摘　　要：水是影响混凝土耐久性的关键因素，而憎水保护是减少混凝土内部水分的有效途径。通过毛细吸水试验，发现有机硅防护剂能显著降低混凝土的吸水性，最高可使混凝土48h的吸水量降低98％。试验还表明，有机硅防护剂的使用方式、使用量和使用部位对混凝土吸水性能均有不同程度的影响。The moisture is the key factor that affects the durability of concrete. Hydrophobic protection is an effective way to reduce the moisture in the concrete. Through capillary water absorption tests, it is found out that the organic silicon protective agent can significantly reduce the absorption of water in concrete. The decrease of absorption of water （48 h） can reach 98 percent. The methods, volume and position will lead to different results for the absorption of water.
