Workability
At the top of the Workability section, there is, "Main article: Concrete slump test." I do not think that the concrete slump test article is the main article for workability.
This article only shows how to test *for* workability, and does not describe what workability is. Maybe in
That article could be edited with the definition of workability.
Ancient times: "Mayan concrete at the ruins of Uxmal (850-925 A.D.) is referenced in Incidents of Travel in the Yucatán by John L. Stephens."
Why is this section in ancient times when the Mayan buildings were made in anno domini??? What's weirder it that it continues then to before christ times.

Claim that concrete is the second most consumed substance
My concern is that the claim is made without any sources or without offering a list of other substances that is consumed less. I did some math and confirmed that more concrete is used per year than oil (numbers for oil consumption taken from here:
/info/en/?search=List_of_countries_by_oil_consumption) but without a comprehensive list of substances and their yearly usage, this feels more like conjecture at the moment.

The Sciencedirect EFA article cites a book by the
US Geological Survey[1] that gives GDP numbers for a wide range of mineral products. The statement could be changed to "second most consumed material from a mineral source", but I think the way it's written is fine and accurate enough to the data available at time of writing. The USGS is constantly putting out reports on material usage that are useful for this exact comparison, so you could look up a more recent edition to support or refute the claim made here.
