Polar Ice -- Colder Ice IS Stronger Ice -- Real Data Helps

NUKE PRO: Exposing Truth Anti-Nuclear Information and Resources, and Disaster Preparation Planning: http://nukeprofessional.blogspot.com/ It was fairly hard to find real data on Ice Strengths, especially as they relate to temperature.

I saw some pretty wild claims on some sites that “warm ice was 300 times weaker than cold ice”

As a material scientist, I thought this was worthy of some research.

I found this, with the very relevant chart of test points at 4 temps,  -3C, -10C, -20C, and -27C.

There are 2 important types of tests, Compressive, and Tensile.   Compressive is pushing on it.    Tensile is trying to pull it apart.  

Ice is way weaker in Tensile.   Also the saltier it is, the weaker it is (brineiness)

Bottom Line?
Ice is twice as strong at -27C than it is at -3C
