@Doc Restating HandyDan, Aircrete is an application (not a type per se) of cement that can withstand higher temperatures than most other applications. @Talyn71 demonstrates the concept well in this video where a propane torch is left in direct contact with a 1.5" x 6" x 6" slab for 15 minutes after which he easily picks it up and lays his hand on the back side.
I went thru the straw bale scene 15 years ago and was able to get county approval.
Wow! Please share your story about that. What steps were required? What challenges did you encounter? Did the county approve your home as an exception, or add strawbale technology into the local codes?
Well, I love my land, I can afford some red tape if need be, but I would like to have my electricity from the pole and not by generator. That requires approval from society. I obtained the copy of the plans for Steve's Dome from domegia, and the needed details are just not there. It looks like I will pretty much have to have the entire dwelling drawn up and engineered and you are probably right, throwing the cost right out of the ballpark. I would love to build this myself but I am getting old and if it takes 10 years I'll be lucky to lift an aircrete block by then. Thanks for the reply, and I agree with the theory.
That's the approach I was settling on--pouring through the crawlspace vents. I too considered maybe working on a raise platform to gravity-boost the pressure.
FWIW, the contractor I used lined the lower few inches of the foundation down over the footer lip with "drain matting". If moisture condensed and ran down the inner foundation wall it would have a small space to continue seeping downward. I suppose a major plumbing leak also would be at least mitigated by this small gap. The matting was anchored directly into the foundation using a hammer drill and manually hammered concrete anchors. I think this product is also referred to as "dimple matting" or "wall drainage". They poured the concrete directly onto 6mil taped plastic right up to the drain mat.
Plan on your house being more humid for the first couple days as the concrete cures. Since they did mine in one shot we awoke the next morning to tropical humidity and rivulets running down all the windows (it was Dec).
I closed up my vents a few weeks after the concrete was poured. I plan to finish encapsulating by lining the foundation walls with sheet insulation.
@gemniii Standard cement mixers are more expensive, heavy, and large, yet less effective than a hand held drill mixer. Standard concrete mixers are designed to mix sand (little hard bits) and gravel (larger hard bits) with cement and minimal water. Mixing very wet mud with foam instead of hard bits seems to require less torque, but more horse power or something like that.
As the present primary moderator of this noble forum, there are no rules that I can think of. If anyone does find some rule set somewhere, let me know.
I certainly do delete accounts that are used solely for advertising their own unrelated ponzie schemes via internet scam operations. If you are reading this then that almost certainly does not apply to you.
Here are a few guidelines to help keep this arena enjoyable and beneficial to all:
Before making a new post, do a quick search to attempt to find an existing conversation that is related or covers the exact same material. If one exists, read it, make comments and ask further questions there to get your specific questions answered. If nothing exists on the topic or you feel that a new fresh conversation is in order then please create a new post.
When addressing a colleague on this forum, please do so with a little extra respect. Be honest, be frank, be clear, and be gentle when feasible.
Show gratitude for colleagues' posts, but not necessarily with written replies that everyone else must read - consider upvoting their post instead (note the little voting tool at the bottom right of every post) as that is a great way to thank them for a good post.
Keep the posts informational, inquisitive, and useful. Minimize small talk, banter, attacking, or venting.
Do down vote or flag posts that seem inappropriate or needlessly disrespectful (see the 3 dots stacked to the right of the voting tool)
@Zander Well I found out the easy way to do it.
The combination of my old eyes, my cheap laptop screen and the light orange coloring made me miss the X in the upper left hand corner of the pop up. On a better screen I saw the X and clicking on the X disabled notifications.
