硅烷是一种性能优异的渗透型浸渍剂，赋予混凝土表面憎水性，并保持呼吸透气功能。表面憎水性使混凝凝土吸水率极低，氯离子吸收效率降低90%以上，有效抑制海水的侵蚀，减缓因钢筋锈蚀和冻融循环对混凝土的破坏，保持混凝土的耐久性。
硅烷是一種性能優異的滲透型浸漬劑，賦予混凝土錶麵憎水性，併保持呼吸透氣功能。錶麵憎水性使混凝凝土吸水率極低，氯離子吸收效率降低90%以上，有效抑製海水的侵蝕，減緩因鋼觔鏽蝕和凍融循環對混凝土的破壞，保持混凝土的耐久性。

The silane is a kind of excellent penetrating impr-egnant, which makes concrete hydrophobic at surface and keeps breathable function. Surface hydrophobicity is deduced sharply in water absorption and the absorbing ef iciency of chloride ion is reduced by more than 90%, so that the seawater erosion is effectively restrained, the damage of concrete caused by the corrosion of steel bars and freeze-thaw cycle is relieved, the durability of concrete is kept.
