The lowest temperature ever recorded was -81.4 °F, the highest +113 °F. Also, severe fluctuations in temperature can occur within only a few hours. It can feel like spring one day and like heavy winter the next. It is an understatement to say that this isn’t an easy environment for materials when it comes to civil engineering.
Testing to separate the wheat from the chaff.
In Canada, the suitability of materials for these extreme conditions is tested by the internationally recognized organization ASTM. FILCOTEN® also underwent this testing. “The testing assesses the resilience of materials to drastic changes in temperature,” Kastriot Malci, Technical Support Manager at Hydro BG, the BG subsidiary in North America based in Montreal, explains.
Extreme cooling and heating – 300 times in five hours.
Over a period of several hours the material is cooled down from 39.2 °F to -63 °F, before being heated from -63 °F to 39.2 °F – a temperature difference of more than 100 °F. ASTM’s independent engineers performed this procedure on FILCOTEN® more than 300 times within a period of five hours. The result speaks for itself: The FILCOTEN® partschanged their shape by an average of 0.3 % – hardly any change in shape at all. Furthermore, the average expansion was no more than 0.01 mm.
The testing engineers could not determine any cracks or damage to the material, either. Following 300 cycles, the samples were still perfectly intact without loss of material. This is where normal concrete suffers significant frost damage.
Malci is satisfied: “We are now 100 % sure that FILCOTEN® has absolutely no problems with rapid temperature fluctuations”. The ASTM engineers were especially ambitious when it came to testing the material from Austria. “They wanted to challenge the Austrians’ precision, but FILCOTEN® passed the test with flying colors.”
If you make it in Canada, you can make it anywhere.
Once again, this result shows that the FILCOTEN® material is way ahead of its competition. One might almost think it was overqualified for European conditions. However, the climate can be unpredictable anywhere. Therefore, it won’t harm to use a product that proved its worth in Canada.
