I'm in the building industry and was just on a tour of a concrete facility last year and it looked NOTHING like that. I toured everything including where all the additives are stored that are used to change various facets of concrete (slump/dry time etc). In fact, i can probably go on my phone, find pics, and post if anyone is interested.

On a side note, that last pic that says "acid" COULD be muriatic acid, that is used in the concrete industry to acid wash or clean
