Chapter 17 Indigenous cement
Chapter 17 Homemade Cement
After living a gentle life in his house for a few days, Zheng Kezang began to worry again.
The vacation for the young men at the youth camp is coming to an end soon, and Zheng Kezang wants to recruit another group of students.
But this faced a real problem: the Dongning Military Academy dormitory was not enough, and the civilian laborers at the monument could not be easily used, and he was embarrassed to ask Chen Yonghua to recruit civilian laborers for him.
Recently, when he went to court to discuss matters, the group of old men from Zheng Jing's small court put a lot of pressure on him. The work officer Xie Xian often cried and complained that too many craftsmen were assigned to the monument, and the work of the Ministry of Works could no longer continue.
He had no choice but to try his best to comfort these little old men. Fortunately, his father-in-law Chen Yonghua helped him withstand most of the pressure.
Since ancient times, ministers have opposed the emperor's large-scale construction projects because glutinous rice is used. In ancient times, there was no cement. Glutinous rice juice is a good building adhesive. The material is easy to obtain, but it is a waste of food. In ancient times, food was life.
As long as there is food, there will be a steady supply of reserve troops.
Wait, cement! Zheng Kezang has forgotten to invent cement while he is busy training. This thing has no technical content. Zheng Kezang, a top student in civil engineering, knows how to make cement.
You know, Zheng Kezang’s former project manager taught him this: On the construction site, if you pick up steel bars, you will be a steel bar worker, and if you pick up a hammer, you will be a carpenter. You can do everything, and you will not be eliminated wherever you go.
At that time, Zheng Kezang wanted to reply: Pick up the teacup, I am the project manager.
Zheng Kezang thought carefully about whether traveling here was a different kind of running away with a bucket.
As a result, the Sui Dynasty established very accurate census data and thus established a strict household registration management system. Each state and county cleared household registrations once a year. This household registration management system allowed the imperial court to control every corner of the private sector, and almost no one could
Evade taxes and corvees.
The household registration system established in ancient times was originally to establish a stable tax source for the finance. However, in order not to over-squeeze the people, this household registration system must maintain a certain degree of flexibility, or ambiguity, so that the people can avoid some exorbitant taxes and miscellaneous taxes.
This is human nature. If you suddenly get a large amount of money, you will also have this desire.
Cement is known as one of mankind's greatest inventions. With it, both military and civilian construction will undergo earth-shaking changes. It is a key product that must be produced by all kinds of time travelers if they have the ability.
As soon as he finished speaking, Zheng Kezang said without any doubt: "Old Li, you don't have to worry about this. The supervisory country will naturally have a way. You can just follow the regulations with peace of mind. As for how to make cement, I will go there in person when the time comes.
Teach workers.”
As for land statistics, the Sui Dynasty was greatly exaggerated. According to statistics in the ninth year of Emperor Kaihuang's reign, there were 1.94 billion acres of cultivated land in the country, which converted into modern acres was 2.13 billion acres, which was more than the current cultivated land.
It was large, but the territory of the Sui Dynasty was not as large as it is now. During the Han and Tang Dynasties, China's cultivated land had been around 500 million modern acres, which shows how exaggerated the land statistics of the Sui Dynasty were.
But from the court's point of view, as long as the people are not forced to live in rebellion, it will be fine. During the Three Kingdoms period, some counties in the Shu Kingdom surrendered to the Wei Kingdom. Cao Pi found that the household registration in these places was incomplete and confusing, and the population and land statistics were highly inaccurate, so he wanted to make strict statistics.
Because of the top-down ruling order of the ancient dynasties, there was basically no big risk in the oppression of subordinates by superiors. The exploitation of officials by the people could be said to come randomly. There was basically no restriction on lower-level officials adding additional taxes and fees to the people.
After watching for a long time, his face lost its composure, and he said with a bitter look: "These civilians, no, they are workers. Each worker needs 500 cash per month, and they also include food and accommodation. Your Highness, even if you kill me, you can't be so wasteful."
ah."
After Emperor Wen of the Sui Dynasty unified the country, he conducted a strict census in the area east of Mount Laoshan. Everyone had to register with the government. If someone was found to have concealed something, not only would he face severe punishment, but he would also be issued a ration.
Zheng Kezang was in a good mood, but Eunuch Li was heartbroken after listening to it. He couldn't understand the first sentence, but after hearing the second sentence, he started to build a lot of things. His legs suddenly went weak and he almost stopped standing.
Emperor Yang of the Sui Dynasty carried out large-scale construction projects, dug connecting canals, built palaces, and launched wars to conquer Goguryeo and Tuguhun. At this time, the people were already very poor.
The disaster this kind of statistics has caused to the people is self-evident. The imperial court levied excessive taxes based on this land statistics. The actual land output is not that much. Can the people not be poor?
Because the court's tax collection machine was too efficient, wealth quickly accumulated in the hands of the court, while the people continued to slide into poverty. This laid the seeds for the government to force the people to rebel during the Sui Yang Emperor's period.
The method is simple. Next, it’s time to recruit workers and open a cement factory. With cement, the quality of the monument’s project will be greatly improved.
Emperor Wen of the Sui Dynasty strictly carried out land and population statistics, and thus established an extremely efficient tax collection system. The wealth of the people was quickly depleted, and the emperor had abundant finances. The desire to spend money arose, and the urge to concentrate on doing big things was like
Teenagers in adolescence have an unstoppable desire for the opposite sex.
Eunuch Li could barely accept this treatment, but he looked puzzled: "Your Highness Jian Guo, what do you mean by making money every day? What on earth is cement?"
Then take 20-25% of the quicklime, and add plaster of paris if possible. Grind the gypsum ore or waste gypsum model into fine pieces, heat it in an iron pot to 130-180 degrees and stir-fry it until it turns yellow-gray to adjust the cement solidification speed.
It is useful, but it can be omitted.
It was impossible for Zheng Kezang to listen to Lao Li's advice, because his system of wonders would inevitably require large-scale construction in the future, and he believed that the fundamental reason for the rapid demise of the Sui Dynasty was not the large-scale construction, but tracing the root cause to Emperor Wen of the Sui Dynasty.
Lao Li took the paper from His Highness Jianguo's hand and looked through it carefully. He saw a few big words on it: Articles of Association for the Establishment of a Cement Factory.
Opening a factory is a big event. Zheng Kezang called Old Eunuch Li, picked up a stack of paper on the table, and said: "Old Li, according to this charter, you recruit a group of civilian workers. The number does not need to be large, a hundred or so will suffice."
Already."
This kind of cement has good acid and alkali corrosion resistance, low early strength, and the strength increases quickly under high temperature curing. It has strong water absorption and low heat release when used. It usually takes 2 to 3 months to reach the standard strength, and its frost resistance is not as good as ordinary
For cement, the curing period takes 20 days.
Emperor Wen of the Sui Dynasty also issued tax exemptions and tax reductions, but these were short-term and temporary, and did not alleviate the long-term trend of the taxation system's efficient extraction of private wealth, resulting in the country becoming rich and the people poor.
Seeing that he couldn't be persuaded, Eunuch Li also gave up. The Zheng Kezang he knew always had his own ideas. He often seemed approachable, but in fact he had his own opinions. Even if Zheng Jing came, he might not be able to solve the things he believed in.
He simply won't say anything, as long as His Highness the Governor knows what he is doing.
"Your Highness Jian Guo, I haven't read many books, but I also know how Emperor Yang of the Sui Dynasty caused great chaos in the world. It was the massive construction projects that made people's livelihood difficult. Your Highness Jian Guo, please think twice." Eunuch Li said with worry.
When Emperor Wen of the Sui Dynasty was the Prime Minister of the Northern Zhou Dynasty, he saw the importance of finance. The reason why the Northern Zhou Dynasty was able to destroy the Northern Qi Dynasty was because the Northern Qi Dynasty had a chaotic population statistics and a huge reduction in tax revenue - the Northern Qi Dynasty stipulated that bachelors' taxes would be halved, and many people did not register their marriages. The Northern Qi Dynasty
The court had no choice but to reduce tax revenue by more than 60%.
What was a "big deal" in those days? Infrastructure projects and foreign wars, of course.
The preparation method is also simple. Wash the above materials, dry them in a fire pit, and grind them into powder. They can be blended and ground together, or they can be ground separately and then mixed evenly. You can use the most common stone grinder.
Grind finely.
As he spoke, Eunuch Li beat his chest. Although Zheng Kezang had made a lot of money from the British guy Thomas these days, he earned more and spent more. He watched the money disappear every day. Eunuch Li was very
Heartache.
The above ground materials are mixed together in proportion to form cement, also called mixed cement.
The past has become a memory. Thanks to the project manager who treated him like a beast, Zheng Kezang still vaguely remembers how to make cement.
The Sui Dynasty can be regarded as the death of its second generation, and the people rebelled only when they could not survive. This "prosperous age" had nothing to do with the people.
However, Sima Yi saw the trick: it was precisely because the Shu Han adopted a strict management system and squeezed these places so hard that they rebelled. Wei should not continue the mistakes of the Shu Han and should leave a certain amount of ambiguity to these people.
space, so he dissuaded Cao Pi.
This is because the so-called "founding of the emperor's prosperous age" by Emperor Wen of the Sui Dynasty is actually an extremely abnormal situation of the country becoming rich and the people poor.
Eunuch Li thought to himself: What is cement? Is it the silt in the water? What can this thing do?
With doubts, Eunuch Li continued to read, and the more he looked, the more frightened he became.
How to make it is very simple. Zheng Kezang remembered that the recipe is: clay bricks, various pottery fragments, various ceramic dishes fragments, and various refractory materials, such as fragments of jars, basins, etc., water-quenched slag (iron-making
The waste slag in the furnace is directly put into the cold water pool and quenched), and the slag ash (the residue after burning various coals), 75% of each of the above materials can be taken separately, or they can be mixed together to take a total of 75%.
"Old Li, do you know about glutinous rice juice? This thing can replace glutinous rice juice to stick to bricks. With it, we can build extremely strong city walls and save food. In the future, we will no longer be afraid of waste when building large-scale construction projects in our country.
We have food." Zheng Kezang, who was in a good mood, gave him some popular science advice.
Seeing Eunuch Li's reaction so violently, Zheng Kezang felt that he should give in appropriately to prevent the old eunuch from getting mad at him, so he comforted him and said: "Don't panic, Old Li, you have spent this money and you will make it back sooner or later.
This is a business that makes a lot of money every day. Otherwise, the monthly payment will be changed to 400 Wen, and other things will remain the same."
After Emperor Yang of the Sui Dynasty came to the throne, such abundant finances gave him a great illusion. In the fifth year of Daye (609 AD), there were 8.9 million households and 46.02 million people in the country. In this year, the Sui Dynasty
Emperor Yang launched a war against Tuguhun. During the Zhenguan period of the Tang Dynasty, the total number of households in the country was only more than three million. By the Kaiyuan period, the number of households was almost the same.
Emperor Yang of the Sui Dynasty had very good military discipline. He was also a military commander, and he also issued tax reduction measures. But what are the land statistics for this year? 5.585 billion acres, which is already the same as the actual number of acres.
The difference is ten times. This means that the common people have to pay so much land tax, which is unbearable among the people.
In the eighth, ninth and tenth years of Daye, Emperor Yang of the Sui Dynasty launched three conquests against Goguryeo. Disasters occurred in various places. The Grand Canal was opened. Military operations and the construction of palaces required additional taxes and levies. Finally, the critical point was exceeded for the people, and so happened
Society collapsed, uprisings occurred in various places, and officials rebelled one after another.
After thinking so much, Zheng Kezang also realized that it was not advisable to make the country extremely wealthy and the people poor. Although this was still far away from him, he was only the temporary island owner now, and he had to go through Feng Xifan's test if he wanted to become a full-time official.
