摘要：Icing pressure testing was conducted to investigate the icing pressure (Ip) of chloride-based deicers and discuss the relation between Ip and the freeze-thaw deterioration of concrete induced by chloride deicers. During the icing pressure test, when the solution transformed from the liquid to the solid phase, undercooling occurred, and the heat of the liquid-solid phase transformation was released. The Ip of chloride deicers and water reached a plateau near −30 °C. The stable Ip value of water was the highest of that of the chloride solutions followed by that of 3.5% NaCl; the Ip of 3.5% CaCl2 was slightly higher than that of 3.5% MgCl2. The concept of the Ip cumulative effect with time (S) was first proposed to determine the freeze-thaw destruction induced by chloride-based deicers. The durable life of the concrete exposed to chloride-based deicers decreased with the S of the deicers, and the mass loss of the concrete increased with the S of the deicers. © 2019 Elsevier Ltd
