Like Li Dongyang, Zhou Jing and Zhang Mao were also the same. They looked at the narrow official road behind them and the spacious cement road under their feet. They couldn't believe what they were seeing.
"Is this still a road?"
Zhang Mao sighed like this. Looking at the clean and tidy cement road, he even felt that he did not dare to step on it for fear of dirtying the road.
"Haha, of course this is the way."
Dong Xiaoshan looked at the three people and smiled. He had seen such expressions more than once. Almost every new person who comes to Tianjin will be deeply shocked by this spacious and flat cement road. Some victims were even too scared to walk on it because the concrete road looked cleaner than their homes.
"All this is thanks to Mr. Liu, who invented cement. This cement and sand and gravel are mixed according to a certain proportion, and mixed with water. It can not only be used to build bridges and pave roads, but also to Build houses, fortify cities, etc.¡±
"It is very simple, convenient and fast to build. The key is that the road is not afraid of water erosion. As long as it dries out, no matter how heavy the rain falls, it will not have the slightest impact."
Dong Xiaoshan is a very qualified commentator, and he explained the advantages of cement one by one.
In the past, he didn¡¯t believe that there could be such magical things in the world. Building houses, building roads, etc. have always been big projects, and they are definitely not easy tasks.
But with this cement, everything has become much simpler. The key is that the houses, roads, etc. built are very strong, not afraid of water intrusion or fire, and the speed is very fast, saving time, effort and money.
"Three adults, please come and take a look."
After looking at the expressions of the three people, Dong Xiaoshan continued to lead the three people to the place where the cement slurry was mixed.
It is also very busy here. There are carriages transporting cement from the Tianjin Cement Factory. There are also long lines of victims carrying sand and gravel from the Haihe River in the distance. There are also people carrying this sand and gravel. People who mix cement and cement together, pour water on them, and keep stirring.
"This is cement. Cement and sand can be mixed according to a certain proportion to form cement slurry. If it is used to build houses and be used as an adhesive, the sand must be fine sand. If it is used to build roads, use Ordinary sand and gravel are enough, there are no big requirements.¡±
Dong Xiaoshan pointed to the cement and then to the cement slurry that had been mixed. Here, the victims were picking up load after load and carrying them to the front to build roads.
Li Dongyang, Zhou Jing, and Zhang Mao didn't care whether it was dirty or dusty. They went straight to the cement storage area, reached out and grabbed a handful of cement from the barrel, and looked at it carefully.
The cement was gray and felt like fine flour. There was nothing too special about it. But if they hadn't witnessed what they saw with their own eyes, they wouldn't have believed that this thing could be used to build bridges. Pave the road and build such a spacious road.
"This is a divine weapon! With this thing, my Ming Dynasty will no longer have to worry about building city walls."
Zhou Jing couldn¡¯t help but screamed.
He is the Minister of the Ministry of Household Affairs, so he naturally knows all the expenditures of the imperial court. The Ming Dynasty's annual expenditure on building city walls is a huge expenditure.
When the Ming Dynasty was founded, because of its strong military power and the ability to rely on powerful force to deal with the nomadic peoples in the north, the reliance on building city walls was not serious. However, starting from the founding emperor Zhu Yuanzhang, the Ming Dynasty has been building the original walls of the Great Wall. The Great Wall was basically built to defend against the attacks of northern nomads.
After the Tumubao Incident, the Ming Dynasty no longer had the ability to conduct large-scale expeditions against the Mongolian tribes. Therefore, it became more urgent and important to strengthen northern defense and build the Great Wall defense system.
Starting from the orthodox emperor Zhu Qizhen, the Ming Dynasty carried out large-scale construction of the Great Wall. This process lasted until the end of Jiajing, and the whole process lasted 130 years.
It starts from Hushan in Liaoning on the Yalu River in the east, to Juyongguan and the eastern foot of Qilian Mountain in the west to Jiayuguan in Gansu, connecting the Great Wall of Qin and winding for more than 6,000 kilometers. It is extremely majestic. The Great Wall seen by later generations is actually the Great Wall built in the Ming Dynasty.
The construction of this Great Wall is extremely unsuitable. The eastern section of the Great Wall is mainly made of green bricks and strips of stone. It is very strong and the cost is naturally high.
As for the western section and most of the other Great Walls, they are actually built with earth. The rammed earth wall is made of wooden boards, filled with clay or limestone, and built layer by layer with a pestle.One meter costs about one tael of silver.
From this, we can know how much manpower and material resources were spent on building the Great Wall. Starting from Zhu Yuanzhang and ending with Emperor Jiajing, it almost ran through the entire Ming Dynasty. With the efforts of successive emperors, It took 200 years to build the Great Wall.
¡°It is almost impossible to calculate how much money, manpower, inability, etc. have been spent.
In addition to building the Great Wall, the towns in the capital and border areas also need to be built, which is also a huge expense.
Zhou Jing, the Minister of Household Affairs, is very aware of this. The Ming Dynasty was already poor and too poor to open the pot, but it still had to spend a lot of material and financial resources on building city walls every year.
Now that he saw this cement and the spacious road that was built very quickly and simply, he couldn't help but sigh like this.
With this cement, building the Great Wall or the city wall will become very simple. It is just some sand and gravel, plus some water. Simply mix and stir, and the built road will be as hard as Stones are not afraid of wind and rain, nor are they afraid of being burned by water or fire.
"It is indeed an artifact!"
Li Dongyang, like Zhou Jing, also held a handful of cement in his hand. He looked at the cement slurry being mixed around him, then at the spacious cement road next to him, and then looked back at the road being built rapidly and forward. He also felt the same emotion. An inner sigh.
"With this artifact, my Ming Dynasty will no longer have any worries."
Zhang Mao also nodded and said: "As long as we build a city wall with cement in the border town area, the Mongols will not even think about entering half a step into our Central Plains land."
"Not just building city walls, if our Ming Dynasty uses this kind of cement to build such spacious official roads all over the country, then our Ming Dynasty will be extremely convenient whether it is dispatching troops and punishing generals, or transporting grain from the south to the north."
Li Dongyang finally had a smile on his face. When he came to Tianjin once, he seemed to have seen a brand new Ming Dynasty, a powerful Ming Dynasty. The cement in his hand was no longer cement, but an artifact, an artifact of the Ming Dynasty's strength. (Remember the website address: www.hlnovel.com
