Is concrete hazardous waste? Is concrete a hazardous material?

I get the question on is concrete hazardous waste a lot, and while the answer seems pretty clear to me, for some reason, it keeps coming up.Let's take the question of is concrete a hazardous waste, or the hazardous nature of concrete, one step at a time. First, let's consider what is waste.

Aggregates

Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases, soil-cement, and in new concrete. After harvesting, aggregate is processed: crushed, screened, and washed to obtain proper cleanliness and gradation.
