Chapter 13 How is cement made?

After buying some medicinal materials and tea leaves and taking them back to the house, Fang Jun saw that nothing happened, so he rushed to the new house and planned to gather people to start building the new house.

Originally, he wanted to build it with wood, but after thinking about it, Fang Jun gave up the idea.

Since it needs to be clean and tidy, why should we use a wooden house? It is better to build a stone house directly. This will also be of great benefit to asthma patients. To treat asthma, it must be in a very clean environment without dust!

However, it was not easy to build a stone house in the Tang Dynasty.

Nowadays, most people live in wooden houses. The use of stone is not only bulky, but also very expensive. In ancient times, few people could afford it.

And there were no bricks, clay or cement in ancient times.

Fang Jun thought for a while, and found that clay is relatively easy to find. It only takes a while to find it. As long as the clay is found, you can build a stove and bake bricks directly.

As for cement…

This thing is quite difficult to handle.

How is cement made?

It seems to be made by mixing lime and clay.

Fang Jun thought about it seriously, and it seemed that cement was not a rare thing.

After all, a long time ago, when Qin Shihuang was building the Great Wall, he used a kind of lime mortar. By adding yellow clay to the lime mortar, a very strong cement could be obtained.

Then it is recorded in "Tiangong Kaiwu" that in the Southern and Northern Dynasties, some people added glutinous rice soup to lime mortar.

In this way, a super strong adhesive can be obtained, which is no less strong than today's concrete.

Most of the city walls in ancient times, including part of the Great Wall, were made of these things. Otherwise, they would not have survived for thousands of years.

After thinking about it, Fang Jun felt that it was feasible. Since he was not very short of money now, he might as well just use the silver to build a brick kiln nearby to collect clay and bake bricks.

I just don’t know if there is any clay nearby? I need to find someone to ask.

With this in mind, Fang Jun called Tianfu over and asked: "It's similar to Guanyin soil or eel mud, but it's yellow and has a certain stickiness. It's called yellow clay. Tianfu, go out and ask someone in the nearby mountains or

It doesn’t exist in farmland. It usually appears in farmland! If there is, please report it to me quickly!”

Tianfu looked surprised and asked in confusion: "Second Young Master, this Guanyin Tu is valuable. What do you want Second Young Master to use it for?"

Fang Jun immediately shook his head and said: "It's not ordinary Guanyin soil, it's just like Guanyin soil, but yellow clay. I remember that there is this kind of thing in swamps with water, or in farmland! Ordinary people are very fond of it.

Use less of this.!”

Tianfu was stunned for a moment, thought for a while and said: "Second Young Master, Tianfu knows about this thing. Someone dug it up before and took it back and burned some ceramics. However, it is not very useful. The burned ceramics will crack quickly, so many people

No need."

Fang Jun was overjoyed: "Is there one nearby?"

"There seems to be some outside Chang'an City! If the second young master wants it, Tianfu can find someone to find some! But this thing is too dirty. I wonder what the second young master will use it for?" Tianfu asked.

"There is one outside Chang'an City? Then take me there and have a look!" Fang Jun was overjoyed. There is such a thing nearby, so why bother?

Just ask Tianfu to find someone.

As a servant of Fangfu, Tianfu naturally had some connections. He quickly found a few people and led Fang Jun towards the outside of the city.

It is said that people have dug a lot in the farmland outside Chang'an City in the past, but the pottery produced was not very effective, so some people stopped using it.

Fang Jun was very interested and followed them to see if they could find clay. That would be the best, as it would save him a lot of effort.

When the time comes to build a brick kiln directly outside the city specifically for burning bricks, I wonder if Li Shimin and the Fang government have any objections?

They were not afraid of their opinions. Baking bricks was not a big deal. Qin Shihuang had done it before. How many furnaces did Fang Jun burn?

It just might make people look down upon it.

Fang Jun was too lazy to care about this, and walked out happily. On the way, Tianfu looked at him, as if he had something to say, but he hesitated, but he held back.

Everyone in the Fang family is a little strange now.

Many people said that since the second young master of the Fang family got married, he seemed to have changed into a different person. He was no longer as arrogant or domineering as before. Instead, he always did some weird things.

s things.

First, I went to Guizhou to find some magic fruit, which shocked many people in Chang'an and made people laugh. Now I'm looking for ceramic clay, which worries Tianfu to a certain extent.

However, Tianfu did not dare to interfere in his master's affairs, so he could only go with him.

A few people were about to walk out of the city. At this time, they suddenly saw a large group of scholars coming out of the city.

This group of scholars seemed to have just gone out to play, reciting poems, or going on an outing to enjoy the scenery.

Since the imperial examination in Chang'an will be held in one month, the city of Chang'an is now filled with scholars from all over the world.

It is said that many of them were talented and well-spoken, and recited many poems and quatrains, which were talked about by many scholars in Chang'an and became very popular. Even Fang Yizhi, the eldest young master of Fang Mansion, would occasionally participate.

Fang Jun was originally a martial artist with no ideas. He had always been disliked by these people, so he also looked down upon these scholars.

But at this time, a gorgeous Luan chariot appeared in front of this group of scholars.

There was a beautiful curtain covering the Luan Car, so that the people inside could not be seen. There were two elegant palace maids sitting in front of the car. It seemed that it was the car of Princess Gaoyang.

Fang Jun knew that the Princess of Gaoyang had always liked dancing, writing, poetry, calligraphy and painting. She often gathered with some scholars to recite poems, write poems, and go on outings to learn about folklore. Otherwise, she would not have looked down on the illiterate Fang Yiai, a warrior.

The last time I saw her was in Fang Mansion. She was as proud as a peacock and didn't even look at Fang Jun. It was quite interesting to meet her now.

Fang Jun and his party walked over, and Princess Gaoyang and her party came out and bumped into each other.

There seemed to be many people in the group of scholars who knew Fang Jun, and there was a lot of discussion. They discussed a few words in low voices, with expressions of ridicule and narrow-mindedness.

It seems that the second young master Fang has done a lot of stupid things recently.

Princess Gaoyang has a lot of fans, most of them are children of the gentry. Princess Gaoyang has a good reputation. She is not only beautiful, but also well-educated. Some time ago, it was said that Princess Gaoyang was going to marry the second son of the Fang family, which made many people sad.

, heartbroken.

Then news came that the Second Young Master Fang was said to have married Princess Jinyang, the sick young lady of the royal family. Everyone was overjoyed. Princess Gaoyang was not married yet, so when they met at this time, they naturally had a few words of teasing.

Whether you are jealous or trying to get away with someone, how can you have so much good looks when you meet your love rival?
