Chapter 173 Low-cost and widely used cement

Jian Yunsang followed her gaze and saw... a cement floor.

Sure enough, Chaochao whispered, "The ground is different. Why isn't this tile or wood?"

I've seen cement surfaces every day; roads are basically all made of cement.

But can it be like that inside a house? The places where Chaochao has been living these days have either tiled or wooden floors, and have never had cement floors.

Inside the houses in Shangliu Village, the floors are all muddy, and sometimes when you walk into a house, a cloud of dust flies up.

The people of Daqi under the sky also stared wide-eyed, especially Emperor Jingxuan and his entourage. They were very excited about the smooth road surface when they first saw the carriages driving on it.

The official road in Daqi is in good condition now, but it becomes full of potholes whenever it rains.

Some trucks are loaded with a lot of goods, and the tire tracks left by the wheels are so deep that they are impossible to walk on.

Looking at the road surface in later years, it was fine whether it was raining or sunny. Even heavy vehicles could pass over it without any problems. Moreover, it was straight and stable, which was simply the road of their dreams.

However, the sky curtain never mentioned that they, like Chaochao, had previously thought that such roads could only be used outdoors. But looking at the houses in front of them, the ground was the same.

They looked expectantly at the sky, and thankfully this time they weren't disappointed. Jian Yunsang explained, "This is a cement floor, which is relatively inexpensive. It's much cheaper than ceramic tiles or wood panels, yet easier to clean than mud. If you're not concerned about aesthetics, cleanliness, or ease of maintenance, this kind of floor is quite good."

Chaochao was surprised. So, in their home, as well as in her maternal grandfather's home, hospitals, and hotels, the tiles and wood panels were used for aesthetics and ease of maintenance?

"Low cost?" Chaochao murmured. "No wonder the roads outside are all made of cement. If the cost were high, it would be too expensive."

He Nanzhou walked over and overheard this. He laughed and picked up Chaochao. "Yes, the main raw materials for cement are limestone and clay. Limestone is one of the most common rocks on the earth's surface, so it's easy to obtain. You can make a material by crushing this rock, grinding it into powder, and then calcining and cooling it. Isn't the cost lower than other things? But it has a lot of uses. It can be used to build bridges, roads, and houses, so naturally it's used a lot."

Chaochao opened her mouth, "That's good?"

Jian Yunsang added, "When we walked over just now, we saw them using cement next door. Chaochao, do you want to go take a look?"

Chaochao nodded repeatedly. Su Fangrong, who happened to be bringing over tea, heard this and paused for a moment before saying, "Going next door? It's a bit dusty, wouldn't that be inappropriate?"

"It's okay, we'll stand a little further away, take a quick look and then come back."

Su Fangrong placed the cup on the table and said with a smile, "Okay, then I'll take you there."

She didn't find it strange; as a city kid, she probably had never seen cement being painted.

Su Fangrong was unaware of Chaochao's disappearance, and Jian Yunsang wouldn't discuss such matters with her. She didn't even know that He Nanzhou was the president of the He Group in Jiangcheng; all she knew was that Jian Yunsang was a teacher, a very dedicated and responsible one, whom she respected, and naturally, she also liked Chaochao very much.

The little girl was curious about everything. There were many things in the countryside that she might not have in the city. Many city kids actually preferred the flowers, plants, mountains, and rivers of the village.

After saying goodbye to her grandparents, she led the three of them out of the courtyard.

The neighbor next door was indeed mixing cement. Since it was their own work, it wasn't very noisy, and the cement pile was small. Just as Jian Yunsang and her group arrived, the person turned around.

He recognized Su Fangrong and immediately greeted her, "Fangrong, you're back from your holiday?"

"Yes, I just got back yesterday. What is Uncle Qi doing?"

“We were planning to build a pond outside, but your seventh aunt insisted on growing some ornamental hydroponic plants, like pothos or something. I told her it wasn’t practical, but she wouldn’t listen. So, I just got her a water tank and let her do what she wants. It’s not much trouble anyway.”

As he spoke, Uncle Qi squatted down and vigorously stirred the cement and water a few times. Then he slapped a lump onto the bricks that had been laid and carefully smoothed it out with a scraper.

Chaochao stared wide-eyed, just watching.

So this is what cement looks like when it's freshly applied? The road surface is so hard and smooth, but before it was finished, it was as soft and fluffy as mud and sand.

She asked He Nanzhou in a low voice, "Dad, after this is painted on, can it still hold water?"

"Of course, cement has good sealing properties and can be used to make water storage equipment. Therefore, cement is also used in many large-scale water conservancy projects."

Emperor Jingxuan, under the canopy of the sky, could no longer restrain himself and suddenly stood up, shouting, "Yu Kangsheng, Yu Kangsheng!"

This time, Yu Kang Sheng didn't back down. He was equally excited and his face was flushed as he said, "Your Majesty, I have remembered it. I will go and experiment with it later."

The other ministers' eyes also lit up. Although He Nanzhou did not explain in detail how to do it, he had given the general process and ingredients.

They're not stupid. After all this, with everyone contributing their ideas, surely they can make this cement?

This cement is so useful and has such a low cost, it should be widely promoted.

Yu Kang Sheng is now quite impatient. Everything else that is still unclear and has no progress can be put aside. The cement needs to be produced first. He believes that soon, Daqi will also be able to use such a good thing.

Emperor Jingxuan was in a great mood and couldn't help but move closer. His seventh uncle had already skillfully finished brushing a piece of bread.

He nodded as he looked, "Hmm, so that's how the walls are painted, and that's what the cement looks like after it's done."

He found Jian Yunsang and He Nanzhou rather endearing today, as they explained the convenience of cement so clearly.

Uncle Qi scrolled through the screen for a while, then noticed that Su Fangrong was still watching with her guests. He was taken aback and asked, "Fangrong, is something wrong?"

"No, it's nothing." Su Fangrong couldn't help but look at Chaochao.

The latter hesitated for a moment, then gripped Jian Yunsang's hand tightly, slowly mustering his courage before finally asking, "Uncle, how does this cement harden?"

Uncle Qi was taken aback. He looked at the little girl and saw her shrink back in fear. He quickly smiled and said, "This, after you've finished brushing it, put it here and let it dry in the sun. It will harden in a day or two."

He couldn't help but wonder to himself, "Where did this little kid come from? Even painting cement looks so good on her."
Uncle Qi scratched his head, and seeing that Chaochao was still watching, he subconsciously asked, "Do you want to try it?"
