建立一种操作简单、易推广的实验方法,测试建筑材料多孔介质的导热系数、孔隙率、定压比热以及密度等基础热物性参数。通过实验测试建筑材料混凝土的干燥密度、干燥定压比热容、干燥导热系数及孔隙率等参数值,验证此实验测试方法的可行性,为推动建筑材料多孔介质热湿迁移物性基础数据的进一步完善提供收集依据。
A simple and easy to popularize experimental method was established to test the basic thermophysical parameters such as thermal conductivity, porosity, specific heat at constant pressure and density of building materials porous media. The experimental density of drying concrete, specific heat capacity of drying at constant pressure, coefficient of thermal conductivity and porosity of building materials were tested to verify the feasibility of this experimental method and to provide further improvement of basic data of physical and chemical properties of building material porous materials Collecting basis.
