| Abstract: | The heat-conducting property of the wheat straw-based sandwich wallboard was evaluated with finite difference method and intergal transformation method and compared with the traditional construction brick wall in this paper. The results indicated that the wheat straw-based sandwich wallboard had better property of withstanding the difference of the outdoor environment than the brick wall, which was about 8 - 10 times of brick wall. In addition, the heat conductance of the wheat straw-based sandwich wallboard can meet the national demand of 50% energy saving of new building materials. It has good heat insulation and can be used either in interior or exterior for buildings and will have a bright future in China. |
