@HandyDanIn regards to using air Crete for a floor, what reinforcing would you use and how thick would you make it. My current application would be a base for patio pavers but I’m also interested in using it for the floor elsewhere.
Something I think we need to consider is that the demand for single family homes are shrinking. Middle density neighborhoods, duplexes, multiplexes, etc. are rising in popularity. As the single family zoning laws get slowly rolled back, there will be more of what there is demand for. So what if you made these middle density building out of aircrete? It should be possible. Would you need wood for all the platforms for the floors? Could you use something else? What do you guys think?
By the way, sorry I have not been on for a while. I've been busy.
Hi to all AirCeters,
I just started to prepare blocks for our dome-project. And I put some samples to the material testing lab at the university of Costa Rica. The results are 3 kg/cm2. This means about 42.7 pounds / square inch. In the cross-section image of the E-Handbook there are noted 70 lb/si.
Can I use my blocks? Or what can I do to improve the strength of my blocks? (I use the original Domegaia recipe and form). Thank you very much for your comments.
would you build a ferrocement home with dome roof and earth sheltering in FL? As long as heat/moisture producing elements are already outside the enclosed space and indoor rooms have windows for ventilation and A/C for the hottest summer months? Would you still use a thick vapor barrier between the ferrocement roof/walls and the dirt sheltering it, or would the waterproofing in the ferrocement be enough as is? Thanks so much in advance! Do you know someone who could do the engineering/plans for our home?
@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.
@KnowItAllTeen Not fractals. But, yes, arches can readily branch and intersect with other arches at any angle, especially if the arches are of the same shape and size. Architecturally and structurally, domes do seems to be the perfect hub, node, or joint between arches.
@knowitallteen Nevertheless, they're a company. Like all companies, they use the profit to expand their cause or business. So, when that cause is providing people skills and tools to build their own, you have something great that is rolling.
@zander would it be better to make one giant done or a few smaller ones
Only you can answer that question. There are pros and cons to both approaches. This question applies to dome homes similarly to how it would apply to any other building method.
Smaller structures are generally easier to build. This is particularly true with domes because they tend to get taller as they get wider. The more work that must be done from a ladder or scaffold the more risk of injury exists. Small structures are the best way to learn any building method. Perhaps the best approach to learning any building style is to first build a cat house, then a dog house, then a cabin, then a small home. Many people can't afford such luxuries of time and jump right into it. That works too.
Larger domes generally cost less per cubic foot, assuming the same wall thickness. This includes the cost of materials as well as labor.
Several smaller structures provide more autonomy and privacy for members of the household. Having multiple smaller specialized structures can better integrate with the terrain and encourage a more outdoor lifestyle. That being said, domes can be quite easily conjoined directly or via arched passages to create a seamless domeplex where each dome may be compared to a "room" in a modern "house".
I am sure there are many more factors that could be considered on this topic.
@zander I have an idea. When I decide to build my house, I will install a ceiling fan to make up for the discomfort and promote the cooling. A dome is like a funnel that is upside down. It can help draw in warmer air to the top and keep the cold air towards the bottom.
I have been watching the La Palma situation. I was thinking how is this going to turn around for good? I am wondering if all that ash could be used for good since so many plants were destroyed. I assume not all ash is the same so it would vary per volcano but thoughts on maybe using it to help rebuild right?
@obo-martin Regarding structural integrity, a 10-12 inch round hole should not be a significant structural weakness, assuming your wall thickness is at least 3.5 inches. Circular penetrations have the least structural impact. Read this post describing the impact of earthquakes on raw cut circular openings for windows that were about 4 feet diameter cut into 3.5" thick dome walls.
