摘　　要：文中以某医院项目为例,对施工前蒸压加气混凝土墙体材料的导热系数进行试验,阐述三种不同结构形式的墙体表面层含湿率、墙体导热系数,通过计算含湿率降低值及导热系数降低值,得出不同墙体在各个龄期下的含湿率、导热性能变化情况及关键影响因素,以期为类似墙体材料的选用提供参考。Taking a certain hospital project as an example,this article analyzes the thermal conductivity tests of pre-construction autoclaved aerated concrete wall materials,elaborates on the moisture content and thermal conductivity of three different structural forms of the wall surface layer.By calculating the reduced values of moisture content and thermal conductivity,the changes in moisture content and thermal conductivity of different walls at different ages and key influencing factors are obtained,To provide reference for the scientific selection of similarwall materials.
