UHPC concrete for precast production

UHPC concrete has many commercial as well as technical
advantages over standard concrete for the production of 
precast concrete elements.
More and more architects are specifying UHPC concrete 
as a standard material for their façade design. There are 
no design limits for façade constructions.
In recent years, we have developed UHPC binder systems 
that can be processed into lightweight concretes or 
insulating concretes, especially for façade construction.

- We produce UHPC materials with a strength of
   40 MPa to 240 MPa.
- Our UHPC materials reach 70% of their maximum
   nominal strength within 48 hours. Faster strength
   developments are possible on customer request.
- We only need sand, not gravel, to process UHPC
   concrete.
- With our UHPC Desert Sand Binder, desert sand
   can also be processed without any problems.
- All of our UHPC materials are self-compacting
   and need no or very little vibration.
- Our UHPC materials have extremely little to no pore
   development.
- The nanotechnology development of our UHPC
   binders enables extremely fine surface structures to
   be created.
- With the use of fibre reinforcement it is possible
   to create very thin structures of high strength.
- For prestressed elements, the pre-tensioning force
   of UHPC material can be chosen to be much higher
   due to their very high strength than standard concrete.
- Very good flow properties for casting complicated
   geometry and filigree surface structures.

Processing of UHPC binders
Only a shaft or pan pot mixer is required for
processing.
The UHPC binder is mixed with sand or desert
sand and a very small amount of water.
It is not necessary to add additives.
