Qinjiazhuang, under the slope of the mountain.

Qin Huaidao thought while directing everyone to dig the kiln.

Lime firing is simple, only limestone, marl and other calcium carbonate-containing rocks are calcined in a lime kiln to 1,200 degrees, and then cooled and discharged out of the kiln, which is quicklime.

Cement is a lot of trouble, Qin Huaidao vaguely remembers that the main material is limestone, clay, iron ore and cinder are ground in a certain proportion and calcined into mature material, the question is how much is this ratio? After the clinker is made, it has to be mixed with gypsum and lime to stir evenly in proportion, and the cement is mixed and finely ground to be smooth, what is this ratio?

Qin Huaidao is a little uncertain, he can only estimate it, it is easy to burn, some are coke and coal, but before burning, the raw materials need to be ground fine, such as limestone, how to grind a large piece after being transported?

Do you smash it manually? It's too slow!

"No, we have to get a waterwheel." Qin Huaidao pondered.

The waterwheel rotates by hydraulic power, can become a power source, with the help of rotary torque braking, connect a large stone mill to rotate, you can mix clinker and gypsum into it, grind it into cement, but you can do more stone grinding, the pores of the upper and lower joints are larger, so that everyone can smash the big stone into a small stone, and then put it in and grind it finer.

The question arises - where to find such a large stone mill? Do it yourself?

Qin Huaidao felt a little big, it was all about it.

Fortunately, there is no shortage of manpower in Qinjiazhuang, during this period of time, all the bodies are strong, and some are strong, Qin Huaidao explained, and after seeing that the problem was not big, he pulled Huang Lao to the river outside Zhuangzi.

The upstream is not intercepted again, the river is leisurely, it has to be more than one meter deep, four or five meters wide, the water flow is enough, but the impulse is not enough, it needs to be intercepted into a weir, the opening is concentrated to shoot, the flood discharge effect is formed, the speed and impulse of the water flow are increased, and the waterwheel rotates to be powerful.

Qin Huaidao didn't explain much, and walked downstream with Huang Laoshun River for a distance, and saw a bend in front of him, where the water was concentrated, the water surface increased, and then formed a slope more than one meter high, the height was not big, but it was also rare.

"Huang Lao, is there a waterfall in front of the river?" Qin Huaidao asked.

"No, there is only one terrain difference in the young master's fiefdom."

"So be it, I need some strong labor." Qin Huaidao looked at the surrounding terrain and plains, it is indeed not easy to find a river with a large drop, a drop of one meter, if you build a two-meter dam to stop the water, it will fall down to three meters, which is barely enough.

What's more, in their own fiefdom, not far from Zhuangzi, it is much more convenient to build a road to enter, and other people's fiefdoms may not be used to build dams and hold back water for themselves, too far, transportation is also a problem.

Huang Lao couldn't help but ask curiously, "What is the young master here for?" ”

"Build a dam to store water, and then make a waterwheel, install a stone mill, it will be of great use in the future, and it will be convenient for everyone to grind noodles in the future, all the trees on the other side of the river will be cut down, and a mill will be built, and the small one will be used for everyone to bake the fire at night, and the terrain will be leveled, and it will take fifty strong laborers, and the wage will be thirty wen per day."

"It doesn't matter so much, as long as the stone mill is used by everyone in the future, and you are willing to do it without money, is the waterwheel the kind of watering that is used? I've seen it when I fought with the old general before, but no one in our village will do it. Huang Lao reminded.

"Do as I say, find a few people who can do some carpentry work with me."

"The young master can make a waterwheel?" Huang Lao asked in surprise.

"I've seen it before, I'll know some." Qin Huaidao said perfunctorily, I have indeed seen it, I still know the general principle and appearance, it doesn't matter if I haven't done it, just try it more, look at the sky, and added: "Start construction tomorrow, say hello to the people downstream before starting construction, so as not to misunderstand, just say that the water is stored to make a water mill car, and in the future, they can come to the village for free to grind wheat, but we have to use it when we don't use it." ”

"Okay, the downstream old man went to say hello in person, it's not a big problem, grinding wheat is the most labor-intensive, and it's free, they can't wait for it, and they don't stop the water and don't give it to them." Huang Lao agreed.

Huang Lao went directly downstream, Qin Huaidao wrote down the terrain, returned to the ancestral hall, saw that He'er was still sorting out the account book, encountered a few problems that were not very clear and didn't know how to record, Qin Huaidao explained one by one, then asked for some paper, picked up firewood and charcoal to draw a map.

One is the construction drawing, how high and wide the dam is built, what style of the waterwheel, how high and how big, and the room next to it needs to be built, how big the room is, how to walk the road, and where to put the broken stones in the future, all of which need to be designed to avoid making mistakes and reworking, which will be troublesome.

Considering the long-term use, it is better to use stone and cement for the dam to be built.

Thinking of cement Qin Huaidao has a headache, there is no waterwheel grinding, this cement is not easy to do, without cement, this dam is not strong, it can't be made into a waterwheel, and things fall into a dead loop.

After pondering for a while, Qin Huaidao decided to do it synchronously, the waterwheel can first level the ground, the road surface, and then build the mill, and at the same time experiment with burning cement, the amount is not large, the problem of artificial smashing and grinding is not big, burn out the cement and then build a dam to make a waterwheel, perfect.

Not long after, the drawings were drawn, Qin Huaidao took them in his arms, and continued to tutor He'er to do the accounts.

Seeing that it was about to be dinner, Jia Youcai hurriedly came back, took out a copy of the title deed and said excitedly: "Young master, the hillside has been bought, the price of this barren mountain that no one wants is not high, about fifteen acres, a total of three hundred taels of silver." ”

"Great." Qin Huaidao took the title deed in surprise and looked at it, and after confirming that it was correct, he continued: "Uncle Jia, a large number of people are needed to transport the stones over, but the road over there is narrow, and you can't take a carriage, you can only take a wheelbarrow, but what can you do?" Qin Huaidao asked with some expectation.

"Young master, you took this mountain for the stones?" Jia Youcai asked in surprise, seeing Qin Huaidao nodded, he estimated that this stone was of great use, the young master's recent methods were incredible, he didn't dare to ask more, and said contemplatively: "Everyone in the village is busy making mud cylinders......

"Forget about the Zhuang people, find another way." Qin Huaidao interrupted, he was going to make honeycomb coal soon, this is a massive number, and the people in the village can't be busy at all, so they can't be transferred anymore.

Jia Youcai thought for a while and said: "It's winter now, and there's nothing to do at home, you can find a tenant in the nearby Zhuangzi, ten centiworkers a day, don't worry about food, everyone must be willing to do it, idle is idle, how much does the young master need?" I'll talk to them. ”

"The more the better, you need to transport all the stones of that mountain, don't count them manually, a big cart full of fifty wen, let's not care if they are a family at the same time, or a person, or from somewhere to transport stones, but the tools are brought by themselves, if there are no tools, you can lend them money to buy them first, and in the future, they will cherish it, not waste, as long as it is transported to the designated place in Qinjiazhuang, the money will be given, but as long as the prescribed stones, not all of them will be wanted." Qin Huaidao advised, settle by day, and after a long time, you will cheat and play tricks, and you will be reduced to eating a big pot of rice, which is not advisable.

"This is a way, regardless of the process, just look at the results, good counting, but also mobilize enthusiasm, the family goes into battle faster, and the tools come with to avoid waste, isn't fifty a bit much? The work went smoothly, and two large trucks could be transported in a day, which was 100 Wen, and there was no such treatment within a radius of hundreds of miles. ”

"It's okay, just do it, hard work, big consumption, give more money so that everyone can eat enough and work hard."

"The young master is benevolent and righteous, and the old man will contact him." Jia Youcai sighed and hurried away.

At this time, a guard hurriedly came over and said, "Young master, the princess is here." ”

Qinjiazhuang has been sealed, and no one dares to let the princess in easily, so she has to report it first.

Qin Huaidao was a little surprised: "Which princess?" ”

"The other party calls herself Princess Yuzhang."

"Bring it here."

Qin Huaidao couldn't understand what Yu Zhang was doing here, it couldn't be that Jinyang had an accident again, right? There's no reason, there are no side effects after drinking Luo Han Guo.
