Lego Aircrete Bricks?
I have an idea. What if you made the blocks like legos. Is it possible to be able to make these blocks stand without the use of counter weights. If you could, you could speed up the time it takes build domes in particular. Arches don't have that problem because you can pull out the form after the blocks are laid down on top of it. Domes don't have any place to pull out a sold form after all of the blocks are laid down. That is why I am bringing this up. You could put the studs on an angle so the blocks would naturally rest to make a dome configuration. So, is this feasible.
If not lego studs, perhaps tongue and groove bricks could work.
Nearly every aircrete builder comes to this point in their thought process early in their career. Welcome.
It is a valid concept. It has been explored by a few - at great cost.
The limiting factor in this concept is making the forms, and or cutting and shaping the blocks. Up to this point, the effort required to actually create an aircrete (or concrete) block that interlocks has proven to be more costly than the effort to work with clumsy straight blocks.
Other factors that add exponentially to the cost of creating interlocking blocks are:
- The different size / shapes of blocks required for each successive course especially in the top 30% of a dome
- The different size / shapes of blocks that are required depending on the size of the dome
@Zander What about a tongue and groove? Forms can be made for this and you could control the angles the blocks are set at. You would not need several forms for several type of blocks for certain angles.
Based on my experiences and the research that I have done on this topic, it's not so much that building the forms or molds is so difficult per se, but the real challenge is releasing the newly formed blocks out of their molds.
In other words, it is simple enough to build a form to create a particular shape of concrete or aircrete. But extracting that shape often requires destroying the mold, disassembling the mold, or breaking off that intricate piece of aircrete.
Yes, even something as simple as tongue and groove becomes way more trouble than it's worth real fast. For many aircrete builders, it is a continuous labor of love just to create the simplest rectangular shaped blocks.
@Zander Thank you for your help. I'll explore other possibilities that can be done with speeding up the creation of domes. I understand it sounds like I'm in a rush. I am thinking a little more of an industrial process that can get as many people in as many high quality houses as possible. It's an idea that I am floating. Also, thank you for the welcoming.
