TAPP Portland Composite Cement CEM II/B-M (S-D) 52,5 N – Duracrete ® basic is a hydraulic
binder according EN 197-1.
The main ingredients of TAPP CEM II/B-M (S-D) 52,5 N – Duracrete ® basic are Portland Cement
clinker, blastfurnace slag and silica fume of chosen quality. As solidification modulatorcalcium sulp-
hate is added.
By stringent production monitoring during the complete production procedure a uniform quality on
a high level is maintained.
TAPP Portland Composite Cement CEM II/B-M (S-D) 52,5 N – Duracrete ® basic combines by the
balanced combination of Portland Cement clinker, blastfurnace slag and chosen silica fume qualities
the special properties of silica fume cement with the advantages of foundry cement. The concretes
produced with this cement form an extra dense microstructure with high final strength and very good
TAPP CEM II/B-M (S-D) 52,5 N – Duracrete ® basic is low on chromates. By addition of a chromate
reducer the contents of water soluble chromium VI < 2 ppm.
TAPP Portland Composite Cement CEM II/B-M (S-D) 52,5 N – Duracrete ® basic can be used for
the production of all concretes according DIN EN 206-1/DIN 1045-2.
Mainly the TAPP Portland Composite Cement CEM II/B-M (S-D) 52,5 N – Duracrete ® basic is
used for concretes, for which high early and final strengths up to a strength class of C100/115 must
be reached and/or high requirements for tightness and constancies of the concretes are set.
A preferred field of application for TAPP Portland Composite Cement CEM II/B-M (S-D) 52,5 N –
Duracrete ® basic constitute the high performance concretes for various areas (e.g. high building and
bridge building, urban hydraulic engineering, mining).
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. The permissible
amount of fly ash according DIN EN 450 is for this cement limited to 15 % of the cement weight.
The addition of silica fume as additive is excluded.
For the production of reinforced concrete according DIN 1045-1 with direct bond as concrete
additives only fly ash and silica fume or inert powdered minerals according DIN EN 12620 and
pigments with proved inoffensiveness for tensing steel may be used.
A initial test according DIN EN 206-1/DIN 1045-2 is necessary at addition of concrete admixtures.
The addition of concrete admixtures is permissible according DIN EN206-1/DIN 1045-2, when these
conform to the appropriate standards resp. has a general building authority approval and is used
according to the conditions as stated in the approval.
