Inspired by the natural, twisting patterns of a lobster shell, Australian researchers say they have found a way, using 3D printing technology, to improve the strength of concrete for use in complex architecture.
Reinforced with steel fibres, the concrete becomes more durable when set in a pattern that copies a lobster shell, according to a new study from Melbourne’s RMIT University.
Rather than use a mould, the process involves depositing layers of concrete one on top of the other, directed from a computer program using 3D printing technology.

Roam if you want to and dance this mess around with 52 girls.
No rebar; they used volcanic ash. We can use fly ash.
Interesting wiki article!

How do you know they were cold joints? Didn’t sound like that to me.
Going by the results, even with this so called ‘cold joint’ process the end result was stronger.
Did they do a compression test?
A cold joint is concrete poured/placed to that already there, even if not cured at any stage.
Another way for a few of the very rich to try to own all concrete pouring jobs. Those robotic pumps are going to have some shock and awe price tags on them.
Always tried to get my daughter’s band director to play Rock Lobster - would have been a great marching band tune (BTW that’s one of the ways you know you’re getting old - when the marching band is playing music you liked as a kid for the halftime show).
the girls are easy on the eyes even if Red does play for the other side
sure, why not
My understanding is that Rebar makes concrete more resilient and tougher, while limiting its lifespan.
