Who’s brilliant idea was this, SpongeBob SquarePants?

What makes concrete stronger is the amount of rebar you put in it.

Actually it’s the ratio of Portland cement, water and aggregate. With some additional additives such as Fibermesh strands.
I have been a supervisor at two different concrete batch plants for over 25 years, thank you.
To: Captain Peter Blood
Oh and yes rebar is fundamentally required in many cases, but the Romans didn’t have it.

"depositing layers of concrete one on top of the other"
Cold Joints. Not good.

To: Daniel Ramsey
The rebar doesn’t make cement stronger. It just keeps it in one piece after it cracks.

Any Compression Testing data of this 3D concrete for failure load comparison to conventual pours?

Interesting. I recall seeing a documentary many years ago that suggested the beehive honeycomb design would also be very structurally sound, requiring the use of less materials. Just use steel and concrete in a honeycomb formation and fill in the gaps with insulation.

Keep it wet while it’s curing.
That will make a big difference, too.

Everything you need to know about concrete!
It’s white
It’s hard and
It cracks.

Concrete is strong in the compression mode and weak in the tension mode. Steel is strong in the tension mode. By adding steel in the areas that are in tension it makes to composite product stronger.
