This is a very cool discovery, but it's not like "used cement" ends up in landfills today. Most cement ends up as concrete. Crushed concrete of various sizes

Most cement ends up as concrete.
Crushed concrete of various sizes is a valuable aggregate used as a cheaper alternative to crushed stone for road building etc.
In my area any time I see an ad selling crushed concrete it's gone by the time I ring. Perhaps because we have clay and sand soils around here there is a permanent shortage of such things.
- onthecanposting 2y agoIt's common practice here to take demolished concrete from a structure and pavement and use it as structural fill for new development. Sometimes on the same property. Some agencies will not allow contractors to haul it off as it has salvage value. Concrete rubble is also salvageable on the job site. Recycling would require transporting to a mill, crushing, separating, transporting to a furnace, and then the process described in the article starts.
