UltraPozz: Ultrafine Pumice Pozzolan

UltraPozz (Ultrafine 3-Micron Pozzolan)

Pozzolans are a class of supplemental cementitious materials (SCMs) that supercharge concrete performance. Pumice, in particular, is an excellent pozzolan. Used at a 15 to 20% replacement rate for Portland cement, the finely ground pumice pozzolan works to drastically reduce, even eliminate, by-product CH by coverting it to CSH. More CSH means more binder. That means more density in the concrete matrix, more long-term strength, less permeability (becomes highly resistant to chemical attacks and freeze-thaw-process damage), reduced heat of hydration cracking, and flatlined alkali silica reaction. All that adds up to high-performance concrete durability.

Typical Applications: UltraPozz is a bright, highly-effective natural pozzolan used in high-end precast concrete products like glass fiber reinforced concrete (GFRC) panels and other architectural accent pieces. Also used in ultrafine cementitious grouts.
