At the end of June 959, artificially fired cement appeared on the earth for the first time, and the starting point was very high, establishing a very solid theoretical foundation, although it was still relatively simple.

According to the history of Zhao Yuan, cement was first fired in 1796, a brown cement made of marl by the Englishman J. Parker, if correct, Zhao Yuan advanced the appearance of cement by more than 800 years.

In a remote mountain village in Shudi, at the foot of Baishi Mountain, a kiln with a very ugly appearance is calcining cement, and the smoke rising from the big chimney makes this era drift away.

At this time, nearly four months have passed since Zhao Yuan brought the refugees from Danling County to Gray Yuan Town.

Looking back on the problems and hardships encountered in the past four months, Zhao Yuan not only felt a lot of feelings. In the past four months, Zhao Yuan didn't know how many problems he had solved with everyone, and even Shao Meng, who was busy with Zhao Yuan, and a few workers had a clear understanding of all aspects of cement production.

The selection of refractory materials, the development of rotary furnaces, the manufacture of hydraulic crushing machinery, the development of hydraulic mixers...... One by one, the workers and even Wan Yunjun and others who came to Gray Plains Town to check the situation were stunned, and under the leadership of Zhao Yuan, the machines magically appeared in this world.

In addition to these inventions, other things such as clay, iron ore, and road construction are considered minor problems.

In the past four months, Zhao Yuan has not only devoted himself to the construction of the cement workshop, but also solved a lot of other things.

The cement factory guard team has been formed, and Zhao Yuan handed over the training of the factory guard team to Miao Shijie to be responsible, but he just mentioned to him some concepts of army training in later generations. The team has expanded to 50 members, and after the formation of the team and the training in the following three months, the team can be said to have achieved the ban and is well-trained.

"Owner, the cement quality of this furnace seems to be better, let's experiment it right away." Yang Nian, who has been involved in the construction of the cement workshop with Zhao Yuan, said.

"It can definitely be finalized, this furnace owner has reached the limit of the current situation, and the main sealing problem is very difficult to solve." Another worker, Liu He, said.

"I think so too, I'm going to open the furnace right away, let's give it a try."

After a few months of edification, everyone's tone of speech is very close to Zhao Yuan, and some professional words can be said from everyone's mouth.

The trial production of cement has been carried out many times, and today it has finally been finalized, which is almost a full year since Zhao Yuan arrived in this era.

"The old rule is to measure the bulk density, fineness, setting time and strength of cement." Zhao Yuan said to everyone with a smile.

Combined with the situation of this era, Zhao Yuan set up a grading standard for cement according to the cement number of later generations, which was divided into four grades according to the strength of cement, and the mildness of the previous furnace of cement has reached the grade C and grade 3 of the cement grading standard established by Zhao Yuan.

"If this batch of cement meets the standard, we will start to use cement to build a house for our cement workshop first, and everyone has worked hard in the past few months." Zhao Yuan sighed.

In the past few months, it has been hard work, and every worker involved in all aspects of cement production has basically tightened a string in his head, especially after several months, the production of cement has been unsuccessful.

More than 1,000 people rely on the cement workshop to eat during this time, and if the cement workshop is not successful, everyone does not know what fate will be faced.

"Owner, the cement has been produced, let's find a way to sell it first."

"Yes, the owner has invested a lot of money in it, and there is no problem with where we live now."

The initial investment in the cement workshop has already been spent, but fortunately, when Zhao Yuan signed the cement workshop investment agreement with Zhang Xucong and a few others, he considered that the investment might be exceeded, and the follow-up investment was injected into it according to everyone's share.

In the past few months, the soap workshops in the county have already completed the expansion, and workshops in other cities have been established one after another, and they have initially generated profits.

"The cement workshop has now been built almost, and it will depend on you in the future, according to the cement workshop procedures we formulated, the current cement kiln still has many deficiencies, and we should pay attention to the continuous improvement and upgrading of the cement kiln in the future production process." Zhao Yuan said with a smile.

With some simple machines that Zhao Yuan has led everyone to make in the past few months, under the White Stone Mountain, it always looks like it is in full swing. Zhao Yuan's concept of taking the factory as his home makes everyone very recognized by the cement workshop, and like their own children, everyone makes efforts to take care of the development of the cement workshop.

Thanks to the process designed by Zhao Yuan, after the official production, the cement workshop can produce a large amount of cement every day.

"Don't worry, boss, we've learned a lot from you in the past few months, and we'll be able to solve all the general problems." Yang Nian said with a smile.

"Okay, then it's time for me to think about how to sell the cement we produce." Zhao Yuan nodded and said with a smile.

Walking out of the cement workshop, Zhao Yuan inexplicably has a feeling that things are wrong, in the past few months, Zhao Yuan has almost soaked in the cement workshop to solve various problems, through one technical difficulty, the number of times he has gone home is only a handful, and now the cement workshop has been on the right track, it is time to spend more time with his family.

"Uncle Xiang, you're here to sell vegetables again?" Let everyone be busy with their own things, Zhao Yuan walked out of the cement workshop production area, and saw Lao Zhutian leading the villagers to move baskets of vegetables to the cement workshop canteen.

"It's Boss Xiao Zhao, I'll take everyone to sell vegetables." Wang Xiang said with a smile.

"This dish is so fresh, thanks to everyone's support during this time." Zhao Yuan said with a smile.

"We also want to thank you for not only building the road from our village to the outside so well, but also allowing people from our village to work in your workshop to earn money." Wang Xiang smiled.

"It's all a mutually beneficial thing, like uncle, it will only get better and better in the future."

"Good, good."

……

Zhao Yuan said hello to the villagers of Lao Zhutian, and continued to walk outside, as the small supermarket in the market entered the formal, the guys were completely familiar with the small supermarket, and now only Zan Zhao was left to continue to do the security work of the small supermarket, Zhu Mian and Xu Xiang had returned to Zhao Yuan's side.

When Zhao Yuan was busy in the cement workshop, Shao Meng and the four of them trained with the escort team, and now the temperament of the soldiers on several people began to slowly appear.

"Lord (Lord)."

On the road outside the workshop, Shao Meng and the guards saluted Zhao Yuan.

"Hello, today's training is done?"

"Back to my lord, today's daily training has been completed."

"Okay, you guys assign patrols." Zhao Yuan nodded and said to everyone.

"Shao Meng, the four of you will go home with me."

The strength test of the cement will take some time, and Zhao Yuan can go home to see it.

During this time, Meng Ying started the purchase of wild mushrooms this year, and she was also busy at home. Originally, Zhao Yuan wanted Zhaojiazhuang's uncles and brothers to process the mushrooms themselves and then sell them, but this year they still pulled Meng Ying to take the lead.
