    A silane-and-siloxane-based-surface penetrant with excellent early performance characteristics has been developed. It consists mainly of silane, a monomer comprised of silicon molecules, and siloxane, a polymer. This silane-andsiloxane-based surface penetrant was subjected to exposure tests for up to 15 years under various environmental conditions. The water absorption prevention effect of the silane-and-siloxane-based surface penetrant was found to last 15 years or longer, and while in coastal areas, carbonation progresses as the moisture content of concrete decreases, this penetrant is highly likely to have potential for inhibiting rebar corrosion.
