It is said that there is strength in numbers. Under the hard work of 10,000 enthusiastic Habayashi Guards, even without any 'modern' machinery and relying only on their hands, the work of leveling the site only took five days.

At this time, the first batch of building materials purchased by Li Chengming had also been shipped.

Then, under the command of the craftsmen of the Camp Repair Department, a group of Yulin Guards officers officially began to prepare for laying the foundation.

"Masters, since the three combined soils have been prepared, why are they piled up and not used?"

Seeing that a large amount of "concrete" mixed with lime, loess and river sand was piled up and not used, Wang Bing couldn't help but look puzzled.

"I would like to inform the Marquis that this Sanhe soil cannot be used now. It must be matured before it can be used."

Seeing Wang Bing's confused look, several craftsmen quickly stepped forward to explain to him.

"Mature?"

Wang Bing, who didn't know much about ancient building materials, became even more confused after hearing this 'professional' terminology.

"Master Marquis, the more times this Sanhe soil is matured and refined, the better its effect will be. If it is matured and refined for more than nine times, the foundation built with it or the site after being compacted and leveled will not only be extremely solid,

It is also flood-proof, waterproof and immersion-proof, making it absolutely indestructible!”

Facing a layman like Wang Bing, several craftsmen immediately explained to him the refining process of this triple soil.

It turns out that the triple soil mixed with lime, loess and river sand needs to be continuously smelted and turned, and it also needs to be piled and parked to allow it to blend and age better. After the fusion and aging for a period of time, it will be turned again.

Refining and beating until it can be kneaded into a ball and kneaded into powder will be considered successful.

"So, the refining and maturation of this Sanhe soil alone will take more than ten days?"

After listening to these craftsmen's introduction to the refining of Sanhe soil, Wang Bing couldn't help but frown.

"Back to Lord Marquis, according to the current weather, it will take about three or four days to mature and refine once. It can only be practiced three times in more than ten days. If you want to refine more than nine times, it will probably take a month."

After thinking for a moment, these craftsmen gave an approximate time required for refining Sanhe Tu.

"A month? Can we refine and prepare all the required Sanhe soil at once?"

After knowing the time required to refine the Nine Refining Triple Soils, Wang Bing silently calculated it in his mind and felt that if all the Triple Soils could be prepared at one time, even if it took a longer time, it would not be unacceptable. After all, the effect was in

It's laid out there.

"Well, Lord Marquis, if this triple soil is left for too long, the effect will be..." Obviously, although this triple soil is very effective, it cannot be made in advance and stored for a long time like the cement of later generations.

"Although this thing is more effective than cement, it is too time-consuming!"

Knowing that Sanhe soil could not be prepared in advance and stored for a long time, Wang Bing couldn't help but feel depressed.

"Well, the foundations of these houses still use Sanhe soil, but the square and the ground are no longer needed. I will think of other ways."

In the end, in line with the principle of durability, Wang Bing finally decided to still use the Nine-Refined Sanhe soil for the foundations of these houses in the military academy. However, he directly rejected the square and the academy ground, which used the largest amount of Sanhe soil.

"Master Hou, you have paved the ground with bricks and stones, but it still needs to be compacted and hardened with Sanhe soil! Otherwise..."

Seeing that Wang Bing, a 'layman', actually wanted to interfere indiscriminately, these craftsmen couldn't help but remind him one after another.

"Who said you can't harden the ground without using Sanhe soil? Do you want to make a bet with me? I will even save the bricks and stones for paving the floor this time, hahahaha!"

…

"General, can't we just buy this lime directly? Why do we have to bake it ourselves?"

On this day, in front of a small temporarily dug earthen kiln, Wang Bing directed everyone to put the crushed limestone mixed with clay into the kiln to prepare for firing. Not to mention the Yulin Guards, even those

The craftsmen of the Camping and Restoration Department also looked confused and puzzled.

"Haha, you will know if it is burnt lime after it is burned!"

Without explaining to these people, Wang Bing directly had the kiln closed and started to be fired.

A few days later, when the temperature of the kiln dropped, Wang Bing had the clay mixed with it, and then the limestone calcined at high temperatures was ground together with the iron-making slag he asked Li Chengming to transport back.

"It should be almost done!"

After feeling the delicate touch between his fingers, Wang Bing nodded with satisfaction.

Then, with everyone watching, Wang Bing immediately asked someone to use the freshly ground gray powder, mix it with some sand, gravel and water, and quickly prepare a pile of low-profile concrete.

"Is this it?"

Looking at the pile of low-profile concrete that Wang Bing had laid directly on the ground, the craftsmen of the camp and repair department couldn't help but look at Wang Bing with doubts on their faces and asked.

"Well, it's almost done. In a day or two, it should be ready when they are completely dry!"

Looking at the simple cement that he had spent several days making in front of him, Wang Bing himself was not very sure. After all, this was just a simple cement production method that later generations saw on the Internet. The specific effect still had to be determined.

Look at the final product.

…

"General, it's done, it's done, it's really done!"

Early the next morning, while Wang Bing was still sleeping soundly in the tent, the distinctive loud voices of Shuerhaqi and Manhai could be heard in his ears.

"What's the matter? Why are you whirring so hard so early in the morning?"

After yawning, Wang Bing couldn't help but asked with a puzzled look.

"General, the ground you paved yesterday has really hardened and turned into a hard and big stone!"

Facing Wang Bing's doubts, Shuerhaqi couldn't help but look at the sleepy Wang Bing with excitement and admiration and shouted.

"Oh? Doing it so fast? Let's go and have a look!"

As soon as Wang Bing heard that the soil and cement project was successful, he immediately became interested and climbed out of the big tent where he lived in a few steps.

…

"Young Master Hou is so thoughtful, I admire you so much! But we lost this bet!"

As soon as they arrived at the place where the concrete was laid the day before, all the craftsmen from the camp and repair department excitedly surrendered to Wang Bing.

"It's a pity that I forgot to place a bet with you yesterday, otherwise I would have won a lot today, hahahaha!"

Wang Bing couldn't help but be overjoyed when he saw that his soil and cement project was really successful.

"Master Marquis, with this thing, whether it is building cities and buildings or building bridges and paving roads, it will be much faster than before!"

After the subsequent smashing and testing, the craftsmen of the maintenance department were full of praise for the performance of the soil cement.

"Haha, this thing is only better because of its high speed and low cost. If it is really used to build cities, build houses and build roads, it will only last for a few decades at most, and then it will slowly weather and become brittle!

"

Wang Bing knows much better than these craftsmen about the urine properties of cement. So even if his crude soil cement is successful, he still has no intention of using it to replace the three-component soil to lay the foundation. He just plans to use this thing

Just paving the ground and building roads.

But even if he was unwilling to use the soil and cement to build the military academy's houses, he still couldn't stop the enthusiasm of the craftsmen.

Therefore, during this period of refining Sanhe soil, the number of cement kilns in Nanhaizi increased rapidly. As a result, the ground was hardened before even the houses were built.
Chapter completed!
