[Attachment(s) from Charmaine Taylor included below]

If you think horizontally…the way adobes are laid rising higher to make a dome then there is a ton of info on this building method.

Also --using a MOLD- metal framed, one foot wide  sorta like a rammed earth or stone wall slipform,  Ken Kern adapted a moveable mold  that moved sideways around in a circle as the wall built up... in the 60's called a Magdiel form-  by 2 guys who invented it.  you could recreate it easily once seen. or even like a modified RE mold form.

It is an open ended box on one side, you fill with dirt/ sawdust or paper mix, let cure a bit, then slide over and fill again, you use a center pole, and a chain to  keep the circle correct, moving ever up and inward.

there is a lot more description in one of his old books..he was actually the first to play with clay and sawdust, paper, cement ion awl mixes, and his last unfinished book was about a "cob" type house made with alt. materials 

-- search is name..his daughter still sells his reprint books near Napa CA.   Owner Built house was one of the first.. OB Revisited/house of Clay  may be the right book.

a LONG article mentions  the MAGDIEL form here-

attached is just ONE way to used PC-adobe  blocks  going vertical..to do the same thing in a dome shape. but domes required good engineering..thankfully lots of info avail on how to.

[papercreters] BLACKJACK AE ON PAPERCRETE--



Tasha… using asphalt emulation AE- (Henry's 107 and other  roof tar, basement waterproofing, road  asphalt mixes)  have been used extensively in many ways.  an inventor/house builder  in the 1930s used it to mix with ground cardboard and cement/clay ( sound familiar?) to create Rub-R-Slate…and you just add some to a DRAINED PC mix…use in dry weather, and as the clay-AE -water  mix evaporates it seals up to make a strong water resistant, even water proof covering. it is NON toxic..this is asphalt, not asbestos, which people mix up… standard black roofing paper is paper coated with AE used in house wrap, it's a long term use  material.


I have used it straight right over old punk wood siding that  I could not replace yet, then painted over it, it still is lasting 8 years later, it seals off the  pours ness of any material it is on, which is a good thing.

it looks like pudding or wetter in the can, is cheap,and dries a dark drown. if you mix it, like I do, with clay, paper, lime, sand, ratios  as a plaster it dries lighter in color.

adobe makers use it too in sun dried adobe bricks..so do try it, 

there is always some question about smell..read the pail,it is safer than some paints, it is not ' offgassing' anything nasty.it has a  road tar type smell, like most things do  which ,goes away when dry, like house paint does.

you  don't need much, and don't try to use it in wet weather, it needs to evaporate the water out of the mix, and the fine fine clay in the  mix gives a 'body' to it so it adheres to paper or cinder block  very well.

Re: [papercreters] WAS small movable mold NOW Blackjack



Has anyone put Blackjack on an exposed papercrete structure?
I've put it on old composite roofing, and it works great for that.

Re: [papercreters] small movable mold?



This looks like a slip form to me, with the added radius connection for forming domes. I used a similar scheme when I did a tire dome, a measurement attached to the center of the sphere and used to place each tire. For years I dreamed of using a commercial curb machine, like is used to make the curbs along streets, but tethered to a dome center instead of guided along a straight line.

Re: [papercreters] Re: FLYASH..rice hulls/ash (RHA)



I'm not sure about refractory cement. I think the clay content and type is what allows it to be used in a fireplace, or high temperature variable space.


Heavy metals, if in the flyash would be bound up in the cured mix, wouldn't they? Isn't the risk with heavy metals getting them into your body?


I recall a recent patent for a very porous non-alkali cement filter that allowed 3 strains of bacteria to live in the cement after cure. It purified contaminated water making a brackish pond clear in a short time. The cement was not Portland but a geopolymer cement (not affordable for me).

Re: [papercreters] Re: FLYASH..rice hulls/ash (RHA)



i like the plasticity part and get what you are saying about 'toxixity'-just had some memory bells ringing about 

heavy metals or similar in flyash that i wouldn't want washing or blowing into my garden and living areas (i do sculpture and work in my backyard!)

i realize that portland itself is 'toxic' if inhaled and for that reason i use extreme caution and only mix in small amounts. I wonder now if the dark 

brown component of the refractory concrete i just got could be fly ash-? will get googling- a chemistry degree would come in handy some days.

Toxicity? Everything has a toxicity, especially nothing. It is just a measure, like temperature. Water, air, lettuce, aspirin, radon..... everything has a toxicity number. 


"Fairly" is a word like "very". It is gut feel and has no quantification. Since flyash is the byproduct of burning coal for energy, the toxicity is not created by using it in a concrete or PC mix. I don't think concrete is more toxic because flyash is added, perhaps less because less Portland is used. The environmental impact of using flyash in the mix is less than using all Portland.


Type F flyash is a bit more expensive, more pozzolonic, and harder to find than Type C. My regular cement product supplier process their own type F. I believe it is Type F from Type C. This apparently removes some of the reputed contaminants in Type C. Type F is a dark gray not the light brown like type C, hence it gives a differently colored finished product. Type C is cheaper than Portland, Type F is about the same price as Portland. I do not know how Type F is processed. It could be that the energy required to process it makes the environmental impact the same as using Portland.


I have heard that road repairs in the cold weather areas use flyash because it lessens the risk of freeze cracking on freshly poured mixes. I notice more plasticity in the mixes I use.

isn't fly ash fairly toxic?i haven't got my notes with me but I did research it once and it sounded a little bit scary from memory?

No.

http://en.wikipedia.org/wiki/Fly_ash

Fly ash (at least the ones I have heard of having positive effects) are pozzolanic, unlike wood ash. Wood ash would simply be another filler, like paper but without the higher air entrainment properties of paper pulp.

Obviously, YMMV and feel free to test things out and let us know if you find differently.

[papercreters] FLYASH..rice hulls/ash (RHA) [2 Attachments]

[Attachment(s) from Charmaine Taylor included below]

Bobby- the entire OPC industry  has looked at various additives for years to reduce costs and weight /amount of cement from their mixes.  most average people can't get 'real' flash, but might be able to get rice hull ash or similar. rice hulls themselves are little ovals with an air pocket inside, when burned the ash works even better.  mixing hulls with paper is just one more reason I call papercrete an "idea"..the options to add organics and others are endless..


does 
does eveyone have the 14 page paper on Rice Hull House building by Oliver?  if not I ca add it here and hope it is accessible.
also Stephens build earth bag huts of rice hulls..lightweight, insulating.



Use of fly ash

 I think it says that we should put as least as much fly ash in our

papercrete as concrete.

Re: [papercreters] Use of fly ash



The use of less water in concrete will not carry over to papercrete in general because you have to have enough water to pulp the paper, which is a lot more than you would use for the equivalent amount of cement for concrete. Workability is probably not going to change much either since pc is already like potter's clay in workability. It may slightly affect the cost of the mix - if flyash is cheap and local.

Hopefully, these advantages will carry over to papercrete.

[papercreters] HIGHEST R VALUE PC + FREE ARTICLES/BOOKS



Good heavens, I tied to post  my reply thru the Yahoo site...sorry for all the garbage text!!!

AIR entrainment is what will give the R value,sand and heavy additives will
just offer mass..there is a trade off of 2' thick clay/adobe wall that
soaks up sun, vs a 40" straw bale that keeps warmth in and cold out at R 50
both opposites.

the best of both is a fluffy papercrete very thick, but lightweight,where
as water evaporates air pockets remain.

in the cement/concrete world adding the flyash and other air entrainment
liquids ( to cause bubblers) lighten the cement and insulate better, again
they seek the best of both.

i'd research how the cement/concrete makers do this for real info, as the
PC world is all individual experiments without the serious, rigorous
testing.

I've seen several articles on this type of insulating research online.

this BOOK-- 20469839-Advanced-Concrete-Technology  IS FREE to READ 
 is 280 pages of all things concrete and has tech info on air additives.

it can be found on the site www.scribd.com, or in my Guides asa freebie

SCRIBD is the best site- many many free books-- ON ANY TOPIC- amazing- I put up my own writing- they pester you until you contribute YOUR works.


GO TO WWW.SCRIBD.COM search by key word-- 




they want you to upload your own writing- anything is acceptable that is

useful-- maybe write up your experience on building something- or what you know?

but it will annoy you until you do donate something. But you can get

them   books  and info free, so it is worth it.

 

BOOKS AT SCRIBD I HAVE FOUND :

USE THE  7 OR 8 DIGIT CODE IN THE  'SEARCH' BOX TO FIND THESE TITLES: (MANY of the  following titles are ALREADY  on my  CD GUIDES, or ONLINE via Papercrete.com).
