Researchers aiming to make buildings much safer during natural disasters have revealed 3D-printed concrete that gets stronger when cracked.
As the old saying goes, what doesnt kill you makes you stronger, and when it comes to the latest concrete design, that couldnt be closer to the truth.
In a paper published to the journal Advanced Materials, a team from Purdue University in the US revealed an advanced 3D-printed concrete paste designed to actually become stronger when it starts to crack.
The new material drew inspiration from nature, specifically the shell of arthropods such as lobsters and beetles that get tougher under pressure. In doing so, the creators hope that the concrete paste could be used to make houses and buildings stronger during wildfires and earthquakes.
With a built-in weakness, the concrete would be able to control how damage spreads between the printed layers of the material, similar to trying to break a bundle of uncooked spaghetti versus a single piece.

Interesting .... but definitely breaks the “KISS” principal (Keep It Simple, Stupid!). I wouldn’t invest in this being a new technology to save the world.
I saw a show a few months ago and Our Military was making Instabarracks. Basically just spraying it right on the floor. I wish I’d DVR’ed it.
Why all three (or probably more) government agencies need to be doing the same work. Combine the work and eliminate the needless overhead
Truly, this is the perfect example of the American tax payer's pockets being picked.
And when you step on the cracks, your mom’s back gets stronger.
“...that get tougher under pressure...”

Not a new concept, even to construction. The arch is thousands of years old.
Just like a Democrat presidential candidate..................
AND leaks just like a democratic candidate.
