Travel through the Three Kingdoms

Chapter 183 Ironmaking and Cement ([-])
"My lord, what are you?"

Everyone was puzzled, why did Yang Yu bring them to such a rugged mountain road?
"Hey, the mountain road. I remember that there was no road here. Why is there a road now? However, how do people walk on such a mountain road? Look at the stone, which is still sharp. If you step on it, even if you don't If your feet are penetrated, you will also sprain your feet, right?"

"Hehe, you don't know about this mountain road, but some time ago, did you hear that this place was rumbling all day long? Yes, it was at that time that gunpowder was used to open mountains and build roads. However, next , it's time to witness a miracle!"

Yang Yu said mysteriously.

It turned out that in order to prevent the so-called dust pollution, Yang Yu built the cement plant in the deep mountains, and there happened to be no shortage of limestone in the deep mountains, and there were a small amount of clay piles, but the clay was really not enough, so , Yang Yu came up with this idea. Originally, the road was also going to be built. So, it is better to build this road first, and even build a railway at the same time.

The railway is not in a hurry, Yang Yu just asked to repair the roadbed, that is, lay a thick layer of stones under the road first, and these stones are the stones blown out by driving this road, even if it is If there is something missing, it can be shipped from other places, but now, the road is paved first.

Yang Yu estimated the reserves of clay in the mountains. Generally speaking, after the road has been repaired, there is still some leftovers.

"This is, how about spreading this wet soil on the road so that it won't flow away? Even if it doesn't flow away now, won't it still be washed away after it rains?"

When everyone was researching where this miracle was, they found that there were many wheelbarrows pushing some wet gray soil, and there were some stones in the soil. What is this for?

That is to say, this is the amount of the first kiln, and Yang Yu used it for experiments. However, Yang Yu believes that even if the quality is slightly worse, it is completely enough for road construction, especially for this Still a hard road.

Because this is the first experiment, whether it is stones, cement, or sand, they are all strictly weighed according to the proportion, so there is a saying that they are pushed by a wheelbarrow.

This time, a lot of people were mobilized. It can be said that the workers of the entire cement factory were mobilized. Soon, a long section of the road was covered with mixed concrete.

Then, someone leveled the spread concrete, and even supported the corners with wooden boards. When the concrete hardened, the shape of the roadside would be better.

After that, some people dragged some stone rollers and rolled on it to compact the road surface, and some people were repairing some obviously defective places.

This old way of paving the road is inconvenient. There is no electric vibration pump, so this method can only be used for compaction.

"Everyone, this is a new building material that I have produced during this period of time. The name is cement. If this experiment is successful, it will be quite convenient for us to repair the city walls and even build houses in the future. As for whether it’s practical or not, we’ll have to wait a few days to see.”

"My lord, it's true. Just this gray mud can be used to repair the city wall. Is it better than yellow mud, or is it better than glutinous rice soup and mud?"

"Well, I can't say for now, but if the experiment is successful, it will definitely save money and food compared to glutinous rice soup and mud. Alright, let's go back. We'll come back to watch after three days."

Yang Yu's words were a little secretive. This time, he wanted to let people know what this thing looked like at the beginning. After three days, they will be shocked!

…………

"Hehe, I don't know what's going on with that road?" "What else can I do? Is it possible to walk in now? I guess, if people go up now, they will fall in."

"Skipping, it's unlikely. At that time, when the gray mud was just being paved, there were some slips, but later, after compaction, it just fell apart..."

All the people came to the road construction site with a lot of discussion.

"This, this, this is?" When they arrived, they found that many people were carrying water and splashing it on it. At this time, it was no longer the rough surface when they walked last time. Rather, a fairly flat surface.

After everyone left, another layer of concrete mixed with cement and sand was put on it, which can be regarded as a fine layer.

"Hey, I didn't expect it to be so strong, but what does watering mean? Well, you can even make a scratch with your fingernail." Some people were anxious.

I ran up to the top, jumping and jumping, but Yang Yu didn't dare to let them use any tools to smash it. After all, this is still a stage of visit. Now, the concrete road is still being hardened , That is to say, it’s okay to go up with a light load. If it’s a heavy load, such as a horse running at high speed, maybe, the horseshoe will step on some small pits on the road surface, not stepping down, but vibrating.

"How about it, everyone, how do you feel now? This is the effect. A section of the city wall that is not high can be built within three days. You can even build it up without waiting for the adhesive to dry completely. Even, if it took ten days to build a house before, with this cement, the frame can be built in one day, and then the beams can be installed on the third day."

As an old-fashioned masonry structure house, if clay is used as the adhesive, it usually takes five to ten days to build the walls. It is not because the speed is slow, but the clay adhesive needs a certain amount of drying. Time, if the time is short and the construction is fast, the wall will easily collapse. However, the cement is used as an adhesive. As a three-meter-high wall, it can basically be built within a day. However, There is also a difference in the thickness of the wall. If the wall is too thin, the clay adhesive will not be able to build it. If cement is used as the adhesive, then it needs to be built in sections, and it will take a hard time. , but, again, not more than three days.

"My lord, what's the matter with the sprinkling?" "Cement needs water. In the early stage, it needs to be kept moist at all times. In this way, this section of the road will become stronger. Naturally, this sprinkling can't be too much water." It's too early, it's too early, before it's hardened, it will wash away the mortar. Well, everyone has a new insight. After five days, we will come to check and accept it. At that time, this The road surface is completely formed, you can use weapons to smash it to see how the road is getting acquainted."

Yang Yu said confidently, but what he really thought in his heart was, "Fortunately, it's a success. This time, the phone didn't miss me."
