mega-low non explosive

[S. Toppholzer]

Gentlemen

A while ago I happened to stumble over a commercial website of a company selling all sorts of commercial explosives for cilvil usage.

On one page I found a description of some "explosive" free for sale because it's actually not an explosive even though it DOES make considerable damage.

The description went somewhat along the line that this stuff is some sort of putty mass that has to be activated with some liquid that has to be stirred in. After this the putty stuff is being filled into holes, cracks or whatever. It takes hours, maybe even days - but the mass is expanding with incedible force and thus breaks the matter without explosion.

I could think that if, say a shopkeeper has lost his keys to his shop he might try to enter via a backwall of his shop with this method :rolleyes:

Sounds absolutely perfect: Nothing goes BOOM!, no sounds, no flash, no nothing - only cracks that enlarge and weaken the structure until it topples or someone decides that the wall is weak enough to push through.

Anyone got an idea what sort of stuff said substance is and if it would be possible to homebrew this?

Well, when you DO test some, don't worry too much about posting pictures.......yawn <img border="0" title="" alt="[Wink]" src="wink.gif" /> as they won't be too exciting.

Sounds clever stuff, but I'd be curios to know how slowly it works and how contained it has to be.

[S. Toppholzer]

AS far as I remember it doesn't need more confinement than ANFO

[S. Toppholzer]

OK. I found <a href="http://www.technology-pool.com/kuba_1d.htm" target="_blank">something</a> - it doesn't say anything agout the contents, the page is German, the lady on top defiunately not and terribly ugly - but wtf.

Essentially it says:

Betonamit R is a detonation free explosive (great, huh :rolleyes: )
for silent, vibration-free working without loose rocks falling down (sheesh - i hate translating).
Available in powdered form.
Usable in closed rooms, outside, under water (!!) and everywhere where big machinery cannot be used.
The only thing necessary is filling the bore holes with Betonamit R.
max diameter of hole = 40 mm at a temperature of less than 25°C.
If ambient temp is higher than 25°C a diameter of up to 35 cm may be chosen.
Follows a description of how to mix that stuff. It also says that it is waterthat the powder needs to be mixed with. The water shouldn't be warmer than 20°C. Recommended percentage of water in the mixture should be 20 to 23 per cent at most.
After an hour f intense stirring the stuff is being filled into the holes.

The final paragraph reads:
"Betonamit R reaches an expansion pressure of more than 4,000 tons per square meter within less than 10 hours.
After this its power is constantly rising and it reaches a peak of 10,000 tons per square meter after a period of about two days. Usually an expansion pressure of 3,000 tons per square meter is more than sufficient for moving work."

Finally it says that this stuff is also available as a putty.

On the safety page they say BETONAMIT is mostly CaO.

[S. Toppholzer]

true... But that alone wouldn't allow me to make something like that myself, would it?

Wieso kann ich die Dateien, die Du auf Deiner Seite anbietest nicht runterladen? Mach' ich was falsch?

[wantsomfet]

Wahrscheinlich.

Nearly all files are up, which do you want?

NBK2000 has already posted a topic about this stuff a while ago. As far as I remember he had a fair bit of information about it (as NBK normaly does)

Do you remember the name of that topic NBK2000?

the problem I have seems being related to the server your files ar on. Everytime I click the link for downloading a file the same download page is popping up again and again.

I hope I am not asking too much here....

btw, do you know where to get PMJB Vol. 3?
The file on the forum server is damaged - as are the split files of it. I tried downloading these a couple of times but it doesn't work.

[wantsomfet]

OK i tried myself & it works fine...

LEFTCLICK THE LINK ON MY PAGE. A NEW PAGE OPENS WITH THE LINK... AGAIN LEFTCLICK IT! Download starts... No problem for me (IE6)

Chemische Kampstoffe & Gifte - offline & i didn't find it on my harddisk...
No idea where to find PMJB3, i have it but i have no broadband & also i think it's not worth it to download.

Back on topic.... <img border="0" title="" alt="[Wink]" src="wink.gif" />

Well, if it's mainly CaO it should heat up whilst adding water, leaving Ca(OH)2, this normally absorbs CO2 from the air, reacting to CaCO3 and water. But I doubt this would cause a volume expansion.

Here you go boys and girls:

Enjoy:)

Man...I just checked out that archive site and saw how funky the icons are! <img border="0" title="" alt="[Eek!]" src="eek.gif" />

It's always a hoot for me to see something I've posted in the past dredged up in relation to a current topic. I'm almost (though not quite <img border="0" title="" alt="[Wink]" src="wink.gif" /> ) cocky enough to say "There's nothing new under the sun". :D

Though (again) a search should have answered the question in the first place. Ah well...

I believe the stuff is a mix of lime and keishliguer (SP?). The water is absorbed the K, and the lime reacts to heat the water, causing it to expand. And water is (practically) incompressible, thus the containing rock or concrete must yield to the expansion.

Perhaps you could get a copy of the MSDS (if available) from the manufacturer.
