"How do you know? Did you eavesdrop?" Yan Laoer asked nervously.
Yan Yu was speechless. Is she that kind of person with no taste?
Can there be more basic trust between father and daughter?
She pointed to her little head.
"They are all here. I just saw Uncle Hu helping to mix a white powder, and I immediately remembered it."
The formula of soil cement with only a few raw materials is really easy to remember.
Of course, remembering the raw materials is not enough, the most important thing is the proportion.
Yan Yu didn't know how good Master Lu's recipe was, but what she knew was that it was the result of countless people's improvements and summaries.
It is also the common choice of many online authors.
"Master Lu should use clay, quicklime and gypsum."
She secretly motioned to her father to look.
Yan Laoer pretended to glance over casually.
There should be no doubt that the clay was pulled back with the help of the boys in their village.
Lime can also be seen, but only gypsum, which he cannot distinguish.
"How do you know it's plaster?" Yan Laoer asked curiously.
Yan Yu smiled like a little fox, "I don't know him, but Mr. Cui does. Gypsum is also a medicinal material. I went over to rub some of it and asked him to help me identify it."
Yan Laoer was convinced.
"Is it that simple? Then why is Master Lu covering it up so tightly? Wouldn't anyone who cares know better if he pays more attention?"
Yan Yudao: "My dad, of course it's not that simple. The proportion is very important. Also, I doubt that Master Lu will add anything else."
"What to add?"
Yan Yu thought for a while and said: "I have seen people say that the cement strength of this kind of soil is still very sufficient, but the frost resistance is poor and the solidification is slow. If you want to solidify quickly, just add some Glauber's salt. If it has frost resistance,
Adding some more adhesive should improve things a lot."
An idea flashed in her mind and she said: "Dad, this is Guanzhou, a border city, and the mortar recipe for building the city wall is the best. I remember that in ancient times, glutinous rice was boiled into slurry and mixed with sand. It was very strong. Wait, let me
Think about it, brown sugar, elm bark, camphor tree sap, hahaha, yes, that’s it!”
Yan Yu was extremely proud of herself. Looking at my memory, she asked who else was there!
If it weren't for the wrong occasion, Yan Laoer would have wanted to lift his daughter up.
So cool!
Even better than Sambo!
He thought of the geothermal project that failed miserably.
Asked his daughter: "Dabao, tell me, is our geothermal heating good?"
Yan Yu looked at her father speechless.
"Dad! Let's be realistic. Geothermal heat should not appear in the homes of ordinary people like us. If you ask me, the prince of Guanzhou and the British royal family may not be able to enjoy this blessing."
She wrinkled her little face and said earnestly: "How can we be so virtuous, dad!"
Yan Laoer:
"The fire wall is very good, and even the fire bed is delicious." Yan Yu thought that she was about to roll on the fire bed, frying both sides and was not looking forward to it.
"Is your recipe better or Master Lu's?" Yan Laoer asked.
"Of course it's me." Yan Yu replied.
"Then what should we do and replace his plaster?" If there is a good one, of course I want to use it on my own house.
Yan Yu gave up Yan Laoer's idea with just one sentence.
"Boiled glutinous rice, brown sugar daddy, that's not a binder, that's all money!"
Yan Laoer was convinced, and the father and daughter happily decided to remain the same.
"But if we get rid of these two, we can try the other ones." Yan Yu was gearing up for a big fight.
"Soil and cement are so versatile. If they can be restored, no, it will be enough for us. After the house is built, we still have a courtyard wall and a stone floor in the house. The yard can be leveled with cement.
By the way, there is also a toilet! Dad, let’s not worry about the heating, the toilet is the key point!”
They realized the importance of squatting as soon as they came through.
When mentioning the toilet, Yan Yu said again: "Let's use our own fertilizer to build a cement pond for them. Dad, the pit you dug is too shallow. Let's learn from experience and dig it deeper next time."
Yan Laoer:
He also said that he was obsessed with things. At least the things he was obsessed with didn't smell bad, but his daughter actually thought about these smelly things.
Yan Yu knocked on his head in frustration.
It's a pity that my brain is not fully functional, and I can't remember a lot of things.
Just like glass and wine making, these are magical skills that make you rich in time travel!
Yan Laoer didn't have time to talk to his daughter anymore, so he went to the fields by the river as if in a hurry.
When we reached the end of the field, we couldn’t help but sigh: Aunt Rong is really the best!
The weeds are piled up so neatly.
All he has to do is light a fire.
Burning grass must be treated with caution, especially in areas with lush vegetation. If it is not done correctly, it will cause serious problems.
Yan Laoer called several uncles from the Song family nearby for help.
The old Song family is also prosperous, but unlike Village Chief Luo's family, they are prosperous with their daughters.
Old Man Song and Old Lady Song are capable, and the girl is good-looking and capable. They are unique in finding a son-in-law. We are not talking about getting married, but after the young couple gets married, they will live in our old Song family. If they agree, they will not need any betrothal gifts.
Just the fact that there is no need for betrothal gifts makes people from ten miles and eight villages flock to her.
There are too many people who are willing to not marry into the family, not change their surname, and still eat rice and grain from the old Song family.
No, three daughters can earn three uncles.
The fourth son of the Song family was originally a single Miaomiao with a somewhat weak body. Since the three brothers-in-law were welcomed in, not only his body and bones have become stronger, but also a young boy has been brought to the Song family.
The fifth son of the Song family is one year younger than his daughter.
What is this called? It’s called wisdom!
What's the difference between recruiting three uncles and picking three sons for nothing!
Yan Laoer felt that he had to learn from others.
Enrich your own experience.
First light a small fire, then rake up the grass one by one. Don't be impatient.
The fire started quickly and the flames spread very high.
There is no wind today, which is really a good weather for burning grass.
The four people always controlled the fire to prevent it from burning out.
The grass hasn't dried yet, and the smoke is billowing.
Yan Laoer ran away for a while to catch his breath, then quickly ran back.
Mask mask!
God, he misses the mask so much right now!
He didn't know how to cherish it when he wore it every day, and only regretted it when he no longer had to wear it.
Whoever chokes knows the pain of being choked.
If you give him another chance to burn grass again.
He will definitely make a mask first!
The three aunts of the Song family went home for lunch after being burnt to ashes.
Yan Laoer thanked him.
The third uncle of the Song family is quite happy.
"Brother Yan, please burn some more grass to greet me."
Yan Laoer:
It’s also a lot of fun.
Back at his homestead, Master Lu was leading people to sift clay.
The soil that has been sifted several times is finely ground into a dough, and mixed evenly with quicklime and gypsum in a certain proportion.
Pour water and mud.
Then
Master Lu did as his daughter said and poured two bamboo tubes of water into it.
Yan Laoer came closer curiously and moved his nose.
Sweet taste.
It's brown sugar.
At this moment, Yan Laoer felt relieved.
Master Lu’s craftsmanship and his construction team have blessed the cost of brown sugar.
It actually felt like great value for money.
