I got a $14 corded drill and a $3 cement mixer attachment. I had to use duct tape at the connection because of the soft metal but I've done about 600 gallons so far and I'm very happy that I didn't spend thousands of dollars

I did some experiments and I kept finding that the cement helped a lot with a cracking. The clay just made things worse. It could be a preparation issue. I can say aluminum foil has been a game changer. Mostly in the roof at the moment The infrared light is an important part to understand about insulation. And it seems the coverage only needs to be on the sunny side.

My guess: the cracking is mostly due to the shrinkage - most of the volume is wood anyway and wood _will_ move with the weather. That's why I doubt it will be durable enough in weather with large air humidity swing between seasons.

@radicalgastronomy 5 ай бұрын

@@col0342 I agree, in part. I think this is wood shrinkage. The saw dust I used was super fresh, and lost a good bit of volume in the curing process. I was just sent a Mother Earth article about a man who developed a similar technique in the 1940’s. He found 1 year aged sawdust to be perfect (softwoods). He also added clay and Diatomaceous Earth to the mix. As to durability, my oldest sections are 4 years in, and show no sign of degradation. The lime plaster helps regulate the humidity within the wall. Even un plastered sections on the outside are rock solid after three years in the elements. My climate is arid.

@col0342 5 ай бұрын

@@radicalgastronomy thank you for the extra info. It's hard to conduct experiments when the time scales needed are in (low) 10s of years and one factor is the (time and geographically variable) weather. Does require a willingness to take a good deal of risk when using the technique for something as expensive as a home, I might give a try with a shed tho.

I liked your idea about the next build you do having the wood timbers on the inside and the dustcrete a solid wall just outside the framing structure. Im trying to decide how i want my walls on my next build and i really like that idea. Im in missouri. Tell me though, it seems that the best wall would be made all at once to avoid cracking, but that seems impossible for myself to do and i would prefer to just do a wall at a time like you were doing. So how could it be done without getting cold joint cracks everywhere. Im thinking if you just used lime (doesnt it set up much slower than cement?) and also add some sort of mesh reinforcement or fiber (straw or fiberglass etc) to the dustcrete that should help. Is strawcrete a thing? Maybe a batch of half straw/half sawdust would give it better crack performance? Do the cracks even matter as long as you let it crack first and then finish with lime or clay, does that cover the crack so its never seen or would it keep cracking there? Or maybe it should be designed with control joints between batches/walls? By the way how are those tests coming with just lime and whatever else...

Have you experimented (or have review from others experimenters) about loard bearing dustcrete structures ? What would be the minimal thickness for instance for a wall? And roof sheeting ?

@radicalgastronomy 10 ай бұрын

I’ll cover this next week, but I believe this is possible with a reinforced bond beam at the top of the wall. If I was doing it I would wait 60 days after packing and form stripping. Perhaps I’ll do some load tests at different thicknesses. I wonder about corners, too…

I’m using mixed spruce and fir. Most wood types should work, but hardwoods may be slightly less insulating. I haven’t tried, so I can’t say for sure.

Doing this in a wet or '" coastal area" is done with burned oyster shells(lime) to create " tabby" . Imagine this wall with oyster shells in it. Tabby is the original Spanish and Indian method for east coast

@kristofp72 2 ай бұрын

You can probably hide the cracks well enough with applying a mesh of fiberglass or something before plastering. The cracks arent a big deal anyway since the dustcrete isn't load bearing and your wooden structure holds everything. Personally I'd add tiles or wooden shingles to the roof instead of the metal roof just for the looks. I want to learn about timber framing myself it's on my bucket list unfortunately timber here (Belgium) is very expensive as a building material.

I'm no expert, but I believe the dolomite lime contains more pozzolans. These cause lime to have a hydraulic set like Portland cement. You could try adding diatomaceous earth, fly ash, etc in your tests.

@@jakeboone6241 It depends on what you mean. If you mean without a frame, it is possible (but unconfirmed) that dustcrete could bear a load. If you mean super compacted, it can be done, but the greater the compaction the less insulation value.

This seems so promising with so many possible uses, could it be a stucco substitute? I have wood panels on my house that have aged relatively well except for where Virginia creeper Vines have creeped in and allowed moisture and cracking, as I remove them it occurred to me that spackling the house with a mixture like this could provide a paint like powerful protective coating?
