Others are fleeing famine, but I am a salted fish

Then, pour the mixed material into the prepared mold and compact it to form the shape of chalk. After placing it on the blackboard to dry naturally, you will get white and hard chalk.

While waiting for the blackboard and chalk to dry, Lin Xiaoyue did not delay and went back to tinkering with the cement formula.

Before she started to make them, she carefully reviewed the building materials she had seen here, and they were indeed mainly wood and stone. Occasionally, there were wealthy families who had too much money to spend, and in order to make them stronger and store grain, they would compress the grain into thick and dense glutinous rice bricks, and then use them to build houses.

Of course, she had only heard of this and had not seen it with her own eyes.

After all, if there really were wealthy people building their houses with glutinous rice bricks, she couldn't just go up there and lie on top of their wall and dig at them with her fingers.

If he were discovered, he would be arrested and beaten to death as a psychopath.

After thinking about it carefully, she realized that this dynasty probably lacked durable concrete building materials like modern ones. So she didn't hesitate and started to prepare.

The basic components of cement are limestone, clay and minerals. The limestone here is of high quality and the clay is abundant, providing a good raw material basis for making cement.

While collecting raw materials, Lin Xiaoyue was also working on making the tools needed to make cement.

Since there are no ready-made machines, she can only rely on manual production, commonly known as manual crushing.

Fortunately, her biggest advantage was her strength variation. She could crush, mix, and grind into fine powder on the stone mill with great vigor by herself, and she didn't feel tired at all.

Then mix lime and water in a ratio of three to one. This was clearly marked in the book, so she didn't have to bother trying it out step by step.

After the three materials are mixed evenly to form cement slurry, it is finally fed into the mud kiln and continuously stirred and calcined into mature material. Before the moisture dries up and solidifies, she uses a modified simple wheelbarrow to pour the fluid cement slurry on a seldom-used corner, and then smoothes it with a wooden board.

After a period of time, the water in the fluid is gradually evaporated. In modern times, polyacrylamide is added to produce chemical reactions, improve the working performance of cement slurry, reduce the water-cement ratio, and accelerate the hydration and hardening process of cement.

Although the book gave clear proportions and there was no need for repeated experiments, due to the lack of modern tools, Lin Xiaoyue spent a lot of effort to perfect the production process and find the best production plan.

At the same time, Lin Xiaoyue was pushing a simple wheelbarrow and running around, making quite a noise, and it was hard not to attract attention.

After a few times, when the floor was being paved, Grandpa Lin and other people who had free time came over to watch. Some of them were so curious that after watching Lin Xiaoyue paving the floor several times, they reached out to help.

After everyone watched and did it a few times, they seemed to understand something, but Lin Xiaoyue didn't say anything, and they didn't rush to ask, because she would tell everyone in the end anyway.

-----------------

It took about ten days. One day, after dinner, Lin Xiaoyue and several sisters carried two large blackboards to the front hall and showed the dried blackboards and chalk products to everyone.

Everyone looked at her writing and drawing on two large, shiny black boards, 3 meters long and 1.8 meters wide, with expressions of amazement.

In line with Lin Xiaoyue's explanation, the two blackboards can be placed specifically in the two areas for distilling liquor and making instant noodles, and everyone's monthly production progress can be announced on them at any time.

This way, grandpa can save time and effort in counting, and everyone can see each person's production progress and quantity more intuitively.

Grandpa Lin stroked his chin, listened to Lin Xiaoyue's explanation, and couldn't help clapping and shouting, this is convenient and practical, it saves him from the women and children who always surround him and nag him every now and then, asking him how much he has made, which annoys him a lot.

Women and children always like to ask grandpa how much they have done and how much someone else has done. It’s not that they are worried about grandpa’s accounting, but that the desire to compare is at work.

What they compete with each other for is not who has more wealth as shown by the wealthy families in the city, but who is more capable, more agile, and has done more.

I have to say that these people are really simple. They work hard every day, fearing that they will fall behind and be teased as lazy women.

If this happened in modern times, it would be a complete king of rolls, and it would be scary.

As for the problem of illiteracy, Lin Xiaoyue also made some good suggestions.

On each board, list the names of the producers of the corresponding project in a vertical column. If you look at their names every day, no matter how stupid you are, after ten days or half a month, you will be able to recognize your own name and the name of your most important "competitor".

The horizontal columns use the character "正" to represent the quantity produced. One stroke represents a successfully distilled jar of wine or a pound of instant noodles. A full character represents five jars or five pounds, and so on.

From the beginning of the month to the end of the month, whoever has more positive characters is the most diligent, and the corresponding marketing results of the month's sales will be divided according to the corresponding quantity.

In this way, it is convenient and easy to count, and it allows everyone to achieve the goal of learning to read and write imperceptibly. Isn't it a great thing that kills two birds with one stone?

Naturally, the launch of the blackboard and chalk received unanimous recognition and praise from everyone. Everyone, including Grandpa, was deeply attracted to the new writing tools made by Lin Xiaoyue. They touched and admired them, and everyone couldn't put them down.

Blackboard and chalk: ...That's enough, stop touching me, or I'll sue you for indecent assault...

Then, Grandpa thought that the blackboard and chalk could be used on a larger scale in the farm, so he asked Lin Xiaoyue about the production process and materials of these two things. If it was not difficult, he wanted her to make a few more.

If the finished product is as large as the one currently on display, you can make another one and nail it on the wall in the hall, and write down the orders and things to do every day or over a period of time on the board one by one.

First, it is not easy to forget and serves as a constant reminder;

Secondly, by reading and writing more, everyone can recognize more words. Now that they are not in the countryside, they can do business by knowing more words and understanding more principles, and they will not be easily deceived.

Compared with expensive paper, pens, blackboards and chalks, Sanma is cheap and can be reused.

In addition, you can also make some smaller and thinner ones that can be carried on the back of each person or are easy to carry.

In this way, everyone can write down any unfamiliar words at any time and come back to ask each other.

Speaking of the writing system of this dynasty, it is very peculiar, and resembles traditional Chinese characters. Lin Xiaoyue was a cultured person who grew up under the red flag in modern times, but when she came here, she found that the writing system was different from that of modern times, so she could only learn it from the beginning, word by word, from the beginning.
