Rehabilitation and restoration of historic constructions with UHPC - part 1

Obtaining historical constructions is an 

important task. Much has already been 
lost through time and war, few of which 
are important to obtain.

we could not produce original materials 
from different time periods, so we can 
not fulfill this part of the restoration of 
historical constructions.

But with UHPC Ultra High Performance 
Concrete, we are able to offer solutions 
to a wide range of problems in conserving, 
reconstructing and restoring historical 
constructions.

UHPC has many advantages for use

• It can look exactly like limestone, 
  sandstone or granite
• it can be just as hard as limestone, 
  sandstone or granite
• It can be made as stones in any 
  measure like limestone, sandstone or 
  granite
• It can take over any stone surface of 
  limestone, sandstone or granite
• It can copy extremely accurate copies 
  including traces of use in all the finer 
  points of limestone, sandstone or granite
• It can be made as a casting material or 
  as a mortar and processed as traditional 
  casting and mortar mass for limestone, 
  sandstone or granite
• It can be machined with traditional tools 
  depending on the desired hardness.
• It can have almost the same consistency 
  as plaster and can be processed as well. 
  For extremely high whiteness we added 
  Aalborg White cement to our UHPC binder, 
  the cement grade with the highest degree 
  of whiteness.
• UHPC can add ductility to modern plastic 
  or ceramic fibers, so the great strength 
  of the material movements of old buildings 
  can certainly go along without the cracks 
  becoming visible.
• UHPC is impermeable to water from an 
  average layer thickness of 10 mm.
• UHPC can also be processed under water 
  as cast or mortar
• However, it is extremely resistant to all 
  types of environmental influences
• It is extremely resistant to frost and de-icing 
  salt
• Wood and steel can be cast in UHPC, 
  re-stabilized, restored to their original 
  carrying capacity, and given very high 
  corrosion resistance for many decades

UHPC is not magic material it is based on a 
particular nanotechnology and the right recipe 
for the right mix, for the right aggregates, for the 
right material quality.

With UHPC we can mix almost anything, old 
minerals, old textiles, old wood, old hemp, old 
pigments, old ground rock meal - just about 
everything.
