Experimental Study about the Influence of Silane Impregnation on the Durability of Airport Pavement Concrete in Aircraft Deicing Fluid Environment

Abstract

In order to study the influence of silane impregnation on the durability of airport pavement concrete in aircraft deicing fluid environment, corrosion resistance test, dynamic elastic modulus test, frost resistance test, and mechanical test (tensile strength) are adopted. The results show that (1) After 50 corrosion cycles, the surface of concrete without silane impregnation appears slight spalling, but the silane impregnation concrete does not, which indicates that silane impregnation effectively improves the corrosion resistance of concrete. (2) After the corrosion cycle and freeze-thaw cycle, the dynamic elastic modulus of the silane-impregnated concrete is nearly 1 / 4 higher than that of the untreated concrete, and the flexural strength is 19.88 % higher, proving that silane impregnation has a good enhancement effect on the durability of concrete.
