The Hoover Dam concrete would cure in 125 years by conventional or natural methods. Crews, however, used some innovative engineering methods to hasten the process.
Nearly 600 miles of steel pipes woven through the concrete blocks significantly reduced the chemical heat from the setting for the concrete. Crews relied on 1,000-pound blocks of ice produced daily at the site’s ammonia-refrigeration plant.
Fun fact, concrete actually never stops curing, so I don’t know why they claim they could speed it up. Concrete has to set, dry and cure. You can speed up the first two, but not the last. You can make it reach design spec in say 7 days instead of 28, but it never stops curing.
Or you just didn’t know what the term meant and assumed and now for some odd reason want multiple industries to change what they’ve used for decades….?
Sure they’ll get right on that, or you could read a dictionary, there’s that option too.
not wet, but probably not nearly as dry, per se. also, fluctuations in temperature (specifically, mass of air in the packaging), as well as calibration issues on the devices- if you use two devices to measure… you’ll always get slightly off measurements.
However, I would sooner blame the scale itself as it doesn’t look like a scientific scale. So it’s likely not calibrated and will drift over time. Plenty of things could explain an 8g difference as measured by the average joe.
Weird that heavier packages are allowed a smaller tolerance ? Like a 198g package can be 28g under, but in the last row anything over 4.5kg needs to vary by less than 1%
If it weren’t obscenely expensive to do so, it would make sense for all scales to be calibrated to a NIST traceable standard, with periodic recalibrations at preset intervals.
Most kitchen scales could be easily calibrated with a measuring cup and water if they really wanted to do this. Just have a few included cups for 25,50,100ml of water and then fill them on the scale and tell it what the volume is.
That will easily get you within a gram of error for most common food weights.
So they package it wet? If the weight went down it means the pasta was wetter at time of boxing.
yeah, but that doesnt mean much. the hoover damn is still drying.
So is all the water it’s holding back 😱
Would have doesn’t mean is. Source

Opinion: If it never stops curing, then maybe we should stop using that term.
What other term would we use? Lost of items never fully “cure” I’m struggling to think of something that does. Paint doesn’t, nail polish doesn’t.
It’s why it has to dry and set first. Concrete is completely usable after it’s set, it just gets stronger as it cures.
Why do you think paint says not to wash the wall for a month after, the paint still has to cure after drying and setting.
I’m saying, come up with another term.

Or we could stop pedantic arguments like this by having a separate name for the two similar but different chemical reactions.

It’s far more likely that this is just weight variation which is allowable per the Food Safety and Inspection Service

If I’m reading table 2-9 right this package would be allowed to be under by 28.3g
Yeah that seems to be how it reads.

RH during packing 55%, RH in OPs house 25%
Just different conditions, even his neighbors house could have a different RH and different results.
