SATECMACAL is
a liquid admixture with a milky appearance, which, added to the mixing
water replaces and improves the properties provided by lime addition in
manufacturing mortars with cement and lime, avoiding bleeding problems
that the presence of lime causes in this type of mortars, giving way to
efflorescences which are difficult to remove.
Due to its special
composition, based on tensoactives, synthetic resins and retarding compounds,
apart from its main action as platicising agent, it has an important secondary
action as retardant.
The mortars mixed
with SATECMACAL in the mixing water produce more plasticised masses
and, as a consequence, with better workability and application.
If desired and due
to its high plasticising power, it's possible, keeping the workability,
to reduce the amount of water used in mixing (reduction of the w/c rate),
thus getting mortars with a higher final resistance.
Due to its retarding
effect and as secondary function, the addition of SATECMACAL to
the mixing water for mortars, provides a retardant effect to setting,
thus allowing a longer application time for the mortar.
SATECMACAL improves
mortar adherence to brick and ceramics in brick tenders, facing of walls
with ceramic coatings or paving of floors. |
