Pyrrhotite and pyrite: the differences
Pyrrhotite is a mineral species composed of iron sulfide and is of a
bronze yellow color, blackening when exposed to air. When it crystallizes in blades, pyrrhotite can produce cracks in the concrete structures.
Pyrite is a mineral which is found in stone and produces sulfuric acid when it oxidizes upon contact with humidity and oxygen.
When this phenomenon occurs under foundations, it can cause
the heaving and cracking of the concrete slab.
