Natural Pozzolans

Natural Pozzolans are typically  produced by volcanic eruptions, consisting of high concentrations of amorphous (non-crystalline) silica and aluminum oxides, key ingredients for concrete enhancement

PozzSource controls one of the largest natural pozzolan deposits in the western US and is currently developing several more.
