The hot sales of red bricks and coal made Gongsun continue to smile, and the shriveled treasury gradually began to be abundant. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Also rich in the people, taken from the people, Gongsun Xu is very satisfied with such a cycle model, the money is still the money, and it has not circulated to other places, the city lord's mansion in Xiangping City began to have money, and the people who work below are also rich, and their lives have been greatly improved.

The sale of red bricks and ondols, as well as coal, is a matter of benefiting the country and the people. With the ondol, at least this winter will reduce the number of people who have frozen to death.

The bitter cold in eastern Liaodong, every year in winter, there will always be so many 8,000 people because of heating or other problems can not survive the winter, with the kang this kind of item, a big kang can sleep seven or eight people, or even squeeze it, can sleep more than ten people.

In this way, if you are a family, you can basically solve the problem of living in a big kang and don't have to worry about anything else.

The people in the city are easy to say, and the people outside Xiangping City who are begging for a living are also easy to solve.

After a few large kang kang were first built in the villages near Xiangping City, the people in those villages would naturally consider the matter of building a fire kang.

As long as more than half of the families in each village have built a kang kang, it will not be a big deal to survive the cold winter.

Gongsun Xu knew best in his heart that whether it was coal or red bricks, his cost was nothing more than the wages of those workers, and a large part of the work was free for slaves.

Coal mines belong to him privately, and the coal produced costs nothing except that some money is needed in the process of transportation.

This is especially true for burning bricks, except for the money used for coal when burning bricks, the rest does not cost any money.

The construction team out of the city lord's mansion is all profitable, and every time a red brick stove is built with a fire kang, the engineering team will have at least 20 or more five baht in the account.

It was the craftsmen who were responsible for helping the poor people build a fire kang, and for each fire kang they had to pay a fee of two five baht coins to Gongsun Xu's city lord's mansion.

The two projects are all Wanli projects, and the two projects together, that is, in a month, hundreds of thousands of five-baht coins have been hoarded in the treasury of Gongsun Xufu.

Unlike gold and silver, the five-baht coin was the most valuable hard currency in the Han Dynasty, and the five-baht coin was the most important in all transactions.

In this era, the king took the initiative to give 10,000 taels of gold, which was actually copper, and real gold and silver items were very rare.

Transactions are generally based on five-baht coins and silk cloth, and this time Gongsun Xu was able to harvest so much five-baht money, which also made Gongsun Xu feel quite surprised.

The matter of building a brick structure house was also put on the agenda, and the sale of the kang was so successful that the red brick could be said to have been accepted by the people of Xiangping City in a few days.

If the brick structure of the house is launched at this time, I believe that there will be countless Xiangping people flocking to it.

But what! This year, Gongsun Xu does not plan to launch a large number of brick houses, only a few households.

No matter what time it is, it is rare and expensive, and those who can live in pure red brick structure houses in advance must be either rich or expensive, and they are all big families or big businessmen who have such a strength.

Only a few typical houses are built, one is to make a reference for later advertising, and the other is to raise the price of the house to the highest, which will also have a certain impact on the real estate he wants to engage in in the future.

In addition to building the barracks, he wanted to build a large, brick three-story supermarket on the spot where the barracks were replaced.

For this project alone, the amount of red bricks needed has reached an astronomical amount.

Zhao Yun and Gongsun Da and the others had a certain understanding of the value of these red bricks after living on the fire kang, and they felt very puzzled when they saw that Gongsun Xu was actually doing what to lay the foundation and bury those red bricks underground.

Now those red bricks are all sought-after goods, and the most important thing is that when building a house, they have never seen Gongsun Xu lay a foundation like that.

After Gongsun Xu developed the red bricks, Gongsun Xu began to study the cement of the soil method.

Gongsun Xu remembers very well that most of the things like cement are fired or configured.

Slag ash (i.e. the residue after the combustion of various coals, the more fully sintered, the better the quality). Sort out the white slag and red slag, remove impurities and sand, and then wash, dry, grind, and pass through a sieve.

This kind of thing brick factory produces a lot every day, and I have been worried about how to digest those cinders before, but now I directly pull those cinders to a professional place to carry out cement supplies.

Lime should be quicklime, and the new kiln is better. The lime block is sprayed with water to make it pulverize itself, and there are a lot of lime mines in Xiangping, and the limestone that comes out becomes quicklime directly after a certain period of calcination.

Lime is a very versatile thing, and it has a wide range of uses. One of the most important is to prevent a widespread outbreak of the plague.

After the lime is sprinkled on the ground, it will produce high temperature after encountering water to kill bacteria and control the concentrated outbreak of epidemics.

After the gypsum is heated to 107~170C, it becomes mature gypsum.

Crush and grind it finely, then fry it in an iron pan. Wait until the gypsum powder no longer bubbles in the pot, has no water vapor and turns from white to yellowish-gray.

When these three things are mixed together, it is the cement of the soil method.

Gongsun Xu got the bricks and earth cement, and he felt that these two things could not only change the architectural pattern of the entire Han Dynasty, but also enlighten the future situation of the military and several other things.

After the development of cement products, Gongsun Xu did not want to greatly promote cement, this kind of thing across this era must be firmly in their own hands, this method of production, and even Gongsun Xu completely separated several processes to operate.

There was a steelmaking blast furnace in Liaodong a long time ago, and it was a steelmaking production area built in the middle of the Han Dynasty, but in the later period, no one managed it, and this steelmaking blast furnace was scrapped.

Liaodong is bitter cold, there are many cold days, and most of the masters of steelmaking are southerners, and they are not used to living in the north, so although there is steel and cheap labor in Liaodong, the blast furnace has also been stopped.

It is precisely for such a reason that the equipment of several sets of steelmaking furnaces is cheaper for Gongsun Xu, saving Gongsun Xu the money to buy these steelmaking furnace equipment.
