Portland cement CEM I 52.5 R (fc)
TAPP CEM I 52,5 R (fc) – Fastcrete ® plus is a hydraulic binder according DIN EN 197-1.
Main ingredient for TAPP CEM I 52,5 R (fc) – Fastcrete® plus is Portland cement clinker.
As congealment stabiliser calcium sulphate is added to the cement.
By stringent production monitoring during the complete production procedure a uniform quality on a
high level is maintained.
TAPP CEM I 52,5 R (fc) – Fastcrete ® plus has the potential to develop very high early
strength in the concrete.
In comparison to normal Portland Cement the concrete hardening occurs
also at low temperatures considerably faster.
TAPP CEM I 52,5 R (fc) – Fastcrete® plus is low on chromate. By addition of a chromate
reducer the contents of water soluble chromium VI < 2 ppm.
TAPP CEM I 52,5 R (fc) – Fastcrete ® plus can be used for the production of all concretes
according DIN EN 206-1/DIN 1045-2.
TAPP CEM I 52,5 R (fc) – Fastcrete ® plus is suitable for concretes for which a very fast
strength development is needed. A preferred field of application of TAPP CEM I 52,5 R (fc) –
Fastcrete ® plus is the precast concrete industry. With the cement the stripping times can be
considerably reduced. Thereby the productivity of the component production and especially the
utilization of the formwork materials considerably increase even without heat treatment.
As the accelerating effect of TAPP CEM I 52,5 R (fc) – Fastcrete® plus also appears at
lower ambient temperatures the possibility exists at unaltered stripping times to reduce the heating
costs during the winter months.
By the use of TAPP CEM I 52,5 R (fc) – Fastcrete® plus in pretensioned concrete the
transformation times for the pretensioned concrete elements can be considerably shortened.
The addition of concrete additives is not recommended.
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 are used under
the conditions as stated in the approval document.
However the practical concrete recipe for the
safeguarding of the functionality of the system should be agreed with the application support team
An initial test according DIN EN 206-1/DIN 1045-2 in case of addition of concrete admixtures is
