Hand rubbing nuclear fusion live in the wilderness

Chapter 74 Limestone - fired to make cement

With a bamboo basket and an iron ax on his back, Han Yuan plunged into the jungle.

Generally speaking, to survive in the wilderness, if you want to explore a strange place, it is best to arrange a whole day or two or three days.

Because you can't go too far in the morning, you will return soon, and the area to explore is also very small.

Unless you're lucky, the odds of finding something good are much smaller.

But this morning he just went to the other side of the river to see, and then walked along the river to see if there were any resources on the other side.

It doesn't necessarily have to be something useful to explore, and checking out dangers is also one of his goals.

After all, this is where he will live in the shelter for the next ten days, and it is also one of the necessary tasks to ensure that there is no danger nearby.

When he came to the river, Han Yuan found a wooden stick as a walking stick.

Last night, there was a torrential rain for an unknown period of time. The small river, which used to have a small flow, is now much wider and the water flow is a little more turbulent.

So he prepared to cross the river with a wooden stick as a cane to prevent himself from falling into the river.

Across the river, this is his second time across the river.

The first time I wanted to follow the traces of bison to find salt, and finally found a salt mine as I wished.

I don't know if I can find anything good this time.

The trees on both sides of the river are not very different, they are all those tree species. Han Yuan left the river, entered the depths of the jungle, and then carved marks all the way to explore the depths of the forest.

On the other side of the river was the same mountain peak, first flat, then gentle and then steep. After exploring the terrain, he didn't go any further.

Instead, explore along the direction of the lower reaches of the river.

In the far downstream, along the river, there is a salt mine that was explored last time about two hours away.

And the scope of his exploration this time is to walk from here to the salt mine, and then come back along the river.

But walking in the forest is much slower than walking on the river bank.

It takes at least four or five hours to explore from the forest to the salt mine, plus two hours for returning, the morning time is just right.

Entering the forest, before going far, Han Yuan made his first discovery.

A person hugs a thick avocado tree.

If you look closely, you can see a lot of avocados on the branches.

If you search the ground, you can also find some black unrotted cores.

The fruit known as 'avocado' has high nutritional value and in addition to being eaten raw, it can also be used in cooking and canning products.

The only problem is that the avocado tree is quite tall, and how to go up to pick the fruit is a problem.

But I'll figure it out later.

Now he collects the fruit stones scattered on the ground first, and after searching the ground, he finds some fruit stones and puts them all into bamboo baskets.

Avocado kernels contain a lot of fatty oil, which can be eaten, but forget about the ones on the ground, God knows if the inside is bad or not.

His purpose of collecting these fruit stones is not to eat them, but to use them for lighting at night.

An avocado pit can burn for 15 minutes after being lit, which is an excellent natural candle.

When burning, it will not drip grease and flame, and it will emit a light fragrance.

Good luck finding an avocado tree and harvesting these pits.

In addition to these fruit stones, there are many avocado saplings around. If you have time, you can transplant them to the wooden house.

After collecting the fruit cores, he carried the bamboo basket on his back and continued on his way.

It seemed that he had used up his luck when he found an avocado tree. After walking for more than an hour, he didn't find anything useful.

Won has no choice but to move on.

Exploring unknown areas is like this. Sometimes if you are lucky, you will encounter many things one after another. Sometimes if you are unlucky, you will not gain anything after running all day.

Go straight ahead, the trees in front of you start to become scarce,
After walking for a while, a bunch of messy stones were piled up in the forest, some big and some small.

Judging from the accumulation traces of the stones, it should be that after the stones on the mountain have been subjected to wind and rain for many years, mudslides have occurred, and these stones have also been brought down.

Han Yuan didn't care either, this kind of thing is normal on the mountain, until he accidentally hit a huge rock with an iron ax when he passed by it.

Then, with a light knock on this huge rock, a small piece of it collapsed directly.

This immediately caught his attention, he stopped, and turned his head to look back curiously.

Don't look at no gains, look at the gap, and immediately feel happy.

This pile of scattered stones turned out to be limestone.

He picked up a small piece of limestone that had just been knocked off, handed it to the camera, and said with a smile: "After walking for so long, I finally made some new discoveries. Does anyone know what I'm holding in my hand?"

【Stone? 】

[Isn't it just a broken stone?Could it be some kind of baby? 】

【I am a good kid!Never lie, I said: I don't know. 】

[What the hell?What's the use of being ugly?anchor. 】

[Where is the big student who recognized the iron ore and taught the anchor where to find the flint?Are you still here? 】

[Don’t look for him anymore, I can tell you that this is limestone, the main component is calcium carbonate CaCO3, which can be used to burn quicklime. 】

Seeing that someone has already answered his question in the barrage, Han Yuan shook the limestone in his hand and said with a smile:
"That's right, the stone in my hand is limestone, except that it can be used to make quicklime and slaked lime."

"It's also one of the main raw materials for making cement!"

The audience in the studio was shocked immediately.

【cement! ! ? ? 】

【Fuck? 】

[The anchor is going to step directly into the era of big industry? 】

[Scary, cement production is about to start, is the next step going to be building high-rise buildings? 】

【Concrete can do everything, this anchor can do anything!】

[Let me just ask, when will a lithography machine be built! 】

[Is there a class representative?What about the chemical formula of limestone fired cement? 】

Looking at the bullet screen, Han Won said, "There are four main raw materials for firing cement."

"Limestone, sandstone, and iron ore powder, these three are the basic raw materials."

"These three raw materials are ground and mixed according to a certain ratio and then calcined to obtain cement clinker."

"The clinker is then mixed with the final raw material 'gypsum' and ground into a powder to obtain cement."

"Although I haven't found gypsum yet, I can make simple cement powder first. Although the effect is not as good as ordinary cement, it is still very good."

"I'll write down this place first. After two days, I'll make up some 'Luo Dou', and then I'll move some limestone back."

"At that time, I can use cement to reinforce the outer wall of my wooden house. The rainproof effect is better than that of the earth wall, and it saves labor."

　Take a leave in the afternoon and go back to my hometown to get the vaccine (the second shot)
　　I wanted to take a taxi in Changsha, but I still didn't make an appointment, so I just went back and forgot.

　　Missing chapters will be added later.

　　Ask for a monthly ticket, ask for a recommendation.
