Abstract
It is shown that the inability of water contained in pores to crystallize in situ leads to gradual and continuous redistribution of the adsorbate on cooling to below 0 degrees C. Frost damage occurs when the process cannot proceed because the amount of capillary water that is becoming unstable in unit time is greater than the flux. The established harmful effect of the intermediate-size pores, large sample dimensions, high degree of saturation and rapid cooling rate are to be expected. Correlation between nitrogen surface area and frost resistance of bricks was found to be good; this can also be explained by the theory.
