除冰液对机场道面混凝土的破坏机理研究
Research on Failure Mechanism of Deicing Fluid in Airport Pavement Concrete
摘要
Abstract
Aiming at the salt freezing damage phenomenon of the airport cement concrete road surface in China, this paper carried out the statistical analysis of the concrete scaling mass of different concentrations potassium acetate deicing fluid by the one side immersion freeze-thaw cycle test. Results showed that the salt freezing damage of concrete in low concentration of potassium acetate solution was the most serious. By exploring of potassium acetate solution freezing behavior and concrete solution absorption, it determined that the higher con-centration of potassium acetate, the larger solution of concrete inhaling and the faster the suction rate. It also proved that the lower freezing and expansion rate made the freezing time longer. The most severe salt freezing damage occurred in the low concentration solution due to the concrete solution suction ,suction rate and solution freezing expansion rate.关键词
