摘要 在Cheng-Vachon模型的基础上提出了一种针对由连续相和分散相组成的两相复合材料的新导热系数模型。通过引入一个新的参数,即分散相的修正体积含量来改进Cheng-Vachon模型不适用于分散相体积含量较大的缺点。使用新的导热系数模型预测泡沫混凝土的导热系数,与实验结果的对比表明,新的模型可以准确预测泡沫混凝土的导热系数。 A new theoretical equation for the thermal conductivity of two-phase composite materials was proposed. The Cheng-Vachon equation was modified hy introducing a corrected volume fraction of uniformly dispersed filler. The new equation was used to describe thermal conductivity of foamed concrete. It was demonstrated that the equation is effective. Key words
