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.\u003c\/p\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cp\u003e\u003cspan\u003e\u003cstrong\u003eTypical Applications:\u003c\/strong\u003e UltraPozz is a\u003c\/span\u003e bright, highly-effective natural pozzolan used in high-end precast concrete products like glass fiber reinforced concrete (GFRC) panels and other architectural accent pieces.
