Chapter 478: An Epoch-Making Invention, The Concrete Road Of Dimension Reduction Attack [Please Subs
On the podium, Yan Changqing's eyes glanced at Chu Wang Zhu Zhen and Qi Wang Zhu Su, and he was slightly surprised. He did not expect that the two of them still remembered the matter of cement.
Then Yan Changqing looked at Zhu Yuanzhang, Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di and other princes, and added:
"His Royal Highness the King of Chu and His Highness the King of Qi are generally right. The road that Your Majesty and Your Highnesses take from Yingtian Mansion to [Wanmin Agricultural College] and [Wanmin Medical College] is called the cement road."
“As for the material for pouring cement roads, ‘Kesheng’ named it cement!!!”
“The production of cement can be either simple or complex depending on the raw materials.
"The simplest way is to mix limestone and clay in a ratio of three to one to make cement."
"This method is the simplest and lowest-cost method of making cement."
"If this kind of cement road is poured, then its production cost is probably slightly higher than that of an ordinary dirt road, which is about the cost of building a 150-foot-long dirt road.
A simple cement road of one hundred feet can be built. "
“Another more complex cement production method requires the use of raw materials such as limestone, clay, and gypsum as the main materials, and also adds some mixed materials such as slag, slag, fly ash, copper slag, etc. Auxiliary raw materials.”
“The cement produced through this production method can be further mixed with water, river sand, gravel and other auxiliary materials to make concrete.
"The cost of a cement road poured with this kind of concrete is about twice as high as that of a simple cement road."
"In other words, it means building a 100-foot concrete road, a 200-foot simple cement road, and a 300-foot dirt road."
"Although the cost has increased, its advantages are also obvious"~.
"First, it is easy to plasticize. Concrete cement is like water. What kind of mold it is poured on will determine what shape it will take."
"To use it to build roads, you only need to pour it into the road mold. After it dries, it will become a very smooth and smooth concrete road!!!"
"Second, quick-drying, concrete cement has the ability to set and set very quickly."
"For a concrete cement road, from pouring concrete cement into the road mold to having it solidify on its own, as long as there is no rainy weather, generally speaking, one day is enough for it to solidify on its own."
"Even if the weather is good, half a day or so is almost enough."
“Third, with high strength and stiffness, concrete cement roads have high load-bearing capacity and the ability to spread loads.
"Even if today's horse-drawn carriages are loaded with loads and are driven over and over again on concrete pavement, they will not be cracked!"
"Fourth, it has good stability. The water and thermal stability of concrete cement roads are good, especially its strength will gradually increase with time.
"At the same time, it is less affected by natural factors such as weather conditions. No matter it is strong wind or heavy rain, it will basically not cause damage to the concrete cement road."
"In other words, there won't be any big dust, and it won't look like potholes."
"Fifth, long service life."
"Because concrete cement roads have good durability, strong resistance to wear and corrosion, and strong resistance to erosion, their service life is also relatively long."
"After a concrete road is repaired, it can basically be used for 2,000 to 40 years."
“Sixth, it’s easy to maintain.”
"The so-called ease of maintenance actually means that it requires little maintenance."
"After a concrete road is repaired, as long as it is not violently destroyed by a major natural disaster such as earthquakes, mudslides, or floods that cannot be resisted by humans, then there is basically no need to maintain it on weekdays."
"Seventh, raw materials are easy to find."
"Whether it is making simple cement or making slightly more complicated concrete cement, their main materials and auxiliary materials are not rare and hard-to-find raw materials."
"Among simple cement and concrete cement, the most important and most commonly used raw materials are limestone, clay, gypsum and river sand."
"Such raw materials are available throughout the Ming Dynasty."
"In other words, people all over the Ming Dynasty were able to find these raw materials, then make them into cement, and finally use them to build cement roads.'
Yan Changqing gave a general overview of the raw materials, production methods, related costs, and advantages of cement and concrete.
And just the advantages just mentioned were enough to make Zhu Yuanzhang, as well as the ten princes including Prince Zhu Biao, Zhu Di, Zhu Fan, Zhu Di, etc. moved by it.
After all, the stone road is better than the cement road, but it is not as cheap as the cement road!!!
However, dirt roads and gravel roads, which are cheaper than cement roads, are not as good as cement roads!!!
In addition, cement has the advantages of easy plasticity, quick drying, high strength, high stiffness, long service life, easy maintenance and other advantages.
It can be said that the emergence of cement roads is a dimensionality reduction blow to current dirt roads, gravel roads, and even stone roads!!!
Moreover, the use of cement is not only for building roads, but also for building bridges, building dams, building health, building cities, etc.
It can be said that as long as it is related to construction, it can basically be used.
In a sense, the emergence of cement is an epoch-making great invention for the architectural world and for modern society in later generations!!!
Without the emergence of cement, it would be impossible for modern society to enter the urban era of high-rise buildings!!!
It is not an exaggeration to say that cement is one of the cornerstones of modern society in later generations!!!
Even the reason why Yanhuang was known as the infrastructure madman in later generations was that cement, a convenient and fast building material, also played a very important role!!!
PS1: The serial is hot, and we urgently need all the handsome guys, beauties, and big guys to order and customize! I wish all the big guys who make full orders and customizations to get rich overnight, good health, and all the best.
Good luck! Thank you all! I kneel down to all the bosses!
