Chapter 123 Perfect Soil
The strength of rammed earth is inversely proportional to its water content.
In other words, the higher the water content in the soil, the less flat and firm it will be. You must try your best to control the water content.
Although it will look very flat and smooth when water is added, as time goes by, the surface water evaporates and the soil layer becomes empty.
At present, we are just leveling the land, so there is no need to pay too much attention to it. However, if we are building a vertical earth wall, we need to be careful, otherwise there is a risk of collapse at any time.
Xia Tian believed that Si Ye could solve the rammed earth problem, so while he was out looking for materials, she looked for soil on the nearby mountain wall that could be used to build the stove.
The cave they live in now is backed by a small hill. The vegetation around it is very lush, and the soil condition should be pretty good. It is not difficult to find some suitable soil.
Xia Tian went out to patrol the mountains carrying a backpack and a stone axe.
A girl, holding an axe, walked around the hill with a serious expression, observing the situation intently. The scene was quite...
[Hahaha, the anchor is holding an axe, with a serious face as if he is seeking revenge]
What the hell is this magical picture?
[I don’t know why, even though this girl is so cool, I find it hilarious.]
【Shan: Don’t come over here!!!】
Xia Tian was observing the soil layer at this time. The soil should be fine enough and as free of sand and gravel as possible, so it is necessary to find a place with many plants, so that the humus is thick and the soil underneath will be better used when dug out.
She took the axe not to seek revenge or for self-defense, but to make it easier to clear vegetation and dig the soil underneath.
After walking around for several times, she finally found a place that she was satisfied with.
Xia Tian swung the stone axe and began to clear the vegetation. After finishing, she turned to use the axe to continue clearing the exposed mountain wall.
There was no way. She didn't have any tools like a hoe at the moment. The surface soil was basically humus and was completely unusable. To dig out useful soil, she had to dig half a meter to one meter deep.
Anyway, it's not a delicate handicraft, just shoveling the soil, it's the same with an axe.
Once the dark brown layer of soil on the surface was cleared, the grayish yellow layer of soil inside was revealed - this was the raw material she was looking for.
Xia Tian placed the stone axe head facing down against the wall at her feet. She first picked up a little with her fingers and tested its fineness on her hand. It didn't feel rough at all and had little sand.
Then he grabbed a ball of loess and held it in his palm. He squeezed it hard and opened his hand. A basically formed lump of soil appeared in his hand.
Then she turned her palm over, and the soil in her hand fell to the ground, hitting the leaves with a small sound, and then turned into debris.
Perfect soil.
Xia Tian thought so in her heart.
"It can be squeezed into a ball by hand and breaks into pieces when dropped to the ground" is the gold standard for judging the plasticity of soil in practice.
It is no exaggeration to say that such soil can be used directly to make pottery, and it would be a waste of material to build a stove.
She decided to use this and picked up the axe again to "chop the mountain" and collect soil, but the audience in the live broadcast room was still confused.
[Although, I thought my sister was going to chop wood, but why is she chopping dirt? ]
[I see she's still collecting them. What's she going to use them for?]
[I don’t know, the host didn’t even explain it, it’s so confusing???]
[But I'm so envious, there's still soil in this place hahaha]
[I understand you, I have never seen the real thing since I was born]
