All of these changes depend, however, on how rapidly and how long the concrete is heated. As concrete is cooled from 1,000 degrees F it loses another 20 percent of the strength it had while it was hot. Concrete expands at a normal rate in temperatures up to 300 or 500 degrees F but at higher temperatures it shrinks at an even faster rate.
