Scientists strengthen concrete by 30 percent with used coffee grounds::Researchers in Australia have found a new use for old coffee grounds: concrete doping!.
Can I also strengthen my coffee by adding a little concrete mix?
For science, go for it!
The lime that concrete is made of is alkaline, so if you’re very careful a little bit may simply neutralise the acid. Neutralised… I think it’s just chalk? Don’t do this though, it wouldn’t take much to mess it up and do serious damage to your insides. Plus idk if it’s actually just chalk. Also if you wash your hands with vinegar after a day working with cement it gets rid of the horrible dried out feeling and feels nice & creamy, because it neutralises the base.
This is funny because when I was a plumber after particularly dirty days I used to wash my hands with cement and I used to think that made my hands feel smooth
Makes sense if you were working with strong acids. Bleach or baking soda might’ve had a similar effect.
Was domestic so plenty of urine from blocked drains I guess
Ah, I see what you mean now by “dirty”.
Time to go write a cozy mystery where the murderer is poisoning people with tiny amounts of concrete in the coffee.
Asking the important questions here, we just find out, for science ofcourse
Can we call it cofcrete?
Covfefe
I bigly approve of this.
oxford, can we approve the word “bigly”? thanks
It was right there all along. 🤔
Despite the constant negative press
From a materials science perspective, a jump of 30% for a material that’s been well known for thousands of years seems unlikely.
Well, not really. They only mentioned compressive strength, so other important qualities and measures could be worse in unacceptable ways.
Or maybe it’s great. https://www.concretecentre.com/Specification/Innovative-concrete/Charcoal-Concrete.aspx
Two materials that have both been known for a long time.
I only use the finest Portland Arabica for my concrete needs.
Only opus caementicium for my buildings. I want them to last 2000 years.
Strange. Coffee has the opposite effect on me.

I like how the researchers thought, “hmm, I wonder what will happen if I mix my used coffee grounds with this batch of cement over here.”
This is unironically how most discoveries are made… Silly human curiosity
As long as it’s written down. Otherwise, you’re just a lunatic
Maybe they dropped old coffee grounds on their fresh concrete sidewalk while getting the trash out.
I always have these kinds of thoughts when reading articles like this.
On a serious note , I am pretty sure they find this stuff at the molecule level then match it to the closest item.
This is an area where AI might actually be really useful in the future. If that’s not already the case.
I love seeing my countrymen coming up with dumb ideas that work, very Australian.
that must be some shitty coffee
Mmmmm nothing like the smell of freshly roasted concrete to start your day.
This is one of those things I’d never think to try, but am still surprised that no one else did decades ago.
Gee, a controllable and fairly steady source of something that naturally generates methane. Better just bury it real quick because we’ve got fracking to do!
