UHPC machine beds, frames and foundation for a high-tech machines

Various UHPC binder systems have been used by us for more than 25 years worldwide for different
industries such as cement plants, power plants, iron, steel and mining industries. Developed and produced as wear protection and industrial flooring or as foundations and anchoring systems for the offshore and engineering industries.

UHPC concretes are very suitable for machine beds and frames of any kind of high-precision drilling machines, grinding and milling machines.

The advantages
A very high surface quality. Due to the accuracy of the moulds, subsequent machining can often be dispensed with. With UHPC, an accuracy of 0.1 mm/0.004 in from the mould can be achieved when using suitable moulds. The accuracy can be increased to 0.005 mm/0.0002 in by grinding.
Very high pressure resistance
Very good stiffness and dimensional stability

Very good damping properties compared to cast steel constructions and same vibration damping as natural stone. The vibration damping of UHPC concretes is approx. 70 - 80% faster than standard cast steel constructions. Higher precision with faster processing speed.


Thermal properties:
Applicable up to 450°C/840°F without loss of engineering properties and dimensional stability.
High thermal shock resistance
Inertia during heat transfer
Low thermal expansion
Non-flammable


Very good flowability.
High integration capability. All types and sizes of anchors, pins, threaded sleeves, structural steel elements
and pipes can be cast without problems.
Extreme adhesion to cast-in fasteners and anchor elements.
Very high corrosion resistance
Due to the high strength development, material thicknesses and material weights can be calculated significantly lower.
UHPC castings can be removed from the mould within 24 hours and reach more than 70% of their final strength after 48 hours.
Faster delivery times
Drastically reduced costs
Elements made of UHPC can be recycled and reused like normal construction waste.
Due to the low energy consumption and low CO2 impact, the production is much more environmentally friendly than cast, steel and reactive resin concrete.


Technical data for UHPC Cast products

Density 2400 - 2900 kg/m3 / 168 - 181 lb/ft3
Compressive strength after 2 days 100 - 120 MPa / 14500 - 17500 psi
Compressive strength after 28 days 140 - 250 MPa / 20300 - 36200 psi

Applications
UHPC is suitable
for foundations, beds and frame parts of highly dynamic machine tools
for foundations of highly loaded machines, e.g. engines, generators, turbines, etc.
for foundations in the paper, wood, printing and textile industries
