Building materials - part 2

During this day I dedicate myself to convert the solid rocks product of the fusion of powder mixture. This powder is cement, with this we could make the necessary mortar to build the supports of the water wheel.

On the other hand, they were still making bricks, but before they finished with all the raw materials brought by the expedition group, I made sure to divide the amount, one for the bricks and the other for the construction material of the blast furnaces, the refractory bricks.

This type of brick is special, since it holds up very well the high temperatures and also conserves these high temperatures. They are the right material for blast furnaces.

When I was assured that cement manufacturing was going well without the need for intervention, I decided to start with the production of refractory bricks.

The creation of these bricks is the same, the only difference is the mixture used. Together with several people, we started preparing the mix. To make these refractory bricks we need: 40% clay, 30% kaolin, 30% calcined clay and finally sawdust.

Kaolin is a special variety of white clay, this has several properties that help thermal resistance. And as for the calcined clay this is obtained from the remains of clay objects that we started doing in the tribe. Suggest making burned clay containers to store water or food instead of metal containers. From here we will obtain this calcined clay.

Once we have the ingredients, first we gradually mix the clay, the kaolin and the charred clay remains with water. Once we obtained the mass for the bricks, we included half the volume of the mass with sawdust. The term volume was something that implant not long ago, all knew the weight, distances and surface, but the volume does not. Take advantage of this to teach them some easy formulas to calculate the surface and volume of certain geometric figures to people who were learning mathematical calculations.

Once we have everything together in the molds of the bricks, the process equals normal bricks. Let them dry in the sun for 3 days, and then bake them for a whole day.

We continue this process of manufacturing both brick, cement and refractory bricks for 2 more weeks. Until the raw materials were exhausted.

We are in the middle of November and soon we will have to harvest the pea and the potatoes. Before that time came I wanted to build the support for the water wheel, in fact we would not take long, the difficult thing would be to move the wheel to its correct place.

For 2 days we built the supports, I decided that the wheel would be fastened on both sides of the channel, in this way the weight would be distributed better. The supports have the shape of a hexagonal base tower and it is narrowed upwards, its pyramid-like shape has greater stability unlike a common tower. We wait another 3 days for the mortar to dry, on the fourth day together with most of the men of the tribe we get to lift and place the wheel on the supports. By the time we finished placing it, the sun was already setting. Tomorrow I will start doing my method so that the movement of the wheel makes the piston of the air pump move, we will also finish the channel.

As I decided yesterday I started making a piece of wood which would make the movement of the piston. Together with two villagers I made a piece of wood octagonally, like the Ferris wheel, but it was solid and in the center a hole where it would fit the axis of the wheel, in the outer corners of the piece I put some small bars improvised cogwheel mode. With this the part of the wheel was made. Now I would have to do the piston part. To this join a wooden bar attached to the piston with bronze nails. On the free end I also put a wooden hook with nails, this cost me to do it since it required me to have an exact angle to work.

When finished, I decided to proceed with the test. By the time I was ready to take the test, I realized that the whole tribe had gathered around the air pump. Apparently everyone wanted to see if the hard work done during these weeks had been a success.

-well, let's start, open the canal hatch- to my words two men from the village raised a thick wooden board that covered the end of the canal where it would enter the water, I made this mechanism to regulate the amount of water that would pass through the channel, by lifting it a little water already started to circulate, at the other end two other men were commissioned in this case to place a piece of mother so that the water from the river did not enter that side and that only the water from the channel pass. When the water reached the necessary height to move the wheel, it began to move a little. When the force of the water was sufficient the wheel began to move completely, then everyone saw how the piston hook was hooked to one of the bars of the cogwheel and rose along with the cogwheel, when doing this movement the piston went up, when the hook was about to reach the top of the wheel, it unhooked and lowered, this caused the piston to lower due to its own weight, in doing so it caused a strong current of air, once again when the hook was about to reach the bottom. He reattached another bar of the cogwheel and climbed back up.

-ALL RIGHT!!! WE GOT IT - all the villagers shouted with excitement, many had their doubts about this project, but everyone was happy that it was a success. Despite the excitement of the surroundings I could only observe calmly the movement of the piston. We had managed to produce hydraulic power.

-Brother / Aren !!!! -

By the time I realized my sisters threw themselves at me and hugged me, this made me fall down on the floor, on top of me are my sisters.

-you got it brother- Aria

-you are amazing brother- Nao

-We've got it, Aren- Ellen

I would be happy about this situation, if it was not because they hugged me very hard, I can feel their bodies pressing against mine. I can feel 6 lumps ... wait 6 lumps, do not tell me ... Ellen, Aria and ... Nao. Can not be!!! They are already growing if this continues she will be like her sisters, I do not think I can be calm, even though my sisters have them great they are more aware of this they do not usually hug me very much, but Nao is different, she hugs me with frequency. Ahhh ... I'll have to do something about it.
