POZZOLAN

In Portland cement, 10 to 25% of the cement can be replaced by BRZ™ clinopilolite zeolite, which is a type N pozzolan that produces a light-weight cement. It can be applied by adding it to the concrete at the batch plant, or added at the cement plant after the kiln as minus 6 inch rock directly to the inter-grind circuit. The advantage of the latter method is that it does not go through the kiln, which substantially reduces fuel cost and carbon dioxide generation.

BRZ™ increases compressive strength, reduces chloride permeability, decreases alkali-silica reactivity, resists sulfate and acid attack, and improves chemical resistance. BRZ™ can be used instead of fly ash, which contains heavy metals and is hazardous to humans.
