尾矿微粉加气混凝土砌块的自保温性能研究

Insulation properties research of tailings powder aerated concrete block

通过对专用砂浆加气混凝土墙体、普通砂浆加气混凝土墙体及加气混凝土清水墙进行稳态热传递试验,测定出三种墙体的传热系数。结果表明在清水墙上采用专用砂浆界面抹3~5 mm厚,再铺设纤维网格布,最后用10 mm厚专用砂浆抹面的专用砂浆加气混凝土墙的传热系数值小于1.0 W/(m^2·K),满足相关规范要求。

Determine the heat transfer coefficient of the walls of the special mortar aerated concrete,and ordinary mortar aerated concrete aerated concrete,and drywall.The results show the heat transfer coefficient of he special mortar aerated concrete with the 3 mm to5 mm thick of special mortar interface,and fiber mesh cloth laying in the middle,and the 10 mm thick of thick special mortar surface,is less than 1.0 W/（m-2·K）,and meet the regulatory requirement.
