Why are the bricks used to build the house so red? The old blood of Taishang Laojun dyed them red.

If Zhu Guoqiang knew that Red Brick had become like this in the eyes of everyone, he would probably be so angry that he would spit out a few mouthfuls of old blood. His original intention was to combat "superstition", but in the end, he further confirmed that he was a "fire"

Lord Dezhen descended to earth.

I have to say that this is a bit... a trick of fate.

However, Zhu Guoqiang has not been leisurely to interfere with these matters recently. After all, there are still many things that need to be dealt with by him at the moment.

Just like in the past few days, he has been focusing on the "research and development" of cement. In fact, if possible, he would be more willing to purchase a complete set of vertical kiln small cement production equipment, but even this kind of "backward" "small equipment"

"It also requires a large amount of equipment. Not only is the technical condition beyond the scope of what craftsmen can operate, but it not only requires technicians to operate, but also requires the use of a large amount of raw materials, and the raw material production capacity limits the possibility of industrial production.

In fact, the raw materials needed for cement, such as clay, lime, and gypsum, were all found near the royal tombs. However, considering technical issues and other issues, after careful consideration, Zhu Guoqiang decided not to consider industrial production for the time being, but to make do with simplicity.

Burning "earth cement" to meet the current construction needs, in fact, the demand for cement on the construction site was created by Zhu Guoqiang himself - because the royal tomb is built on the mountain, there are a lot of stones nearby that can be used, compared to bricks

The clad city wall and the stone clad city wall are not only stronger, but also cheaper, but they require cement masonry with irregular stones.

It is obviously unrealistic to just rely on cement shipped from another world. After hundreds of tons of cement were shipped, Zhu Guoqiang decided to produce cement on site. Without considering industrial cement production, the only option was "earth cement"

In the decades after liberation, many rural areas in the country have made it. It has been widely used not only in rural buildings, but also in many small water conservancy projects. The production of "earth cement" does not require complicated processes.

The equipment flow and process are also extremely simple, and there are several simple processes.

The simplest is to crush the fired bricks or pottery into fine pieces, and then put the lime and clay in a brick kiln in proportion to be calcined. The production process of this "earth cement" is extremely simple, and it does not even require Zhu Guoqiang to print "

"Technical Manual", just need to explain it, and the old craftsmen in the brick kiln will know how to make it. Its performance is roughly equivalent to that of cement around No. 300, although according to the views of later generations, such cement is not suitable for engineering purposes. But

This kind of cement was not only widely used in the infrastructure construction of the southwest rear area during the Anti-Japanese War, but also was widely used in the construction of small and medium-sized projects in the 1950s and 1970s, and even in the construction of small hydropower stations.

Of course, Zhu Guoqiang's entire understanding of "earth cement" was obtained through searching the information on the Internet. In articles such as "Dagan Earth Cement" in the 1950s, its production process was briefly introduced.

He just solved the formula problem, but it's hard to say whether it can be used. So, he has been staying in the kiln for the past few days, asking people to take a batch of red bricks fired in the brickyard for experiments. Then the craftsmen will use it.

The hammer broke the bricks into small pieces, and the grinding work was originally planned to be done by stone grinding, but the efficiency of stone grinding was unbearably low. After working for a long time, only less than a hundred kilograms of raw materials were produced.

After the finely ground raw materials were sifted, Zhu Guoqiang mixed the powder thoroughly, then added water and stirred it. Under the watchful eyes of the craftsmen, the cement was used to build a stone wall.

"Is this okay?"

Old Dingtou and others were all dumbfounded when they saw the rubble on the irregular sides being easily put together. When mixing the cement, he even touched the Hui Bu Yo cement.

"It's hot!"

This discovery made him excited, and he subconsciously thought - this must be something made by Zhenjun Huode. Otherwise, how could the cement become hot if it is mixed with water?

For everyone like Lao Dingtou, who had already stubbornly believed that the Crown Prince was the True Monarch of Huode, they even forgot the most basic common sense - lime will heat up when it meets water.

After the cement for building the wall had dried and it was proved that this "earth cement" could be used completely. Seeing that the craftsmen needed to do heavy physical work of breaking bricks with hammers, Old Dingtou asked the prince.

"Your Majesty, I have an idea, but I don't know whether to express it or not."

"What can't you say? What do you think?"

Zhu Guoqiang asked with a smile.

"Your Majesty, I think it's too hard to break bricks with a hammer. The village where I lived in the past made a living by making wood powder for mosquito smoke. They used a hammer to smash the wood powder, so I thought,

Can I use a water hammer to smash the powder? There is a river two miles away, and there is a mill in the past. Since we can carry the mill, it shouldn't be difficult to bring a water hammer."

Shuizui!

Zhu Guoqiang is no stranger to water hammers. my country invented the water hammer in the Han Dynasty. In principle, there is no difference from the European water-powered forging hammer. However, the Europeans used water-powered hammers to create plate armor, which doubled the efficiency of metal forging. While reducing costs, China still uses water hammers to grind rice up and down and process wood powder and pulp, but it is not used in metal processing.

"Then let's try."

What needs to be tried there? The water bucket itself does not have any technical difficulty. For the skilled carpenters in the palace, making the water bucket is a piece of cake. In order to improve efficiency, Zhu Guoqiang specially brought several ball bearings from another world.

On the waterwheel.

But in just a few days, a drum-type water hammer with 6 hammer heads was installed by the river. The water hammer can not only process cement day and night, but can also be used to forge iron.

"You guys try it first, use this forging hammer to hammer the tools needed on the construction site, first simplify and then complex, try slowly..."

When Zhu Guoqiang personally guided the blacksmith on the construction site to forge tools with a water-powered hammer, even though the iron rod he forged was shapeless, when he saw the red iron block being formed by the forging of the water-powered hammer, those who had been hammering for half a life were

The blacksmiths were all dumbfounded.

"Well, from now on, we don't have to use people to hammer the iron?"

While the blacksmiths were excitedly trying out the water-powered hammer made by Shi Ziye, two strange visitors came to the "workshop" at some point. They watched the hammer head of the water hammer forging iron blocks, and splashed out from time to time.

Sparks, Chen Zhihuan murmured.

"Here, this water hammer for pounding rice can actually be used to make iron. I, why didn't I expect... This water hammer can be used to make iron day and night. Isn't it a hammer that can do a hundred things..."

Zhu Guoqiang, who was feeling proud, said casually when he heard the voice behind him.
