Ancient natural disasters: The whole family traveled through time and was almost wiped out

Chapter 77

In modern times, reinforced cement is used to build houses. In ancient times, the main bonding materials between bricks and stones were generally lime mortar and glutinous rice mortar.

Glutinous rice mortar is a building material certified by scientists as being able to keep the Great Wall standing for a thousand years. Its strength is in no way inferior to modern concrete, but it requires cooked glutinous rice, which is too expensive for most people to afford.

In comparison, lime mortar is low-cost and very strong. Although it is not as strong and is afraid of humid environments, it is still widely used in the construction of houses for ordinary people.

But the bad thing is, it's raining heavily now.

If it collapses before the rainy season is over, when winter comes...

Dehumidification is imperative.

Calcium chloride is hard to find, but calcium oxide is everywhere on the mountain.

Hunter Jiang's family and tailor Jiang's family were preparing to build a new house next year. They had prepared the materials early and transported large chunks of limestone back home from the mountains, but they had not yet had time to dig a pool to soak in.

Heavy rain was coming, so the house could not be built, but it was still a big effort to get it down the mountain, so they found a house to put it in.

Tailor Jiang's house is right in the middle of the village, so the neighbors can just move a few pieces back home. But Hunter Jiang's house is on the mountain behind his house, so the patrol team has to go up and move the pieces down.

After learning that she didn't need to buy limestone in the mall, Jiang Xiaomi wanted to leave. But now that she was out and wearing a raincoat and a hat, she decided to go "enjoy the rain."

After staying at home for so many days, she may not feel moldy physically, but her heart is about to get moldy.

"Other people appreciate the rain hitting the banana leaves, but you appreciate the sound of the rain crackling. You are the one who enjoys the leisurely and carefree life, right?" Jiang Xiubai almost laughed, but he also wanted to follow them: "While we can still go out now, we might as well walk more. In a few days, we won't be able to go out even if we want to!"

"If you want to go, hurry up. If you're slow, I won't wait for you!"

"Let me put on my raincoat first!" Jiang Xiubai said.

"Come back!" Jiang Yipei shouted, "Have the custom-made raincoats for the patrol team arrived today?"

"Let me see, yeah, here we are!"

"Go to the canteen and get it first, we'll need it later!"

Jiang Xiubai and Jiang Xiaomi had no choice but to go back to the store wearing raincoats and take out the customized raincoats.

At this time, people from patrol team one and team two arrived. Jiang Yipei asked them to go directly to the canteen. There were about a hundred people, and the canteen was packed.

Jiang Yipei distributed the customized raincoats to them: "Line up, one set per person, come and get them."

The temporarily formed team already had a sense of discipline. When they got the "raincoats" and "rainboots" in their hands, many people didn't know why each person was given a set of clothes and a pair of shoes.

These shoes are quite strange, they are high-top and have two rows of large iron nails on the soles.

Tailor Jiang was stunned and exclaimed: "These are oil-coated jackets and oil-coated boots! And they are made of tung oil!"

As a senior expert who has worked in the textile industry for half his life, he knows the value of these two things very well.

"Ah?" I haven't heard this for a few days.

But those who had heard it all held their oiled clothes and shoes carefully, and looked at Jiang Yipei with shock in their eyes.

There were also "raincoats" in ancient times. They were similar to ordinary clothes, but they were coated with tung oil, so they were also called "oil clothes."

Ancient rain boots were waterproof long boots coated with tung oil, so they were also called oil boots, which are similar to modern rubber boots.

"Oil-coated clothes! Only the masters, ladies and young ladies of the rich and powerful families can afford them!" exclaimed many people who knew the value of the goods.

Oil-coated clothes and oil-coated shoes both use the water-repellent properties of tung oil to achieve the purpose of waterproofing. In ancient times, the production of tung oil was low and the price was expensive, so the cost of oil-coated clothes and oil-coated boots was extremely high.
