There are two reasons why those lands cannot be used at present. First, the hyphae of Procyondra repens have a very strong invasive ability.
They choose to absorb energy from any carbon-based life form they sense, a fact that deters all other living beings.
Secondly, the fruiting bodies of *Prorocentrum spp.* release large amounts of carbon dioxide, which is heavier than air and will settle on the ground.
This is the first fatal factor; apart from anaerobic bacteria, no animal can survive in this environment.
The problem of fruiting bodies can be solved, however, as those *Protozoa* grow extremely fast. This means their xylem density is not very high, making them easier to cut down than ordinary trees.
The process is similar to felling a banana tree; it's basically something you can cut down in a few strokes. The only difference is that their underground mycelium will sprout new fruiting bodies.
At this point, we need to find a way to suppress the ground sub-entities and prevent them from growing upwards.
At this moment, I do have a method in my mind that could have done this in the past, which is the method used in real estate development.
Whether in desert regions or desolate mountains and wilderness, wherever this team appears, all terrains must circumvent them.
It can move mountains and fill seas, or pave roads and build bridges.
No matter how dense the forest or how troublesome the shrubs and thorns, once that high-grade concrete is poured on top, even the most resilient plants will have to give up.
Moreover, concrete is not as loose as soil, so even if weeds and saplings were to be broken off, they would not be able to grow.
I think that as long as a layer of concrete is poured on the leveled land, the fruiting bodies of those Protoplastia will naturally be unable to grow and cause trouble.
Without the threat of fruiting bodies, and since concrete is inorganic, mycelia are not interested in these nutrients, so dried concrete floors are safe to use.
We need to conduct an experiment first. As for the cement used to make concrete, we don't lack the raw materials for production here.
Cement is mainly made from raw materials such as limestone, clay, iron ore and coal.
First, these raw materials are mixed in proportion and then ground into raw material.
Then, the raw materials are placed in a cement kiln and calcined at a temperature of around 1450 degrees Celsius. This process causes complex physical and chemical changes in the raw materials.
The product after calcination is called clinker, and its main components are tricalcium silicate, dicalcium silicate, tricalcium aluminate, etc.
Finally, the clinker is ground together with gypsum and other auxiliary materials to obtain cement.
To be on the safe side, we need to use high-grade cement; this is for long-term planning.
Compared with ordinary grade cement, high-grade cement mainly consists of tricalcium silicate, dicalcium silicate, tricalcium aluminate, and tetracalcium aluminoferrite.
However, high-grade cement contains a relatively high content of tricalcium silicate (C).
Tricalcium silicate hydrates rapidly, which allows cement to grow quickly in its early stages, enabling it to reach the required strength for a higher grade in a shorter period of time.
At the same time, high-grade cement has stricter quality control over raw materials during the production process, and contains fewer impurities, which also helps to improve the performance of the cement.
There are several methods that can be used to increase the tricalcium silicate content in high-grade cement:
Firstly, the control of raw materials
- Choose high-quality limestone: Limestone is the main source of calcium in tricalcium silicate. Selecting limestone with high calcium carbonate content and few impurities provides a sufficient calcium source for the formation of more tricalcium silicate. For example, calcite-type limestone has a high calcium carbonate content and is very suitable as a raw material.
- Carefully selected clay raw materials: Clay is an important source of silicon, so it is important to choose clay with an appropriate silica content. For example, kaolin has a high silica content, which helps in the formation of tricalcium silicate.
Speaking of kaolin, I discovered several mineral deposits where large quantities of kaolin can be mined.
Limestone is available in many regions, so you can bring more to select high-quality limestone for use.
Secondly, adjust the production process.
- Optimize raw material ratio: Precisely adjust the proportions of raw materials such as limestone, clay, and iron ore. Appropriately increasing the proportion of limestone can increase the calcium content, which is beneficial to the formation of tricalcium silicate. At the same time, strictly control the particle size of raw materials; fine grinding of raw materials can ensure more complete reaction during calcination.
- Controlling calcination temperature and time: The formation of tricalcium silicate requires suitable calcination temperature and time. Generally, a temperature of around 1450°C is suitable, and it is essential to ensure that the material has sufficient residence time in the high-temperature zone to allow the reaction for the formation of tricalcium silicate to proceed fully.
In terms of high-temperature conditions, the double-inlet siphon furnace that I previously used for iron ore refining can easily reach the temperature required for calcination.
As for grinding machines for grinding stones, we can use the power of water flow to make a water-powered grinding machine.
My idea is to make a huge millstone out of basalt and then use water flow to power the millstone to grind the raw stone.
As long as we get this real estate business going, we won't have to worry about those Haru people having nothing to do or nowhere to put their energy to work.
If there's too much manpower, then we should increase the manpower entirely. The limestone being mined needs to be crushed with hammers, and the iron ore also needs to be crushed with hammers.
Kaolin and coal mines require picks and shovels to dig, and each task requires a lot of effort.
If all else fails, there's the grinding work, where raw materials are continuously added to the giant stone mill for grinding, a task that almost never stops.
This is just the initial cement production. Later, we may need to produce aggregates for concrete, which would be a huge undertaking and might require quarrying.
The work of smashing rocks would probably make them question the meaning of life.
If we want to solve the housing problem in the short term, we may need to build more apartment buildings.
Naturally, materials such as steel bars would be needed. Once these tasks were planned, all the laid-off workers in the Haru army could instantly start working.
Having figured all this out, I felt incredibly excited. It was like solving a major problem of the century. As long as everyone has work, a place to live, and food to eat, there won't be so many social problems.
That very day, I summoned the leaders of the Mira and Asada tribes, who were equally troubled by this problem.
After hearing my brilliant description, the two leaders exchanged bewildered glances. I must say, both leaders agreed that my thought process was truly unique, always managing to come up with something truly eye-opening.
The leaders believed that this big family really couldn't do without me as the backbone; without me, the family would fall apart sooner or later.
