| 摘 要： | 分析建筑围护结构的热湿过程有着重要意义,而材料的物理性质是完成分析必不可少的参数。对中国常用多孔建筑材料而言,其湿物理性质并不完备。在20~25℃下,依据ISO和ASTM标准,通过平衡吸放湿实验、压力平板实验、蒸汽渗透实验、毛细吸水实验和真空饱和实验,对中国产B07级加气混凝土进行了测试,得到了包括等温吸放湿曲线、保水曲线、蒸汽渗透系数、液态水扩散系数、吸水系数、毛细饱和含湿量和真空饱和含湿量在内的所有湿物理性质。

| Abstract: | It is important to analyze the hygrothermal processes of building envelopes and the material properties are critical in the analysis.The hygric properties of the commonly used porous building materials in China are insufficient.Measurements on the B07-level autoclaved aerated concrete are carried out at 20~25 ℃ based on ISO and ASTM standards of static gravimetric tests,pressure plate tests,cup tests, capillary absorption tests and vacuum saturation tests.All the hygric properties have been obtained, including sorption isotherms,the water retention curve,the vapor permeability,the liquid diffusivity,the capillary absorption coefficient,as well as the capillary and vacuum saturated moisture content. |
