Abstract
The phase equilibrium in the Ca(NO3)2–H2O system at temperatures of 0 to –31°C is studied and the polytherm of calcium nitrate–solution ice crystallization is built, from which its melting capacity is calculated relative to ice under equilibrium conditions at different temperatures. The minimum effective temperature of using calcium nitrate as a deicing agent is determined experimentally. The corrosion activity of calcium nitrate solutions with respect to metals and alloys, as well as cement concrete, is investigated. It has been established that calcium nitrate does not attack metals, aircraft alloys, or cement concrete. According to the research results, it is concluded that anhydrous calcium nitrate can be recommended as a granular deicing agent for use on cement concrete and asphalt concrete runway pavements.
