Abstract

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.
