CEM II/A-LL 32.5 R
Composition:
TAPP Portland Limestone Cement CEM Il/A-LL 32,5 R is a hydraulic binder according EN 197-1.
The main ingredients of TAPP CEM Il/A-LL 32,5 R are Portland Cement clinker and a selected
limestone with high purity. Further calcium sulphate as congealment sabiliser is added.
By stringent production monitoring during the complete production procedure a uniform quality on
a high level is maintained.
Properties:
The advantages of TAPP CEM Il/A-LL 32,5 R are mainly in the area of fresh concrete.
The fresh concrete has a good adhesiveness, is ductile and thus is easier processable and pumpable.
The good water retention capability lowers the bleeding of the fresh concrete. This leads to an
improved surface development of exposed concrete surfaces.
TAPP CEM Il/A-LL 32,5 R is low on chromate. By addition of a chromate reducer the contents
of water soluble chromium VI < 2 ppm.
Application:
TAPP Portland Limestone Cement CEM Il/A-LL 32,5 R can be used for the production of all
concretes DIN EN 206-1/DIN 1045-2.
TAPP CEM Il/A-LL 32,5 R is also approved for concretes with high resistance against frost and
de-icing salts.
For TAPP CEM Il/A-LL 32,5 R the following fields of application unfold:
Ready-mix concrete industry
Concretes, which are fabricated with TAPP CEM Il/A-LL 32,5 R remain for a relative long period
well workable and concretion willing.
Screeds
Screed mortars fabricated with TAPP CEM Il/A-LL 32,5 R can be very well pumped and are
very concretion willing, well planable and don’t tend to separate water.
Concrete additives:
The addition of concrete additives is permitted according DIN EN 206-1/DIN 1045-2, if they conform
to the relevant regulations or a general technical approval is available. Concrete additives with
approval may only be used under the conditions as stated in the approval document.
For the production of pretensioned concrete with direct bond according DIN 1045-1 as concrete
additives only fly-ash and silica fume or inert powdered minerals according DIN EN 12620 and
pigments with proven harmlessness for pretensioning steel, may be used.
An initial test according DIN EN 206-1/DIN 1045-2 is necessary for the addition of concrete
additives.
Concrete admixtures:
The addition of concrete admixtures is permitted according DIN EN 206-1/DIN 1045-2, if they
conform to the relevant regulations or a general technical approval is available and when used
under the conditions as stated in the approval document.
An initial test according DIN EN 206-1/DIN 1045-2 is necessary for the addition of concrete
admixtures
Quality control:
TAPP Portland Limestone Cement CEM II/A-LL 32,5 R is subject to a self monitoring by our
in-house laboratories.
Delivery:
As bulk in silo trucks and bagged good in bags with 25 kg contents
Storing:
TAPP Portland Limestone Cement CEM II/A-LL 32,5 R must be dry stored and protected
against humidity.
