Cant see that working because of the curved hull required.

Not convinced it would work for a barge either, hard to

http://www.concreteships.org/ships/ww2/

I wasnt talking about concrete ships, of course those have been dont.
I was talking about push up concrete slabs for walls, can't see that
working for a normal ship or even a barge for the reason I stated.

But with 20/20 hindsight when not so early in the morning,
he may have been talking about YTong concrete that floats.
Not convinced about that either because those blocks are
autoclaved and its hard to see how you would make a
viable boat out of concrete blocks. The mortar between
block doesnt glue the blocks together, its actually just
a way of bedding the edges so they dont rock or leak.

I suppose I might be able to find a picture but I know a core drilled
piece from a Ytong wall floated in my pool. This **** feels like white
pine.

Sure, but its not feasible to do a boat like that. Its too big to autoclave
and you can't make boats out of even concrete blocks that float.

No its not, YTong concrete is autoclaved, ferro

you just need a big enough kiln. The panels I was looking at were 8x16
feet. That could have been a 16' boat.

Not enough would build a boat that way to warrant doing that.

Nope, because the boat is much thicker.

These were 16' x 8' x 8" thick panels and I bet they were not cooking
them one at a time.
Stuffing that 16' boat in that kiln would be trivial.

Sure, but the economics of a 16' boat occupying
the whole thing with just 2 panels is much worse
and non viable.

Stuffing that 16' boat in that kiln would be trivial.

Yes but the economics isnt. And a 16' boat isnt much of a boat.

I was thinking of some sort of molding technique using shotcrete or
gunite. The autoclave part might be technically if not economically
feasible. At least it wouldn't be as nasty as fiberglass with a chopper.

There are some very large industrial autoclaves. You wouldn't be doing a
Queen Mary but smaller pleasure craft like drift boats could be done.
That's where the economics breaks down. Glass is nasty but it's fast.

You cpuld park a transport truck in many autoclaves.

The Boeing autoclave for the dreamniner components is 30 x 75 feet. -
total volume over 82000 cu ft. - Built by ASC Process Systems.

Runs at 450F and about 150psi.

Hutachi built another one in Japan for Boing that is 98.5 feet long
and 30 feet in diiameter./ Could make a pretty good sized hull in
either of those!!

Quite a few ferrocrete yachts - and the tall ship training ship
Fallmouth is ferrocrete. Lots of ferrocrete "samson" lobster boats in
the carribean as well. - and John Samson's famous "stormstrutter"
which he sailed extensively from about 1970 'till his death in 2009 -
and I believe the family still owns and sails it. (a 48 ft Ketch) Lots
of Ferrocrete boats were built from Samson plans - and quite a few
actually ended up in the water and sailing.
