The Great Wall of China has been standing for more than 2,000 years. The Great Wall was originally built in the Qin Dynasty, which was a very distant era. At that time, people built houses with concrete and reinforced concrete that were not used by modern people. The modern buildings are basically made of reinforced concrete, so that the built houses can be stronger and the years of use can be longer.

So what materials did Qin Shihuang add to the Great Wall so that the Great Wall could stand for more than 2,000 years?

King Qin's Military Defense Project

Qin Shi Huang was the first emperor worthy of the name in Chinese history. He single-handedly established China's first centralized feudal dynasty and left a deep impression on Chinese history. During Qin Shi Huang's reign, although his rule was relatively brutal, he was also a man of political vision and military ambition. For example, in terms of military defense, he built the Great Wall of 10,000 miles. At that time, the Qin Dynasty had just been unified, and the internal affairs had not been completely stabilized. At such a moment, the nomadic peoples of northern China began to harass the borders of the Qin Dynasty.

For example, the Huns. The Huns fought with the Qin army for many times . Although there were wins and losses, the Qin Dynasty did not fundamentally defend against the invasion of the Huns . Later Qin Shihuang came up with a strategy, that is, to build the Great Wall that stretches for thousands of miles to defend the northern frontier of China, and to assign Qin soldiers to guard each beacon tower.

It is precisely because of the protective effect of the Great Wall that for a long time, the northern nomads did not interfere with China's frontier areas , so that the people of the Qin Dynasty could live peacefully and happily without being harassed by foreign nations. The manpower and material resources required by Qin Shihuang to build the Great Wall were enormous. Many people worked hard every day to build this Great Wall all their lives.

According to historical records, it took Qin Shi Huang a total of 9 years to build the Great Wall . In modern society, the Great Wall has also become one of the symbols of China and a symbol of Chinese civilization. The Great Wall was built in the Qin Dynasty, and now it has been baptized for more than 2,000 years . During these 2,000 years, the history has undergone earth-shattering changes. Stand firm.

Glutinous rice juice as building material

What are the building materials used in the Great Wall?

This is permeated with the profound wisdom and strategy of Qin Shihuang. According to relevant literature records, the material used in the construction of the Great Wall by Qin Shi Huang was glutinous rice juice. Of course, glutinous rice juice does not refer to a drink made purely from glutinous rice. Its essence is to boil glutinous rice into a sauce, and then mix it with cement. The mixing ratio is also very particular.

After the two are integrated, the resulting building material has very good adhesion . The sturdiness of its material can be compared with modern reinforced concrete. In contemporary life, many families use glutinous rice to stick couplets or couplets during the Spring Festival. How much glutinous rice is needed for the glutinous rice juice to build the Great Wall? At that time, the overall productivity of the Qin Dynasty was relatively low, and the world had just been unified, and people's food and clothing problems had not been fundamentally solved. In such a situation, will a large amount of glutinous rice be used to build the Great Wall, will it be criticized by the people?

Even in contemporary China, where productivity is more developed, the use of glutinous rice juice to build materials will incur huge costs , and the price is astronomical. I believe that no one wants to use glutinous rice juice to build houses. However, in the Qin Dynasty, the building material used in the construction of the Great Wall was indeed glutinous rice juice, which required a lot of glutinous rice raw materials. Qin Shihuang still insisted on using a lot of glutinous rice materials to build the Great Wall, which caused a great burden to the people, but Qin Shihuang still insisted on his own proposition.

According to the records of relevant historical documents, Qin Shihuang asked people all over the country to plant a large amount of glutinous rice and use a large amount of glutinous rice to build the Great Wall against foreign enemies. Although the construction of the Great Wall has caused a lot of mental pain and a lot of energy to the people, we now have the opportunity to see the great Great Wall . He spared no expense to build a unique Great Wall. In the process of building the Great Wall in the Qin Dynasty, another ingenious method was to use local materials.

Using local materials and using chemistry to build a city

The construction of the Great Wall requires a lot of manpower and material resources, and various accidents may occur during the transportation of related materials to the construction site. Therefore, the builders at that time tried their best to select local materials and make full use of the existing materials. for the construction of the Great Wall. For example, people often mix sand and reeds to build the Great Wall.

There is a lot of salt in the reed, and a lot of alkali in the sand. When salts and bases mix with each other, a chemical reaction occurs, and new chemicals are created that have strong adhesive properties. This is a proper practical example of ancient chemical theory! Therefore, the new building materials combined with reeds and gravel can make the building stronger. Now people have to admire their intelligence and ingenuity when they mention that the working people of the Qin Dynasty used this method to build the Great Wall.

In the field of military protection for later generations of the Qin Dynasty, the Great Wall played a unique role. The Great Wall's terrain is very high, and there are many opportunities to monitor the enemy's every move . Even if the enemy suddenly attacks, there is enough time to defend, and the beacon tower above the Great Wall is even more impressive and has a very practical military function. In addition, the Great Wall also plays an important role in hoarding weapons and food. It can cope with long-term military battles, and it can also provide soldiers with sufficient food and grass to cope with arduous battles.

The Great Wall built by Qin Shi Huang is a great symbol of Chinese civilization. As far as modern society is concerned, Qin Shihuang has become an important symbol of Chinese civilization, which has increased patriotic enthusiasm and self-confidence among children of all ethnic groups in China. The Great Wall of China is unique in the world . When people see this magnificent and magnificent Great Wall, they think of the diligence and wisdom of the ancient Chinese people. The Great Wall has now become a symbol of China, a great symbol, it embodies the wisdom and bravery of the Chinese people, and embodies the great spirit of the Chinese people!
