People are in the court, and the queen is a faint king

For the time being, we can't take care of the border affairs.

Mu Yu began to run around for the task,

In the Ministry of Industry, outside the capital, running back and forth.

Finally, the task of cement was finally completed.

And also understand why to look for coal.

Because quicklime is used in the production of cement, and calcium carbonate is also stone, and high-temperature calcination is required to turn calcium carbonate into quicklime. Note that it is high-temperature calcination, which is difficult to achieve in general wood burning. Coke, that is, coal is required. , and not so long ago, coal was basically unusable in this world.

Mu Yu suddenly understood why there is no cement in this world. One of the important reasons is that there is no popularization of coal.

Once you realize this, it becomes incredibly easy.

Mu Yu quickly found Lao Yu, Shangshu of the Ministry of Industry.

In this era, there is rammed earth, and there are other ways to make buildings.

The first method is lime sand, which uses lime mortar to consolidate buildings, and lime mortar is actually a mixture of lime and sand plus water, which is low-tech and low-cost.

Therefore, when Mu Yu said that he wanted to reform, Lao Yu didn't pay much attention to it.

Although lime mortar has a big weakness, that is, its strength is not high, it is difficult to build those very tall buildings, and it cannot be used in a humid environment, and it is very afraid of water, but its cost is low.

In addition, there is another way to build tall buildings in Daluo, such as city walls.

This method is to use glutinous rice mortar to build. As the name suggests, glutinous rice mortar is a mixture of glutinous rice and lime mortar. stickiness.

Walls, city walls, houses and the like built with it will be very, very strong.

How strong is it?

......................................

The Great Wall of the Qin State was built in this way, and it will not fall down for a thousand years. It is so strong that when an engineering team wants to demolish the bridge, an iron drill can hit it, and it can hit the strength of sparks.

Plus, there's one last way...

Even rammed earth, red mud, coarse sand, and lime are quickly mixed together, and the solid material formed by gravity pressure can also be used. There are all kinds of materials. Of course, Lao Yu is very concerned about the improvement that King Jing said. Although he admires the latter, it doesn't mean that it will work every time, especially in Daluo where the building materials are already very developed...

It is impossible to have advanced reforms.

However, Mu Yu quickly slapped him in the face with the facts.

If there is volcanic ash, use volcanic ash, if not, use limestone, add clay to grind and then calcined, the temperature is more than 1400 degrees.Then fill it with gypsum and grind it into powder, probably enough.But pay attention to the composition ratio of various materials.

Cement, soon followed by the world.

"This..." After seeing the effect, Old Yu took a deep breath.

The role of this cement is too great. Composing concrete can save a lot of manpower and material resources, and rammed earth is to ram the soil together layer by layer. It is time-consuming and labor-intensive, and it is extremely slow, and only one place can be built. Ram one place, and glutinous rice mortar is costly and expensive...

But once the cement appears, it can be fired at the same time. When it needs to be used, add sand, etc., pour it into it, and it will solidify in a short time, which can save a lot of time.

However, it is not very useful to repair city walls, but it is extremely valuable to fix bricks quickly when used to build houses.

Then, is Brick Fast.

As soon as Mu Yu mentioned that he wanted to popularize bricks quickly, Lao Yu shook his head directly.

But soon, Lao Yu thought of something and his heart trembled.

If it was before, it would be impossible.

Bricks, whether they are high-quality blue bricks or poor-quality red bricks, can only be used by high-ranking officials, even the royal family, because the white charcoal used to make bricks is extremely expensive... …

But now...

"Coal..." Old Yu gasped: "Why did the old man forget this recommendation? In this way, it can be popularized, it can be popularized, the price can be greatly reduced, and the common people can afford it, even You can build brick houses and burn them everywhere..."

Mu Yu also laughed, these two tasks are much easier.

As long as coal is popularized and developed, it can be done.

PS: Thank you [Chengbei Qiaokong] boss for the thousand-point reminder ticket, and thank you for the reminders, monthly tickets, and rewards from other bosses, thank you!seven.

Chapter 137

Regardless of whether it is blue bricks or red bricks, the firing price is extremely high, and it was impossible to fire cement before, but with coal, these problems are easily solved.

Especially Daluo coal mine is very rich in resources.

"In this way, bricks will soon be popularized, and most ordinary people can afford it... It seems that it is not enough, the price of blue bricks is expensive..." Lao Yu was sometimes ecstatic and sometimes confused.

Mu Yu smiled and said, "Why do you have to use blue bricks?"

"If you don't use blue bricks, what do you use?" Old Yu was at a loss: "The quality of blue bricks is better...Could it be, use red bricks?"

"Of course use red bricks." Mu Yu nodded: "The firing process of red bricks is much simpler than that of blue bricks, and...Although there are many shortcomings, Yu Shangshu, did you forget about cement?"

Yu Shangshu was taken aback.

Red bricks can also be fired, and the production process is much simpler than blue bricks, but also, the quality will be much worse. Green bricks can last for thousands of years without breaking, but red bricks are different. Afraid of cold, easy to crack, fragile, and because of the craftsmanship, red bricks with uniform color and luster cannot be cast, which hinders the appearance, so Yu Shangshu did not consider mass production of red bricks for a while.

But now I suddenly remembered, yes, there is cement.

As long as the cement is applied on top to seal the red bricks, all the problems of fragility and different colors are solved.

Yu Shangshu was slightly startled, then nodded with bright eyes.

"It's not just for the common people. The use of this cement and the red brick are too great. Once it is popularized, it will be of infinite use..." Yu Shangshu's eyes were lost.

However, at this time.

Mu Yu received a reminder that the task was completed.

"Ding, you have received the following task rewards."

"1: Lifespan +25."

"2: Martial arts talent +30."

"3: Strength +20."

"4: Cultivation talent +25,"

"5: Spirit +2."

"6: Aura +1."

"You have received the following rewards."

"..."

"Aura +1."

……

Soon after.

The Ministry of Industry took the lead in starting, trying, improving, and then, taking the lead in including those Baixing whose houses collapsed in the snow into the list of trial production... and began to try.

a few days later.

Outside the capital city, on a site where the snow has been cleaned, a one-story red brick house was slowly formed with the help of cement and gray sand, two meters high and three meters wide.It is five meters long and occupies quite a large area... Moreover, since the Ministry of Industry personally made it this time, the red bricks made are all high-quality products with uniform colors...

However, the only troublesome thing is the roof. After repeated discussions, it was decided to use the traditional old test roof, because there is no such thing as steel bars in this era, and if the roof is made of cement and sand, it is easy to break and fall. The iron and steel properties are not enough... because, it is made of wood, and the roof is covered with tiles...

And this is already an extremely amazing building.

Ordinary people, in the past, did not dare to think that tiles are also very expensive. Now after coal is developed, it is not as difficult and expensive as charcoal. After removing this important task, it has become extremely cheap , a house, more than half of it was built soon...

However, the people who lost their homes in the snow, touched the red bricks of their house in a trance, touched the ditches in them, the traces and intervals between one brick and another, and their eyes became more and more trance.

He thought of the nobles and dignitaries in the capital...

In the past, this was something he could only hope for... Only the courtyard walls of wealthy and powerful families could afford to use green bricks... Common people, just look at it... But today, he also has his own brick house ...Don't worry anymore, it's crushed by the snow...

Afterwards, the cement began to be plastered, the inner floor and the outer floor, and a house with a somewhat modern atmosphere came out...

Seeing the effect of the cement, the people were stunned.

However, many officials of the Ministry of Industry also stayed.

After this trial, the cement and red bricks have been completely successful, and they will be promoted in the whole country immediately...

After completing these two tasks.

Mu Yu approached Her Majesty the Empress.

The night is deep.

The Empress is still processing the memorial.

Her hair was scattered on her forehead, and her brows were slightly furrowed.

"Yi'er, it's time to accompany your husband." Mu Yu leaned over.

Some trance.

"The lonely king will finish his work first... the border affairs are difficult to solve..." His majesty frowned, and said: "The lonely king also wants to be with your husband...but state affairs are also very important."

"Then, my husband will go to the border gate in person, sit there and take charge of the overall situation." Mu Yu expressed his thoughts.

"Husband, you, what are you talking about?" The empress suddenly turned her head, and then slowly shook her head: "Husband, no, the border is dangerous, and the lonely king is also reluctant to leave you..."

If you can go to the border, it can indeed solve some major problems, such as the situation that the information is not delivered in time, and the decision-making is slow...Sometimes, the King of Zhennan can't be the master after all, and the information transmission is slow... This is also the reason why many His Majesty, the emperor's personal conquest , to make a decision at the first time... But, go to the border... It has not yet reached the point where the emperor of a country needs to personally conquest

"Speaking of reluctance, but you haven't slept in a few days?" Mu Yu smiled: "I can't bear my wife to work so hard for my husband... I will accompany my husband tonight... Leave the border affairs to me."

"Yes, but..." The empress thought for a while: "No, the lonely king is reluctant, no."

The Empress disagreed with Ben.

Mu Yu frowned.

Without waiting for the empress to say more, Mu Yu picked her up by the waist, and amidst the latter's exclamation, brought her to the bedroom...

The next morning.

As soon as Mu Yu got up, he was ready to go to the border in person, get into the chaos in person, go to the border to take the lead, and take charge of the war...

In fact, he may not go for the time being...

Yes, one is that the system issued a task.

Second, the battle was too fierce.

Today, although Da Luo's national strength is strong, it is not enough for the popularization of blacksmith shops.

Third, is one of the most important points.

Side quests.

Zhuge Liannu's mission request was to ask him to personally go to the border and lead the troops for a period of time.

In the end, it was because of Your Majesty... the situation at the border might not be that dire, but it was not going well, and the empress worried about it every day... it will be resolved in the end.

Various factors are the reason why King Jing is determined to go to the border and participate in the war in troubled times...  

Otherwise, he doesn't want to leave Daluo...

The night before leaving.

Mu Yu, Chang'er, Yan'er, and the Empress stayed together for a whole night... and then left with Chang'er, who was at the top of her martial arts.

And early in the morning... the news came out...

The whole Daluo shook.

The faces of many court officials changed drastically...

He abruptly pulled Emperor Jing back.

There was a lot of discussion in the court, and everyone had seen it.

All but one opinion.

That is, disagree.

And in the capital, many girls' homes, when they heard the news, their eyes began to weep, worrying about the latter...
