Re: [Biofuel] Soap aerated concrete
The process you mention is the process to make Hebel. The problem with using that process, is you need heat (ie Autoclave), and the product is reactive, so requires epoxy coated re-inforcing. The process I am interested in uses externally generated bubbles of less than 1mm diameter, mixed with (fine sand) mortar. This creates a product similar to Hebel, but with better (from my searching, anyway) water properties. (Hebel cannot be wet as it looses strength) Proper aerated concrete retains much of the strength of normal concrete. regards Doug On Tuesday 15 February 2005 8:03, Greg Harbican wrote: I don't know about using soap, but, professionals make it by mixing in aluminum chips.

There are many recipes for how people make/use homemade soap for dishes. I would suggest you make a batch of concrete as the directions state to get an idea how the consistency is supposed to be at each stage and then experiment substituting with homemade soap -whatever recipe you decide to use. Perhaps you will need to adjust your soap recipe (or quantities needed) to end up with a similar outcome.

Re: [Biofuel] Soap aerated concrete
Perlites and found with the Borates and all part of the volcanic geological evolution. We have a lot of Perlites in our Sierra Nevadas in California. Same with borates (borax). Borates, perlites, colemanites, - all that stuff can be found anywhere you have an escarpment of raised mountains due to ancient volcanic magma scarns and earthquake activity especially next to an arid desert bowl. What is Perlite? http://www.perlite.info/hbk/0034409.htm Perlite is not a trade name but a generic term for naturally occurring siliceous volcanic rock. The distinguishing feature which sets perlite apart from other volcanic glasses is that when heated to a suitable point in its softening range, it expands from four to twenty times its original volume. This expansion process is due to the presence of two to six percent combined water in the crude perlite rock. When quickly heated to above 1600 F (870 C) the crude rock pops in a manner similar to popcorn as the combined water vaporizes and creates countless tiny bubbles in the softened glassy particles. It is these tiny glass-sealed bubbles which account for the amazing lightweight and other exceptional physical properties of expanded perlite. The expansion process also creates one of perlite's most distinguishing characteristics: its white color. While the crude perlite rock may range from transparent to light gray to glossy black, the color of expanded perlite ranges from snowy white to grayish white. Expanded perlite can be manufactured to weigh from 2 lbs/ft3 (32 kg/m3) to 15 lb/ft3 (240 kg/m3) making it adaptable for numerous uses, including filtration, horticultural applications, insulation, inert carriers and a multitude of filler applications. --- Guag Meister [EMAIL PROTECTED] wrote: Hi All ; Could I ask a stupid question?

Guag - One of my favoite borates is called Ulexite. Ulexite is called a natural fiber optic by scientists and TV rock by children. It exists in oxidized form as a rock but you can see throught the rock because it allows light to pass through its crystalline structure - thus transmistting the light.

Re: [Biofuel] Soap aerated concrete
Perlite is made from a siliceous volcanic rock for horticultural use and also for insulation. When heated to a suitable point in its softening range, it expands from four to twenty times its original volume. This expansion is due to the presence of two to six percent combined water in the crude perlite rock. When quickly heated to above 1600¡F (871¡C), the crude rock pops in a manner similar to popcorn as the combined water vaporizes and creates countless tiny bubbles which account for the amazing light weight and other exceptional physical properties of expanded perlite. So it's very similar to rice husk ash, which, when properly prepared, consists mainly of myriad tiny glass bubbles. A major difference is that Perlite is a product, rice husk is one of the world's most underutilised waste materials. Perlite is very fragile and makes an unpleasant dust. Wear a breathing mask. Reject perlite of a suitable grade can often be obtained free of charge (or at low cost) from the manufacturers.

Re: [Biofuel] Soap aerated concrete
Nothing to do with soap, but do you know about this? http://journeytoforever.org/at_woodstove-allen.html Rice-husk stoves - Appropriate technology: Journey to Forever This stuff is great! We're using it to build charcoal-burning stoves, it's an excellent insulator. Have a look at this picture: http://journeytoforever.org/bflpics/rhahand2.jpg Those coals are really hot! Reduced strength, as you say, but we find that a mix of 1:3 up to 1:1 cement to rice husk ash by weight is pretty strong, and since the RHA is much lighter than the cement, in fact you don't use a lot of cement. It's a bit like pumice or something. Doesn't weigh very much. The rice husk burner works very well, but if you want to put it in a 55-gal/200 litre oil drum, as we did, you'll have to make the cage slightly smaller.

There are many recipes for how people make/use homemade soap for dishes. I would suggest you make a batch of concrete as the directions state to get an idea how the consistency is supposed to be at each stage and then experiment substituting with homemade soap -whatever recipe you decide to use. Perhaps you will need to adjust your soap recipe (or quantities needed) to end up with a similar outcome. I would love to hear of your results, email me privately if you don't mind when you experiment.

Re: [Biofuel] Soap aerated concrete
I don't know about using soap, but, professionals make it by mixing in aluminum chips. The aluminum reacts with the calcium hydroxide, and produces aluminum hydroxide and H2 gas.

Re: [Biofuel] Soap aerated concrete
I used Perlite mixed with refractory cement in my aluminum casting furnace. The walls saw temperatures surpassing 2000F, it was working well. The mixture was 50/50, and the perlite is very light-weight, reducing the overall mass of the structure. -- Martin K Keith Addison wrote: Hi Doug Nothing to do with soap, but do you know about this? http://journeytoforever.org/at_woodstove-allen.html Rice-husk stoves - Appropriate technology: Journey to Forever This stuff is great!

Re: [Biofuel] Soap aerated concrete
Hi, I am searching for information on making aerated concrete. For those [snip] ... ... [snip] Can anyone help me?? regards Doug (I am interested in making tilt up concrete panels for a building.) A word of warning - get professional advice on this ie a structural engineer, before you actually use it. I had some experience with this type of technology in the early '90's and if I remember correctly, the strength of the aerated concrete, is between 0.1 0.2 that of normal concrete - 4.5MPa Vs 20 - 40MPa. If in turn you are doing tilt-up construction, this lower strength could cause problems when the panels are tilted - unless you get your reinforcment right, the panel will snap when being lifted, or are you tilting the whole forming bed? You might want to have a look at this site, they have some info there, CAD drawings etc that might be of interest: http://www.hebelaustralia.com.au/ Regards, Andrew Lowe ___ Biofuel mailing list [EMAIL PROTECTED] http://wwia.org/mailman/listinfo.cgi/biofuel Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Biofuel archives at Infoarchive.net (searchable): http://infoarchive.net/sgroup/biofuel/
