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
