摘　　要：主要讨论了英国公路局出版的《路桥设计手册》(BD43/03)和我国交通部标准《公路工程混凝土结构防腐蚀技术规范》(JTG/TB07—01—2006)中的混凝土表面用有机硅渗透剂吸水率试验方法的差异。通过试验发现:空白试件水浸泡24h后基本吸水饱和,而硅烷浸渍试件水浸泡21d后仍处于吸水状态。建议对空白试件和硅烷浸渍试件的浸泡时间及其它试验步骤作适当修订。The differences of water absorption test method between'Design Manual for Roads and Bridges'(BD43/03) published by Highways Agency in the United Kingdom and standard of the Ministry of Transport of the People's Republic of China 'Specification for Deterioration Prevention of Highway Concrete Structures'(JTG/T B07—01—2006) were discussed.According to the test results,organosilicon-untreated concrete test cubes had absorbed water to saturation for 24 h,while organosilicon-treated test cubes were still absorbing water after 21 d.The author suggested that the immersed time for both untreated and treated test cubes,the test procedure or method should be modified appropriately.
