By 'internal frost destruction' is meant damage caused inside concrete that is moisture insulated from the surroundings, i.e. when no moisture exchange with the surroundings is possible during freeze-thaw.

The aim should be reached by experimental work at which different parameters, that are supposed to influence destruction, such as concrete quality, moisture content, freezing rate, and duration of freezing temperature were varied independently of each other. The effect of these parameters on formation of ice, and on the behaviour of the concrete during freeze-thaw should be monitored.
