摘要
近年来泡沫混凝土作为一种无机保温材料倍受关注,然而关于泡沫混凝土导热系数模型的研究甚少。本文首先介绍了几种常用的多相复合材料导热系数模型,然后将各种模型用于泡沫混凝土导热系数试验数据验证和研究并进行比较。研究结果表明,文中所提出的导热系数模型适合特定配比的泡沫混凝土,且因其具有两个可调参数而具有很大的应用潜力。
Foamed concrete is considered as a promising inorganic thermal insulation material.However,studies on thermal conductivity models for foamed concrete are limited.In this study,some thermal conductivity models developed for heterogeneous material are introduced and performances of them are investigated through test data in literature.It was demonstrated that the model proposed is suitable for predicting the thermal conductivity of foamed concrete studied.
