This study investigated the durability performance of concrete to which Polydimethylsiloxane (PDMS) was applied for penetrating water repellency. As the results of study, From test of the resistance to chloride ion penetration, superior salt-resistance was shown in comparison to plain concrete, by the application of PDMS. Experimental results of SM and IM showed more than twofold improved salt-resistance compared to plain concrete.
