"Oh, Uncle Liu, you can't do this, it's not strong. "www.biquge.info Liu Qingxi waved his hand, this is not right.

"What? We've been doing this for generations, and no one is saying it's wrong?"

Even if this group of people just now believed in her as gods, compared to their ancestors, Liu Qingxi still had to lean back.

"Uncle Liu, what I said is true, didn't you find that when I was repairing the house, I made everyone mix the mud with crushed grass? ”

"Also, the soil we dug out can't be used directly, we must first go through a sieve to sift out the small pebbles inside, otherwise it is not good to leave them inside. ”

Speaking of which, Liu Qingxi also thought of a way, if the excavated clay soil is added with an appropriate amount of coarse sand as the skeleton part of these blocks, it can reduce the dry shrinkage deformation and improve the strength of the block.

It's just that this sand, if the particle size is small, it can't be used as a skeleton, not to mention the bearing force, but also reduce the viscosity, and if it is large, it can't be effectively bonded with the soil, and it will reduce its integrity.

It's a pity, it's a pity, there doesn't seem to be suitable sand here, it's all big rocks.

There are no advanced tools here, which can directly crush large stones, and Li Jing can do whatever he wants, so this improvement method can only be abandoned, and it is obviously not suitable for the current environment.

It is still necessary to choose materials that can be taken locally, simple and convenient, and easy to transport, so adding the admixture of crushed grass is the most realistic way.

"Didn't you see that the house reinforced by my method is stronger than ordinary, which is the reason why these things are added. ”

Of course, Liu Qingxi did not explain to everyone the addition of broken grass, which is actually equivalent to the role of tie bars in the concrete structure, and people will not understand the explanation.

Only when the most intuitive and credible facts are in front of them can they recognize and accept them.

"You think, if we add broken grass, when it is about to crack, the grass tendons inside will not be broken, won't it not break?"

Liu Qingxi's easy-to-understand explanation still makes people seem to understand.

Forget it, anyway, I can't explain it clearly, and I can only prove it with facts.

Liu Qingxi didn't expect that one day, in this strange era, he would use the method of comparison to do experiments.

"Okay, okay, I know you don't believe what I said, so let's not add grass tendons to hit a few adobes, add grass tendons to hit a few more, let's go back and find some heavy objects to press, see who breaks first, you will know which one is good, okay?"

Village Chief Liu has more experience than young people, and thought about it: "Cheng, that's it, let's try it!"

Anyway, they have nothing to lose, and they just need to use whichever method is better.

"Okay, in this way, we must make the adobe of the same size, if it was originally such a big adobe, we would definitely not be able to crush it. ”

Although soil is a raw material, the strength of these adobe blocks themselves is not high, but in this era of lack of experimental instruments and control equipment, it is difficult to accurately obtain its mechanical property parameters.

Even if you want to crush it, you can only use the method of pressurizing heavy objects, think about it, the compression resistance of dozens of KN, but not a little bit of heavy objects, it is impossible to achieve.

So there is only one way, to change the size of the adobe and reduce the compressive performance of the block, so how to do it?

The easiest and most effective way is to increase the length and reduce the thickness, so that the compressive performance will be greatly reduced.

Although it is not an adobe prototype and does not use a scale-down model, it cannot quantitatively reflect the mechanical properties of the soil, but according to this comparative test, the influence of the admixture on the mechanical properties of the bulk can be qualitatively judged.

Finally, in order to load the weight, the length of the original billet was doubled and the thickness was reduced by half.

"Uncle Liu, I'm afraid I'm going to trouble you to prepare this mold!"

"No problem, there is a carpenter in our village, and it will be done in a while, so why don't you do it over to us?" After finishing speaking, he reflected, as if it was so troublesome to Liu Qingxi: "Let's go back and let's come!"

So this experiment was tentatively scheduled, and in order to start construction as soon as possible, the people of Sanhe Village prepared in Kashgar as soon as they arrived home.

In the afternoon of the same day, the village chief Liu was the leader, and the shrimp soldiers and crabs came with them.

At this time, there were rumors about this experiment all over Shilipu, and even more directly mythical about Liu Qingxi.

"You don't know, this girl Qingxi has thought of a good way again, and the house is stronger. ”

"It's so powerful, haven't you heard of it, and you've started working as soon as it's warm?"

"That's not it, the village chief of Sanhe Village did it himself, who made them not believe it, how do you think I know? ”

"Oh, what's this method, what's the comparison? No, I'll have to take a look. The curious woman patted her ass and got up and walked west.

What a gimmick?

After a while, the women gathered around each other dispersed, but they had the same destination, Liu Qingxi's house.

"Wait a minute, I'll go find the soil I want, and you can make a few pieces of the soil you dig up casually. After saying that, Liu Qingxi walked to the foot of the mountain, and she remembered that there was a piece of land over there that was yellow, which should be clay.

As for the soil under your feet, although it is a little sticky, it is still not enough in comparison.

How could there be so few onlookers in such a lively matter? When Liu Qingxi went out, he was even followed by a long line of people.

"Qingxi, where are you going? ”。

What help, Liu Qingxi sneered, it's true that he wants to join in the fun!

There was a rough place in her heart, Liu Qingxi found it at the foot of the mountain, and when she squatted down to prepare to dig, the curious teenagers squatted down to help, and dug enough weight in three or two minutes.

"Qingxi, is it really okay?" Song was one of the onlookers, how did he feel a little unreliable?

Although she knew that Liu Qingxi did have some ability, if the method she came up with failed, what could she do?

It's easy to get a reputation that will be ruined: "If it's not for my aunt to say you, you shouldn't take this poison, in case you lose......"

She didn't say the next words, I believe Liu Qingxi can understand.

A soothing smile: "Auntie, don't worry, there will be no problem!"

In modern times, so many people, with countless experiments to verify the results, how can there be wrong, adding broken grass, wheat straw these measures, has been compiled into the standard, and its content also has certain requirements.

She didn't doubt the possibility of winning at all, winning was a must, otherwise she would hang a lasagna and hang it back, maybe she could roll her eyes and go back to modern times.

"You ......" Song wanted to ask her where she got her confidence.
