The specifics in the screenshot are a bit “legendy,” but the concept is real. Sugar does impede the setting of concrete.
The last time this was posted, someone with more complex knowledge on the subject showed up with backing science that not only is this not true, but it until the mixture is around 10 percent sugar by weight, it has no noticable effect. So unless you’re carrying 400 lbs of sugar with you, the only thing you’d do is risk arrest.
And I quote: Beyond 0.06% use of sugar it is found that the both initial and final setting times drastically reduces.
and a ton is 2000 lbs and we need only 0.1% to 0.2% of the mass to be sugar to significantly reduce setting times and cause concrete to be prone to crumbling Or 2 to 4 lbs for those that can’t math.
So not far off in terms of sabotage but not precisely correct in terms of the exact effects produced.
But the lesson can be better generalized, altering things from the engineered specification can with only subtle actions make breaking changes.
Like the loading dock manager in the 1980s in Intel that cost them billions by opening the wafer containers and trying to count them… https://www.youtube.com/watch?v=NGFhc8R_uO4
