Cement is a very important raw material in the construction industry, and its types are also very large. There are ordinary cement, special cement, and special cement. The ordinary cement is the simplest and the most variety. There are also many kinds of special and special cement. , Only need to change the raw materials and manufacturing process, the cement produced will be different.

Due to the limitation of raw materials and technical conditions, what Li An can invent now is the most common cement in later generations. In some properties, it is not even as good as the ordinary cement in later generations, but as long as it is cement, even if the performance is slightly worse, It is much stronger than ordinary dirt.

Most of the limestone work is done by hand, but the grinding step is the machine ’s responsibility, because some limestones are too hard, and if they are hit by a hammer, it is difficult to break them completely. Only dedicated Only by grinding the machine can the limestone be completely crushed into the required powder.

These ground powders can be shipped directly to the imitation porcelain coating workshop or cement workshop. In addition, there are many grinding equipment in the following two workshops, because both cement and imitation porcelain coating are powder-like Small particles, but limestone, clay and other materials are in the form of blocks, and there is no way to produce products without thorough grinding and crushing.

Clay is relatively common in the local area. The brick kiln workshop is built in the place where the clay mine has the best quality. Therefore, it is not difficult to obtain the clay block, and it can be directly transported to the cement workshop for grinding.

In addition, in order to improve the quality of cement, various auxiliary materials can also be added. If you can obtain it, add a little. If you don’t have it, you can only count.

Looking at the lime powder that was ground into powder, Li An not at all approached, but left with his subordinates, so as not to cause the lime powder to form dust due to the movement of people. Affecting the health of yourself and your people will cause a little waste of powder.

When walking, Li An travels slowly, because of the continuous transportation for many days, a shallow lime powder has fallen on the road surface near the lime mine. If you walk too fast, it will cause dust.

In order to prevent more and more powder from accumulating on the road surface, the road surface should be washed with river water every few days to wash away the dust on the road surface. If it rains, it will naturally not need to be washed.

Rinse the road with river water. The washed sewage is not directly discharged into the river, but there is a special sewage river, which leads directly to the harbour not far away.

Although sewage is harmful, the sea is vast and has a very strong self-purification ability. A little pollution will not cause too much impact on the sea and is negligible.

Fortunately, there is no wind today, otherwise, a series of fresh wind will blow the dust on the road to the body of the person, it will be very uncomfortable.

In Li An ’s previous life, he always had to go through the road near the cement factory when he came home, which was a kind of torment, because there are many vehicles transporting cement in and out of the cement factory, and each vehicle will always leak a little cement powder. The accumulation is a large amount. After many years, let the road surface near the cement plant pile up a large amount of cement powder. Even if it is rainy, the impact will not have much effect. The nearby rivers are all cement powder. At the bottom of the river bed there is at least one meter of a mixture of cement and mud, which is particularly disgusting.

Usually people coming, people going, everyone can smell the smell of cement, if you encounter windy weather, it will be particularly miserable, a lot of cement powder assaults the senses, can choke people’s suspicion of life, many times , Li An would rather go more than ten minutes, rather than take this path.

However, what is strange is that this dirty road is actually the largest red light district in the city, with various shampoo rooms and foot wash rooms all over. There are many factories nearby, and there are plenty of customers. In short, there are always a lot of people engaged in dirty transactions beside the dirty roads.

After getting on the train, Li An continued to go to the cement workshop not far away to inspect the situation there and see the first batch of cement produced by the cement workshop.

The pavement inside the cement workshop is similar to the pavement of the lime mine, and it is a thin layer of powder, which can fly up when the wind blows.

Because these powders are unavoidable, all the road surfaces of the cement workshop must be cement floors. Only in this way can the water be flushed. If it is a dirt road surface, it will be damaged if washed with water.

“Minister Li, the first batch of cement has been produced, would you like to see it.”

The leader of the workshop came to accompany Li An to inspect and said.

Li An looked at the front and said, “The craftsmen are all having lunch. Let’s take a look at one by one, in order, don’t worry, right, have you eaten?”

“My subordinate can eat anytime.”

The subordinate said, and led the way, pointing to the nearest workshop, opened the mouth and said: “Minister Li, this is a grinding workshop, there are small particles in the powder sent by the lime mine, and I need to grind it again, next to these It’s ground clay, and behind it is a small warehouse. All qualified powders are placed in the road. “

Li An walked in and glanced at it. The satisfied nodded, the grinding workshop is the first step in the production of cement, and it is also a very important step. If the grinding workshop cannot grind the material completely, the following production steps will not be very good Going on.

Therefore, the process of grinding is very important. Li An picked up the plastic gloves and gently put them on his right hand, and then slowly walked to the small warehouse of the opponent’s powder.

“You don’t have to follow it, this Official will do it alone.”

Li An is worried that too many people will cause excessive dust, opening the door to prevent the rest from entering the small warehouse.

“Yes, they are all powder-like, very good.”

Li An right hand grabbed a handful of lime powders at random, and kneaded it carefully. No hard particles were found, which shows that the grinding is very good and it is already qualified.

“Well, it’s very good here, it’s powder-like.”

After checking the lime powder, Li An went to check the clay powder again. In my heart, I was very satisfied. Both of these powders were well ground and were qualified products.

After taking off the rubber gloves, Li An was thrown in the workshop, and took a group of people out of the grinding workshop to visit the next workshop.

“Minister Li, here is the mixing plant, where all powders are mixed and mixed evenly.”

Subordinates introduced.

Mixing is also a very important step. To make the quality of the cement produced pass through, it must be fully mixed, and must be mixed evenly. Moreover, according to the scientific ratio, if the ratio is wrong, the production What comes out is scrap.

The mixing equipment is relatively simple. It is a cylindrical machine that each and everyone can rotate. After pouring all kinds of powder materials, it can be rotated and mixed, and it can be completely mixed together in about one hour.

The mixed materials are mainly clay powder and lime powder, and some other materials are added, but the quantity is not very large, and they are all materials that Anzhucheng can produce.

The raw material from the mixing plant is raw and cannot be used directly. The next step is the calcination plant, which is to put the mixed mixture into the calcining machine and use a high temperature of 1000 degrees. Calcination allows various mixed materials to react chemically at high temperature. In this way, even if most of the cement materials that can be used directly are manufactured, this product is called clinker.

Of course, the clinker is not finished yet. The next step is to mix the clinker with a small amount of gypsum and grind it again to make Portland cement.

Gypsum is a product produced with limestone as the raw material, and the lime mine is next to it. Therefore, the source of gypsum is not a problem. There is a small gypsum manufacturing workshop inside the cement workshop. There is no pressure to obtain a sufficient amount of gypsum. .

Li An and everyone walked to the last workshop, which is also a large grinding workshop. The mixture of clinker and gypsum calcined at high temperature will be the final step of grinding here.

“Minister Li, these are the cements just produced.”

He pointed to the gray cement powder and said.

Li An walked happily and pointed to the newly produced cement, opened the mouth and said: “Is it checked whether it can meet the requirements.”

The subordinate quickly pointed to a short wall outside the workshop, opened the mouth and said: “Minister Li, please see, the short wall outside is made of cement produced here, but it has not yet dried.”

Li An walked towards the short wall and kicked it a few times. It felt very good. The short wall did not move at all. However, the setting time of the cement is relatively long. The detailed technology of the cement cannot be determined until the cement is fully set. Indicators, however, based on Li An’s experience, the cement produced here is good enough to fully meet the needs of Anzhucheng construction.

“Yes, it’s good. We need to do more experiments to get out the detailed cement data.”

Li An spoke up.

To inspect the cement workshop is to take a look, not at all any new instructions, and then return to Anzhu City by car after reading.

Now, the cement workshop in the north of the city has been put into production, and the material reserves for building Anzhu City are more abundant. I believe that Anzhu City will be built faster.

“Minister Li, Anzhucheng officials dispatched by Imperial Court have arrived in Tocharian, and can reach Anzhucheng in up to ten days.”

A subordinate opened the mouth and said.

Li An nodded, opened the mouth and said: “putting it that way, we can only stay in Anzhu City for ten days, and we will leave after ten days.”

After spending so long in Anzhu City, witnessing Anzhu City change from a pirate den with nothing to a vibrant city, Li An has feelings for Anzhu City, a very deep feeling, both Feelings for things also have feelings for people. Among them, feelings for people are deeper.

It will be another ten days before leaving this city. Li An suddenly feels reluctant, and his heart is sour, especially those who are not able to let go of the two beautiful women, Bai Hu and Xiqi.

Li An was very happy at the thought of Bai Hu and Xiqi lying in their arms, Li An was very happy. If they just sent these two people back to Chunxianglou, and they would be tortured by different guests, Li An would be a little unhappy, but If you bring 2 people, Yoon-a and Ga-in should be unhappy. Moreover, there is still a long way to go in this way. I do n’t know how many red powder Ga-in will come across? With too many girls around, it is difficult to take care of them all, or you will be tired enough to choke.

In short, there is a contradiction in my heart, neither is it taken away, nor is it taken away, that tangle! Stuffed in my heart.

“Master, you went to the cement workshop to inspect today. You must be covered with ash. Would you like to wash it?”

Yoon-a asked gently.

Li An nodded, opened the mouth and said: “A bath is a must, but don’t need you to wait, let Bai Hu and Xiqi wait!”

“Why! Master, don’t we serve well enough.”

Yoon-a unhappy coquettish.

Li An touched Yoon-a’s little face, opened the mouth and said: “Yoon-a, it’s not that you are not good at serving, but we are about to leave Anzhu City, there will be at most ten days, we will leave Anzhu City is here. Bai Hu and Xiqi are going to stay. It’s been a few days. Master of course must accompany them more. “

“Oh, that’s it! This Slave understands.”

Yoon-a is also a reasonable and virtuous person, and she will not make trouble with Li An unreasonably. I heard that she is about to be separated from Bai Hu and Xiqi, and she feels a little reluctant. Although she is a little jealous of 2 people, not at all is so annoying .

Li An stood up and opened the mouth and said: “Yoon-a, you and Ga-in have a rest soon! Master is accompanied by Bai Hu and Xiqi.”

Yoon-a nodded, went outside and called Bai Hu and Xiqi, these two people are swinging in autumn 2, and they are not talking about it.

Looking at Bai Hu and Xiqi jumping up and down, Li An felt even more reluctant, and I really wanted to take them away!

“Go, let’s take a shower.”

Li An hugged Bai Hu and Xiqi and walked towards the dock by boat.

Although the fixed bathing baths in Anzhu City have been made very well now, Li An is still used to taking a bath on a boat. Where is more romantic and more private, can give people better enjoyment.

The hot water is prepared in advance for miscellaneous tasks. When Li An arrived on the boat, the hot water and cold water were already mixed, so take a short rest and take a bath in the bath.

Li An not at all how much lime powder was on her body, but the effect of the heart made Li An wash many times until it was confirmed that the lime powder on the body was completely cleaned, which came up from the big bath and wiped off the water on his body, Lie on the rocking chair and let Bai Hu and Xiqi massage themselves.

“Comfortable, really comfortable, press for a while.”

Li An enjoyed the request.

They are about to leave Anzhu City. Li An will naturally enjoy 2 more people for a while. After leaving, they will not be able to enjoy it.

“Minister Li, why not let Yoon-a elder sister and Ga-in elder sister come over and play together today?”

Bai Hu curiously asked.

When Yoon-a called her just now, because they sympathized with the two of them to stay and serve a large group of gracious guests, their words seemed to be quite caring and gentle, which made their impression of Yoon-a much improved.
