摘要

摘要: 采用冷、热箱热流计法测量植物纤维增强碱矿渣胶凝材料墙体的热工参数。选取墙体尺寸为780 mm×950 mm×190 mm，利用热电偶和热流计分别测出墙体两侧温度和热流，再用静态法计算，得到墙体的导热热阻0.408 m²·K/W、传热系数为1.792 W/（m²·K），进而计算得到墙体的导热系数为0.136 W/（m·K）。与空气导热系数0.84 W/（m·K）和混凝土墙体的导热系数1.74 W/（m·K）相比，植物纤维增强碱矿渣胶凝材料的导热系数更小，表明植物纤维增强碱矿渣胶凝材料具有良好的保温隔热性能。

Abstract: The thermal parameters of the wall made of plant fiber-reinforced alkali-activated slag cementitious material were measured through the cold and hot box heat flow meter method. The wall size was selected with 780 mm×950 mm×190 mm, and the thermocouples and heat flow meters were used to measure the temperature and heat flow on both sides of the wall. Then, the thermal resistance 0.408 m²·K/W and heat transfer coefficient 1.792 W/(m²·K) of the wall were measured by the dynamic method and the static method, respectively. Finally, The thermal conductivity of the wall was calculated as 0.136 W/(m·K). Compared with the air thermal conductivity of 0.84 W/(m·K) and the thermal conductivity of concrete wall of 1.74 W/(m·K), the thermal conductivity of plant fiber-reinforced alkali-activated slag cementitious material was lower, which could prove that the fiber-reinforced alkali-activated slag cementitious material had good thermal insulation performance.
