For very fast assembly in the taxiway of an airportwe 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 environmentalconditions. 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 usedin 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.
