Try foamcrete

Easy to make bricks

Hempcrete is rising too

nope, going lava fused granite

Shotcrete is ok

Wth is that

New to me

Granite aint cheap

Lava, what kind of lava

well i got about 2 tons of it in my yard

You going to melt sand?

Hmm, good idea

use plasma cutter or laser cutter, weld granite sand between stones into a lava weld

But you would liquified

So your turning granite dust into plasma for welding granite together

u only need a fraction of an inch to weld

Yea ok

For real yes

Ive seen it before

Not what your talking about exactly

don't need water proofing afterwards

and the stone wall becomes like 1 stone piece afterwards

Never though of welding granite though

ever see those stones that look like they're perfectly cut into a wall, but they're several thousands of yrs old

Now we just need a robotic applicatiin technique

Yes

Inca

same principle

Aztec

Older

Olmec

some of them stones....are slag formed

in ingots

Yea butnit looked like they put softened stone and let it harden thats what i think they did

thats what lava is ....it's slag from the earth

Makes sense

So you could just use a form

Use some kjnd of dust for the medium

could, but would need a hell of alot better source of heat

Like granite dust in your case

Yea like lets just get a lava tap and hook it up to the magma
