Numerical Modelling of Heat Transport in Freezing Mortars with an External Liquid Reservoir

Abstract Several studies indicate that the temperature distribution in concrete may affect extent of frost scaling. This study presents a numerical model describes thermal response freezing mortars presence an external liquid reservoir, where is either pure water or 3% sodium chloride solution. The phase transformation supercooled modelled two stages: quick freezing, when starts to form crystals and slow freezing. developed parts. In part I, focus modelling liquid, therefore non-porous body with reservoir validated. II, I further for porous containing different phases, i.e., unfrozen ice, pores. A comparison simulated experimentally measured distributions shows good agreement.
