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