Polant cement is a building material invented in the 19th century, because the color and strength of the cement produced are similar to the stone on the British island of Polant, and it is named Polant cement.

Ahem, where would a thick-skinned person like Liu Ximing care about these, he named it stone slurry with a wave of his hand, and took it like a slurry after adding water, and like a stone after condensation.

Liu Ximing, the limestone needed to make stone slurry, had ordered it in Fucheng before, and clay was available everywhere in the village.

The production process needs to first grind the raw materials into powder and then stir them evenly, so Liu Ximing specially asked the stonemasons to make a few grinds for grinding, and after these raw materials are fired out of the kiln, a small amount of gypsum will be added to grind them into powder, so that they can be regarded as truly formed.

It happened that Liu Ximing bought a few cows when he built a house before, and there was no farm work to do at this time anyway, so he brought them over to grind first.

Li Xi heard Liu Ximing ask about the firing situation, and replied curtly: "Second young master, I will burn it again according to your method, and this thing has been burned, but it doesn't seem to be as hard as a stone as you said, young master." ”

Liu Ximing suddenly scratched his head, and he remembered this thing by himself, but he wanted to count on these rural craftsmen to get this thing done by themselves, and Liu Ximing felt that it was a little unreliable.

He had no choice but to bite the bullet and say to a few craftsmen who were looking at him with blank eyes: "Let's go, lead the way, let's go and see what is wrong." ”

Li Xi and the others immediately had a happy face, the owner didn't blame the big guys, and a group of craftsmen hurriedly took Liu Ximing and others to a kiln specializing in firing cement to check.

Liu Ximing picked up a lump of calcined powder, and compared the solidified materials after adding water and stirring them, these things looked similar to the cement he had seen from the outside.

He picked up the dried magma sample and broke it vigorously, and with a bang, he kneaded it into several petals.

……

This thing is a little hard when mixed with water, but why is it so brittle? Liu Ximing was also puzzled.

When he went to the kiln to see it, it suddenly dawned on him that these craftsmen also put the raw materials directly into the kiln to calcinate them like burning bricks, and they did not stir them evenly at all, so that the raw materials did not react completely, and the materials manufactured were of course hard but not hard.

Liu Ximing remembered that when he was looking for information before, he saw that in order to ensure the uniform calcination of powder raw materials, the best way is to use a rotary kiln to tumble and stir at the same time as calcination, but this thing is definitely not available now.

In this way, there is only a vertical kiln, which is to input raw materials from the top, and air is introduced into the middle of the vertical kiln, and the raw materials are blown back and forth in the kiln to achieve the purpose of mixing, and at the same time, the air can improve the combustion efficiency in the kiln and speed up the reaction of raw materials.

Now there is no blower, but you can use the bellows, Liu Ximing quickly told Li Xi and others his thoughts, urging them to transform the brick kiln into a kiln as soon as possible.

On June 14, Li Xi and others rushed over to report the good news, saying that they had burned the kind of stone slurry that Liu Ximing said.

These craftsmen had built a wall out of stone mortar mixed with bricks two days ago, and now it has dried, Liu Ximing motioned to a young man among the villagers to take a sledgehammer and smash it hard, boom, only to hear a muffled sound, this young man was almost injured in the arm by the hammer that came back from the shock.

"Wow", the onlookers really saw it, and the entire wall was still intact after this hammer, and they all immediately exclaimed.

Hahaha, Liu Ximing laughed heartily, and he lived up to his heart, he could build a house quickly starting today, just after completing the dormitory, blacksmith shop, carpenter shop and other key buildings.

"The firing of stone slurry is a secret at home, except for a few of you who know all the recipes, you must not tell the rest of the people, otherwise you will not be spared." Seeing that the firing was successful, Liu Ximing hurriedly pulled Li Xi and others over and admonished.

As for how long it can be kept secret, it's hard to say, but at this stage, everyone eats and lives in the village, but there is no risk of being snooped on by outsiders, and when there are conditions in the future, a few factories will be built, and all the steps will be separated, so as to keep the secret as much as possible.

It's not that Liu Xi is destined to cherish himself, after all, burning stone slurry is a highly polluting industry, he doesn't plan to put it in his own village, if he wants to find a home in the future, there is an exclusive secret recipe, isn't there also a negotiating advantage.

~~~~~~~~~~

"What, you're just fooling around, is this a panic with a lot of money or whatever, it's absolutely not okay to do this."

A roar came from the main house of the Liu family, Liu Ximing's uncle Chen Yiding spent more than ten days settling down the affairs of the private school and rushed over, who knew that after he listened to Liu Ximing excitedly talk about his ideas about village planning, he immediately changed his face, and he kept walking around the house with an angry face, while counting Liu Ximing.

Liu Ximing felt a little surprised, in his impression Chen Yiding was a gentle temper and a good communicator, so the last time his mother said that she wanted to invite him to help with the housekeeper, he agreed, who knew that he would become what he is today.

Chen Yiding saw that Liu Ximing was sullen and didn't speak, and said angrily to Liu Chen: "Little sister, he is a half-old child, you can't just let him mess around?" ”

"The second child was good in the past, and the family was almost unable to open the pot before, and it was only developed by him, and I am used to letting him be in charge." , Liu Chen was also frightened by the eldest brother's roar, and whispered a little weakly.

Chen Yiding eased his complexion at this time, lowered his tone and looked at Liu Ximing and said: "If it weren't for my uncle wanting to talk about you, you have also suffered a lot in the past six months, and it is really commendable to be able to support family affairs." But after all, you are young, and you don't know how hard and thrifty you can last long, do you know how many rich families I have seen have been ruined because of ignorance of thrift. ”

"Isn't it a fantasy that you just said that all the land between the village and the wharf will be converted into private houses, and it is all good and fertile land. If you really level it and build a house, where will you find land to feed so many people, not to mention the time-consuming and laborious reclamation of wasteland, and there will not be much output in the first two years, isn't this asking for trouble? Besides, all the villagers you have recruited are penniless, and even if you build so many houses for them, God knows when you will be able to get you. ”

"Uncle is angry, these nephews have considerations, you listen to me in detail." Liu Ximing saw that Chen Yiding was in a hurry, and knew that he was kind enough to consider himself, so he couldn't be hard-topped, so he could only vaguely say his judgment about the general trend of the world and other information, hoping to persuade him to support him.

Chen Yiding stood still after listening to the beard in his left hand, with a shocked expression as if he was thinking, and after waiting for a while, he shook his head vigorously and said to everyone in the room: "It's really nonsense, how can children worry about the sky." Now that the Holy Son of Heaven is in power, the eunuchs and traitors have been swept away, and the important positions in the court and the central government are all held by our generation of scholars. ”

"You are often at home, and you don't know the news of the imperial court, so you will inevitably be a little lonely. As everyone knows, since this year, Chen Qiyu, the right attendant of the military department and the right servant of the imperial history, has repeatedly broken the thief army, and the so-called bandit leaders such as the stars and the tigers in the thief army have been punished, and I am afraid that the bandits will be able to quell the bandits in less than two or three years. ”

Liu Ximing saw Chen Yiding say that in the end, he became more and more impassioned, quite a little ridiculous, uncle, uncle, where did you get these mysterious confidences.

As for the Zhengying Dynasty, it was these so-called righteous men and gentlemen who disregarded the country and only cared about their own interests, and made Comrade Xiao Zhu confused, until they finally came to their senses and sighed that the Manchu Dynasty could kill both civil and military forces.

But if you think about it carefully, this is probably the general impression of the world now, who would have thought that the Zhu dynasty, which had ruled for more than 200 years, would collapse in only ten years.

In addition, now Li Zicheng, Zhang Xianzhong and other thieves are still in the stage of the rogue war, they only know how to coerce the people, rob the rich, do not recruit scholars to join the team, and do not have a solid base to confront the central government.

Moreover, at the end of Chongzhen, it was not completely impossible for the Meng Dynasty to survive for a long time, such as Chen Qiyu and Yang Sichang, who almost wiped out the peasant army, but in the end they fell short due to strategic miscalculation, Qing invasion and other reasons.

As a traverser, Liu Ximing naturally has a clear understanding of the general trend of the world, but he is a little short of words about how to persuade Chen Yiding.
