aerated concrete is nothing new....but I cann't tell if it's an icf type system or just rehashed tilt-up concrete panels.

[leeman]

Old stuff ...

aah well...no it's not aerated turd.

What the fuck are you talking about then?

bah it was looking all funny and biodegradable, solid while being light and protecting from heat/cold.

I was like "hey it's cool".

And you guys pioneered working with volcanic stone?

well they look dutch at first sight but I was truely wondering why nobody changed building material...I mean concrete is always concrete, bricks didn't changed and stuff...it's all so annoying

Anybody want to know what the additive that is used in concrete to "aerate" it or produce the millions of tiny bubbles? Technically its called a liquid air entraining agent. But what would the layman call it?

That bubble making shit?

yes, but not the right answer

[Bill]

yes, but not the right answer

I always get confused when between aerated concrete and light weight concrete.....so I give up

mini air concrete-aerating-monkeys ?

liquid soap.

[Flumper Barflusterbutt]

Modern day concrete is air entrained using not fat, but a soap that can produce a bubble of a given size in an alkaline environment. Most air-entrained concrete contains about 4 to 7 percent air by total volume of concrete.

how the hell do you know that ? so you put soap in the concrete and it makes bubbles...so if you put a lot of soap it makes soapy cement when it rains ?

dude, i know way too much about concrete.

Actually, the millions of tiny trapped air bubbles help to make the concrete stronger against damage from freeze/thaw cycles. Now, the weird thing is that you want "entrained" air, or trapped bubbles that do not touch each other. But, you do not want "entrapped" air, which is basically just air voids in the concrete because it was not properly placed (with virbrators, etc.) Entrapped air will hurt the strength, while entrained air increases the strength.

concrete vibrators are $$$

interesting. maybe it's related to the tensioactives of the soap who keeps water together creating some kind of complex thing.

so that we are at the concrete stuff, if I put someone into concrete then drop it into sea I bet that even csi las-vegas/miami/new-york toghether won't find him
