Chapter 63: The Birth of Cement
"Bang-bang-bang-"
Under the blazing fire, the steam engine was quickly activated, and the flywheel at the side tail was driven by the crank to spin rapidly.
It rotates much faster than before, and with the help of a special power adapter, the crusher on the side is also slowly driven.
The overall structure of the stone crusher is a square, two meters high, one meter five in length and width, and has an inverted pyramid-shaped funnel above.
This is the entrance to the crushing of the stone, into which Goodern pours a pot of dug lime ore.
As the lime mine collided with the reamers inside, the sound of clattering continued to sound from inside the stone crusher.
In order to ensure strength, the reamers inside the crusher are all made of manganese steel, and the internal reamers have ten layers.
The speed of the reamer is inconsistent in each layer, and the speed of the reamer in the top layer is only 30 revolutions per minute, which is one revolution every two seconds.
The second layer becomes 45 revolutions per minute, the third layer is 60 revolutions per minute, and the last layer is 120 revolutions per minute.
Reamers of different speeds are used to process different sizes of ore, and most of the heavily crushed lime ore will be reduced to granular powder, and a few will be the size of rice grains.
But this is not the end of the process, there is also a built-in roller roller compaction member at the bottom of the crusher.
The crushed limestone slag undergoes a second round of crushing, after which the lime powder is poured out of the prefabricated outlet.
A basin of limestone was processed in less than 30 seconds.
Looking at the still slightly rough lime powder, Goodern is already very satisfied, and it is not far from the birth of cement to be able to reach this step.
Immediately, part of the prepared iron ore is also put into the stone crusher, and in addition to lime powder and clay, a little iron powder is required in the production of cement, which can also be directly replaced by iron ore slag.
At each turn, iron dust made from iron ore pours out of the crusher.
The raw materials are simply weighed, mixed in proportion, and calcined in the furnace of the blacksmith's shop next door.
This process does not take too long, and with the help of high temperatures, the three materials are fused with each other to form cement clinker.
At the end, the calcined clinker is put back into the crusher to be crushed into cement powder.
As soon as the grey cement powder came out of the crusher, Goodern was eager to put it to the test.
Add water and stir well, then glue the prepared bricks layer by layer.
Under Goodern's command, it didn't take long for a half-meter-high brick wall to appear.
Then the remaining cement was evenly applied to the wall, and the familiar cement wall was born in another world!
Goodern glanced up at the midday sun, and according to this situation, it is estimated that by the evening, the cement will be able to dry, and the hardening test will probably have to be scheduled for tomorrow.
For the cement test, Goodern is not worried about accidents, after all, from the production to the finished product, there are no abnormalities.
In the worst case, the proportion of cement ash is wrong, and it can be adjusted slowly when the time comes.
In order to avoid the curiosity of the crowd from destroying the strength structure of the cement, Gooden directly ordered it to be restrained.
"From now on, this wall is now forbidden to anyone to come close to it, and we will test it tomorrow morning after the cement has hardened."
"Yes."
In this context, his words can be equated with the law.
Therefore, after receiving the order, everyone took a step back and said that they would not come closer.
"Buck, you have bothered to sort out the design drawings of the stone crusher in the past two days, and at the same time divide the personnel of the research institute into two groups."
"Two groups of people are divided into groups to build steam engines and stone crushers at the same time, Pansy and Eden will give them a little bit of a pick, so that they can be your deputy to develop the team."
These days, Gooden has not forgotten to refresh the entries for the apprentices of the Academy of Engineering, and has found two good seedlings as alternatives.
When Buck heard that an apprentice could be ordered, a happy smile immediately appeared on his face.
These days, he is under too much pressure on the development task.
Although many of the complex crafts were completed by the young master with the help of magic, at least two-thirds of the remaining part was forged by his own hands little by little.
Now that he has a deputy to help, even if it is only half of his skills, the rest of the work will be much easier.
"Pansy, Eden, I'll learn from the young master later, and when you come back, you will be responsible for the creation of a project."
The two men named by Buck hurriedly lined up and followed Goodern back to the castle.
According to the old way, Gooden is still a turnip and stick move, pushing the loyalty of the two to about ninety and then modifying the entry.
After the entry was modified, the two looked at each other in shock, and then hurriedly expressed their loyalty.
Seeing the rapidly rising loyalty, Gooden was satisfied that the two returned to the Academy of Engineering to continue their work.
……
Early the next morning, Goodern took Joseph Sr. and a few soldiers to test the cement brick wall.
After almost a day of drying and hardening, the cement paint on the front of the brick wall has become very hard.
On the other hand, the uncoated part of the back shows that the bricks have been firmly bonded together by the hardening of cement.
"Come two people to hold the side, Els come and kick it and see, don't use all your strength."
Gooden used the simplest and most violent way to test the hardness of cement, originally intending to test it with a rifle.
But after thinking about it, this thing can even penetrate manganese steel, and it is really too much to test cement brick walls, so I use the method of 'manual inspection'.
The brick wall has no fixed foundation, so someone has to hold it to prevent it from being kicked down.
As Goodern had requested, Els came to the edge and kicked the brick wall with three or four points of force.
I thought that this weak brick wall would shatter when I stepped down, but I didn't expect it to leave a slightly dented gray mark on the concrete surface.
"Raise it to seven or eight points of strength and give it a try."
Looking at the imprint on the wall, Goodern was slightly intrigued and asked Els to raise his strength and try again.
As Els's strength increased, this time he directly kicked the cement gray surface directly, revealing gray-red bricks.
And the wall is still 'standing' at this time, and it doesn't seem to be a big deal.
"Take a few steps back, run and kick with all your might."
With the help of running and pushing with all his might, the thin concrete wall was finally kicked and opened as Els wished.
The surrounding onlookers looked at the cement blocks scattered on the ground with incredulous expressions.
They didn't expect this thing to have such a high hardness and adhesive effect, just this thin layer, even the soldiers under the young master had to run with all their strength to kick it away.
If there are a few more layers, who else can destroy this?
For the role of this new material, everyone has thought of a lot of application directions.
