UHPC Bridge Deck Joint Filler BF

In many prefabricated concrete bridge constructions, the joints between the individual elements are filled
on site with a UHPC joint filler after the concrete elements have been installed. This creates a continuous concrete bridge deck.
Our BF joint filler systems have compressive strengths of 150 MPa - 220 MPa and flexural strengths of 14 MPa - 21 MPa.
The water to cementitious ratio is less than 0,22
Our BF System joint fillers can be processed on site with pan pot mixer, shaft mixer and horizontal mixer.
For very large sites with very large UHPC binder requirements we have mobile production plants for the binder and mobile mixing plants for the UHPC concrete. All plants are housed in containers and are therefore independent of weather conditions. With our mobile production plant for our UHPC joint filler systems, we are able to use local raw materials if suitable.

 

The joint filler BF systems can be used for all connections between adjacent box beams, next D beams, precast deck panels and beam haunch connections.
There is a wide range of concrete element connections. Each state in the USA and therefore DOT has its own specifications for these.

Fast - Faster - UHPC Rapid for new installation and repair

For very fast assembly in the taxiway of an airport
we have delivered a special UHPC (Ultra high
Performance Concrete) Cast.

Last Airport project:
There had to be laid cable protection pipes in the
area of ​​the taxiway. For this purpose, a slot of
20cm / 7,87in wide, 100cm / 39,37in deep and
100meters /109yd long in the existing concrete
floor had to be milled. For the filling of the slot
after the cable protection pipes had been laid,
we delivered a quick-hardening UHPC Rapid
Cast. The setting time of this special UHPC
is 2-3 hours, depending on the environmental
conditions. After this time it reaches a strength
above 20 MPa / 2900 psi. The final strength
after 48 hours is about 80 - 100 MPa /
1160 - 14500 psi.


Originally the UHPC Rapid product series
was developed about 20 years ago for wear
protection repairs in steel plants, power plants,
mining plants and cement plants.
Later, the UHPC Rapid was used not only as
a mortar but also as a cast and shotcrete. The
UHPC Rapid shotcrete was particularly used
in mining tunnels and the UHPC Rapid Cast
was used in the new lining and repair of
roadways, roads, storage areas and industrial
floors.

Meanwhile, it is also used as repair material
in airports, on highways and bridges.
