The concrete and cement sector has been trying to reduce its environmental impact for years through sustainable concrete mixtures or efficient designs.

Now, a research team at the University of Pennsylvania has combined both novel materials and a material-saving design, without compromising on strength and durability.

The project, called Diamanti, takes inspiration from nature and uses a robotic 3D printer to create complex, lattice-like patterns with a sustainable concrete mixture.

While most regular concrete absorbs carbon dioxide (up to 30% of its production emissions over its entire life cycle, according to some research), Diamanti’s enhanced concrete mixture absorbs 142% more carbon dioxide than conventional concrete mixes.

Its first design, a pedestrian bridge, uses 60% less material while retaining mechanical strength, says Masoud Akbarzadeh, an associate professor of architecture at the University of Pennsylvania and director of the lab that spearheaded the project.

      It would be pretty kickass if Sigourney Weaver did the ribbon cutting on the first installed bridge. She’d need to shave her head, though.

            True, but that is isn’t one most people think about from the originals. I think Aliens is the most remembered. To the point I think people forget the original is creeping horror and not action

                People around here shocked by the mention of pubes, uh? (even though I’m commenting on a scene of the movie they were talking about)
                How can I know if it was a community or instance mod, though? I want to be sure which to block so I don’t make the mistake of commenting on a puritan forum again.

              I was never a huge fan of the franchise, as I hate horror, but when you’re young, you want to fit in, so you hear “oh, it’s not at all like the first one” and think “well, worth a shot.” Also, I have a thing for chicks with extremely short hair, so there may be some confirmation bias in my memory.

                Do you always talk about women like this? Chicks? Definitely a way to show that you don’t respect them…

                  I don’t know … I picked up using the term from my ex-wife. That’s what she referred to women as.

                    Idc, in certain contexts said by certain people maybe it’s ok. But as a usual way to talk about women as “chicks” or also the widely used “females” is demeaning and is rooted in misogyny. I’d think language can be powerful and we should reflect upon why we use certain words and what that tells us about our underlying worldview.

                    Actually, given more time to think about it, I picked it up from the chick who took me to my first rave in 1997. So I actually have nearly 30 years (my 45-year-old ex still uses the term) of evidence that this is an acceptable term for women.

                    Maybe go clutch a different pearl if you’re here just to find outrage. It’s slang and neither vulgar nor demeaning. Wrong C-word to challenge for referring to women.
