生土围护结构的等温吸湿性能的实验研究

Experimantal study of moisture absorption isotherms of adobe building materials

生土围护结构建筑是一种独特的生态型居住建筑.为了定量地研究其室内热湿环境,确定生土围护结构建筑材料的热湿物理性质参数是一项基础工作.建筑材料的吸湿特性可以用材料的等温吸湿曲线表征,本文通过实验研究了生土围护结构建筑材料的等温吸湿过程,利用计算机软件进行了曲线拟合,得到了生土建筑材料的等温吸湿曲线函数关系式,为定量地研究生土建筑室内热湿环境奠定了科学基础.

The adobe building in China is a unique residential building in the world. It is fundamental work to determine the thermal and moisture properties of adobe building materials for evaluating the indoor thermal and moisture environment of adobe buildings. The moisture absorption isotherms of building materials are important for studying the adsorption process of building envelope. Experiments have first been conducted to study the moisture absorption process of adobe buildings. By using the commercial software to do the work of curve fitting, this paper proposes the formula of the moisture absorption isotherms of the adobe building materials. The work helps lay the foundation of dynamic modeling of the indoor thermal and moisture environment of the adobe building.
