Everyone didn't dare to step forward at first, who had the leopard to dare to doubt Chief Huang's words, but as Huang Shi began to call out the names of Xiaohong and Li Chengpeng, the people who were called had to step forward one by one and began to measure the thickness of the bricks.

Huang Shi crossed his hands and watched them measure there, he was very confident, and sure enough, after each of them measured a few pieces, they all reported that they were exactly the same, and the size of each red brick was 240 mm in length, 115 mm in width, and 53 mm in thickness.

Of course, he knew that these bricks were all standard bricks that he specially produced after the brick factory raised the price by 25%, and the original boss offered 35%, but when he saw Huangshi making a picture of leaving, he called him back.

After the back and forth between the two sides, the most stubborn to add 20%, and said that if there is a wrong, then the brick factory will have to compensate, on the contrary, if the quality is completely in line with the standard, then Huangshi has to give the brick factory a reward.

This brick factory was found in Huangshi with great difficulty, because now the state has strictly prohibited the burning of bricks, and only in very rural places is someone secretly doing it, so Huangshi also ran to the countryside a few days ago, and finally found it in this corner of Fuqing.

Mainly because the bricks bought in the cement shop in the city will be smaller, and the size will be uneven, the level of this subordinate is already poor, if the bricks are not standard, how can they possibly get it, so Huangshi has to spend money again.

Because he had already accepted it once before, and each brick was indeed almost a penny, Huangshi thought that he would have to buy bricks from him for at least a long time in the future, so he generously gave a 5% reward.

Then he placed a big order, which he was going to prepare for the construction of the building hall in the back, the amount was very large, but this time he asked for it not so urgently, and said that he would let the boss work slowly and carefully, and he was afraid that he would not have time to accept it in the next stage, so he remembered Xu Fei and Li Tiejun.

Xu Fei had already left his post some time ago, and after inspecting several small factories around Fuzhou, he was sent by Huangshi to Shanghai to find investment consulting companies to evaluate the credit rating of these companies and prepare for the acquisition of parts for the future production of fire cap guns.

So he can only ask Li Tiejun to do these things, and the pre-accounting of materials can add money to the designer he hired to help calculate, but procurement, acceptance, and warehousing are very time-consuming, and there is really no need to do everything himself.

Just like his current purchase of daily necessities is entrusted to Gao Yifei, in addition to giving a fixed salary, it is also a good way for them to receive some kickbacks, so that they will be motivated and dedicated to doing things.

Because he often hears Jiang Hualong talk about some shady things in the construction industry, saying that there are many fake and shoddy products in the current engineering materials, some of which are not standard, and some are directly cutting corners, so if you want to get the basic standard, even if it is a brick, you have to add money, at least about 20% more than the lowest-grade garbage bricks.

And those screws, steel or something is even more amazing, if you add 30% to the most garbage strip steel, it may be qualified steel, but this is only qualified, and if you want high-quality steel, then you have to float +50% or even double, and even some luxury equipment, accessories, several times more things have, but these high-priced profiles are indeed worth the money.

Speaking of this, Lao Jiang also patted his thigh, sighed for a long time, and said, "The most expensive is not necessarily the best, but the cheapest is definitely the worst, so what should the poor ghost do, choose the lowest price, and then choose an item that is about 30% to 50% higher than this reserve price, which is basically an ordinary goods that can be used." ”

"Does anyone buy the worst one? Not afraid of accidents? Not afraid of death? "Huang Shi is very puzzled, didn't he hear that Ning is greedy for the road, Mo is greedy for the bridge, this worst material is not used to build a house!

"Of course, there is, the lowest, only temporary projects are used, because it does not require a time limit, and it can be scrapped in the previous year, and there are many such projects, such as temporary sales department, temporary mobile housing on the construction site or something."

Of course, Lao Jiang still didn't say a word, if this capital has a 50% profit, it will take risks, there are no people in this world, and there are a few people who are engaged in real estate.

"Oh, that's right." Huangshi was greatly touched, and he decided to let Li Tiejun go to the big factory to purchase those large quantities of steel and cement, because the wholesale on the street is even if the money is added, and it is not necessarily genuine, if there is a case, not only will his face be hit, but also the construction project is related to human life, so he must not be cautious.

……

Huang Shi led them around the brick wall made of tens of thousands of red bricks, and dozens of gray cement bags appeared behind them. This is the cement that Li Tiejun traveled hundreds of kilometers to the Shunchang Cement Factory to procure, and Huangshi hoarded hundreds of bales in the shipyard at once, and only a small part of them appeared here.

"What is this, guess what?" Huangshi asked them, pointing to the cement that had been built into a small jar.

Seeing that they were all shaking their heads, Huang Shi said, "Then you can come and see for yourself." ”

"Shunchang Cement Plant...... Ordinary Portland cement ......" Li Chengpeng, who was standing in front, shook his head and read the words on the cement bag, but he had never been in contact with this construction business, so he said that he only knew these words.

Huang Shi looked at the others as well, they were all at a loss, as if there was only a little old man who had something to say.

"Lao Gan, what do you say this is?"

Jiang Laogan also let go, that is, he said it wrong, and he would be laughed at by others, but he couldn't let the chief's questioning be cold, so he replied to Huangshi, "The chief wants to build a thick wall in these pits?" ”

"Yes." Yellowstone nodded.

"Then I only saw the red bricks here, but I didn't see the plasters for building the walls, so I wonder if they are the plasters used in the sky." Jiang Laogan looked at Huangshi worriedly after speaking.

"Well, what Lao Gan said is very right, this is the plaster, it stands to reason that you should all be able to guess it?" Huangshi is very strange, for something so simple, others can't see it.

Jiang Laogan didn't look at the others, but he knew what they were thinking, so he said, "Chief, because the plasters we used to build the walls in the past were all white with only a little gray, unlike this ......one, which is all gray."

After speaking, he also raised his index indicator to show Huang Shi, because there will be some gray powder scattered on the outside of the cement bag, and when they stepped forward just now, they also lightly dipped their fingers to check it, but they saw that it was all gray and powder, so they were a little uncertain.

In fact, the ancient Chinese brick-laying technique has been very ingenious, can build various styles of brick walls, there are thin and thick, high walls and low brick walls, there are inward inclined side foot walls, there are also outward inclined styles, at the same time there are curved walls, built into cylindrical shapes, and more ancient such as the Great Wall, as well as large stone walls.

Studies have shown that in China during the Tang Dynasty or before the Tang Dynasty, there was no lime, only white ash, and the brickwork walls were made of cohesive loess mortar.

For example, the brick walls of the Tang Dynasty were all built with yellow clay, and the brick walls are strong and do not collapse to this day, which has become a strong evidence for identifying and analyzing the construction age of the brick towers. For example, the towers of the Tang Dynasty that we can still see now are all made of pure yellow clay as mortar.

In the Song Dynasty, the bricklaying technique was further matured, and lime was produced, and after using lime and yellow clay and water to become a kind of white ash clay slurry, so that the tower was built with mortar, which was more solid and durable. Try to look at the large number of pavilion-style towers built in the Song Dynasty, and their brick-shaped bodies are all made of white ash and yellow clay slurry.

After the Song Dynasty, to the Yuan and Ming dynasties, the masonry used pure "white ash mortar", which was more solid and durable, such as the city walls all over the country, the Great Wall, brick walls, etc., all kinds of walls were all made of white mortar, and no clay was added to the mortar, but pure white ash. Especially in the Ming and Qing dynasties, some large brick and stone buildings used a large amount of white mortar. The production of white lime solves a large problem of a large number of masonry masonry.

Later, in the Qing Dynasty, in the official buildings and individual important buildings, glutinous rice is often boiled and added to the lime, and it is used to build brick joints, so that the mortar is very hard after drying up, and it cannot be broken with an iron pickaxe. In any case, the number of royal buildings is still a minority, and it is still possible to use glutinous rice milk in individual projects, and it would be a waste if it was used in large quantities.

In addition, lime is a white or gray block, which will only become a paste after adding water, and there are also clay, quicklime, and sand as a formula to form a triple soil cement, so this real "cement", these Ming Dynasty natives naturally can't guess.

"The composition of the cement we have above is ......, and there are similar things here in you, I wonder if you have ever heard of the person 'Ge Hong'?" Huang Shi especially took a look at Li Chengpeng, and found that his expression was no different from the other mud feet on the side, they were all waiting for explanation.

This Li Chengpeng doesn't seem to have a wide range of knowledge, Huang Shi thought to himself, he is not as good as Mu Yi at this point, no wonder one is a student, the other is a show talent, thinking of Mu Yi, he thought of Zhou Mingrui, Wang Xiaoya and Ning Zhiyuan, so Huang Shi suddenly had no mood to popularize historical and cultural knowledge for them.

Ge Hong of the Jin Dynasty wrote in "Hug Puzi? Jindan" mentions the Liuyi mud, and they cultivators use it to seal the furnace when refining the pill. Okay, I'll start teaching you how to sift sand, how to mix mud, and how to plaster. So Huang Shi said it hastily and began the formal training work.
