| Container with liquid nitrogen |
High Performance Concrete is at extreme
fast temperature changes.
We casted ten UHPC concrete plates with a
thickness of 25 mm /1 inch. The plates were
dried for 48 hours at room temperature
(20°C / 68°F).
No reinforcement was used.
The plates were cooled down from about
+20°C/68°F room temperature in a container
with liquid nitrogen (-180°C/-292°F ).We waited until the plates were completely
cooled. All plates showed no cracking after
removing them from the nitrogen tank.
We immediately heated the plates with a
burner within 5 - 6 minutes to +250°C/482°F.
Even with this alternating load, there were no
cracks visible.
For the test we used a our standard UHPCCast material with quarz 1-3 mm sand as
aggregate.
