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.
