Bai Minghe didn't care about the exam, it doesn't mean that he is idle.

At this time, the white-named crane was in Shangyuan County, Nanjing.

Headed by the Ministry of Works, Shangyuan County and several surrounding county orders followed, and in front of them was a rocky mountain, and there was a fire burning at the mouth of a kiln, where lime was burning. There are about 20,000 people working here.

The white crane was biting a cigar and standing in the shed in a mink coat, his eyes closed, not knowing what he was thinking.

Four blue-eyed, golden-headed men were muttering over a stone slab.

"Is it so troublesome?" Fan Liang stood up beside Bai Minghe and yelled at a person who knew Chinese: "I said old Jinersen, don't you just want to calculate how hard this thing is?" Let me. ”

"You don't understand, it's science. Lord Bai understands! The middle-aged man named Jin Ersen said calmly to Fan Liang.

Bai Minghe still has his eyes closed, and he is anxious, but it doesn't mean that his face is also anxious. Roman cement is Roman cement, which is fired with feldspar and gypsum, and it is a kind of cement mixed with aluminum-vanadium earth, can this thing be used. Shira-nathan wanted a very positive answer.

Fan Liang pulled away Jin Ersen, raised his fist and punched the stone slab.

...... hiss, Fan Liang took a breath of cool air, this thing is almost the same as ordinary stone bars, and definitely harder than bricks. If the red brick himself made such a fist, it would be directly powdered.

Jin Ersen ignored Fan Liang and walked in front of Bai Minghe: "Lord Bai, it seems that this recipe can be improved." ”

Only then did Bai Minghe open his eyes and glanced at the county order of Shangyuan County.

"Lord Bai, don't worry. The workshop was built in 100 days, and from now on I will be able to eat and live here until it is built. Guarantee these ...... scientists. It is possible to make high-quality artificial stone. The lower officials understand that this is a weapon of the country. ”

"I'm tired." Bai Minghe hurriedly returned the salute.

After that, Bai Minghe turned to the Ministry of Works: "The Ministry of Industry also has to work harder, this thing will definitely be a weapon for repairing embankments and paving roads in the future." It's going to be hard, but it doesn't matter. All the talented craftsmen on the Ministry of Industry have been turned into officials, and the amount of money needed is not a problem. A problem that can be solved with silver is definitely not a problem. ”

"Don't worry, the old man has written down your sentence, and the problem that silver can solve is not a problem. This summer, with silver and this artificial stone, the Nanjing embankment was solved first, and there would be no problem. ”

Bai Minghe asked again, and Wang Cheng nodded.

There is no need to speak, Wang Cheng understands in his heart the formula and process of this thing. It's something that's strategically classified. It must not be spread to the outside world, and if other provinces want to build this kind of workshop, it is definitely under the supervision of the East Factory.

Before, who would have thought that after a pile of ash, plus sand and water. That is, seven or eight days, harder than a stone.

This is enough to prove that this item is extremely valuable.

The original ancient Roman cement was not easy to do in the Ming Dynasty. Because ancient Rome used volcanic ash for cement. Go to Daming to find volcanic ash, Daming has a volcano. But where is the kind of fire that breathes fire every day?

Scientists from the Byzantine Empire, their alchemists joined forces with the Dan Warlocks of the Ming Dynasty. Coupled with some knowledge that Bai Minghe knew, he summed up the formula of three kinds of cement.

The first is to use a large amount of slag produced by the blacksmith's workshop, but the amount of coal that the blacksmith can use, no matter how large the amount is, is not as large as the amount of cement used, so this scheme was placed after the test.

The second uses bricks, tiles, and porcelain ground into powder. It is also limited by raw materials.

According to the second method, kaolin is a good thing, but this thing is not allowed to be used, because it is the raw material of high-grade porcelain, and it is too wasteful to use it as cement.

The last type is feldspar. With bauxite as the main material, plus lime and gypsum. That is, the cement that is being tested at the moment, and the closer formula needs to be tested again, but now this one can be put into production and can be used.

Leaving from Shangyuan County, Bai Minghe took the skilled construction craftsmen of the Ministry of Industry to the island in the middle of Xuanwu Lake.

Xuanwu Lake began to be developed hundreds of years ago, and there are some ancient buildings. The best development is Liangzhou, which is the place where the prince of the Liang Dynasty studied, with beautiful scenery and various ancient buildings.

On Sakushu Island, the white crane pointed to the roundabout about 30 zhang wide and said, "Lean on the inner circle, and the dwarf trees on the shore should not be waist-high." Then draw a circle five zhang wide and transform it into a meadow, a hard grass. The outer ring of the meadow should have a tree wall and a tree one zhang wide, which is a racecourse. ”

The relevant personnel of the Nanjing Ministry of Industry immediately began to record.

"I don't need to record it, I've drawn a picture here, but I'm just going to talk about the details. The choice of tree species must be diverse, and it is also necessary to ensure that there is also green in winter. The outer ring of the island should run along the lake, close to the woods, and the road is one foot wide. The rest can be built into shops pù, all three floors. When choosing a tree species, you must pay attention to the fact that the tree must be taller than the building in the future. ”

Bai Minghe commanded, and an official asked: "Lord Bai, take a small road of ten zhang or a small road of twenty zhang." ”

"You can do this, and leave a public latrine, and you are not allowed to defile the island in the woods."

"Yes, yes!"

"Lingzhou, you don't have to worry about it in the early stage. 100,000 soldiers are already working, and they will build a stadium there, and the rest of the stadium will be protected from the original scenery, and there will be no need to build roads. At the junction with the roundabout, a door should be built, not in the door leaf, but in the door frame. ”

The people of the Ministry of Industry said, this is to build a memorial arch, this thing is not called a door frame.

But who would dare to open his mouth to disturb Bai Minghe's interest in talking.

"Liangzhou repairs the ancient with the ancient, and the antique is ancient. You are good at this, just build it well, there will be a banquet for distinguished guests in the future, but you can't let the envoys of those small states look down on our Ming Dynasty, pavilions, platforms, floors, pavilions must have the characteristics of the Ming Dynasty. "This request made by Bai Minghe is not a requirement for the people in the Ministry of Industry.

There are many craftsmen in the Nanjing Ministry of Industry, but they are at the level of repairing the imperial palace.

It's a little job, not a job.

"Finally, Sakurashu! There are four floors at the four corners here, each with four floors, and the total height should be more than five zhang. In the middle position, a ten-story building should be built, with a total height of more than ten zhang. The design drawings have been drawn, and you can revise the details. This building is to show the best things of cement, what is not really good in the eyes. ”

"My lord, ten zhang tall is not high, you can be taller!" An official from the Ministry of Industry said on the side.

Seeing that Bai Minghe didn't speak, the official continued: "According to legend, the tallest tower in the world is the pagoda of Yongning Temple in the Northern Wei Dynasty, with a total of nine floors and a height of forty-nine zhang. At that time, the zhang was different from the current Ming zhang, and there were about forty zhang after accounting. It's a pity that it was destroyed by the fire. The existing is the Shanxi Yingxian pagoda built successfully in the sixth year of Jin Mingchang, 21 zhang high! ”

"How many years have you been repairing?" Bai Minghe asked.

"About seven years, 40,000 feet of red pine wood was consumed."

"This, it will take three months to build, but your construction is very interesting, this is a lake, and the foundation is inevitably not as stable as on land. In this way, after building this building, you also have experience in using cement, and then you will build another floor in Nanjing. It's just that the official thinks that the wood is always a little flexible, and the cement is as hard as a stone, and it is just broken. In the unlikely event of an earthquake or something, it will always be affected, so this aspect should be considered more. ”

What Shirana Crane said is reasonable, things that are too hard are afraid of earthquakes.

But it's not like there's no way around it.

"So, take your time. Familiarizing yourself with the performance before giving full play to its strengths is what you are best at. First build a ten-story building, with a base of one zhang, and then two layers of the base. This is already three zhang, and then up is a seven-story brick and concrete structure, by the way, add some design, old legs and feet are inconvenient, how to go upstairs? You can think about these details, and you can start in a few days. ”

After talking about the design of the five islands of Xuanwu Lake, Bai Minghe didn't say a word, what will these be used for in the future.

On the side of Xuanwu Lake, in fact, it has already begun to move, and the foundations of several main buildings have been dug up, and the construction will start just waiting for the cement to be used. Prefabricated floor slabs have also begun in Shangyuan County, which is the first brick and concrete structure building in Daming, and Bai Minghe is looking forward to it.

I believe that it will take three months to cover the main body, and then two months to decorate, and it will definitely be usable in half a year.

It's definitely a good time to put it after the summer harvest.

Bai Minghe didn't tell anyone what he spent his energy building for, but it was impossible to hide the people of Nanjing City from the Xuanwu Lake construction, and a large number of recruitment information had been posted to the four provinces in the south of the Yangtze River, but anyone who had idle labor at home could come to Nanjing to find a job.

Whether it is the large amount of labor required by the white crane, or the many new workshops in Jiangnan, there is a large demand for manpower.

Drifting Snow Building!

Wan Xue'er had a few job postings on her desk, and others didn't know what Bai Minghe was going to do, but she did.

Wan Xueer clearly remembered that Bai Minghe told herself that she would build a building in Xuanwu Lake for herself, which is the real top entertainment city in Nanjing, Super Casino.

There is pressure, not just a little pressure, but a huge pressure. Wan Xue'er thought about how she would face Qinghe and the two ladies of the white crane after this building was built. Bai Minghe is a little too much this time, unless he builds this for other purposes, otherwise let people say that it is for himself, and he is afraid that he will not be able to live.

On this day, after Bai Minghe returned home, he received a secret decree from the Ming Emperor.

The secret decree is very clear, find a companion for a prince to read, fortunately, Zhu Jianshen is only six years old in one year, and this year the Ming Emperor will personally choose a suitable companion to read. This will is just such a sentence, but it is an extraordinary sentence. Bai Minghe felt in his heart that there must be a story in this.

I'm afraid that there is a story, and I can't discuss it with someone, and if I doubt it, it's disloyalty and stepping on the red line.

On this day, a baby's cry came from a house in the east of the imperial palace in the capital, and the people who came to congratulate formed a long line, that is, the queen went to Baifu to congratulate in person. Emperor Zhu Qiyu of the Ming Dynasty only asked one sentence in the palace: "Male?" Woman? (To be continued......)
