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 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.
