By March, the cement kiln had been completed.
The cement plant workers also prepared limestone powder, clay powder, and other materials.
Even charcoal, blowers, and other supplies have been prepared.
"Mix the ingredients!"
Dong Haibao directed the workers to mix the limestone powder and clay powder together thoroughly according to the specified ratio.
The prepared raw cement materials were also sent into the cement kiln.
After a cement kiln is full, the workers also transport charcoal into the kiln.
Light the fire and seal the kiln.
The blower next to it was also blowing air into the cement kiln.
This is the first kiln in Dongning City. To be on the safe side, we will wait until this kiln is successful before starting large-scale production.
Standing to the side, He Tongyuan frowned and asked, "Your Highness, is the cement you mentioned really that powerful? Can it even glue stones together?"
That's what the book says. As for the results, we'll find out soon enough.
Li Xin smiled and pushed everything into the book.
Whether it's gunpowder, soap, or cement, Li Xin learned about their origins from books.
This explanation has also reduced the number of doubts.
After the cement kiln was sealed, it was not reopened until noon the next day.
After a whole night of calcination, it must have been successful.
When we arrived at the cement kiln, workers had already opened the kiln door and gone inside.
Before long, a handcart loaded with gray clinker came out.
"This is... cement?"
Liu Jingxuan narrowed his eyes and asked doubtfully, "This cement, can it really be used to build houses, bridges, roads, and city walls?"
Liu Jingxuan, a well-read scholar, had never seen any record of cement in any books.
Therefore, Liu Jingxuan was somewhat skeptical.
"Yes, it's very useful!"
Li Xin smiled and walked to the handcart.
At this point, the workers nearby added the prepared plaster powder according to the specified ratio and mixed it thoroughly.
After mixing, cement is made.
"Dong Haibao, test the effect!"
Li Xin gave the order.
"yes!"
Dong Haibao nodded, then took sand from the side, mixed it with cement, added water, and began stirring.
After mixing the cement thoroughly, several bricklayers began to build the wall.
Before long, a low wall, about half a person's height, was built.
Looking at the soft cement on the ground, Liu Jingxuan still couldn't quite believe it was that powerful.
Although I had my doubts, I would wait until the experiment was completed to find out how effective the cement was.
Another day passed, and the cement wall had dried.
Li Xin kicked it directly, but the cement wall remained firmly standing, unmoved.
Liu Jingxuan's eyes widened in shock.
Surprisingly, such a small amount of cement could hold the bricks together so firmly.
It's almost as good as rammed earth!
The guards nearby stepped forward and kicked the concrete wall several times, finally knocking it down.
However, the bricks were still stuck together.
"The effect of this cement is truly unbelievable!"
Liu Jingxuan realized the importance of cement and exclaimed in surprise, "With cement, building the city wall will be much easier for us!"
This cement is simple to make, and the materials can be found everywhere.
"If we have a few years, and all the prefectures and counties in Dongning Province have their walls replaced with cement, let's see how those grassland bandits will be able to cause trouble here!"
"Hahaha……"
Li Xin shrugged and said, "The cement wall is indeed sturdy, but I'm afraid it won't be enough to stop the grassland bandits with just this cement wall!"
As the saying goes, the strongest fortresses are often breached from within.
With this cement, it's not just for building city walls.
Most importantly, we need to build houses so that all the people in the city can live in good houses.
Only when the people are united can a fortified city not crumble from within.
"If only I could have ten thousand spacious houses, to shelter all the poor and needy, and make them all smile with joy!"
Liu Jingxuan was stunned; he really didn't expect His Highness to say such a thing.
If only I had ten thousand mansions, I could shelter all the poor and make them smile!
This line of poetry is extremely apt!
Your Highness is truly benevolent and loves your people!
For a moment, even Liu Jingxuan was somewhat impressed.
...
After the first batch of cement was successfully produced, Li Xin instructed Dong Haibao to speed up the production pace.
The cement plant's production quickly got back on track.
Four or five cement kilns took turns firing.
Grind into powder, form raw materials into balls, and fire in a kiln...
Each step has a designated person in charge.
One cement kiln after another, producing cement incessantly.
Cement clinker was also bagged and neatly stacked along the city wall.
With more and more cement products being produced, it's time to put the repair of the city wall on the agenda.
Although winter has arrived, the frozen ground has not yet completely thawed, so agricultural reclamation has not yet been put on the agenda.
The idle people also all came to the city wall construction project.
Some locals also quarried long stone slabs in the nearby mountains and forests and transported them to the city wall.
On the other side of Dongning City, several brick kilns were specially built to fire blue bricks.
All the work is in preparation for the repair of the city wall.
Even Li Xin was not idle.
In the past few days, accompanied by Wei Jun, He Chaojun, Liu Jingxuan and others, Li Xin has been inspecting the northern part of Dongning City.
Li Xin also had other plans for Dongning City.
After all, Dongning City is too small now.
