly, after all, the channel needs to be taken into account.

Every step is important, but once realized, it will definitely be a blessing to the people on both sides of the Huai River, and it can further stimulate the economy of the people on both sides of the river!

"Crossing the Huai Bridge?" Zhuge Liang gasped.

Good guys, the Huai River is a relatively wide river except the Yangtze River and the Yellow River, even if it is narrower, there are several miles, not to mention building bridges in such rapids, even if it is very difficult to make a bridge pier.

When everyone heard this, they couldn't believe it.

"Lord, is it really feasible?" Lu Su said excitedly.

"Of course it is possible, this thing can be hardened in water, so it is a hydraulic material, but if you want to build in this kind of river, you need to prepare a lot, after all, building a bridge pier in a river should also need to touch stones."

"That is to say, it is necessary to dig down to the reef first in order to completely stabilize the bridge piers, so as to complete the bridge across the Huai and even the collapse of the river, which is a very large amount of work."

Chu Feng explained very seriously.

The crowd also listened very carefully, after all, these things are usually not heard.

In the end, everyone had to go back and wait for the news, all looking forward to this tomorrow!
