Pozzolith 89
POZZOLITH 89 is a powerful plasticiser which
disperses and deflocculates cement particles while
delaying the hydration process, thereby retarding the
initial and final set. It can be used to improve workability
without the addition of extra water, or to allow
reductions in the free water content. Due to improved
dispersion of the cement particles the process of
hydration proceeds under the optimum conditions,
leading to improved strength characteristics with or
without reduction in free water.
POZZOLITH 89 can be used with all types of Portland
cement including sulphate resisting (Type V). For use
with other special cements, contact BASF Construction
Chemicals Representative.
POZZOLITH 89 should not be premixed with other
admixtures. If other admixtures are to be used in
concrete containing POZZOLITH 89, they must be
dispensed separately. If in doubt, consult BASF
Construction Chemicals representative.
