摘要
进行了掺硅烷乳液制备整体防水混凝土的水冻、盐冻以及不同冻融损伤后的毛细吸水试验。结果表明,在混凝土拌合料中掺加一定量的硅烷乳液,使混凝土的抗冻性降低,并且随着硅烷掺量增加,混凝土的抗冻性能变差。但是在不同的冻融损伤条件下,掺硅烷制备整体防水混凝土仍具有较好的抵抗水分侵入性能。
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.
