The discovery of Yangshugou karst cave has solved the problem of raw materials that plagued the Hongxing camp, but how to transport the ore from Yangshugou has become a new problem.

Yangshugou is in the deep mountains, there are dozens of miles of mountain roads out of the mountain, not to mention sent to the Red Star Camp, in the absence of cement roads, trains, every time the ore is transported out of the mountain, it can only be carried on the back of people, even if the labor cost is not considered, such a transportation volume is also outrageously low.

"There are nearly 100 miles of mountain roads along this road, and there are almost 60 miles of mountain roads, and it is not easy to build a mountain road that can walk with ox carts."

The four elders of Damatsu Village gathered in the conference room, looking at the simple map, the mine was found, and it would be a great loss if it could not be transported out because of the inconvenient transportation.

The so-called mountain roads in later generations have roads, even if they are not cement roads, they are loess roads, and the so-called mountain roads in this era are mostly animal roads, that is, because the wild roads formed by wild beasts after long-term migration back and forth, and some places even have to crawl with hands and feet, which is why most of the army can only sigh in the face of such mountain roads.

"Can it be smelted on the spot? Directly transport the iron ingots out? Lu An looked at Yue Liang and asked.

Yue Liang nodded and said, "I went there, there is indeed vacant land to build a furnace, but we don't just want to make iron, but also the glass and soda ash that Ma Lang said, if they are all fired in Yangshugou, then it is still a problem for so many goods to be shipped out, the mountain road is rugged, and the glass is something I remember Ma Lang said that it can't withstand the toss." ”

"Still have to build roads!" Ma Qiang pointed to the road on the map and said, "Even if he has a hundred miles, he has to build a two-lane road, but there is no coal in Yangshangou, do we still need to transport coal into it?" ”

"The road of a hundred miles, even if you only build the mountain road, it will cost tens of millions..."Yang Wanli gritted his teeth and said, "Late repair is not as good as early repair, isn't that group of people in Niuhoi Ridge also building their own road, let's repair it!" ”

The people in charge of the money have said such cruel things, and the others naturally have no opinion, and it just so happens that the construction of various workshops has come to an end, and these manpower can be transferred to build roads.

Road construction must be reported at any time, Changping County Commander heard that the Red Star Battalion is ready to build a two-lane road by itself, this is a political achievement, naturally there is no opposition at all, as long as it does not affect the cultivated land, and even patted his chest and said that if someone obstructs the road construction, the county government will help to deal with it.

Two lanes are two carriages side by side, which is also interesting, the road width standard of the Han Dynasty is almost different from that of later generations, the Han Dynasty and the Qin system, the width of the track is six feet, A total of 138.6 centimeters in later generations, and the track in later generations was influenced by the West, which was a British and American track system, 4.85 feet, a total of 143.5 centimeters, only five centimeters apart, because both the Qin and Han tracks and the Western Roman tracks were determined according to the horse's buttocks, and the western horses were slightly larger than the eastern horses, and the buttocks were larger, so they were wider, but they were also limited.

The horse never dreamed that the width of his ass could have such an impact...

Now that we have decided to build a road, the next question is what road to build.

Just like there are highways and loess roads in later generations, the ancient roads are also graded, and the highest level is naturally the Chi Road that Qin Shi Huang built and maintained continuously, the Chi Road is very wide, and the width of the plain area can reach nearly 70 meters, the purpose of such a road is to quickly run the army in the event of a war, and it is the main way to connect the counties.

The second is the county road, which is the road connecting the counties, which is not as particular as the Chi Road, but it is also a big road, in addition to the rugged and difficult roads in the southwest and other places that cannot be built too wide, the general width should also be more than three cars in parallel, and the road between towns and towns is often two cars, one car is the lowest village road, as for the car can not walk, it is called the path in ancient times.

But no matter what kind of road, the basic material is cooked soil, that is, the soil is fried, and then compacted, this is done to ensure that the road will not grow weeds or insects, if it is not easy to understand, you can think of the kang in the north, such a road is extremely solid, but it is also time-consuming and laborious.

As for Ma Qiang, he is going to build a cement road.

First, this road is ready to be used to transport ore, and the carrying capacity is not small, so prepare a team to build the road at any time, and secondly, cement manufacturing is extremely important for both military and water conservancy construction in the future, and it is time to get started.

Many people think that the lack of cement in ancient China is a manifestation of backwardness in the West, but this is actually the same as the truth that there is no porcelain in the West, or the problem of raw materials, the main raw material of the original cement used in ancient Rome is volcanic ash, and there is really no ...

A large amount of limestone was found in the mine cave of Yangshugou, this limestone is actually one of the most important raw materials for making cement, and the other two main materials are sand and iron, sand is silica to put it bluntly, quartz stone raised his hand to say that I can too, and iron...

What do you think the road is for?

The temperature required to fire cement is 1,600 degrees, which is not difficult for the Red Star Battalion, so Ma Qiang prepared to take hundreds of people into the mountains first, surveying the terrain and building cement furnaces and mills.

As for why the mill is used, it is because burning cement requires grinding various materials into powder and then mixing them together for calcination.

Therefore, the pollution of cement is very serious, and it is easy to get bronchial or lung diseases if you are engaged in cement work for a long time.

In order to minimize the lung problems of the workers, Ma Qiang also took thousands of masks that had been prepared and not used up.

Along the way, surveying suitable places to build roads, and looking for water flows, Ma Qiang not only needed to build a road, he also needed to build a concentrator here.

It is also infuriating, China's iron ore is very much, but the quality is simply sad to listen to, smell and cry, the average grade of iron ore in the world is more than 40, but China is only more than 30, and it can be basically determined that the reason why the world average is more than 40 is because the quality of China is too poor to pull down.

If you want to compare, for example, Australia's iron ore, more than 60 abound, you know, because iron ore is a compound, not pure iron, the highest theoretical grade is only about 70, so don't blame the Chinese ironworks in later generations to import foreign iron ore, do not buy domestic, domestic ore needs to be selected before it can be used, and foreign ones are really thrown directly into it to burn.

Although Ma Qiang can't tell the exact grade of the iron ore in Yangshugou, he knows that it can't be high, so he must build a concentrator, which needs water.

In addition, Ma Qiang also plans to build a hydroelectric power station here, manual beneficiation is too troublesome, and it is much more convenient to use electromagnets to beneficiate.

Ma Qiang is very confident that the Yangshugou mine must be the most advanced mine in Asia in this era, no, the world! Not one of them!

Well, he doesn't blush at all...
