AESTHETIC CALUMEX - white alumina cement range for decorative mortars and concrete

1. CALIGHT 70 is an extreme white calcium
aluminate.
Production through sintering high quality
alumina and lime this cement is used in dry
mortars as straight binder or as an addition into
a white Portlandcement mix.
In the mix calcium sulfate can be added to
reduce shrinkage , accelerate drying and
increase the density.
The amount of lime released during hydration is
neglitibale making it suitable as binder for white
or colored floor levelers , white marble
adhesives and tile grouts.
The consistency and stability of its color makes
is easy to add pigments to obtain colored
concrete and mortars.
Key benefits;
√ extreme whiteness
√ ease of coloring
√ no effloresecenes
√ durable and sustainable color
√ high resistance in aggressive
enviroment
√ high early strength
√ improved abbressive resistance

2. CALUMEX is a calcium sulfo aluminate
cement.Through sintering high purity bauxite,
limestone and gypsum an extraordinary cement
clinker is produced giving special feautures.
Although not white but light buff colored
CALUMEX can be mixed with White
Portlandcement to obtain a light colored
cementious binder featuring;
√ fast set
√ rapid drying
√ high early,and sustainable strength
√ no efflorescence
√ easy use of pigments
√ durable color
√ reduced addition of polymer
√ ease in polishing
√ non shrink or curling
√ low permeability
CALUMEX WHITE is produced in the same way
as CALUMEX QUICK but special attention is
given to the selction of raw materials and
calcination and cooling of the clinker.
This clear cement is used on its own or is
added into a Portlandcement mix.It is mainly
used in production of dry mortars, renders
and flooring products, natural stone adhesives
and grouts, GRC, prefab concrete and in any
other application where aesthetics,color
consistency, quick-setting and high early
strength play a role.
Average test results*;
• begin of set 20 min.
• end of set 27 min.
• 6 hrs.compressive strength 30 Mpa
• 6 hrs. flexural strength 5,8 Mpa.
• shrinkage at 7 days 0,02 mm/m
CALUMEX SC-A is the latest development in our
advanced calcium aluminate technology.
The main phase formed is C12A7 ,the most
reactive phase in cement hydration.
It is used as an addition to Portlandcement,
giving an acceneration of set and an increase of
the early strength.In addition the shrinkage of
the binder is reduced to nearly cero.
Because of the high purity of raw materials
used and the manner in which the cement is
produced SC-A has a whiteness of > 82.
It is mainly used in dry-mortars, shotcrete,
incaptulating nuclear waste, road-repair,
artificial stone, prefab concrete and in any other
application where aesthetics,color consistency,
quick-setting and high early strength are of
importance.
