Chapter 849 A complete prodigal! How do you think I save my manpower and time?
Under the force of Ying Chengyu, Ying Zheng followed Ying Chengyu downstream along the river bank with a calm expression but a smile in his eyes.
Not long after, another wave of heat hit his face. Ying Chengyu breathed a sigh of relief and said cheerfully: "We're here!"
Looking at the blast furnace standing in front of him, Han Cang puzzled and asked: "Isn't it necessary to use iron materials to build that road?"
Ying Chengyu shook his head: "Iron is of no use. When the art of steel-making is perfected, I will use it." Rebar was also put into the road. ”
"The blast furnace in front of you is not used for iron smelting, but for firing materials needed for road construction."
The monarchs and ministers of the Qin Dynasty secretly smacked their lips after hearing what Ying Chengyu said.
That’s steel!
If anyone's family can get a steel sword, it can be regarded as a family heirloom, and it can help generations of people charge and kill the enemy and win military merit.
In the end, you actually wanted to bury the steel in the road?
spendthrift!
A complete prodigal son!
As for Ying Chengyu’s second sentence, the monarchs and ministers of Great Qin were completely confused.
Ying Zheng couldn't help but ask: "The materials required by Brother Wang to build Changlan Avenue actually need to be calcined in a blast furnace?!"
Ying Cheng nodded and said: "What the elder brother said is true. .”
Ying Zheng: ...
Brother Wang, can’t you tell that Brother Nai is questioning you rather than questioning you? !
Pointing to the river bank, Ying Chengyu introduced: "The various materials that have just been ground into fine powder will be transported here by water."
"After unloading the ship, the craftsmen will remove the slag powder. All the other powders are mixed evenly in proportion, and then put into the furnace to be calcined at high temperature. After forming clinker, it flows out from the mouth. "
Following Ying Chengyu's gesture, Ying Zheng saw the blast furnace. The lower hole that was supposed to flow out of molten iron has been opened up much larger, and what flows out of it is no longer molten iron, but molten stone slurry!
Ying Chengyu continued to walk downstream along the pipe, and said as he walked: "The calcined clinker will flow all the way along the pipe to this place to cool."
"Then the craftsmen will cool the clinker." After the clinker is crushed, it is crushed with a water hammer, ground with a water mill, and finally mixed with slag powder in proportion. "
"The final product is called cement!"
" Although this cement is not of much use at the moment, it is enough to support my daily transportation.”
“When I master the art of steelmaking, I will study it more.”
The cement refined in this way is enough to meet Ying Chengyu's current requirements, allowing a fully loaded trolley to travel like wind and fly on the cement road!
But it is still far from being able to build high-rise buildings and support high-speed driving of vehicles weighing several tons, and it can make countless big teeth of civil engineering brothers laugh out loud.
So in Ying Chengyu's view, this method is only for temporary use.
When the art of steelmaking is perfected and Daqin is able to manufacture steel bars on a large scale, Ying Chengyu will take time to research a better cement production method that is suitable for Daqin's productivity!
However, what Ying Chengyu said only made the monarchs and ministers of Qin feel incredible and incomprehensible.
Han Cang's fingers slid across the blast furnace, across the water mill, across the stone mill, and finally pointed at the cement powder. His eyes were full of puzzlement and he asked: "Chang'an Jun has spent so much effort and used a lot of manpower, but he still only made it." I have made some powder, and there is no time to build the road!”
“So, Mr. Chang’an is not satisfied, and he still wants to continue to study the art of making this powder?”
“So, Mr. Chang’an still said. Only a few hundred people were used to build the road outside the workshop?”
If Ying Chengxuan hadn’t mentioned ‘road-building materials’, the monarchs and ministers of Great Qin would never have thought that the final product of this assembly line would be used. Materials for building roads - one!
It is first hammered and then ground, and the iron-making method consumes a lot of fuel and fired at high temperature. After the firing is successful, it is hammered and then ground again.
If Ying Chengyu had not developed the flat wheel water mill and the vertical wheel water mill, at least thousands of people would have been needed just for hammering and grinding.
After this set of operations, it only produced some powder.
It was not so troublesome for Da Qin to forge armor and weapons!
Ying Chengxiao smiled and said: "The cement powder has done its job. Is it still far from building a road?"
"Brother, colleagues, please!"
Taking a final shocked look at the complicated production line, Han Cang followed Ying Chengxuan closely and followed Ying Chengxuan towards the east gate of Lantian Workshop.
When Ying Chengyu and Ying Zheng stepped out of the east gate side by side, five hundred strong men outside the gate hurriedly raised their hands and shouted: "I humble myself to pay homage to the king! Pay homage to Lord Chang'an!"
Ying Zheng smiled and nodded: "Excuse me, everyone."
"Are you here to build roads for Lord Chang'an?"
Five hundred strong men accompanied him and responded cautiously: "Of course!"
Ying Zheng bowed his hand and said sincerely: "Thank you for working late at night. It is really my loss." You guys have two days of rest after your work.”
Originally, the five hundred strong men were a little unhappy because they had to work late at night.
Now when they heard what Ying Zheng said, the five hundred strong men were at a loss: "This, this, this, working for the king and Lord Chang'an is my duty, how can you do this to us again?" A big reward? "
"That's a hundred dollars! We are just building roads late at night, how can we get the reward that we usually only get in seven or eight days!"
"Since your Majesty and Lord Chang'an have orders, you should obey them. If your Majesty gives you a reward again, I won't feel at ease with it!" You must work hard!" "Please cheer me up and be motivated."
"As long as the two or three sons work hard, the reward from the king will be what you deserve!"

Hearing what Ying Chengyu said, the five hundred strong men were a little embarrassed but happily held their hands in their hands and shouted: "We must fight with our lives!"
Ying Chengyu nodded happily: "Very kind!"
"Brother?"
Ying Zheng was a little funny when he heard this, but he followed Ying Chengyu's wishes and shouted in a deep voice: "Password My order!"
"Changlan Avenue, start construction!"
With the order, thousands of guards came out holding torches to disperse the deep night for the craftsmen.
Zhang Han, Liu Ji and ten craftsmen came out and walked towards the young men.
Under the assignment of Zhang Han and Liu Ji, the five hundred strong men and ten craftsmen were quickly divided into three groups.
Two hundred strong men holding hatchets, led by a craftsman, cut down all the shrubs and trees on the planned route.
Two craftsmen held lime powder and followed two hundred strong men, carefully drawing the edge of the cement road along the predetermined route.
Two hundred and fifty strong men holding iron shovels worked hard to remove the soil within the area selected by the lime powder, and piled the removed soil layer on both sides of the lime powder to raise the road shoulders.
Another fifty strong men quickly ran into the workshop.
Seeing this, the monarchs and ministers of Great Qin felt quite calm.
So far, Ying Chengyu’s method of building roads is the same as the method of building roads in Da Qin today!
If Da Qin's road construction method is followed, the strong men will continue to dig deep into the soil until they can't dig anymore.
Then all the weeds and cut trees along the way will be piled on the excavated soil layer and set on fire. After the grass seeds and insect eggs in the soil layer are burned to death, they will be piled up and set on fire. The soil layer is backfilled, compacted, backfilled, compacted, and the cycle continues.
However, when the hundreds of strong men rushed out of the workshop, the situation on the scene became different.
Under Han Cang's nose, a strong man sprinkled a cart full of cement powder on the ground.
Han Cang immediately became anxious: "Be careful!"
"It is quite difficult to make this thing. Even if it is sprinkled on a cart, it is a huge waste!"
The strong man pushing the cart looked back blankly, showed Han Cang a naive smile, and then ran away pushing the cart!
Han Cang was extremely angry and laughed back: "Hey!"
"You..."
Before Han Cang could finish his words, another strong man pushed a cart full of river sand and ran to Han Cang. In front of Han Cang's eyes, he poured all the river sand on the cement powder!
Han Cang:? ? ?
In the astonished eyes of the monarchs and ministers of the Qin Dynasty, four strong men came running up with carts one after another, and sprinkled three carts of stones and half a cart of river water on the cement powder that had been made after all the hardships!
Seeing this, Han Cang finally understood: "Are they further processing the cement?!"
Ying Chengqiao smiled and nodded: "Han Shangqing is a great talent."
"As Han Shangqing said, sand and gravel need to be added to cement before building roads."
"This is not only to reduce the amount of cement and fill the road with simpler and easier-to-obtain materials, but also to allow They act as supports like bamboo pieces in the wall, making the road more solid."
However, listening to Ying Chengyu's explanation, Han Cang couldn't laugh at all, and shook his head repeatedly: " Cement is difficult to make, and it needs to be prepared after it is made. I don’t know how much manpower is wasted! ”
"Looking at the color of this paper (paste), it is quite similar to the surface of the road just now."
"I think Chang'an Lord tamped this road back and forth like building a chimney, and then dumped this thing on The surface of the road is as hard as gold and stone!”
“Chang’an Jun can make the road smooth and hard by using this method, but it will definitely cost a lot of money!”
"It is even more impossible to build a road of more than ten miles with just a few hundred people in two months!"
While Han Cang was questioning, the strong men had already dug out a section of the road. A pit about three feet long and one foot deep.
Fifty strong men were quickly separated from the excavation team, holding planks and ramming pestles to simply tamp and level this section of the road. Six craftsmen placed one-foot-wide planks along the route drawn with lime powder. Within the pit.
As Han Cang, Zhao Cheng and other courtiers looked on in shock, a dozen craftsmen directly poured the mixed cement into the pit!
Zhao Cheng pointed at the cement and looked at Ying Chengyu, his eyes filled with shock as he asked: "Chang, Chang'an Lord."
"Pour it in like that?"
Ying Chengyu nodded naturally and said: "Ang!"
"It just poured in."
Zhao Cheng's eyes widened even more: "There is no need to dig deep into the hard soil, and there is no need to backfill with mature soil and compact it repeatedly."
"It's just that After digging out a foot of soil, just pour this stuff into it?"
Ying Chengqiao nodded confidently: "Ang!"
"Otherwise, I don't have enough manpower. How to save time! ”
