Apparently just a kilogram of sugar mixed into a ton of concrete will destroy the ability of it to actually function correctly as concrete. But I learned this here on Lemmy and have not checked the veracity of it, so take it with a pinch (handful?) of salt.
It’s accurate or close to it… Some concrete truck drivers will keep bottles of coke to pour in there in emergencies where they need to make sure it doesn’t set inside the truck.
You figure the cement trucks will pull up to a sugar table so that protesters can add a few bags of sugar to each one? That seems unlikely. It also seems unlikely that anyone could get enough sugar deep enough into any structural element to cause any real damage.

What happens to the spiked concrete? Can they add something else to counteract the sugar later?
I’m a sweets guys, so I’ll take it with a pinch of sugar, thanks.
From what I read you need about 1% of sugar to completely stop the process. Anything below will slow down the process, but it isn’t capable of stopping the process.
