Similarly, if there is a problem with the employee, it is best not to come to him directly to deal with it. Even if the employee is right, it is actually difficult for him to deal with it. If it is handled, although it will increase prestige among the employee group, it will bring harm to the management.

Just like in ancient times, I wanted to sue the emperor, I had to beat the board before I could see the emperor.

I shook my head. The improvement of the system depends on the environment. Take your time crossing the river by feeling the stones.

It's already the third day today. Wang Hongwen has run away for three days with his money and has not come back yet. Yang Chuntao also ran away to the county to sell vermicelli. The initial sales were pretty good, but the vermicelli is expected to be nearly 100,000 kilograms. This is too large. Most of it can be sold before the New Year. That is a happy event. In theory, vermicelli can be stored for one year, but the best time to eat is within half a year. After a long time, vermicelli will easily be found to break by itself and reduce toughness, which will eventually affect the taste and smash the sign.

If it really doesn't work, the cement factory will also find a way to solve some of the problems, so it will not cause the hearts of the entire Jiaoshan villagers.

The opening plan for tomorrow will continue as usual, and the initial construction of the cement plant has also reached the end stage. Construction can be started after the equipment is installed.

Masons and stonemasons are different from those who rely on physical strength, but have more technical jobs. The same is true for carpenters. Technology is the foundation. As long as they have the skills, they can find food to eat during that period, and it is also very important to teach technology that can make a living.

To summarize it, it is actually not easy to train a skilled technical worker.

These masons will leave a few of them to finish the work, and the rest will be taken out the day after tomorrow. They will build a large warehouse in the steel town and dump the goods in that place later.

Then he will go to the city and various county towns. If the plan can keep up, these nearly 30 technical workers will be incorporated by him and form a small team. It is a small subsidiary to serve him.

At the same time, he is now going to set up a prefabricated plate factory. Prefabricated plates are floor slabs used in early construction. Because they were processed and molded in the factory and transported directly to the construction site for installation, they are called prefabricated plates.

Two thousand years later, it was basically replaced by reinforced concrete that was watered on site. It was still very interesting in the 1980s. As long as the building was built, prefabricated boards had to be used, even small bungalows had to be used. It could be continued in the 1990s, but in two thousand years, it was only suitable for rural markets, even in rural areas. The frame houses could not use cement boards.

He vaguely remembered that the price of prefabricated plates thirty years later was about 100 yuan. If the specifications and the prices of various raw materials were ignored, the price of prefabricated plates was about one-fifth of the price of cement, and the transportation cost must be ignored here.

So, after all, cement is now worth 40 yuan per ton, and prefabricated boards should be eight yuan per yuan, but the real price is close to ten yuan per yuan. After all, the price of prefabricated boards is a bit inflated. But this is a good thing for him.

As early as a month ago, when the cement factory was launched, he investigated the prices of prefabricated plates, processing data, etc.

Ignore the cost of that little steel bar, and the rest will be used: water, cement, river sand, and stones.

Start with a good quality formula, that is, the proportion of cement consumption is larger. The mix ratio is: water 0.38: cement 1: river sand 1.11: stone 2.72

Calculated based on the volume of commonly used concrete in the industry, water is required: 175kg, cement: 461kg, river sand: 512kg, stones: 1252kg. The total weight is 2400kg, and the general standard is 2100-2600kg.

For the other poor formulas, only 340kg of cement per cubic meter, use less than 80kg of cement, and then the proportion of river sand will increase. But because cement is now self-produced, it is better to follow the quality route. After all, this is processed to live in people, and quality is the first key.

The current formula has become the standard for reinforced concrete in later generations, and the total material mixing weight is 2400kg.

In terms of cost, water is not expensive. Cement is calculated at 25 yuan per ton, 461kg is about 11 yuan and 512kg of river sand. Currently, the prices of river sand and cement are dozens of times different. The reduction and increase river sand. The profit in the middle is very large. However, for later generations who experienced earthquakes, quality is the key, so they will insist on the proportion of cement use.

The stones cost about 1 yuan and 3 cents of concrete, and the total cost is about 13 yuan and 3 cents.

Currently, the specifications of ordinary cement prefabricated plates are 3 points and 6 meters in length, and no more than 4 points and 2 meters at most. The width is calculated by holes. A hole is 10 cm, generally 4 or 5 holes, that is, 40 cm or 50 cm wide, and the thickness is generally 12 cm or 15 cm.

The prefabricated plate costing 10 yuan is 3 points, 6 long, 40 cm wide, 12 cm thick, and the diameter of the hollow hole in the middle is 6 cm. Calculated, the overall volume of the prefabricated plate is 0.17 cubic meters. The volume of one hole in the middle is 0.01, and the four holes are 0.04 cubic meters. The resulting volume is 0.13 cubic meters.

Compared with the previous volume ratio of one cubic meter, the cost price of a prefabricated plate of standard specification is 1 yuan, 70 cents. The weight is 312kg. After the water is evaporated, it is about 300kg. This is calculated based on ordinary cement boards of 3.6 meters. If corners are cut, the weight and cost will decrease.

In addition, 4 to 8mm steel bars can be selected according to the load bearing. According to later national standards, first-class prefabricated plates with a length of 3.6 meters and a width of 0.5 meters should have 10 steel bars with a diameter of 4mm, and 4.2 meters should have 10 steel bars with a diameter of 5mm.

The current specification is 40 cm, only 8 steel bars are needed, divided into five groups, one left and right sides, and two in the middle three groups, with a spacing of 10 cm.

The diameters of steel bars are different, and the weight is very different. A 6 mm steel bar is more than twice the heavier than a 4 mm steel bar. Because the price of steel bars is relatively expensive, cutting corners is mainly in the two aspects of cement and steel bars. If these two are missing, then prefabricated plates are life killers!

Because the length is only 3.6 meters, just choose 4 mm steel bars. However, Fang Dajun still plans to choose 6 mm, weighing 0.222kg and 3.6 meters per meter, which is equal to 0.8kg. There are 8 pieces in total, and 6.4kg steel bars are needed. In fact, it is not only because a little bit of them will be exposed at both ends, which will take about 7 kg in total. The current price of steel bars is 320 yuan per ton, and in the later generations, it is about 4,000 yuan, an increase of 12 times.

320 per ton, then every kg is 32 cents, which will cost 2 yuan, 2 cents and 4 cents. The price of steel bars alone will exceed the remaining cost of 1 yuan, 7 cents and 2 cents. It is indeed a bit scary. If he chooses 4 mm steel bars, then the cost of steel bars is only 1 yuan.

But the same thing is said, safety is finally Taishan. Of course, if you choose 8mm steel bars, it will cost more than four yuan. With the cost, it will cost more than six yuan. This does not count the cost of artificial sites and equipment. If you really choose 8mm, you will be kneeling down, which is a waste of work. You can't make money at all, and it is a big waste.

So choosing 6mm is OK. This has exceeded the standard thirty years later. The total cost is about 4 yuan. A prefabricated board of 10 yuan is equivalent to making 6 yuan. In fact, there is not so much. The purchased raw materials need to be transported back. In addition, the workers' wages and electricity bills for the site equipment all require costs, and the failed products must be included.

Overall, when he uses prefabricated boards according to his standard, each piece is about 4 yuan in profits, which is directly a kneel compared to the profits of honeycomb coal.

But we still have to do it, just like cement factories, the accompanying significance is very important and it is related to its future industries, so the prefabricated plate factory must start.

And time is still tight, because the cement factory has to use prefabricated boards when building a building. He doesn't want to guard Baoshan, so he goes out to buy it. The prefabricated board production equipment is very simple, as long as there is a mixer and an internal vibration floor machine, it's OK.

But he seriously suspected that there is no internal vibration floor machine now, or even a simple version of professional floor machine. This kind of equipment is a fool-proof operation, just cram the mixed raw materials, which saves the trouble of hand-made molds.

I'll ask XCMG to consult this question tomorrow. If there is really no, then I'll make it myself. The machine is not complicated. Its function is to professionally manufacture prefabricated boards. As for patents, it's probably a bit scam. Please consult it then!
