Roland stood in the backyard of the firing room and waited for the first batch of cement to come out.
This brick house was designed specifically for cement production, about fifteen meters long and four meters wide.
There is a door in front and back, the difference is that the front door is as spacious as possible for people to carry materials.
The back door is only one person wide, allowing Anna to sneak into the firing room.
To this end, he also built a circle of walls at halfway up the house, surrounding the back half of the firing room, and arranged for knights to guard them from the import and exit, and they were all under Carter's subordinates, and their loyalty was unquestionable.
The production process of cement is very simple. The limestone is crushed into powder and mixed with clay and iron powder, calcined into clay by dry or wet method, and then grind it with gypsum to use.
The raw materials are very ordinary, and it is difficult to make large quantities of iron powder and can be left unused. The key lies in the calcining temperature of the clinker.
Roland doesn't remember the specific temperature required for firing cement. Even if he remembers, he can't measure and control the temperature, whether it is an infrared thermometer or a thermocouple thermometer, it is countless times more complicated than cement.
He only knew that this temperature was almost similar to the melting point of iron, and the calcination process was also a difficult task in producing cement.
In the era of underdeveloped smelting technology, maintaining blast furnace temperature has always been a problem that plagues everyone.
The heat loss of ordinary open furnaces is extremely large, and it is difficult to keep the furnace temperature above 1200 degrees.
The reflector also needs a high-temperature resistant inner liner, so he couldn't think of how to build refractory bricks for a while.
Traditional iron-smelting blast furnaces are even worse. The temperature may meet the standards, but relying solely on the narrow and long furnace chamber to calcinate the cement, I am afraid that I will not be able to burn enough when the evil moon has passed.
Therefore, the firing room designed by Roland did not have any heating measures at all, and he relied on Anna.
The small-grain limestone that has been artificially broken is mixed with clay and mixed with water to form a slurry, and evenly spread in the firing room.
Then the knight locked the door and cleared the handyman away.
Anna entered through the back door and let the flame bake the slurry on the floor until the iron rods placed in the room melted.
Roland was a little restless, which was his first step to stationing in the border town.
If cement cannot be made, the plan to build a city wall in three months is just empty talk.
There is no city wall to block it, I am afraid no one is willing to stay in this ghost place.
Whether it is real history or fictional literature, if you want to farm well, a stable base is essential.
Your Highness, what you are talking about really sticks all the stones together?Carter Lannis, who was standing beside the Fourth Prince, asked.
Although the prince told him that this was the latest research result of the Grayburg Alchemy Workshop, he was still skeptical.
After all, those people have never made any truly reliable alchemy products.
Who knows?That's what they said anyway.Roland spread his hands.
In this world, alchemy and astrology are called the sage art together and are very popular in mainland countries.
The royal family usually trains their own alchemists and astrologers to refine secret medicines and predict fate.
For ordinary people, these studies are too high and have developed a blind faith.
With this in mind, Roland naturally led the question of the source of cement formula to the alchemy workshop.
As for whether the Chief Knight believes it or not, it doesn't matter at all.
The flames that emerged from the window gradually faded, and it seemed that they had been burned.
Roland stood up and drove Carter out of the yard, waiting alone in front of the back door of the brick house.
The iron door was pushed open with a creak, and Anna walked out naked.Roland immediately put his robe on her and brought her a glass of water. How about it?
The witch's body was scattered, and although the wet cement was low in dust, the scorching air during calcination would still bring dust.
For her who cannot wear a mask, it is obviously not too comfortable to stay in it for dozens of minutes. The gray dust covered her white skin.
She drank water so much that she coughed too quickly. The water slid down from the corner of her mouth, taking the dust away along the concave and convex body curves. The water marks exposed the delicate skin again, and the contrast of the gray skin revealed the same temptation. Roland found that she could not move her gaze at all. It was not until Anna finished drinking the water that she smiled and looked away.
Everything is put by Your Highness’s affairs first, and I don’t feel embarrassed. Why is Your Highness embarrassed?
Anna felt the heat coming from her lower abdomen, and the magic in her body became active again. She knew what Roland was focusing on and said in a casual tone: It has been burned into powder.
Roland couldn't wait to get the temperature low enough during the firing, so he wrapped the wet towel around his head, grabbed a shovel and drilled into the back door.
The hot air surrounded him instantly. He felt a little difficult to breathe for a moment, and the skin on his hands was so baked.
Fortunately, it won’t take too much time to shovel a handful of dust, otherwise staying in this environment for a few minutes will probably cause high temperature shock.
The wet towel stroked Anna's body, peeling the dirty dust off her beautiful body, as if it was because of a good diet. Her originally thin and malnourished body had plump. Her plump breasts were shimmering after being wiped, and her rosy nipples were even more delicate, like buds waiting for others to bloom.
Unfortunately, no one appreciated this beautiful scenery. The witch gradually bloomed like a nourished flower. After rubbing her upper body, Anna changed into a towel and began to wipe her lower body. With a slight force, the two plump labia were squeezed together. After being wiped hard for a few times, it returned to its original state again. It was closed tightly to protect the delicate hole. Is this still the vagina that could not be closed because of Roland's rough fucking before?
Is this what you want?Anna asked after putting on the witch suit and stretched her head over.
It looks very similar. Roland flattened the powder and felt its residual heat with his fingers. It still needs to try to find out whether it works.
What is its use?
There are too many places to use when building houses, bridges, and roads.If it succeeds, people's residences will not be afraid of wind and cold, and they will not be destroyed by heavy rain and heavy snow.He patted the girl on the head with his other hand, it was done by you.
Anna lowered her head.I don't know if it was an illusion, but he felt that the girl's breathing had become faster.
Theoretically, the fired clinker must be ground with gypsum to adjust its hardening time.
But there was no need to think about it at this time. Roland took a short rest and shoveled out two more hands, then called Carter and asked him to prepare cement mortar in the ratio of three portions of ash powder mixed with river sand.
The Chief Knight didn't mind doing some rough work at all. For him, doing such things was much better than fighting for His Highness or hooking up with a noble lady on a trip during Gray Castle.
Since no iron powder was added to the raw materials, the cement slurry produced was light in color and appeared grayish white.
Roland poured them all over one stone brick and then buckled the other one.
The cement settling time was about four hours. Considering the instability of the trial products, he planned to wait until tomorrow to see the results.
The next morning, Roland hurriedly took Carter and Anna to the backyard of the fired room.
Pushing open the door, he noticed that the cement surface was already solidified and closely connected with two stone bricks.
The consolidated surface looks uneven and white frost appears on some locations.
Roland squatted down, scraped off the white frost produced by the alkalization reaction, and pressed the hardened cement with his fingers. The touch made him feel happy that the cement surface was strong and uncomfortable, which was completely different from the touch after the soil was compacted. Even if he used his nails to buckle it hard, he could not leave a trace on it.
After receiving the instructions from the fourth prince, Carter first tried to lift the stone bricks, but failed.
He kicked hard from the side several times until the junction between the cement and the ground broke, and the two stone bricks were still firmly bonded together.
Finally, he waved the hilt of the sword and hit them hard, and could only knock down a small piece of edges and corners.
Is this the effect of cement? Carter immediately realized its effect, which was incredible.Yesterday it was still flowing like a melted candle, and it became as solid as a rock in just one night.With such things, the city wall can be built as fast as you want.As long as there are enough stones, we can even build a city wall around national borders within five years!
What's the use?Roland disagreed. No matter how tall the wall is, it cannot stop the enemies from inside.I would rather turn the dilapidated wooden houses in the Border Town into solid cement houses so that my subordinates no longer have to worry about falling into a homeless situation after a natural disaster.
... The chief knight was stunned. He really didn't expect the fourth prince, who was a combination of various noble habits, would say such words.
You will see it later.Roland once again affirmed the path he was going to take. For many time travelers, technology is the primary productive force.And here, witches are the primary productive force.
