混凝土材料用作氚处理设施的隔墙。掌握混凝土墙中氚的行为对于辐射安全非常重要。本研究认为，与多孔吸附材料一样，混凝土材料的表面水由物理吸附水、化学吸附水和结构水组成。本研究中观察到的物理和化学吸附等温线的吸附容量表明，水泥浆体上的水吸附量是活性氧化铝或分子筛5A（MS-5A）表面吸附量的四分之一。这说明混凝土很容易被氚化水污染。
The concrete materials are used as the partition wall of the tritium handling facilities. It is important to grasp the tritium behavior in the concrete wall for radiation safety. It is considered in this study that the surface water on the concrete materials consists of physically adsorbed water, chemically adsorbed water and structural water as in the case of porous adsorption materials. The adsorption capacity due to physically and chemically adsorption isotherms observed in this study shows that the amount of water adsorption on the cement paste is a quarter of the amount adsorbed onto the surface of activated alumina or molecular sieves 5A (MS-5A). It shows that concrete is easily contaminated with tritiated water.
