The experiment of freeze-thaw,frost-salt and capillary absorption after different freeze-thaw injury was carried out to study the performance of the concrete with addition of silane emulsion.The result indicated that the concrete with certain amount of silane emulsion had a low anti-freeze performance,and the anti-freeze performance decreased with the dosage of silane emulsion increased.But he concrete with addition of silane emulsion had a good water resistance performance under different freeze-thaw environment.
