This is a simple aircrete machine based on the principle of inversion of pressure and it works without any motor. It is completely made from recycled material. The machine can make aircrete blocks fast, no noise and pollution free using compressed air.
An aircrete machine operates by compressing sand and adding water to create a mixture that can be laid down as a slab. The sand is first placed on a hopper, which is then crushed into gravel and then lifted up into the construction hopper by a conveyor belt or chain. The material is then placed in the mixer where it is mixed with water and compressed into slabs.
The entire point of alternative building technology is to make the process easier and more efficient. To that end, let’s look at a very simple aircrete machine design you can use over and over again:
Takeaway: Here’s a simple plan for building an aircrete machine you can use to make blocks.
Materials Needed
The materials needed to build a simple aircrete machine are as follows:
- Molds. You can get molds from your local hardware store. Make sure they are compatible with the compressor you will be using, as some compressors are designed to use only certain types of nozzle attachments.
- Air compressor. This is the most important piece of equipment in this project, so it’s best to invest in one that is durable, powerful and has a long cord so you can use it without being restricted by an extension cord (or multiple extension cords). If you plan on using your aircrete machine often, consider purchasing two compressors – one for larger jobs like building houses and another for smaller tasks such as making concrete furniture or garden statues.
- Air hose/tube: The length of this hose depends on how far away from where you will be working with concrete is located (i.e., how much space there is between where your compressor sits and where the mold sits).
- Concrete mix: Use pre-mixed concrete if possible; otherwise mix dry ingredients together before adding water each time before pouring into molds (it’s easier!). Be sure not overfill these molds; leave room at top so finished product has room expand while curing over time (this could take several days).
The Hopper Design
The hopper design is critical. It should be sturdy and stable, as well as easy to clean. This will help ensure that the concrete is mixed at a consistent rate so that it doesn’t clump together or become too wet. If you’re working with large batches of concrete, it’s also important that the hopper can hold enough material so that you aren’t tied up moving around your machine all day.
You may want to consider making two hoppers: one for mixing dry ingredients like sand and gravels; another for dry ingredients such as pea gravel and cement powder (which are harder to mix). You’ll have more control over how much water gets added by having these separate containers rather than just dumping everything into one large container at once – this leads us into our next point.
The Air Compressor and Air Tube
The air compressor and air tube are the two most important components of your ACM. The compressor is used to store energy in the form of pressurized gas, while the tube transports this energy from one place to another.
The bulk of an air compressor consists of three parts: an electric motor, a tank for storing compressed air, and some sort of mechanism that allows the tank’s contents to be released at regulated pressures. This last part can take many forms; for example, some compressors use valves or pistons rather than valves (this is what we’ll be using).
To ensure that your ACM functions properly at all times, it’s important to choose components with high-quality materials and well-made manufacturing processes. For example:
- A car battery may work as a power source for small-scale applications like home heating systems or portable refrigerators; however, it isn’t durable enough for industrial applications where there are higher demands for performance over time.
Placing the Tubes in the Mold
- Place the tubes in the mold
- Make sure they are not too close together
- Make sure they are not too far apart
- Make sure they are not too high or too low
Mixing and Pouring the Concrete
Mixing and Pouring the Concrete
To mix the concrete, put water into a bucket. The amount of water should be equal to two parts of concrete powder. Add a drop of wax, which can be purchased at a hardware store. Mix by hand until there are no dry patches left in your mixture; if you need more time for mixing, use an electric drill for mixing purposes only (do not use it to drill holes into your mold). Next, fill up one end of your mold with this mixture and tap it on top so that it spreads evenly throughout all sides and corners – this will ensure that all layers are even when you pour them later on!
Once your first layer has been poured, let it sit for about 30 minutes before adding another layer – during this time period make sure that no bubbles remain (if any do come up during pouring process then press them back down using trowel). Repeat this process until all layers have been poured & cured – once done remove tubes from inside within 24 hours after curing takes place
Tips and tricks for aircrete success.
If a vacuum is not available, place a piece of plastic over the top of the aircrete being cast to prevent air from escaping. This will help keep the concrete from drying out while allowing you to apply more pressure to it as it sets up.
When preparing your mold, make sure that there are no holes or gaps through which air can escape during casting. If there are any such holes or gaps in your mold, cover them with duct tape prior to pouring and casting aircrete into them.
Final words
AirCrete is an innovative building material for both the aspiring and the professional innovator. It’s a great way to keep your home cool in the summer, and warm in the winter. It’s durable and flexible, so you don’t have to worry about cracking or warping with time like other materials do. The material can be used as a replacement for traditional concrete mixes due to improved insulative properties (better R Values).
