I love seeing my countrymen coming up with dumb ideas that work, very Australian.

DragonTypeWyvern ,

They definitely spilled it while testing something else.

And so it was, the scent of coffee through concrete will influence coffee drinking by 500%.

RegularGoose , to technology in Scientists strengthen concrete by 30 percent with used coffee grounds

This is one of those things I’d never think to try, but am still surprised that no one else did decades ago.

Gork , to technology in Scientists strengthen concrete by 30 percent with used coffee grounds

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 wouldn’t mind trying out Threads…

If the sign up process wasn’t so difficult. It shouldn’t be a country club.

I hate how tied it is to Instagram.

I really like the design of the login page, will I try the service? Nope.

but the new features coming out could entice those early adopters to take a peek and become active users.

Howdya do that font/markup? Is that code

This is the best summary I could come up with:


After announcing that its Twitter competitor would be accessible from browsers earlier this week, Meta’s rollout is finally underway.

Instagram head Adam Mosseri confirmed Thursday the update is now live for all users.

Though it was possible to manually navigate to a specific user’s profile, people have been unable to browse their feeds, post, reply or even log in to their accounts from browsers.

Now that the web version is finally live, it will be interesting to see which of the many “missing” features Threads will get next.

Mosseri has said he’s reluctant to add another inbox to user’s lives, though he recently raised the possibility of incorporating Instagram DMs into the Threads experience.

But he did confirm that post-editing features are in the works, so at least Threads users won’t have to wait more than a decade for an edit button.

Not surprised it’s a Melbourne university researching this.

Knowing what little I know about Australia, shouldn’t it be reinforced with either beer or squashed cane toads?

Rubanski ,

Squashed cane toad experiments are incoming

I only use the finest Portland Arabica for my concrete needs.

Only opus caementicium for my buildings. I want them to last 2000 years.

Mmmmm nothing like the smell of freshly roasted concrete to start your day.

Elderos ,

the smell of old used roasted concrete!

I bigly approve of this.

oxford, can we approve the word “bigly”? thanks

scottyjoe9 ,

It was right there all along. 🤔

In a few years we will all be injecting blivcheche and sunlilit while sipping on our covfefe.

Who will be laugthithing then ?

Despite the constant negative press

AbouBenAdhem , to technology in Scientists strengthen concrete by 30 percent with used coffee grounds

Can I also strengthen my coffee by adding a little concrete mix?

TropicalDingdong ,

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.

Selmafudd ,

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

Excrubulent ,
@Excrubulent@slrpnk.net avatar

Makes sense if you were working with strong acids. Bleach or baking soda might’ve had a similar effect.

Selmafudd ,

Was domestic so plenty of urine from blocked drains I guess

Excrubulent ,
@Excrubulent@slrpnk.net avatar

Ah, I see what you mean now by “dirty”.

SCB ,

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

This is the best summary I could come up with:


At the same time, we generate about 10 billion kilograms of used coffee grounds over the same span — coffee grounds which a team of researchers from RMIT University in Australia have discovered can be used as a silica substitute in the concrete production process that, in the proper proportions, yields a significantly stronger chemical bond than sand alone.

“The disposal of organic waste poses an environmental challenge as it emits large amounts of greenhouse gases including methane and carbon dioxide, which contribute to climate change,” lead author of the study, Dr Rajeev Roychand of RMIT’s School of Engineering, said in a recent release.

He notes that Australia alone produces 75 million kilograms of used coffee grounds each year, most of which ends up in landfills.

In order to make the grounds more compatible, the team experimented with pyrolyzing the materials at 350 and 500 degrees C, then substituting them in for sand in 5, 10, 15 and 20 percentages (by volume) for standard concrete mixtures.

“The concrete industry has the potential to contribute significantly to increasing the recycling of organic waste such as used coffee,” added study co-author Dr Shannon Kilmartin-Lynch, a Vice-Chancellor’s Indigenous Postdoctoral Research Fellow at RMIT.

"Our research is in the early stages, but these exciting findings offer an innovative way to greatly reduce the amount of organic waste that goes to landfill,” where its decomposition would generate large amounts of methane, a greenhouse gas 21 times more potent than carbon dioxide.
