Abstract
Freezing starts when water molecules within the concrete pores reach their freezing temperature and begin to solidify. Conversely, thawing is the melting of the newly-formed ice molecules at high temperatures. This cycle of freezing and thawing leads to the deterioration of concrete. As water molecules solidify, unfrozen water pushes through the capillary pores. This motion leads to an increase in hydraulic pressure. As described by Darcy's Law, pressure is inversely related to area. Hence, as the area allotted for water decreases, pressure increases. This study was designed to assess the eects of sample size, rate of temperature variation, and air content on the hygro-thermo-mechanical behavior of concrete in response to F-T.
