Orthodox 10th November, Yushan Workshop.

After Liu Juntao handed over the production method of soil cement to Ma Lijun, Ma Lijun took the craftsmen of the new cement workshop to rush in, and stayed in the cement workshop under construction for more than a month!

During this period, Ma Lijun led everyone to use only one furnace for trial production, and after dozens of failures, he finally experimented with a sample of soil cement.

After Liu Juntao received the news, he immediately rushed to the Yushan Workshop, only to see that Tang Yu had already rushed over early, and was discussing something around a wooden basket with Ma Lijun and other craftsmen.

Liu Juntao hurriedly stepped forward, only to see that a large wooden basket had been filled with cement mortar, and was waiting to solidify.

Liu Juntao took a closer look and saw that this cement mortar was different from the concrete mortar of later generations, there was no stone mixed in it, and the mortar in this wooden frame was relatively thin, not as viscous as the mortar of later generations. In the mortar, there are things such as broken porcelain tiles, which play a supporting role.

Liu Juntao first inquired in detail about the research and development process of this soil cement, and was very satisfied after listening to Ma Lijun's answer, knowing that Ma Lijun was developed and produced in strict accordance with his own methods, and there was no problem with the process and process.

So, Liu Juntao asked: "How long has this basket of cement solidified?" ”

Ma Lijun looked at the special incense plate used to keep time next to him, and said, "Back to practice, it's been more than an hour. ”

Liu Juntao nodded, and said secretly in his heart: "Time is not enough, and the concrete cement of the future generations cannot be completely solidified for more than an hour, not to mention my soil cement, I have to wait for a while!" ”

So, Liu Juntao looked at the sky, and saw that it was close to noon, so he said: "Time is not enough, it is estimated that this soil cement will have to wait a while to solidify, let's eat first, I'm already hungry." ”

In the living room in the cement workshop, Liu Juntao and Tang Yu set up a table, on which a few plates of delicious dishes were already placed, and the two began to eat and drink.

Ma Lijun, on the other hand, was not worried about the soil cement that was solidifying, and insisted on staying at the scene and waiting.

Liu Juntao saw that Ma Lijun was immersed in it and couldn't extricate himself, so he no longer insisted.

After the two of them ate and drank for a while, Tang Yu said: "Mr. Lian, after this cement solidifies, will it really be as hard as iron as you said, and the cost is low and the house is built quickly?" ”

"Of course!"

Liu Juntao said longingly: "As long as our Huangming brand cement can be mass-produced, it will definitely have a huge impact, and then not only will the building technology of Daming all over the country undergo earth-shaking changes, but also the houses that craftsmen can build will be bigger, taller and stronger!" Craftsmen were even able to build towering buildings dozens of stories high! ”

"Dozens of stories high!"

Tang Yu's eyes widened in disbelief after hearing this, he couldn't believe what Liu Juntao said, and said secretly in his heart: "Even those tall towers and carved buildings in Yanzhou Mansion and Jinan Mansion are estimated to be not so high, that is, how many floors, more than a dozen floors, dozens of floors?" How is this possible! ”

However, looking at Liu Juntao's confident appearance, Tang Yu had to believe that after all, some of the things that Liu Juntao said and did before were many things that ordinary people couldn't do, or couldn't believe, but Liu Juntao did them one by one!

Therefore, even if Tang Yu couldn't believe it, he felt in his heart that Liu Juntao would definitely be able to do what ordinary people couldn't, and this soil cement would definitely be able to succeed.

Liu Juntao and Tang Yu chatted for a while, and saw that it was already past noon.

At this time, the two of them had eaten and drunk enough, and Liu Juntao was ready to take another look at the cement in the wooden frame.

Suddenly, Ma Lijun hurriedly ran over and said loudly: "Mr. Lian! Minister! It's done, cement succeeded! ”

Tang Yu also looked at Liu Juntao excitedly when he heard this, and said, "Mr. Lian, we have succeeded!" ”

"Haha!"

Liu Juntao laughed when he heard this, and said, "Let's go!" Check it out! ”

Everyone walked quickly to the wooden frame, Liu Juntao looked at it, and saw that the cement in the wooden frame had basically solidified, like a large rock, which surprised Tang Yu and Ma Lijun and other craftsmen.

Liu Juntao stepped forward and knocked on the cement block, feeling that the hardness of this soil cement was barely qualified, and the setting time was also within the allowable range, but it was a little brittle.

Looking at the cement crumbs on his hands, Liu Juntao sighed slightly in his heart, and said secretly: "This level is okay to build residential buildings, but if it is used to build military facilities such as city walls, it will be a little insufficient, and the hardness is still a little worse." ”

So, Liu Juntao said to Ma Lijun: "Master Ma, this soil cement is a success, but there are still some small flaws that need to be improved immediately by our workshop." ”

When Ma Lijun heard this, he hurriedly said: "Please make it clear to Mr. Lian." ”

"Hardness!"

Liu Juntao broke the cement block again and said: "The hardness of this soil cement is not enough, and the workshop must find a way to solve it as soon as possible." My standard is: rock solid! ”

Ma Lijun nodded heavily when he heard this, and said, "Don't worry, I will do it immediately!" ”

Ten days later, Liu Juntao received an urgent report from Ma Lijun again, and the hardness of soil cement had been improved.

Liu Juntao immediately rushed to the Yushan cement workshop, only to see a piece of solidified cement on the open space, a craftsman in front of Liu Juntao, directly with a sledgehammer to hit, after the "bang" sound, the cement block just dropped a little debris, the whole is still intact!

Seeing this, the surrounding craftsmen immediately cheered, and Ma Lijun's face was also full of pride.

Liu Juntao was also very happy to see this, although the improved soil cement still cannot be compared with the concrete of later generations, but at this time the Ming Dynasty is already a miracle, which can fully meet the construction of Yushan Town.

"Good!"

Liu Juntao said loudly in front of everyone: "All the craftsmen who participated in the research and development of soil cement will be rewarded with ten taels of silver each, and the monthly salary will rise by one percent!" Steward Ma Lijun rewarded 20 taels of silver, and his monthly salary rose by 20%! ”

As soon as the words fell, the crowd cheered again.

After that, Liu Juntao said to Ma Lijun: "Immediately organize people to build a model house at the new site of Yushan Town, and the construction method will be according to the method I gave you before, and it will be watered with cement!" ”

Ma Lijun nodded excitedly, knowing in his heart that the house he was going to organize and build would be the first cement house in Daming, which was a great opportunity to become famous!

On the same day, Ma Lijun rushed to the new site demarcated by Yushan Town with his manpower, and started working day and night.

Five days later, a very simple house was erected on the new site of Yushan Town, and the whole house was built with earth-made cement, which was very strong, like a stone house.

Tang Yu and all the craftsmen in the workshop were amazed.

Liu Juntao, who rushed to hear the news, was also very satisfied, and immediately ordered the Yushan Cement Workshop to start producing Huangming brand cement at full strength, do a good job in the reserve of cement, and prepare to fully build Yushan Town in the spring of the next year!

Tang Yu also said that he would immediately organize people to allocate money and grain, and he would ensure the smooth construction of the new site in Yushan Town.

When Liu Juntao rushed back to Yushan Town, he happened to see Zhang Baigui blocking his door, so he asked, "Is there something wrong with Master Zhang?" Come in and say. ”

I saw Zhang Baigui smile and said, "Haha, I have a great thing to tell Jun Tao about you." ”

"Oh? What's a good thing? ”

Zhang Baigui said in a deep voice: "In the past few months, the War Bureau has been working day and night, and now it has reserved orthodox nine-year-old bird guns."
