The Turks are actually relatively idle all year round, because their main job is grazing, and this year, after each of these Turks transplanted alfalfa grass in their own land, they don't have to worry about this year's pasture, their work is much simpler!

Grazing, on the other hand, can be handed over by several families to one person to graze, or even a village of cattle and sheep to several people to graze, and the rest can come out to work.

At present, there are about 100,000 Turkic people, and the population gathered near the Huozhi River has exceeded 70,000.

As the Anno began to recruit workers, and heard of working for their chief, countless Turks began to gather here, leaving their homes with their own women, old people, and half-grown children, and almost all of them rushed here.

From 15 to 40 years old, about 30,000 Turkic men gathered.

Anno and the others quickly distributed these Turkic people, and it was impossible for them all to work in the industrial city, the current industrial city could not accommodate so many people, and the number of people that the entire industrial city could currently accommodate was only about 3,000 people.

However, since the rest of the people came, Huo Gang simply did not let them go back, but after thinking carefully, he directly began to build the road.

Because with the successful construction of the blast furnace and open hearth furnace in the industrial city, the population of the industrial city is increasing, and the road load between the industrial city and Yangguan and Yumen Pass will inevitably become larger and larger.

The main road construction is to build the road between the industrial city and Yangguan, and Yangguan to Yumen Pass, and the road construction on the Gobi Desert is actually relatively simple, mainly because the ground on the Gobi Desert itself is relatively flat and hard.

Although the wind can blow yellow sand here, the roadbed is very hard under a few centimeters of yellow sand.

For this era, such roads were actually sufficient, but these roadbeds began to be tamped to a certain extent, first using rice ropes to straighten the roads detected in advance, then using a limited shovel to shovel away a few centimeters of floating soil above, and then using flat stones that could be lifted by three people to tamp the road below.

After the whole road surface is tamped, it is actually very hard, and there is no problem at all in using it as a roadbed, especially the roadbed of this era.

The road is designed to be 4 meters wide, about 110 kilometers long, and 15 centimeters thick.

As for the formula of concrete, Huo Gang didn't know whether it was applicable or not, anyway, he remembered a formula, which was about 0.47:1:1.59:3.39. This ratio is the ratio of water, cement, sand and gravel.

The reason why Huo Gang knows this is because when Huo Gang built the road in his hometown in his previous life, he seemed to use this ratio, and he didn't know whether he was qualified or not, anyway, when he chatted with that little brother, he remembered it.

Regardless of whether it is qualified or not, it will definitely be enough in this era.

This ratio is roughly the proportion of these components in a cubic concrete, that is, 175 kilograms of water, 372 kilograms of cement, 593 kilograms of sand, and 1260 kilograms of gravel. After Huo Gang gave the approximate proportions to Wang Luo, he didn't care about the rest.

However, there is one point, it stands to reason that the concrete road is easy to damage because of the edge part, so the reinforced concrete structure should be added to the edge part, but Huo Gang has no steel bar now, let alone steel bars, and there are no iron bars, so he will not add them first.

And the four-meter-wide road may be expanded in the future, so I will use it when it is expanded in the future. The four-meter-wide road, if it is two tall cars, is enough to meet back and forth, and it is more than enough, so for the time being, they will not add reinforced concrete structures to the edge of the road.

It is impossible to pour concrete directly on the rammed pavement, there is also a cushion on it, which is composed of slag mixed with gravel, etc., and the cushion is also about 15 centimeters thick, and the slag required for the cushion does not matter, because as long as they start to make iron, the amount of these slag is huge.

On the cement side, they have already tested it, and it is possible to replace slag with ground iron ore, and there is almost no difference in terms of structural strength, etc.

With a four-meter-wide and 15-centimeter-thick pavement, an average cubic concrete can be poured about 1.6 meters long, and a 110-kilometer-long road requires about 26,000 tons of cement, and now the cellar furnace of the entire industrial city can fire about 10 tons of cement once fired, and it can be fired about 7 times a day, that is, 70 tons of cement can be produced every day.

At this rate, Huo Gang would need to produce cement for one year to build it completely.

Of course, the output of cement will definitely increase, the first thing that restricts cement production is that there are too few workers, which can be solved immediately, and the second is that the new cellar furnace is still being built, but it has not yet been put into use.

The third is that the amount of slag cannot keep up with the firing of cement, but this is simple, just increase the mining of iron ore and other aspects. There is no slag to use iron ore directly, although there is some luxury, but for Huo Gang, this waste is worth it.

The last point is that the grinding speed is relatively slow, but this can be solved quickly, because with enough manpower, more large windmills have begun to be built on the Lumu side.

The abundant wind resources here allow these large tower windmills to run almost 24 hours a day, but there are no lights at night in this era, otherwise, Huo Gang can directly implement the double shift system.

However, according to the plan given by Sun Er, in about a month, they can expand the cement production capacity by 5-7 times, and as for the follow-up, it depends on the mining situation of iron ore.

Otherwise, 5-7 times is basically the limit, which is also Huo Gang's hands have enough manpower to use, but his manpower is still too small, if there are another 200,000 people, Huo Gang can mine new limestone mines near the iron mine.

On the iron ore side, Huo Gang has already discovered a new limestone mine nearby, although the number is not as large as here, but it is no problem to accommodate at least a few hundred people to mine.

With the construction of the road, there is no shortage of cement Huo Gang for the time being, after all, these cements have been continuously fired for more than two months, although the output is certainly not so much at the beginning, but just to reach 10 tons of output each time, it has almost been maintained for a month.

Therefore, the reserves of cement are now close to more than 2,000 tons, and from the reserves of cement, it can be estimated how many materials Longxi Li has transported to Huo Gang and them during this time.

One ton of cement can pave more than 4 meters of road, and more than 2,000 tons, almost more than 8 kilometers of concrete road.

However, the paving of concrete roads is not so simple, for example, every 5-6 meters or so to reserve an expansion joint to avoid cracks caused by thermal expansion and cold contraction of concrete, the bottom of the gap is stuffed with wooden strips, and the upper part is stuffed with slag and other fillers.

For example, after the concrete is poured, it needs to be watered for maintenance, and this time should last at least 7 days.

Huo Gang told Wang Luo everything he could know anyway, and the rest of the construction process was controlled by them on the spot.

With the development of the road repair project, the entire Yangguan vicinity instantly became a hot construction site, looking at such a scene, Huo Gang was a little excited, such a scene, Huo Gang had seen it when he was a child in his last life.

And in this era, only some large-scale projects in China can have so many people.

But those projects are completely different from what Huo Gang is doing in front of him! For example, the former Sui Dynasty dug the Beijing-Hangzhou Grand Canal, all of which were in conscription, and the people who came to work did not have any salary, not to mention that they could not even have enough to eat.

They can't even eat enough, these people are naturally depressed every day, but the scene in front of them is different, everyone is almost throwing off their arms to work, because they not only eat better and eat more every day than at home, but more importantly, they still have a salary every day.

The food they receive every day alone is enough for all members of their family to eat for a whole day, so that the food in their family can be saved. For ordinary people in this era, a little bit of food is a matter of care.

Anyway, they are idle, if they are at home, they can't create much value every day, and they also need to consume their own food, which is more important, these people are very clear.

What's more, they are working for their leader, and everyone is working to the best of their ability, so to speak.

Anno and the others also showed a lot of women, but they did not work, but cooked, after all, there were more than 20,000 people, and the number of people needed for cooking alone was not a small number.

Of course, the cooks can also take care of the food, but there is no salary to receive for the time being, but even so, the women who signed up almost broke the registration point.

If it weren't for Anno's people saying that there would be more actions for them women to do, it is estimated that many women would be able to fight on the spot, and these Turkic women are very strong.

For them, although they are only cooking, they are not paid, but it is also important, after all, because they have one more person to work, it means that there is one less person in the family to eat, and they can save more food at home, so that they do not have to go hungry in winter.

Huo Gang is naturally not afraid of taking care of the rice, because for Huo Gang, he doesn't care if he has money or food in his hands, these people come to Huo Gang to eat, their own food is saved, and for Huo Gang, the food is still in the entire Han Dynasty.

As long as ordinary people have food in their hands, their entire Han will be very stable.
