Such layers of stone walls, simple and rough, very ugly, but not yet finished.

Mortar patching until all the stones are wrapped in concrete, and this is the end.

Although it was still ugly and rough, everyone present clearly saw the huge advantages of this concrete wall!

The workers in charge of the operation are skilled, and novices must not be able to compare, but this thing doesn't look very technical!

But anyone with a clever brain, I'm afraid that it will be able to learn in half a day!

The most important thing is that there are no too high requirements for the filled stones, and it is not a problem to have strange shapes and sizes!

It's okay if the patchwork is not smooth, just fill the concrete joint!

The time it took to complete the whole process was, in the eyes of everyone, not enough to dig an eye out of a normal stone!

"This is the kind of cement that Zhao Dongzhu took out before?"

"After this mortar solidifies, it will be so hard!"

"This is an artifact for building houses and repairing cities and dams!"

Officials and big families were arguing around the newly built stone wall, and their eyes were full of excitement!

This is exactly the effect that Zhao Hengyi wants, for this, he specially asked the workers to use unpolished and repaired irregular stone walls, if only red bricks or strips of stone are used, it will not show the advantages of cement in building embankments!

Repair the embankment, it is good to be strong, and beauty is secondary!

In the eyes of the gentry or cultured people, the industrial products that will surely change the appearance of the whole world are not a matter of being rough or even ugly, and the strong power of cement will make everyone make the most honest choice with their bodies!

Even if all the stones were covered by mortar, the stone wall was still rough, and the wall was undulating, not regular, but in any case, the stone wall was indeed built.

All the officials and big families present only had to wait silently, waiting for the cement that was the most critical to build the stone wall to slowly solidify.

Zhao Hengyi took advantage of this time to popularize science to everyone, an hour after the stone wall is built, it is the initial setting of cement, and after 12 hours, it is the final setting.

The next few hours are the beginning of hardening, and the process by which the concrete mixed with cement really becomes solid.

In the process of hardening, concrete needs to be constantly sprinkled and cured, even in modern society, technology throws off countless streets in Dayan Kingdom, and this process is indispensable when using concrete.

Even in the north, because the weather is too dry, straw mats need to be spread on the slowly hardening concrete before sprinkling water to maintain the moisture for a longer time.

Zhao Hengyi's words made the eyes of officials and big households shine, this new mortar called cement actually likes water!

If all this is true, then this thing is simply for the purpose of building a dam!

In the desolate and dilapidated temple on weekdays, a group of arrogant officials and gentry kept looking around a rough and ugly stone wall, as if they wanted to see flowers from the stone wall.

Zhao Hengyi explained everything clearly, and then took people to turn their heads and get into the house that was barely sheltered from the wind and rain, braved the rain to hurry, and went to the river embankment to accompany Liu Xianling to patrol the embankment, and just covered up the use of cement, Zhao Dongjia, who had not been idle in the village, was tired and needed to sleep well.

As for that, there is also the prefectural magistrate of the prefecture outside...... The proprietor is still a man from Cangwu County, a proper lord, and he doesn't care about a county order!

Zhao Hengyi can sleep as the owner, but the skilled workers who are responsible for transporting cement and building walls outside can't, and several people are all pulled by officials and big families to ask questions.

Before coming, the village had already explained, and after coming, the owner repeatedly told that the workers and a group of old foxes could not be compared, but it was related to the effect and usage of cement, and they could talk freely.

But if someone tries to knock on other things in Elm Bay, the workers will instantly become dumb and silent.

In the end, at the suggestion of Liu Rui, the county magistrate, everyone dispersed and rested, next to the concrete stone wall, only one or two people were left to watch.

The next morning, everyone gathered around the stone wall early, and they were shocked to find that the concrete ...... It's really getting harder!

Someone tried to buckle their fingernails, but only to scrape off some powder, and their own nails were broken!

It can't be buckled at all!

Officials and big households are ecstatic, with such an artifact for building embankments, it will be difficult for the river embankment in Dangyang County to break this year!

Especially the time for this new mortar to solidify and harden is too fast!

The workers from Elm Bay really watered the stone wall, which made the people present look so amazed that they were a little nervous after watering, and their hands trembled slightly......

Not all of the people present knew anything about the building, and there were even many knowledgeable people in the crowd, especially among the officials.

A county government can actually be regarded as a small abbreviated version of the imperial court, but any function that ordinary people can come up with is enough to coincide with the configuration of the imperial court.

As for what ordinary people don't know...... There is no need for such an institution in a small county town.

The miscellaneous officials who supervise and repair all kinds of buildings and are responsible for all kinds of civil works are obviously knowledgeable professionals, and there have been secret contacts from large households before, so that the miscellaneous officials can secretly evaluate the new mortar.

At this time, when the stone wall was drenched with water, the prefectural magistrate also looked at the miscellaneous officials who could understand the business.

In that case, it's time to do it.

The officer stepped forward and gently tapped the wet stone wall with a small hammer he carried with him, and found that the stone wall was still strong!

As Zhao Dongjia said yesterday, this cement likes water!

You know, if the wall is made of triple soil, if it is stained with water in just one night, it will inevitably become soft, and maybe the wall will collapse!

It's amazing how it solidifies and hardens overnight!

Even the glutinous rice mortar that makes the Suzhou Mansion of the rich world make a joke often needs to stand for about ten days before it solidifies and hardens, and it can really play the great name of glutinous rice mortar, and it can really resist the beating of the outside world, and it even takes a year later!

Whether it is Sanhe soil or glutinous rice mortar, there is no comparison with the cement taken out by Zhao Dongzhu at all!

"Ladies and gentlemen, this cement is really an artifact for flood resistance and dam repair!"

Liu Rui, who had been faintly worried, so Liu Rui, the county commander who kept a low profile, finally smiled, "With the artifact, let's start talking about it now, how to build the river embankment in our Dangyang County!"

Ladies and gentlemen, you all have clansmen and land in Dangyang County, since this official has promised to work instead of endowment...... Don't you take this opportunity to completely build the embankment of the Liuhe River into a permanent golden soup that will not have the risk of bursting for a hundred years and thousands of years? ”
