How is cement made?

Before making cement, it is important to know what the raw materials are, clay, lime, and iron powder.

Among them, some materials are substitutable.

"Clay is a clayey soil with few sand grains, and water is not easy to pass through it and has good plasticity, which is generally formed by silicate minerals after weathering on the surface of the blue star, and is composed of a variety of hydrated silicates and a certain amount of alumina, alkali metal oxides and alkaline earth metal oxides....... Forget it, we don't need to know this. ”

In the game, several players look at the garbage while operating, and at the same time chanting words, they can't help but have confused expressions.

"You know that limestone turns into quicklime, right?"

After thinking about it, the garbage decided to pick a simple question.

Ji Yuan and the others pondered again.

"I'm sorry, if I was still a junior in high school two years ago, I could have easily answered you, but I'm a sophomore now!"

Cherry said with a serious face.

Litter:........

"High-temperature calcination."

The garbage face is expressionless, asking and answering itself.

"Quicklime can be obtained by calcining limestone at high temperatures, but it requires a temperature of 1,200 °C, unless the era and the sect master use spiritual power to induce combustion, we can't reach the required temperature with firewood alone."

"At the same time, if we want to calcinate iron, we need to calcine it at high temperatures."

After twelve hours of training, the physical body of Anno Reality successfully fed back a trace of strength to the characters in the game.

He stepped into the first level of Qi training!

After "accidentally wounding" and picking up three for him, allowing him to consume a chance to resurrect, the era also became proficient in spiritual power.

"So, we need coal and charcoal, and needless to say, coal doesn't have it."

"There is no natural charcoal, but we have enough wood to burn charcoal!"

With that, the garbage instructed a few people to throw all kinds of small dry firewood, as well as coarser wood, into the blast furnace.

Xu Hao used the power obtained during the foundation building period to release a true qi, which attached to the firewood and then burned.

This is the spiritual power that can be changed to the five elements, that is, the consumption is a little large, but correspondingly, the power is also great.

Rumble!

From the blast furnace came the business of burning more and more flames, like a fiery snake, rushing upwards.

Gray, powdery plant ash begins to fall gradually underneath the blast furnace.

The garbage looked at another blast furnace full of wood.

"Era, it's been simmered for too long, but the carbon rate is very low if it is not simmered...... You know what I mean!? ”

Trash looked at Eno and raised an eyebrow.

Era:.......

The corners of his mouth twitched, and then he resigned himself to controlling the transmission of a trace of spiritual energy into this blast furnace.

A few hours later, Kino sat cross-legged on the ground with a pale face, still with a loveless expression on his face.

It's true...... Not a trace of spiritual power is gone!

Since the garbage knew that he had broken through in the morning, not a trace of the aura in his body belonged to him!

Especially when it comes to knowing that spiritual power is almost omnipotent......

The garbage dismantled the sealed blast furnace, which was full of charcoal still burning.

"Don't take it out, add iron ore, let's make iron first!"

Chang'an, which organized the preparation of the charcoal, threw a few pieces of iron ore into the blast furnace with garbage.

Originally, they didn't have iron ore yet, and they were going to make shoddy cement, but Cherry said he seemed to have seen it!

I followed the place where Cherry said, and sure enough, I found a small iron ore in the open air!

It just so happened that there was not much demand for this thing at one time, so he returned to the garrison with a bunch of them.

"And mud."

Watching the charcoal burning, there was no accident, and the garbage looked at the burned plant ash next to it.

There were no containers or mud, so the garbage simply smashed a small pit in the ground with an axe, and then carried the grass ash into the pit.

Soak your clothes in the water of the river next to you, soak them and place them above the hole.

Wring it out vigorously, and the water in proportion to the ashes of the plants and trees drops inside.

Then use your hands to mix mud in it to make the grass and wood ash into a muddy shape.

After a while, the ash settled, and the garbage was dug into a small downward ditch, allowing the potash water floating above to flow out of the ditch and surface the mud below.

Holding the ashes of the plants and trees with both hands, the excess water in the mud was vacated, pinched into balls, and then got up to see the appearance of the iron ore.

Shisan has been blowing air with a blower made next to him, so the calcination of iron ore is very fast.

Iron ore, which was originally one, has now become a lumpy stone with distinct iron substances and impurities, but they are glued together.

Gently striking the stone with a stone, it suddenly shattered into pieces of rubble of different sizes.

The garbage smashed the black, hard pig iron on it and threw it aside, and the useless impurities were thrown aside.

"Now it's time for a second calcination."

Last night, the garbage threw the grass and wood plaster slurry that had dried the excess water into the blast furnace and continued to calcin.

After a while, the spherical mud comes out of the oven, and the garbage grinds it into powder.

Mixed with clay fished out of the river, some uncalcined iron ore was ground into powder and mixed in it.

"In fact, it is okay not to mix with iron ore powder, but with iron ore powder, it can be hardened better."

Looking at the puzzled eyes of everyone, the garbage explained.

He squatted there alone with the ash cement of the grass and trees, and a bunch of onlookers next to him, including Xu Hao, also watched with relish.

The garbage smeared cement between two huge stones and made them stick together.

While the cement was dry, he put the calcined pig iron into the blast furnace and continued to exercise on the fire!

After a while, he took out the pig iron, removed the outer layer of impurities, and then put it into the blast furnace again to calcin, and so on.

In the end, he got a large piece of iron, which was not very shoddy.

It is heated again at a high temperature to make the iron plastic, and the garbage is beaten and beaten, and finally becomes a one-meter-long, thin coarse iron rod.

And out of the remaining iron, he made a meniscus scythe that didn't open its edge.

"Weapons are given to high-ranking people first."

Handing the iron rod to the pale face couldn't hide the excitement of the era, and the scythe was handed to Shisan.

Cherry and Chang'an said they had no doubts.

Looking at the last piece of iron, the garbage thought for a moment, and finally forged a claw hammer for himself.

Iron rods, sickles, hammers, and iron ore powder, all four things will consume all the iron ore they have brought.

At this time, ten hours had passed, and everyone went to check the situation of the grass and wood ash and cement.

"Knock Knock !!"

The garbage struck against the two stones glued together with the cement as several people watched expectantly.

After the knocking, only the marks of the hammer were left on it, and the cement did not change much.

Everyone is happy!

"In fact, general cement still needs more materials and steps, but we lack a lot of things, not even gypsum, so we can only make it hastily like this......"

"But at present, it seems that the effect is good, and the grass and wood gray cement can be used as the most important building material at present!"

Trash stood up and looked at Xu Hao, with a smile on his face.

"Sect Master, build a cement !! for the revival of the sect"

Revive a hammer!

Xu Hao complained wildly in his heart, but he had to put on a touched expression on his face.

"Yes, if everyone is like you, with such an awareness, why can't I be too happy to be happy!!"

"You've done a great job developing... Well...... Ancient materials, cement, have a great contribution to the sect! ”

"Get a reward, get a big reward!"

Xu Hao's face was very serious, and then he waved his hand and took out a handful of banknotes from his body.

"In addition to the 1,000 meritorious deeds promised to you before, I will also reward you with 200 bronze tickets in my personal name!"

Bronze ticket?

Everyone was stunned for a moment, and then thought of a possibility, and the whole person became excited.

"In the sect, you can use the copper ticket to trade with other fellow sects, these two hundred copper tickets are not much, but it is also a little bit of my heart, you can take it!"

Trash excitedly took four bronze tickets with a denomination of fifty, and his face was flushed.

Just when several people in Chang'an were about to borrow it to observe, Xu Hao's words made them completely excited.

"This is the elixir I refined, and it is also a little bit of my heart......"

"The quality of the pill is very good, and the medicinal power is very sufficient, which is very suitable for improving your strength now."

"Take it!"
