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.

    I of course would if told that’s a problem. The failure, as I see it, is that “chicks” only came into my lexicon via women. If they’re using the term, how am I being offensive?

    This feels like manufactured grievance. I present an excerpt from an email I received from the woman who got me into the rave scene many moons ago:

    damn [Powderhorn]! you’re braver than i shall ever be. remember to follow the sunset- not the sunrise. it can only blind you and lead you where only the teachers and preachers want you to be. always take that shadowed path… that is where you will find happiness. not many find it there, but you are one of those few - i know. whether it be early in the morning, downtown in a strange place with some bizzare chick … good traveling. this is your life. i am so jealous that you are taking it upon yourself to be your own life. someday i will be that brave… i wish you all the luck in the world… your friend forever

    Now, we can play this game that I hate women, but it’s not going to have a lot of legs.

    • Now, we can play this game that I hate women, but it’s not going to have a lot of legs.

      I literally never said that and don’t even know where this came from. Please stop escalating beyond what I have said

      Could be a few reasons. Internalized misogyny is a thing. Maybe they grew up around it and didn’t know the connotations. The more likely thing is that when it entered you lexicon it was more acceptable. Times change, culture changes, language changes.

      If nothing else, you clearly have a group around you that tolerates the use. And if that works for them, that’s fine. The folks here don’t know you, though. We only have your interactions on here to guide us. Getting defensive about using terms like this paints a picture, however untrue, that you don’t respect women and don’t care to listen to outside perspectives.

        I mean, to me this is blown way out of proportion. It’s akin to saying “‘hot dog’ is offensive; you need to say ‘frankfurter.’”

        The amount of effort going into proving my misogyny for using a common term is just … wow.

        • OK, I have said this multiple times and you don’t seem to be listening.

          I literally did not say you were a misogynist. I never said you hate women. I stated that I did not think that in multiple ways. I said you are using an outdated term and people who are misogynists use it. I did so in the hope that you would at least be more cautious in your use.

          It’s akin to saying “‘hot dog’ is offensive; you need to say ‘frankfurter.’”

          It’s not though. It’s akin to using the G slur when you mean got ripped off. It is an outdated slang term that a whole lot of people find offensive. Even if the people around you have not, the greater population of people have moved the fuck on.

          Clearly you think this an attack on you (it’s not, for the record), so I am done. I’m done having the slightest critique escalated to an attack on your character. Honestly, I’m probably done with you altogether. This is not the first time you have had multiple people tell you something only to you stick your fingers in your ears and say “nuh-uh, my personal experience trumps all” even after being provided evidence of a world view beyond yours.

          So yeah, have a good one.
