I cover a few more details on building with rammed earth. This footage was taken a few weeks ago and I never got around to publishing it.

Excellent content. I've been reading so much about concrete, how its made, pozzolans, etc.. etc.. The one thing I keep seeing with those having successful rammed earth (RE) projects is that they either go with gravel/sand/portland (no clay) or they have a strong and very obvious clay representation in their dirt. One of the biggest things you have to be concerned about is the amount of silt in your clay, because its very unstable with water at < 150 microns, and you need to have well graded sand. Well graded means "enough"/"good" representation of all sizes of sand particles (from no 4 to no 200 sieve). Then you'll have less air pockets and higher density, which when combined with the portland increases the strength. In any event Poorly grade soils in general are more apt to be susceptible to soil liquefaction. I've also read lime is a better stabilizer to use if you're using a clay soil and if a sandy soil, then use portland. While it would be more work, I'm wondering, for my own project, if I'll need to sift through it all and ensure my grade is acceptable. We'll see. Test blocks are going to be made. Lots of them. Thanks again. I'm inspired!!

it is well worth adding stabilizers... i would not build again without portland or lime

Rammed earth is really a mixed bag when it comes to strength. If anyone's planning to make a house out of it, I'd recommend using it only as a non-loadbearing wall flanked by timber frames. Less likely to get a surprise asshole building inspector to condemn your hard work for demolition out of "safety concerns." The shear strength can be improved by adding a reinforcing mesh or fiber into the mix. Or use round geometry. Crumbling and abrasion issues can be addressed with a coating of some sort, though it'll get you flamed by rammed earth purists who believe everything should be breathable or the layers should be visible. Personally, unless it has a considerable amount of cement added in, I'd clad the walls to make it last than to have it look pretty as it falls on me after a stiff breeze.

@dirtbagbuilder9568 3 жыл бұрын

Exactly. Like all building materials the plan needs to be fit to their specific strengths and limitations. Square peg round hole is a bad design technique.

@bigonprivacy2708 Жыл бұрын

It also helps your cause with the building inspector if you follow the code, which in Texas you have to demonstrate a compressive strength, like the approved adobe brick, of 300 psi. So make test core samples and get those tested by an engineering firm. I called many of these firms and was able to work out a good deal that testing 10 samples (5 at 7 days and 5 at 28 days) would cost less than $350. Once you're able to show verifiable and accepted results, you're good to go. Repeat by creating 7 & 28 set samples aside "randomly" while you build the final house. By doing so you can establish that your final mixes also met the code. Once done, that inspector cannot do anything. Also, when building a house, you should use vertical and horizontal rebar and finish with a bond beam that goes across the entire top of all load bearing walls (for seismic issues). Finally, have eaves and cover to protect your walls long term. UPDATE (I've read too many studies that show horizontal rebar actually increases space issues and weakens the walls. You should ONLY use vertical rebar). You do this, then you're literally building as good as a contractor, and likely better since its your house and you'll be extremely careful on creating a good product.

Sand is actually what's meant to be used for rammed earth. 80% sand, 10% clay, 10% water

Wrong

@akifsyed17 Жыл бұрын

Absolutely wrong.

@bigonprivacy2708 Жыл бұрын

Yes, that is not correct. If you use so much sand then you must use more aggregate (gravel). But without a minimum of 20% clay, you'll not get the bonding effect that occurs (along with the 5 to 10% portland). Clay is non-neutral, which is why it provides the adhesion in the mix besides the portland, which is added more for the inspectors and because of the sand. The more clay you have, then the likelihood you can use lime instead of cement.
