摘　　要：为提升混凝土结构耐久性能,在特定环境下必须采用有效地防腐蚀附加措施。其中硅烷浸渍技术作为提高混凝土耐久性方法之一,其应用日益广泛。本研究针对硅烷膏体浸渍对混凝土防水防蚀等方面保护作用,系统研究了硅烷膏体浸渍普通混凝土和海工混凝土后浸渍深度、吸水率、氯化物吸收量降低率、抗碱性能等方面性能。结果表明:硅烷膏体浸渍后形成一定厚度保护膜,有效地降低混凝土的吸水率和吸收氯化物能力,且涂覆硅烷膏体后混凝土抗碱性能也得到切实的提高。For promoting the durability of concrete structure,adopt some available antisepsis messure additional.Thereinto,as one of the methods to promote the durability of concrete,the application of silane impregnate tectnic are increasingly wide.Aiming at the protect function to concrete at waterproof and antisepsis by silane cream impregnating,we investigated the capability of the ordinarily concrete and marine concrete at deeping depth,water uptake,the absorption value reduce rate of chlorid and also alkali-resistance.The result showed that the concrete formed a thickness protection film by silane cream impregnating,the film could reduce the waterproof and chlorid absorption value of concrete,and it improved the alkali-resistance of concrete.
