Outside of flood zones, I have done a few poured-concrete basement foundations. Poured walls in this area are typically 10 inches thick with rebar 2 feet on-center, so they have much more lateral strength than a typical block foundation. When walls are tall, pouring is much faster than using block.

Research suggests if the mineral is in the stone aggregate and mixed with concrete it could have a devastating effect. Over time, air and water seep into the pourous concrete causing the pyrrhotite to swell and expand. It lead to the cracks, pushing the house up and eventually could lead to the failure of the foundation.
