With coal, then everything is solved, and under Chen Chen's instructions, people are also working quickly.

Choosing a relatively strong mountain, he ordered people to start digging caves.

"Lord Wang, can the soil dug out of this cave be used to make bricks?" The people in the Ministry of Engineering looked at the excavated soil and thought that they could make bricks.

Chen Chen shook his head, looked at his notebook and read: "The soil used for burning bricks is commonly known as clay, which should have good plasticity, this kind of soil was formed about 80,000 to 120,000 years ago, when the earth's climate was warm and humid, and the rich biological action made the soil formed during this period soft and sticky, and we want this kind of soil." ”

The officials next to him all looked at Chen Chen in confusion: "Lord Wang, this plastic and biological one, what does this mean!" ”

"Well, this, you don't understand it, you are responsible for digging the soil, and the king will judge when the time comes." After saying these words, Chen Chen couldn't wait to give himself a big mouth, and he leaked his mouth again.

Shimin dug quickly, Chen Chen carefully identified the essence of the soil, and after digging for a long time, Chen Chen pointed to a pile of soil in surprise and said excitedly: "Yes, yes, yes, that's it, that's it." ”

Chen Chen touched the clay and felt the characteristics of the clay, which is a clay soil with few sand grains, and it is not easy for water to pass through it to have good plasticity.

The people from the Ministry of Industry hurriedly stepped forward to memorize the characteristics of this kind of soil, and then asked the people to dig up such soil.

"By the way, let's pay attention when digging, don't dig up the mountain." Although these mountains are anticlinal mountains that Chen Chen found after precise testing.

In modern construction, most of the tunnels are also chosen anticline mountains, because in the anticline, the force direction of the rock layer is tension, and the rock hardness is low, so the tunnel is less stressed, the probability of collapse is relatively small, and the construction is easier.

Chen Chen planned to order someone to get these diagrams out and make a tunnel into the mountain. In this way, not only the soil for burning bricks is solved, but the tunnels dug can also be developed into tourism at that time. If all the mountains were to be tunneled and then connected by roads, not only could mountain tourism be developed, but also some secret weapons could be hidden in them, which seems like a good idea.

Soon the clay was dug up, and then the pure soil was refined according to the method. Then add water to the pure soil and moisturize, and repeat and refine like noodles. Hundreds of cows were driven in to tread the mud and make it into thick mud.

"Well, this cow seems to be a farmer's cow, right? You didn't take it by force, did you? Looking at these cows, Chen Chen couldn't help but wonder for a while, this is simply the farmer's cow.

Before the words fell, several peasants had already broken through the encirclement and ran in and knelt down in front of Chen Chen: "Lord Wang, my cattle were forcibly pulled away by officers and soldiers, please be the master of the matter, there are only these cows in the house, ......", crying a lot.

"Is this money enough?" Chen Chen hurriedly took out a few pieces of silver from his sleeve and handed them to the farmers, the crops were pitiful, so he naturally had to make compensation.

When a few people saw it, they hurriedly grabbed it in their hands, but they didn't stop crying in their mouths: "We have raised these cows for a long time, and my daughter-in-law and child fed this cow a lot of forage, and the child fell ......ill in order to cut the cow grass a few years ago" Several people also pressed their heads heavily on the ground, and blood appeared on their foreheads......

"Why, isn't five taels of silver for a cow?" Seeing these people continue to cry and shout, Chen Chen's psychology also became a little angry.

"Someone, send it for the king." Although he was angry at the soldiers' forcible seizure, looking at the scheming and greedy of these peasants, Chen Chen's heart suddenly felt bad.

Before Chen Chen's words fell, a soldier immediately stepped forward and dragged his neck down.

"Lord Wang." Several soldiers looked at Chen Chen tremblingly, it seemed that they were soldiers who forcibly seized the peasants' cattle.

Chen Chen waved his hand and snorted coldly: "Drag it down, fifty big sticks, give them Zhang Zhang memory, and they are not allowed to take it by force in the future." ”

Several soldiers knelt down and kowtowed.

After dealing with this matter, back to the construction site, the clay was almost there. Chen Chen ordered people to mold the clay through the billet molding.

"Remember, when shaping, the soil should be compacted, and the place where the bricks are placed should be covered with fine sand to prevent the soil from sticking. The bricks should be dried in the shade, and should not be exposed to the sun to cause cracks and deformations in the bricks. Chen Chen instructed back and forth on the construction site, and all the officials of the Ministry of Industry followed closely behind to study.

Seeing that all work links were carried out in an orderly manner, Chen Chen was also relieved, and turned back to the people in the Ministry of Industry and said: "The next link is more important, you should remember it well." ”

"After the bricks are completely dry, you can go into the kiln to fire, which is the most important part, and if you fire, you will use the coal mine that has just been dug out to fire, and you must not cut down trees to fire.

"After more than ten days of firing, the green body will be sintered, and then sealed and fired until the bricks are cooled, understand?"

Everyone in the Ministry of Engineering wrote it down one by one.

After looking at the progress of the project, it was a matter of time before the bricks were unearthed, so I took people to another construction site.

Since the work of the brick factory is almost the same, the cement plant also needs to be built as soon as possible, after all, it is not possible to have bricks without cement.

"Lord Wang, at this moment, according to your orders, we have mined stones, and we have also found coal mines here on the side of the brick factory." An official saw Chen Chen coming over and hurriedly greeted him.

Looking at the facilities of the cement factory, Chen Chen was extremely satisfied, there should be everything, of course, compared with the brick factory, the cement factory that made cement in ancient times was slightly easier.

"Come on, first burn the stones into lime, and then grind the lime into powder. The clay should also be fried first, dried, and sieved out of the clay powder for later use. He turned around and gave an order to the people in the Ministry of Industry, and someone in the Ministry of Industry immediately organized migrant workers to start production.

Chen Chen watched everything going on, then turned back to the people in the Ministry of Industry and began to instruct, teaching methods:

"Grind the coal mine into powder. Then 70% lime powder, 20% clay fine powder and 10% anthracite powder are stirred evenly and milled again. When grinding, you can add a little water to reduce dust, and the lime, clay, and anthracite mixture that is milled into powder is cement raw meal. ”

"After that, the raw meal is poured into the mixing turntable, and the mixing turntable should sprinkle water on the cement raw meal in the tray when it rotates, and when the cement raw meal forms a pea-sized ball in the mixing turntable, it can be put into the lime kiln to fire cement clinker."

"When the lime kiln is ignited, the coarse firewood is put on the inside of the kiln, and the firewood can be added little by little after the firewood is burned, and there is no need to add additional coal. When firing clinker, it is necessary to discharge the fired clinker from the bottom of the kiln and feed the material from the kiln mouth for continuous firing. When firing clinker, you can only burn a dark fire, not an open flame, and you must keep poking the kiln with a long stick from the mouth of the kiln, otherwise it will cause a kiln accident, which will kill people. Wait for the clinker to cool and add 5% cinder into it, so that the finished product comes out, remember? ”

The people in the Ministry of Industry showed a look of hesitation on their faces and shook their heads slightly.

"It's okay, take your time." Chen Chen comforted for a while, and carefully instructed this person.

"Lord Wang, the lower officials understand." After being instructed, the officials took the various methods to heart.

"What's your name, you're doing well, from today on, you're the person in charge here, and you'll be suspended from the imperial court in the future." Looking at the appearance of this person's sixth grade, Chen Chen thought about it slightly, and immediately promoted this person from the sixth grade to the third grade.

"Xiaguan Sun Sheng, thank you for your love." When this person heard this, he couldn't help but be overjoyed, and hurriedly knelt down and kowtowed to thank him.

Chen Chen nodded slightly, helped him up and said: "The brick factory is not far from the cement factory, from today on, you are the general person in charge of these two factories, the core technology of these two factories is not allowed to leak, and you have to find a way to be optimistic about the workers here, understand?" ”

For the ancient officials, some important projects were royal secrets, and it is believed that these officials also knew how to ensure the secrets here.

When Sun Sheng heard this, he nodded again and again: "Although the prince can rest assured, the minister has his own opinions in his heart, and he will definitely ensure the safety here." ”

"Well, this king is very optimistic about you, don't let this king down, or ......"

"Yes, don't worry." Sun Sheng nodded tremblingly, looking like he had everything under control.

Chen Chen looked back and forth, then he also put his mind at ease, and ordered the soldiers to guard this place well, and idle people were not allowed to approach.

When the soldiers heard that they were guarding such an important place, they naturally attached great importance to it.

After making sure that everything was in order, Chen Chen returned to the capital with peace of mind, all he had to do was to sit and wait for the product to come out, and at the same time to rectify the problems of these laborers.
